i recently bought a 2003 kubota kx 121-3 to use during a house i am going to build. I noticed the upper roller on one side is making noise. How do you determine the condition of this roller and lower rollers. I spun it by hand and it felt gritty like a bad bearing but had no play. The track on this side is making a clanking noise from this roller the other track is quite. Also my tracks are at about 40% with tears and cracks in them and everyone i talked to says run them till they are smooth or break/split. Any advice on doing touch of painting on the rops gray on the undercarraige and counter weight.
