DIY snowcat build

[MontanaTweak]

First test. Drive around the house, nothing broke. I’ll call that a win. Hard to drive with no seat. Lotta work yet do. I know open differentials aren’t the greatest but there are hundreds of lightweight builds similar to this that the Russians are doing and finding an OC4 or similar is impossible.

Engine: Yamaha RX1 with added radiator/blower
Drive: Stock CVT plus gearbox to “chain drive” open differential from 1 ton.
Steering: Dual caliper per rotor.
Belts: 220-2 ply x 0.36” thick x 24” wide
Grousers: mild steel 1x1x18

Two laps around the house. Still need to work on track tension, throttle response, and a million other things.
