I have a "26" pro track model and I think it turns great, if you have the bucket down its harder to turn but when you get to, say, the end of the driveway you just click the front end up and spin it around and then drop it back down again. It has three different notches to lock the height into and then it also has a lock on the right side to lock both tracks but in that mode it wants to just go straight ahead.
With only one track driving in the unlocked mode, isn't the unit always trying to turn? I know it has a differential. Does the differential help it to go straight in the UNLOCKED mode, or do you have to fight it?
