There are 4x4 truck and 4x4 stock tractor classes when the farmers bring out
their stock tractors... I don't think there is any rule against FWD. but I
would think that the load shift up the transfer sled would pick the front
tires off the ground before you could get a full pull. Figure that the weight
is transfering off the wheels on the sled and on to the hitch point and the
rear wheels...
I actually wanted to build a tractor/sled with technic before the Power Puller
was announced... sort of bummed me out when they released it! :)
