When your Massey Ferguson’s independent PTO starts losing pressure or you notice hydraulic fluid seeping around the unit, worn seals are usually the culprit. The IPTO system in these tractors takes a beating—operating under high pressure and constant use whether you’re running a baler, mower, or spreader. This small but critical sealing ring keeps hydraulic fluid sealed inside the IPTO assembly where it belongs, maintaining the pressure needed for reliable implement operation.
Key Features
- Precision-molded 56 x 63 x 2mm dimensions for exact fit in IPTO assemblies
- Quality rubber construction resists hydraulic fluid degradation and temperature extremes
- Maintains critical hydraulic pressure for reliable PTO engagement and operation
- Direct replacement—no modifications or special tools required
Built for Real Farm Work
This sealing ring fits a wide range of Massey Ferguson tractors from the reliable 135 utility models through the big 690 row-crop machines. These tractors are workhorses on farms everywhere, powering everything from rotary cutters and hay equipment to manure spreaders and post hole diggers. The independent PTO system lets you run implements without engaging the transmission, making it essential for stationary work or when you need PTO power at different ground speeds.
Made to Last
Farm equipment seals face constant pressure cycles, temperature swings, and exposure to hydraulic fluid. This ring is built from quality rubber compounds that stay flexible and maintain their sealing properties through thousands of hours of operation. It’s designed to handle the demands of agricultural work while providing long-lasting, leak-free service.
Installation Notes
Installation is straightforward with basic tools and some mechanical know-how. Clean the sealing surfaces thoroughly before fitting the new ring—any dirt or old seal material will cause leaks. A light coat of hydraulic fluid on the seal helps with installation and prevents damage during assembly. Replace this ring whenever you’re servicing the IPTO unit to prevent future problems.
