Looking at a IH255 compact with 2000 hrs and a King Cutter finish mower. Tractor looks good but differincial lock has been taken off. Did they have problems with these? Supposed to be abt an 88 model made by Mitubishi. How many hrs. can you expect to get out of the engine? Dealer says they over heat if worked hard. He also says the mower has a weak gearbox but he is selling Woods. Any info will be appreciated.
