Hydro-Gear 52114 Transmission Oil Filter – Replaces 109-3321 / 21545100

Hydro-Gear 52114 Transmission Oil Filter

This spin-on hydraulic transmission filter helps remove debris from the fluid circulating through compatible serviceable Hydro-Gear transaxles. It is intended for selected ZT-series drive systems—not for engine air filtration.

Fits

• Selected Hydro-Gear ZT-2800, ZT-3100, ZT-3200, ZT-3400, ZT-3600, and ZT-3800 transaxles that specify filter 52114
• Does not fit every Hydro-Gear transmission; verify the filter number in the mower or transaxle parts record

Confirm Before Ordering

• Match 52114 or an explicitly listed OEM cross-reference.
• Confirm the mower model, serial range, and installed Hydro-Gear transaxle model.
• Do not select a hydraulic filter by appearance alone.
