Description

That loose, sloppy hand throttle that won’t hold position when you’re trying to run PTO equipment at steady RPM isn’t just annoying—it can ruin your work quality and waste fuel. Hand throttle control is essential for maintaining consistent engine speeds during PTO operations like mowing, baling, or running generators. This upper washer is a small but critical part that provides the proper tension to keep your throttle lever exactly where you set it.

What You’re Getting

Precision-sized washer that restores proper throttle lever tension
Direct replacement that fits original mounting points perfectly
Quality materials that resist wear from constant throttle adjustment
The right thickness to eliminate play without binding the controls

Built for Real Farm Work

This washer fits Massey Ferguson 100 series tractors (135, 165, 168, 178, 188) and 200 series models (240, 290). Whether you’re running a rotary cutter that needs steady 540 PTO speed, operating a baler where consistent engine RPM affects bale density, or powering a generator where speed variations cause problems, proper hand throttle control makes all the difference in work quality.

Made to Last

Farm equipment controls take constant use and abuse from operator adjustments throughout long working days. This washer is made from materials that provide consistent friction without compressing or wearing out quickly, unlike makeshift repairs with random washers that either don’t hold or bind up the mechanism.

Good to Know

Installation is straightforward—just disassemble the throttle lever assembly, replace the old washer, and reassemble. While you’re in there, check the entire throttle mechanism for wear and lubricate pivot points. Unlike makeshift repairs with washers or other substitutes, this proper part maintains the right amount of resistance for smooth adjustment while preventing unwanted movement.
