Solarhome Static Wheel Motor for Hydro Gear HGM-12P-7172 Wright 32410004 Ariens 00882300 04115500 Ferris 23091 5023091 5023091SM Snapper 7046255 Great Dane TCA15078

What It Is

The Solarhome Static Wheel Motor is a replacement drive motor for Hydro-Gear HGM-12P-7172 transaxles, designed for zero-turn mowers from Wright, Ariens, Ferris, Snapper, and Great Dane. It converts hydraulic pressure into wheel rotation, enabling precise, smooth turning and forward/reverse movement on commercial and residential zero-turn mowers.

Fitment & Compatibility

Before buying, verify these three things:

• Transaxle model: Must be Hydro-Gear HGM-12P-7172. Check the label on your current motor—other HGM variants (e.g., HGM-12P-7171) may not match.
• OEM part numbers: Cross-reference with Wright 32410004, Ariens 00882300/04115500, Ferris 23091/5023091/5023091SM, Snapper 7046255, or Great Dane TCA15078. Your mower’s parts diagram should list one of these.
• Wheel bolt pattern & shaft size: Measure the shaft diameter (likely 0.625" or 0.75") and bolt circle to ensure your wheel hub fits. This motor is static (non-serviceable), so it comes as a sealed unit—no internal adjustments.

Key Things to Know

• Quality vs. OEM: Solarhome is an aftermarket brand. While 4.4 stars from 4 reviews suggests decent build, it may not match OEM durability in heavy commercial use. Expect a plastic housing (common for static motors).
• Installation difficulty: Moderate. You’ll need to drain hydraulic fluid, remove the wheel, unbolt the old motor, and install the new one. A service manual for your mower is recommended to avoid air in the system.
• Common gotchas: The motor may not include a mounting gasket or new hardware—order those separately. Also, check your wheel hub for wear; a worn hub can damage a new motor quickly.
• No warranty info listed: Aftermarket parts often have limited or no warranty. Factor that into your decision if you need long-term reliability.

Should You Buy It

Buy this if you have a confirmed HGM-12P-7172 transaxle and one of the listed OEM part numbers, and you’re comfortable with a moderate DIY install. It’s a cost-effective fix for a dead wheel motor on a residential or light-commercial zero-turn mower. Skip it if you need heavy-duty commercial longevity or a full warranty—stick with an OEM Hydro-Gear motor instead.
