Hydro-Gear 32410004 HGM-12P-7172 Hydraulic Wheel Motor Assembly

The Hydro-Gear HGM-12P-7172 is a hydrostatic wheel motor designed for integration into commercial zero-turn and stand-on mower drivetrains. It functions as the final drive unit, converting hydraulic flow and pressure from the hydrostatic pump into rotational torque at the drive wheel. This unit carries the OEM part number 32410004 for Wright Manufacturing and John Deere platforms. It features a static housing configuration typical of the HGM-P series, utilizing an axial piston rotating group for high efficiency and torque density. The motor is bi-directional (CW/CCW) to support forward and reverse operation. Mounting interface and port configuration conform to the specific OEM chassis requirements for Wright Stander, Ariens, Gravely, Ferris, Great Dane, Snapper, and Everride models. Cross-reference interchange includes Wright service replacement 32410022. Verification of the original equipment part number against the machine serial number plate is required prior to installation to ensure correct fitment.
