Tractor Yoke Ball Shear for 5 Series PTO Drivelines with 1-3/8 Inch 21 Spline Connection

Description

When your PTO shaft starts making that ominous clicking noise or you’re constantly dealing with broken shear pins, it’s time to upgrade to a ball shear system that’s built for reliability. That clicking, popping PTO shaft isn’t going to fix itself, and ignoring worn U-joints is a recipe for catastrophic failure that can destroy implements, damage tractors, or worse. This Weasler ball shear tractor yoke eliminates the hassle of constantly replacing pins while giving you consistent overload protection that actually works when you need it most.

What You’re Getting

• Ball shear design that’s more reliable than traditional shear pins under real farm conditions
• 5 series construction sized right for mid-range tractors and implements
• 1-3/8 inch 21 spline connection that fits common PTO shaft specifications
• Consistent breakaway torque that protects your drivetrain from damage
• Field-replaceable components when overload protection does activate

Built for Real Farm Work

This Series 6 yoke is right at home on implements like smaller rotary cutters, tedders, rakes, and other PTO equipment that doesn’t need the beef of a Series 7 or 8. It’s perfect for those 40-80 horsepower tractors running lighter implements where you need reliable overload protection without the constant maintenance headaches. The 5 series size bridges the gap between lighter utility work and heavier field operations, making it ideal for farms running a variety of implements.

Made to Last

Weasler builds these components knowing that PTO failure isn’t just inconvenient—it’s dangerous. Weasler builds this tubing to handle the constant torque loads and vibration that come with farm work. The steel construction resists fatigue cracking and maintains its shape under load. The ball shear mechanism is engineered to activate consistently at the designed torque level, protecting your expensive equipment while minimizing downtime.

Good to Know

Ball shear yokes require proper torque settings to function correctly – too tight and they won’t protect, too loose and they’ll trip unnecessarily. Mark your yoke positions before disassembly to maintain proper phasing and prevent vibration. Clean those yoke bores thoroughly before installation, and don’t forget to grease the fittings after assembly to get the best performance from your driveline system.
