[QUOTE="Land-Tech, post: 23276, member: 1679"] I was finally able to take the new/ old 5635 out to play this weekend. Ran it for 12 -14 hrs but it had this annoying knock in the chain case.Also when I had it in high gear it felt like it was binding or a bearing was on it's way out.The drive stick did not feel right with a sort of delay when you changed direction.Made the drive controls feel jerky. The other stick that controled the hydraulics was tight and smooth. It had one small oil leak on a line to the heater core but tightening up a clamp solved this With 700 hrs the previous owner had changed the oil and maybe the hydraulic fiter. the fuel filter was original and the machine is eight years old. The chaincase covers had never been removed so I knew the chains had never been adjusted.This model of Gehl has a single chain driving each wheel, where in other skids it is usually a single chain that drives both wheels. This setup is seems to be a good idea in that you break a chain,you can still move the machine to a better place to repair.It's not as easy to adjust as the the new Gehls which have gone to the bowtie chain system with the single chain and can be adjusted without going into the case.My Mustangs were this way and pretty convenient.
