Well, the torque an engine produces can be multiplied (by gearing); the

of force. A force that causes no motion, produces no work.

I wish manufacturers would be more up front about publishing WEIGHTs.
One has to dig deep into specs to find this out, for tractors or other
vehicles. All the multiplied torque in the world can only move something
if it has TRACTION, a function of weight and friction.
