Do-it-yourself ski cutter drawings. Gabosha-light: how to prepare the track quickly, cheaply and with high quality. Creating and maintaining a ski run
Probably no one will argue that skiing requires a track. Let's look at the different ways of laying ski tracks. So, for laying ski tracks, there are three main ways:
There are three main ways to lay a ski track:
1. Laying a ski track with skis, that is, walking through snowdrifts on skis, leaving behind parallel tracks. If another hundred people pass along this track, then we get a ski track acceptable for walking, in some places a curve, in some places interrupted by traces of the fall of various parts of the body of the skiers. This method is inexpensive, but very labor-intensive, and as a result of all the efforts, the ski track is of little use for real skiing.
2. Ratrak. This is a large snow bulldozer with wide tracks, which will compact the snow, level the snow surface and push the ski track in it if it has the appropriate devices. This method is good in terms of the quality of the prepared ski track, but it is very expensive, it requires large financial costs for the snowcat itself, storage space, maintenance costs, and a specially trained driver.
3. Laying ski tracks with any snowmobile. Better, of course, is a utilitarian snowmobile, or as they are also called a worker. To lay a classic track using a snowmobile, you will need a track layer, or, as skiers also call it, a cutter. And for skating - a harrow for skating. This method is not too expensive, but very effective. The cost of preparing the route with a snowmobile is significantly lower than preparing it with a snowcat. The quality of the ski track is comparable to the snowcat, which allows competitions of any level. In it, the main component is a snowmobile, which pulls the devices laying the ski track. The price of a snowmobile suitable for laying ski tracks is from 160,000 for a domestic Buran to 300,000 for a Japanese Yamaha.
XCSPORT offers ski-laying devices for sports enthusiasts - skating harrows and cutters for classic skiing. And again, new items, now it is a universal harrow for laying ski tracks for free running.
Classic track cutter
Cutters, track layers and harrows are constantly tested in various snow conditions and improved. At the moment we offer a new model of cutter and harrow.
The new versatile ski cutter design has been tested in a variety of snow conditions. The cutter worked both at a snow cover height of 10 cm and on dense crust, and on deep loose snow, leaving a beautiful smooth track everywhere.
The design of the XCsport torch uses the most successful solutions of different torches and is assembled in one product:
- hinged mount allows you to turn the cutter from the "sledge" position to the "cutter" without unhooking it from Buran,
- adjustable height of the drawbar, allows you to use it with different snowmobiles,
- the cutter can work in pressing (for loose snow and little snow) and in cutting (for dense snow and crust) modes,
- a large snow outlet allows you to lay a ski track, even on wet, coarse-grained and sticky snow,
- the weight of the cutter is not more than 40 kg,
- a rigid drawbar and deep guides hold the cutter steadily even on an inclined surface,
- dimensions of the cutter and a removable drawbar, allow it to be easily transported in the trunk of a car,
- powder coating reliably protects against corrosion and prevents snow from sticking.
Ski cutter with snow wing
Cutter dimensions:
Torch width (without drawbar) 56 cm
Cutter length (without drawbar) 90 cm
The distance between the tracks along the axes of the track is 24 cm,
track depth 45 mm,
width at the bottom of the ski tracks 5 cm
width at the top of the ski tracks 11.5 cm.
New photos of the universal ski cutter and the skating harrow have been published in the photo album of our website and on the skitrack website.
We are sure that the more cutters will be made, the more beautiful and smooth tracks will surround us, and more people will come to ski trip. The number of snowmobiles among citizens is growing every year and just imagine what will happen if every lucky owner of such a snow machine spends 30 minutes to lay 5 km of ski tracks near his house or summer house.

Used car tires are used in the snow roller. Used car tires are not included in the scope of delivery. The use of new tires is not recommended by the manufacturer. The supply of used tires and assembly of the rink can be done for a fee.
It's summer, but the organizers of the competitions and fans of skiing are already preparing the "sledge". It would be more correct to say devices for laying ski tracks - harrows for skating and cutters for classic skiing. And although the sun is shining outside the window, and weather forecasters predict heat, the skillful hands of our inventors are creating new masterpieces of snow paving equipment, looking forward to entering the snowy expanses.
Few people want to trample snowdrifts knee-deep, so to lay a classic ski track, you need a ski track layer, or, as skiers also call it, a cutter. True, a snowmobile is still needed. As you know, a high-quality classic ski track cannot be prepared without a special ski cutter. We offer you our experience in manufacturing a universal cutter.
The new versatile design has been tested in various snow conditions. The cutter worked both at a snow cover height of 10 cm and on dense crust, and on deep loose snow, leaving a beautiful smooth track everywhere.

TORCH DIMENSIONS
We are sure that the more cutters will be made, the more beautiful and smooth ski tracks will surround us, and more people will go skiing. The number of snowmobiles in the population is growing exponentially every year, and just imagine what would happen if every lucky owner of such a toy spent 30 minutes laying 5 km of skiing at his house or cottage. Video of the cutter for laying the track (the cutter of the 2007 model is shown in the film). |
Attention!!! From December 10, 2010, a new model of the 2011 ski cutter will be produced. The main difference from the old model is the ability to upgrade. You will be able to attach torch extenders and additional knives. Additional accessories for the cutter will be sold separately and will be available soon. The buyer will be able to decide for himself whether he needs a standard or complete set.
Following the recommendations of the authors and focusing on their drawings "Scraper" and "Plow" (from the magazine " skiing”), we made samples of these devices and tested them in practice. (produced under "Buran") During operation, some imperfections of the mentioned devices were revealed.
As you know, snowmobiles "Taiga" or "Buran" on a hook can tow hundreds of kilograms, therefore, the mass (weight) of devices is not a problem. The material for the devices should be only metal, and not boards and plywood, since this increases reliability, there is no need for additional cargo, and in the manufacture, you can basically use electric welding. This design is much more reliable.
The length of the "Scraper" should not exceed 100 mm, otherwise it will not allow it to fit into the track of the "Buran" on turns, and will hang over the depressions.
A large area of support leads to a significant accumulation of snow on top, which will not crumble, especially when the air temperature is around zero. The “Scraper” does not perform its main function - breaking, loosening and mixing snow - on a dirty, frozen ski track, as it slides along individual scallops, leaving behind dirty uneven ruts.
The knives in the "Struga" in the described version are located at a very obtuse angle, so they do not cut the ski track, but rather rake the snow in front of them, especially hard, or chip off snow layers.
The absence of guide skids behind the knives, protruding beyond the edge of the Struga platform, eliminates the possibility of smoothing the cut track.
In addition, there is no “apron” in the design, so the snow thrown out by the knives is not taken to the side, but falls on the ski track. The disadvantage is also too big sizes windows through which cut snow falls. The windows must be exactly the width of the knives.
And, finally, in the proposed device, the issue of transportation from the storage place to the route is not thought out.
Having analyzed all the shortcomings of the “Scraper” and “Struga” devices, we worked on individual nodes and improved the design as a whole.
We bring to the attention of readers options for devices "Struga-cutter" and "Harrows". It seems that with the help of the given drawings, those who wish will be able to manufacture devices that we have repeatedly and successfully used to lay the ski track.

Oddly enough, living in the 21st century, using such benefits of civilization as the Internet, mobile phone, hypermarkets and charter trips to the sea to Egypt, it seems to many people that the ski run is a kind of path in the forest, rolled by the feet of the skiers themselves, or , in extreme cases, prepared by Buran with a chain-link bed net attached to it and a cutter welded in garages. And prepared for important events only a couple of times during the winter.
No, it's not! A ski track is a sports facility that requires creation, maintenance and preparation.
CREATION AND MAINTENANCE OF A SKI ROUTE
The ski track in summer can be a jogging and cycling track.
The creation of a ski track can take place both “from scratch”, and on the basis of existing paths or historically established circles (piste).
First of all, you need to determine what the track is created for - for walking, for walking and training, or for walking, and for training, and for competitions. It is also better to immediately decide whether the track will be all-season - for running, cycling, skiing - or only winter.
It's usually easier to get support from people and organizations for large, thoughtful projects. Therefore, in order to save time and resources, it is better to immediately plan to make an all-season competitive track with cuts. Cut-offs will shorten the length of the track and/or remove from the track descents and ascents that are difficult for children and beginners. Also, cuts will allow to exclude “winter” sections of the route - for example, sections passing through wetlands and therefore unsuitable for summer use.
Of course, it is ideal if the competition track meets the homologation requirements of the International Ski Federation (FIS).
These requirements are determined for different distance lengths and different disciplines. cross-country skiing- for example, the following parameters:
* The length of the laps of the tracks and how distances of various lengths are combined from them. The example below is a schematic diagram of a track system that can accept all race formats. The system consists of two different circles - one for the skate, the other for the classic, each 3.75 km long. Thanks to the cuts, you can make distances of 2.5 km and 3.3 km, as well as a sprint distance. These two laps may also be considered as one 7.5 km lap, suitable for both individual and common starts, provided the track is wide enough.
 |
* The width of the prepared track for various disciplines - for example, a duathlon requires a track 12 meters wide.
* A set of heights on tracks of various lengths, for different disciplines;
* The ratio of the length of ascents, descents and plains on the slopes - they should be approximately one third each;
* The location and layout of the ski stadium - for example, athletes should finish towards the south so that the sun does not interfere with the work of photographers, you need to take into account the location of spectators, commentators, lubrication booths, ski testing area, warm-up circle, etc...
In any case, you need to immediately determine how wide the track will be, and stick to this width when working. If we talk about the minimum, then the width of the "corridor" of the route should be at least four meters between the trees. Since it is not safe to roll the track close to the trees, the prepared track canvas in winter will turn out to be about three meters wide. This is an extremely small width to go parallel with the skate and the classics. At competitions on such a track, the participants may be cramped. With such a width, there is a risk that the classic track on the slopes will roll obliquely with the traces of the skis of people skating.
If the classic track rolls up in the footprints of skiers skating, then the skiers walking classic move, there will be difficulties with holding skis. For a good hold classic skis you need a smooth, dense ski track surface. Therefore, you need to strive to increase the width of the track, especially on the rises.
ROUTE SURFACE
In order for the snow surface of the track to be smooth, it is necessary in the snowless time to strive to level the track in the transverse direction and strive so that the track is also aligned in the longitudinal direction, without sharp bumps and pits. Turns on the track should be smooth, with good visibility, this is important both for trainees and skiers, and for drivers of cars preparing the track.
DRAINAGE FROM THE ROUTE
In order for the track to be solid for running and cycling, as well as for the snow to lie on the track longer, it is necessary to divert rain, melt and groundwater from the track.
In early spring, the ground is frozen, and melt water cannot go into the ground. If the melt water is under the track snow, then the snow will melt in it, so it is necessary that the water does not stagnate on the track.
The easiest way to divert water from the track is with the help of drainage and drainage grooves. At the same time, there should not be depressions on the track bed where water could collect - the track bed in the section should not be a gutter, it is better that the track be slightly convex in the section so that water rolls off it.
Drainage grooves divert water from the track bed and drain the track bed. Drainage grooves must be dug out, taking into account the fact that over time they will swim, silt. It is necessary to make drainage grooves at least 40 centimeters deep, and preferably deeper. The drainage groove in the section is V-shaped with a straight (900) or obtuse angle at the point of convergence of the walls of the groove. Drainage ditches are dug along the edge of the track, as close to the trees as possible, primarily on the side of the track from which water enters the track. It is desirable that the grooves be on both sides of the track, this contributes to the fastest drying of the track in spring and after rain.
In addition to drainage grooves, it is necessary to plan and carry out a system of drainage grooves - grooves where water will drain from the drainage grooves. Drainage grooves must be made on each section of the route, where there is a transition from descent to ascent, where all the water on this section of the route merges. A pipe with a diameter corresponding to the expected flow must be laid across the route. If there is no pipe, dig a groove across the route and, so that the groove is preserved and suitable for driving, put several thin, straight tree trunks with a diameter of 5-10 cm into the groove. Aspen is well suited for this. To prevent the pipe from silting up, it is necessary to make a hole on the side of the pipe where the water enters, at least one and a half times the cross section of the pipe.
In continuation of the pipe, lay a drainage groove, preferably along the line of the maximum slope of the terrain, diverting water to the area located below this lowland, ensuring that the level difference reaches at least 50 centimeters. This can be difficult in wet, flat areas - in order to achieve sustainable water drainage, it may turn out that you need to dig a groove 100 meters or more in length. Since the soil in the forest is saturated with roots, sometimes with stones, it is recommended to use high-quality, expensive shovels and hoes with a composite handle for work.
VEGETATION ON THE ROUTE
In the summer, grass and small shrubs can grow on the track, which will interfere with the movement of runners and cyclists. This vegetation must be harvested 3-4 times per season. To do this, you can use both a regular scythe and a gasoline trimmer with a fishing line, or, if there is a lot of shrubs, a trimmer with a disc. To work with the trimmer does not require special skills; True, you will have to take a supply of gasoline diluted with oil on the track. The scythe requires beating, sharpening and the ability to mow smoothly, with your back, not including your hands. In the old days, mowing was considered by skiers as an excellent means of training.
It is not necessary to mow the entire track, it is enough to mow a strip one pass (stroke) wide with a scythe or trimmer, trying to position the track path in the middle of this strip. When the snow falls, the rest of the uncut grass will duck under the snow and become an excellent base for the first skiing outings.
From time to time, trees fall on the track - either from old age or from strong winds. This happens especially often in the spring and autumn periods, when the soil is saturated with water and becomes less dense. In order to maintain safety at work, it is better to go out to clean trees together and with a chainsaw.
ROUTE DEPARTMENT
Trail backfilling is a luxury that helps keep the trail drier and harder, and the foot/wheel track doesn't create a groove that gets in the way of skiers at the start of winter. Also, backfilling the track helps to dry the track faster in spring or after rain and to the fact that less grass and shrubs grow on the track. The track should be poured at choice or in a mixture - sand and gravel mixture, sawdust, slag. Sawdust and slag help to ensure that grass and bushes do not grow on the track. It is desirable to pour the track over the entire width of the track, with a thickness of 10-30 centimeters. If it is not possible to fill the entire width, it is necessary to fill first of all problematic, wet places, at least a meter wide, along the trajectory of runners and cyclists.
SKI ROUTE PREPARATION IN WINTER
The ski run in winter requires preparation in order to:
1. Create and maintain a smooth, dense snow surface on the track;
2. Provide a pleasant and safe ride;
loosening the surface of the snow on the track, if the track is frozen,
rolling and compacting the top layer of snow, if the track surface has become loose as a result of a thaw or snowfall;
3. Remove the "wave" that occurs on the track for the classic course;
4. Remove the longitudinal bump that occurs on the track for skating;
5. Prevent the rapid melting of snow in the spring.
Snow on the ski run is subject to the following influences:
1. Time: snow “gets old” - snowflakes crumble into ice floes, the edges of the ice blunt;
2. Temperature differences depending on the weather or the change of time of day: snow either freezes from cold or crumbles from warming;
3. Changes in air humidity: combined with changes in air temperature, they create Various types snow surface;
4. Solar radiation: promotes snow aging and melting;
5. Vapors and heat from unfrozen ground at the beginning of winter: make the snow mass porous;
6. Cold from frozen ground at the end of winter: cements the track;
7. Particles of dust and debris falling from the air and from trees mix with snow and impair ski glide;
8. Water flowing along the ground in spring melts the snow on the track;
9. Skating skiers push and move snow on the track - a “ridge” appears along the middle of the track on a skating track, and a “wave” appears on a classic track.
The process of preparing snow surfaces, in particular ski runs, is based on the process of compaction of snow crystals. A common misconception is that snow is compacted by the weight of, for example, a snowcat or harrow, similar to how an asphalt paver creates a roadbed.
Surprisingly, the specific snow pressure of snowmobiles and snow-compacting machines (it is measured in pressure per unit area) - can be less (50-100 g / sq. cm) than that of a pedestrian (from 200 g / sq. cm and above) , or a skier-athlete skating on an edged ski (150-200 g / sq. cm).
Snow compaction occurs when the snow is mixed with the help of a rotating snowcat cutter or harrow teeth attached to a moving snowmobile, as a result of which the snowflakes lose their “branchiness” and crumble into ice floes, the snow particles are crushed and lie more compactly in the thickness. Daily fluctuations in temperature and changes in humidity do their bit - the snow freezes and becomes dense.
Pushing and compacting the entire thickness of a snowdrift is very difficult, almost impossible. Even a pedestrian does not push through the entire thickness of a snowdrift, and cars moving on snow have several times less specific pressure on the snow than a pedestrian. Therefore, the only effective way to compact the snow cover is to process each layer of fallen snow - preferably several times!
There are three main factors that determine the quality of ski slope preparation, and they are approximately equally important. This:
1. The staff who prepares the ski run,
2. The equipment used to prepare the ski run,
3. Frequency of preparation of the ski run.
EQUIPMENT FOR SKI PREPARATION
RATRAKI
These machines are ideal for preparing ski slopes. The limiting factors are the relative high cost and the need to have a snow cover of 15 centimeters or more. Usually, the snowcat justifies itself where there are artificial snow systems, and from the very beginning of the season a layer of snow is laid, allowing the snowcat to work. To date, 4 manufacturers of snow groomers are represented in Russia - the Japanese Ohara, the German Pisten Bully, the Italian Prinoth, the Italian Snow Rabbit. The remaining brands that existed before either ceased to exist or were absorbed by the above-mentioned manufacturers. The United States has its own manufacturers of snowcats that are not represented in Russia.
OHARA
According to the information stated on the Ohara website, this company does not supply snow groomers adapted for preparing ski slopes.
Pisten Bully 100 (PistenBully 100 - 197 hp) - a comfortable double multifunctional machine for preparing various types of ski and toboggan runs, as well as maintenance ski slopes. Available in three widths - 2.500, 2.800 and 3.100 mm.
These models are equipped with systems with two ski layers for cutting tracks with manual or hydraulic (from the operator's cab) track width adjustment in the range of 70 mm, distance between adjacent tracks in the range of 735 mm. Also, an additional cutter can be installed on each ski layer, which loosens the snow in the strip of the laid track to a depth adjusted from the cab from 0 to 60 mm to obtain best quality(VarioTrackDesigner system).
On the PistenBully 400/600 and Formatic 350 models, it is possible to install both the above-mentioned systems with two ski layers, as well as systems for mass skiing - with three or four ski layers for cutting tracks with track gauge adjustment for the convenience of both adults and children skiing.

PRINOT
Prinoth Husky car with a 177 hp Mercedes diesel engine. designed specifically for the processing of slopes for flat skis and the preparation of small ski slopes. The Prinot Husky with ski liners are excellent machines for laying and preparing ski slopes. Prynot Husky is available in three options widths - 2.5, 2.8 and 3.1 meters. Ski layers are attached to the rear snow cutter of the snowcat. On command from a two-seat cabin, two ski layers can move along the width of the cutter to change the distance between adjacent ski tracks. The change in the width of the track itself (by 70 mm) is also controlled - this is especially important when preparing the track in places of descents and ascents and when creating tracks for children. The wide rear snow plow of the Prenot Husky snow groomer is additionally equipped with special Track Tiller plows mounted in front of the ski-layers. Track Tiller cutters allow you to lay the perfect track regardless of the weather.

Favero
Favero Snow Rabbit 3 (Favero Snow Rabbit 3), equipped with a Japanese Kubota diesel engine with a capacity of 100 hp. - the smallest, lightest and most budget snowcat on the Russian market. The third generation Snow Rabbit is a reliable work machine. Capture width - 2.0 meters, length of Snow Rabbit with accessories - 4.5 meters. The Favero Snow Rabbit can be transported between jobs on a small truck, tow truck or on a trailer with a ramp, without dismantling the tracks. The Favero Snow Rabbit can be equipped with a front blade, cutter, one or two ski layers, and a covered cab. The double heated driver's cab with a large view makes work a pleasure. The engine is equipped with a 220 volt/300 watt electric parking heater and Perkins preheat for a trouble-free start in any frost. Favero Snow Rabbit works great on narrow ski slopes, small slopes, in recreation parks. The Favero Snow Rabbit has a body for transporting materials. The ground pressure of 40 grams per square centimeter - more than half that of competitors - combined with a compact size gives this machine a unique flotation in any snow.
SNOWMOBILE
Snowmobiles are a more budget option than snowmobiles. Moreover, with a snowmobile with a tow hitch, you can start preparing the track almost from the first snowfall.
To prepare a ski track in winter, you need a so-called utilitarian snowmobile with a non-narrow (from 50 cm wide and above) and long caterpillar. Thanks to the wide track, utility snowmobiles have excellent flotation and high tractive effort. It is desirable that the caterpillar be studded, this will greatly help in the preparation of an icy track, such caterpillars are sold separately. Utility snowmobiles are usually equipped with three gears - reverse, forward and front low - it is this gear that is used to prepare the track when in large numbers fallen snow. In terms of layout, snowmobiles with two skis in front are preferable due to better handling.
Examples of utility snowmobiles: domestic Buran and Taiga (with a wide caterpillar), foreign Yamaha Viking series, Polaris Utility Widetrack series, Ski Doo Scandic series (Ski- Doo Skandic), Arctic Cat Bearcat series, Bombardier Lynx Yeti series.
From the point of view of operation and reliability, we have to pay tribute to foreign snowmobiles. The domestic Buran has been produced almost unchanged since the 70s and was popular due to its wide track and low price. Now "Buran" is losing its positions, as its price is approaching the price level of a "fresh" used imported snowmobile.
TRAILING DEVICES
A classic set of trailers for trail preparation:
* Harrow or trellis,
* Cutter for classic skiing,
* Skating rink-drum for rolling snow.
This market is not very developed in Europe, in the USA there are three notable manufacturers, and in Russia this market is in its infancy - the consumer has not yet realized his needs in the field of snow surface preparation.
SNOW-STAR.RU
Supplier of heavy trailers for many years of daily (seasonal) professional use. These devices use elements made of special steel, which ensure the quality of the preparation of the route and the long-term functionality of the devices. All devices are equipped with an emergency release in case the device gets caught somewhere (for example, a harrow by a root or a stump) at full speed of the snowmobile. All of the above determines the relatively high price of these devices. Devices are delivered both assembled and disassembled.
Skating rink SnowRoller- preparation of the track from the first snowfall and in difficult conditions - heavy snowfall or severe thaw. Supplied unassembled, completed on the spot with decommissioned "Zhiguli" tires.
 |
Harrow Plain- designed to prepare the track bed when there is a stable snow cover on the track. It works best at speeds over 20 km/h, levels the track both in the longitudinal and transverse axes, cutting off snow irregularities, including the hump from the ridge and filling in the recesses. Equipped with special steel serrated knives imported from Sweden. The reverse side of the harrow is used when there is a small amount of snow on the track, as well as when working with freshly fallen wet snow and on virgin snow. The Plain harrow is the only passive hitch on the market that cuts through the hump that occurs on the skating track. The emergency release is very important on this device: if the harrow is hooked somewhere at full speed of the snowmobile, then the emergency release will save the driver from hitting the steering wheel with his chest and his face against the windshield, and save the harrow from deformation.
 |
SKITRACKER.RU
Pioneer in the trail preparation market. Thanks to this company, what people used to do for themselves in garages is now freely available on the market, in collapsible form and powder coated. Products are made of low-carbon steel of building grades. This determines the affordable price of these products and limits their strength and durability.
The versatile SNOWPRO skating track harrow has three plug-in modules for different snow handling applications. By removing and installing modules, you can vary the way the snow is handled and the load on the snowmobile. Material: powder coated steel. Drawbar with damper included. The drawbar has a device for hooking to a snowmobile in the form of a steel ring with an inner diameter of 30mm. A universal harrow can be bought in many cities of Russia and ordered from the manufacturer.
 |
Cutter for laying classic ski tracks XCSPORT - designed for laying classic ski tracks; thanks to him, every snowmobile owner can lay a quality track for walking with family, friends and for skiing competitions. The XCSPORT cutter can work in pressing (for loose snow and little snow) and cutting (for dense snow and crust) modes. By rearranging the drawbar to the other side, you can change the way the track is laid in a few seconds. The swivel mount allows you to turn the cutter from the transport position "sled" to the working position "cutter" without unhooking it from the snowmobile.
FREQUENCY OF PREPARING THE SKI ROUTE
This is the second and almost equal to the first factor in the creation of a quality ski run.
The track must be prepared regularly. In Scandinavia, in many places the slopes are prepared daily, despite the fact that the length of the ski slopes in some resorts exceeds 100 km! It is advisable to prepare the track at least three times a week, and in snowfall - every day, while it is snowing. Even if it is not snowing, but the weather is clear, frosty, the track still needs to be prepared.
ROUTE PREPARATION PROCEDURE:
* The first serious snowfall, 5-10 cm of snow fell. Pass 1-2 laps with a snowmobile, make 1-2 tracks along the longitudinal axis of the track. Then, in a day, press down the snow along the entire width of the track with a skating rink.
* Normal, established snow cover, stumps and roots are securely covered with snow. Depending on the width of the route - two or three passes with a harrow with teeth, with a slight overlap; if there is a hillock from the ridge, then remove it with a harrow, it is better to do this by going in the opposite direction. The hillock is most on the uphills, and it is easier for the snowmobile when the harrow removes the hillock while going downhill.
* If the classic track is already with a wave, then roll it up with a harrow and cut a new one; if the width allows, this should be done on the other side of the track or next to it, parallel to the old one.
* It is better to do all the preparation in the evening, in the dark, right after the skiers left the track - there are less chances to meet with skiers, and most importantly, after the preparation, the snow will freeze overnight, the track will be of high quality and fast.
* On slopes, cut the track along the edge so that skiers have the opportunity to leave the track, for example, to slow down. On slopes with a turn - it is better to cut the track along the outer edge to improve the view of the rider from the slope.
* If the track is prepared in the morning, the snow will not have time to freeze and the track will be easier to break.
* If the track is not wide, then periodically during the season you need to make a trip only on a snowmobile - crush the edges of the track along the trees so that there is more space in width to place a classic ski track and a skate track. During such trips, branches hanging over the track should also be removed with secateurs and a saw.
THE ECONOMY OF ROUTE PREPARATION IN GENERAL FEATURES
An example is a 15 km track with 3-5-10 km cuts. Width 4-5 meters - 3 harrow widths on the ridge strip and a classic track - along the edge.
* One trip - 4 hours with changing clothes, gas stations, etc. - Based on this, the employee's salary fund is formed.
* Winter in central Russia - 15 weeks on average 4 trips per week (including snowfalls and competitions) = 60 trips of 50 km (with cuts, etc.) = 3,000 km of run per winter with fuel, oil costs , maintenance, repair and depreciation of the snowmobile and trailed implements.
* The life cycle of a snowmobile and implements is best calculated at 5 years.
Good work to you and human gratitude.
