You've got to take control of the engine, turn it on, and throttle it up.

how do you move the tractor

great design just wish it was a bit faster. it has some troubles with hills due to its slow speed

Maybe, but it'd have to be so different it wouldn't be "this type of model".

Is it possible to create a offroader using this type of model? as in the wheels have suspension and use a rope cog to turn create speed or a propeller?

yea. for me i just use one and i cant use any others at the same time. but one is well over enough for me usualy.

There's more than one because when used together their power adds. You should check if you have all the mods, and are not spawning it clipping into anything.

well in my worl when i spawned it in the stearing part just spun at turbo speed for no reason and bounced the creation around like mad then my game crashed. that was the first time i spawned it in. the creation might not need fixin it could just have been a faulty spawn. also on your tractors why are there more than one controlable rope drum on the stearing?

I've never had it crash my game, I've never heard of it doing that before. If you give me more information, perhaps I can tell you why it's doing that.

nice design but it crashes the game.

well good work i'll say

Lots and lots of testing.

how on earth did you build that!
