Title:
FILTER-HYDRAULIC (KU-W21TSHTA20)
Description:
Protect your Kubota hydraulic and hydrostatic transmission system with the genuine Kubota KU-W21TSHTA20 hydraulic filter, engineered to OEM specifications for superior hydraulic oil filtration and long-term system reliability. Designed for Kubota compact tractors, front mowers, garden tractors, and specialty utility equipment, this heavy-duty spin-on hydraulic filter helps remove damaging contaminants before they can circulate through pumps, valves, steering systems, and hydrostatic transmission components.
Hydraulic systems operate under extremely high pressure and depend on clean oil to maintain smooth, responsive performance. The W21TS-HTA20 filter is built with high-efficiency hydraulic filtration media and reinforced steel construction to capture harmful debris including metal particles, clutch material, sludge, and contaminants generated during normal operation. Regular replacement helps maintain stable hydraulic pressure, smoother HST operation, responsive steering, and reduced wear on expensive hydraulic components.
This genuine Kubota hydraulic filter is widely used across B-Series compact tractors, F-Series front mowers, G-Series garden tractors, and ST/STV utility platforms. OEM Kubota filtration components are specifically designed to provide correct bypass pressure, proper oil flow characteristics, and reliable sealing performance under demanding agricultural and commercial operating conditions.
