Description

You’re in the middle of a tough day running a front loader, and your foot throttle starts acting up—either it won’t return to idle when you lift your foot, or the pedal feels mushy and unresponsive. A worn return spring can leave your engine racing when you need it to idle, making precise work nearly impossible and wasting fuel while you fight to control engine speed.

What You’re Getting

Strong enough to reliably return the engine to idle but not so stiff that your leg gets tired during long work sessions
Durable spring steel construction that maintains proper tension through thousands of cycles
Direct replacement that restores factory-intended throttle response and control
Prevents engine from racing when foot pressure is removed from the pedal

Built for Real Farm Work

This spring fits your Massey Ferguson 600 series tractors (675, 690, 698, 698T, 699, 670) and 1000 series models (1004, 1004T). These are the workhorses you depend on for everything from loader work and cultivation to hay production and transport—jobs where precise throttle control makes all the difference between smooth operation and frustrating struggles.

Made to Last

This spring uses high-quality spring steel that won’t lose tension from heat cycles or age. The precise specifications ensure it provides the right amount of return force to bring your throttle back to idle position reliably, season after season, without making the pedal too heavy to operate comfortably.

Installation Notes

This is a straightforward replacement that typically takes just a few minutes once you access the foot throttle mechanism. The precise bend angles ensure positive return force without making the lever too stiff to operate. While you’ve got things apart, it’s a good time to check your throttle cable for any binding or fraying that might be causing problems.
