Description

That clunking noise from your PTO shaft isn’t something to ignore—it’s your U-joint telling you it’s time for a replacement before it leaves you stranded with a broken driveline. When you’re powering a rotary cutter through thick pasture grass or running a round baler during hay season, the last thing you need is a failed universal joint bringing everything to a halt.

What You’re Getting

Heavy-duty 27mm cup diameter that handles the high torque loads your PTO puts out
74.6mm height designed specifically for MF 300 and 3000 series driveline specifications
Precision manufacturing that eliminates play and vibration for smooth power transfer
Quality needle bearings inside that reduce friction and extend service life
Direct replacement design—no modifications or special tools needed

Built for Real Farm Work

This U-joint fits your Massey Ferguson 375, 390, or 3050 series tractor perfectly, handling the constant angle changes as your implements follow ground contours. Whether you’re running heavy equipment like rotary cutters and balers or operating tillers for seedbed preparation, these joints transfer serious power while dealing with the punishing conditions of agricultural PTO use.

Made to Last

The 27mm cups provide plenty of bearing surface for long life under load, while quality needle bearings maintain tight tolerances that prevent the slop that destroys entire drivelines. When you’re depending on PTO power for critical operations like hay making or field prep, a quality U-joint is cheap insurance against costly downtime.

Installation Notes

Always replace U-joints in pairs on the same shaft for balanced operation. Remove circlips carefully—they love to fly off and disappear in tall grass. Use a proper U-joint press or carefully work with a vise and appropriate sockets. Pack with quality grease before assembly and check for smooth operation through the full range of motion. Most folks complete the job in 30-45 minutes per joint.
