I have a 2011 Cub Cadet LTX 1045 with 160 hours. The independent shop that worked on it recommends we "get rid of it" soon as Cub Cadet has a problem that they know about, but haven't produced a replacement part, so essentially when the part needs replacing, the tractor is toast. The wife picked up the machine from the shop and I haven't talked with the mechanic. I believe he's referring to the case at the bottom of the engine that has worn from the shaft powering the belts. If it's a common problem, is this what he is referring to? Shouldn't a machine last longer than 160 hours?
