HYD FILTER (KU-6661136120)
Description:
Protect your Kubota hydraulic and hydrostatic transmission system with the genuine Kubota KU-6661136120 hydraulic oil filter, engineered to OEM specifications for dependable filtration and long-term hydraulic system protection. Designed for use across a wide range of Kubota compact tractors, HST models, front mowers, and zero-turn equipment, this heavy-duty hydraulic filter helps remove harmful contaminants before they can damage sensitive hydraulic pumps, valves, steering components, and transmission assemblies.
Hydraulic systems rely on clean fluid to maintain smooth operation, responsive steering, and reliable hydrostatic performance. The 66611-36120 filter is built using durable filtration media and reinforced construction to capture metal particles, sludge, clutch debris, and other contaminants circulating through the hydraulic system. Regular servicing helps maintain proper hydraulic pressure, improve HST efficiency, and reduce costly component wear.
This genuine Kubota filter is widely fitted across older B-Series compact tractors, G-Series garden tractors, and ZD-series zero-turn mowers, making it an essential preventative maintenance component for agricultural, landscaping, and groundcare equipment. OEM Kubota filters are specifically engineered for correct bypass pressure, oil flow characteristics, and long-term reliability under demanding operating conditions.
