Transaxle compatibility can vary by mower series, deck size, left or right side, serial number, hydro drive configuration, mounting hardware, pulley setup, brake linkage, and parts manual revision. Left-Side Transaxle Fitment Note This part is listed as a left-side transaxle for compatible 60" and 61" models where specified. Zero-turn mowers commonly use different left-side and right-side drive units, so do not order by mower model alone. Confirm the left side from the operator’s seat and match your original transaxle part number before ordering. If your mower needs a right-side transaxle or uses a 52" deck configuration, this may not be the correct replacement. When Should You Replace a Transaxle? Replace the transaxle if the original drive unit is leaking, weak, noisy, slipping, damaged, overheating, or no longer providing smooth drive power. Drive issues may also be caused by belts, pulleys, linkage, brake components, hydraulic oil condition, or adjustment problems, so proper diagnosis is recommended before replacement.
