I'm a mom that has a bobcat we use for our horse corrals, recently I offered to do some work moving dirt in trade for horse training. I put about 25 hours in & then the right wheel started slipping & then stopped turning when I pushed the arm forward, it won't go in a straight line forward or in reverse. I looked in the manual & it said it could be the linkage, or the motor or the hydraulic pump. If it is one of the latter 2, is there a source for rebuilt parts out there? I'd appreciate any help or suggestions! Thanks!
