I started to restore a joystick controlled Snapper Zero Turn but the deck was just too far gone + I learned the drive units were no longer serviceable. I can confirm
the drive units are in good condition because I drove the mower around to get them warm enough to confirm they are in good condition. A plastic cap on the plastic
oil reservoirs has a worn place(vee belt rubbed it) on one of the drive units. Easily repairable with epoxy.
Mower: Snapper Model YZ13331BE. Snapper Part Number 7029129YP(superceded Part Number 7029136)
OEM Info: Eaton Model X778-011
