My first motor dog. I decided to do for trips through the forest. Initially, there was only a platform and an engine. Later added a front shield (ram). A very convenient thing, because sometimes bushes and not big trees run across the road. 4-stroke engine 16 l. from. That would have been enough for 9 hp. Well, as they say, it was set. True, I had to grind the engine shaft and mill the keyway. Factory leading and driven shaft, track 500 mm. I did not put the gear because read reviews that do not behave very well in the cold. Set the variator "Safari".
After test trips, there was a need to make a snow protection casing. And things can be put and the protection of the variator, belt. The casing frame is made of PVC pipes. (left from the repair). It turned out durable and easy. Material fabric "Thesa". Sleds bought but modified installed runners from 4 mm steel.
I will be glad to hear advice on finalizing or improving the design.
