seems like in some ways with a high quality belt, the belt drive might be more forgiving than a shaft?Hey Keith,
We have a local John Deere dealer here in town and the son of the owner competes in the pulling circuit here. He runs an older John Deere 240. I don't know if this is a glowing endorsement for the 240 but I would suspect that junior has his pick of whatever the guys have in the shop. Don't know enough about the older John Deeres and that "Variator Drive" but I did speak to a couple guys who saidit works well for pulling.
A lot of guys use Wheelhorse tractors which are also belt drive. They have what they call a cheater pedal or cheater stick. (some rules required both hands on the steering wheel while pulling) When/if the belt starts to slip as the sled loads up, you mash the pedal and it tightens up the pulley.
Yes, belt drives work, but we've had that conversation.
