Hydro-Gear 1015-1081R ZT-5400 Hydrostatic Transaxle
Hydro-Gear 1015-1081R ZT-5400 Hydrostatic Transaxle
Commercial-grade drive power packaged as a complete integrated transaxle. The Hydro-Gear 1015-1081R belongs to the ZT-5400 powertrain family, built for demanding zero-turn applications where controlled ground speed, durability, and serviceability matter.
The complete number—and especially the R configuration suffix—must be preserved when matching. A similar ZT-5400 unit may be intended for the opposite side or use different axle, brake, control, input, gearing, or mounting details.
Why This Matters
A heavy-duty transaxle is part of a matched machine system. Installing the wrong configuration can create fitment, control-direction, tracking, or drivetrain problems even when the housings look alike.

Before You Order
Match the complete part/build code and verify the original component, equipment model and serial number, plus all relevant shaft, axle, control, port, brake, rotation, mounting, and revision details. A partial code or similar appearance is not enough to confirm fitment.
