(Replaces ZC-DUBB-3D5A-3BPX, 107-2466, ZC-DUBB-3D5A-3DPX)
The Hydro-Gear ZC-DUBB-3D5A-3WPX RH EZT hydrostatic transaxle is a genuine OEM right-hand integrated drive unit designed for compatible zero-turn lawn mowers. This EZT (ZT-2200 series) hydrostatic transmission combines the hydraulic pump, motor, and axle into a sealed assembly that delivers smooth variable speed control and precise steering performance on the right-hand side of the mower.
Engineered to original Hydro-Gear specifications, this unit provides dependable torque output, consistent ground speed control, and long service life in residential zero-turn applications.
What is this part & what does it do?
A hydrostatic transaxle transfers engine power to the drive wheel using hydraulic pressure instead of traditional gears. The EZT system allows seamless forward and reverse control with variable speed operation. This RH (right-hand) unit powers the mower’s right drive wheel, enabling zero-turn maneuverability and proper tracking. Replacing a worn or failing right-hand transaxle restores smooth steering response and consistent drive performance.
