I have a Snapper Pro Crusier Model # MZM2200KH with a broken housing on the Left Hand transaxle. Tire went down while mowing and it went unnoticed long enough for the transaxle to hit a rock which cracked the housing and sent a chunk of metal into the gears. So I guess I needs the planetary gears inside as well. This part is unavailable from Snapper and the mfg. Eaton. My only hope is to find one used. The Snapper part number is 7059154. If anyone knows of a cross referance for this part that would be another option. I also have been trying to contact as many Snapper dealers as I can in hopes of finding someone that has the part from an old mower or knows the location of a mower to get the part from. My pump is good. It is the physical damage to the transaxle that has me down. I really hate to buy a new mower, this one has been such a great mower. Everything still works like new. Everything but the LH Transaxle that is. If this part can't be located, I may be parting out this mower.
