[QUOTE="roadkill, post: 3408, member: 543"] Hi Gents, I recently bought a well-used 743. It had a hydraulic leak, crept forward, and the lift arms come down on their own. The dealer nearest me is fairly new, and doesn't have alot of Bobcat knowledge. They are very nice, though. The leak happened to be the one hose you have to take the engine out to replace. (They didn't know you had to remove the engine, nor did I!) It used to creep straight forward, after they adjusted it it creeps in a backward circle!
