The person who converted the 400 and plow scripted it as a plow with create field, It would need to be re-scripted as a windrower to work on snow maps as snow is just white wheat windrow.

I tired your mod in a snow and it didn' plow snow at all, It just has create a field, so can you make it so it plow snows??, as it's a BearCat plow that is used for seismic work and work on ski hills. Other than it doesn' plow snow, it not a bad mod.
