Description

When your PTO won’t engage smoothly or you’re seeing hydraulic fluid around the rear PTO housing, it’s often a worn O-ring that’s letting you down. This small but critical seal keeps your PTO clutch system working properly—no leaks, no slippage, just reliable power transfer when you need it most. A few minutes with this replacement O-ring can save you from bigger problems down the road.

What You’re Getting

Precise fit for John Deere rear PTO clutch systems
High-quality rubber compound that handles hydraulic fluid and temperature swings
OEM-specification seal that maintains proper clutch pressure
Direct replacement—no modifications or special tools needed

Built for Real Farm Work

This O-ring fits a wide range of John Deere’s most popular tractors, from the versatile 6000 series utilities to the modern 6R and 7R row-crop machines. Whether you’re running a round baler with a 6420, operating a brush hog with a 6155M, or pulling a grain cart with a 7230R, this seal keeps your PTO clutch system operating at full pressure for smooth engagement and reliable power transfer.

Made to Last

PTO clutch O-rings work in a tough environment—constant hydraulic pressure, vibration, and heat cycling from hours of operation. This seal uses material that’s specifically formulated to resist hydraulic fluid breakdown and maintain its elasticity through thousands of PTO cycles. It won’t harden up or crack like cheaper alternatives that leave you stranded during critical work periods.

Installation Notes

This is a straightforward replacement that most folks can handle with basic tools and some hydraulic system knowledge. Make sure to drain the hydraulic fluid from the PTO housing before starting, and clean the seal groove thoroughly. A thin coat of hydraulic fluid on the new O-ring helps it seat properly without pinching.
