My 2004 cub cadet zforce 50 is now gone through 2 left hand hydro gear transmissions. At $700 repl and only 445hrs on the mower there is obviously a problem. So far all contacts have went unreturned. I have exhausted all possible problems outside the pump and even changed the oil in the pump. There is no physical damage to the motor that I can see. I am afraid I have a strong running, good cutting mower that is destined for the scrap yard because of 1 obviously *** transmission. Has anyone else had any luck with mtd or hydro gear.
