I believe there are both. Do you have a hand throttle? I think capstans make sense for farm work, hence my question about logging, they are slow, steady and ideally need two people. My take is that they are useless of self recovery as you may have to run the engine at an excessive angle and someone has to be keeping tension on the rope the whole time so its a 2 person job, also the drive engagement handle is right next to the capstan. If its for posing down the pub, no problem but don't waste time connecting the drive as it looks the same with or without it and its safer without. There's a video o youtube of a series using a capstan for recovery at an off road event, can't find it at the moment. Basically it's "we'll come back later and see how its going". its very slow.
