Mower is 4 years old with 543hrs. Last year I replaced the left side wheel motor. Yesterday the right side hydraulic pump failed. I called the dealer and they said 7-10 days just to get the pump. Not good, very poor parts distribution. What are we supposed to do w/out having our mower for 7-10 days? Have a backup mower? I'm sorry, 7-10 days just to get a part is just not right. I'm not complaining about having to replace parts or the $688.00 pump, i'm complaining about the availability of such parts.
