A lot of people go out in groups, and if you were riding with another snowmobile, you can easily have it tow yours back to the workshop for repairs.
Before you use another snowmobile to tow your broken one, you need to remove the drive belt from your snowmobile. Moreover, if possible, you should use a proper tow rod or bar instead of pulling the broken snowmobile with a rope or a chain. This is to minimize risk of damage to both machines and injuries to the riders.
Ideally, there should not be a lot of load on the machine which is going to be towing the broken one. If the workshop is not too far, a person can stay back while one rider takes the broken machine to the workshop and returns for the other later on.
It is recommended that the broken snowmobile has one rider on it to steer it and apply the brakes to manage speed. This is very important when you are towing the machine using a rope or a chain.
The rider on the working snowmobile needs to go really slow and steadily and if possible, put up flags and reflectors to be visible and obvious to others. This is important to prevent any accidents or mishaps in case visibility is low due to snow fall or wind.
If you are going to be crossing a road, be very careful, because you are not going to be moving very fast. It is recommended that one rider gets off and walks across the road to help the other get across.
