Description

When you’re cutting hay or silage and hear that dreaded squeal from your disc mower’s drive system, you know it’s time for new belts. A slipping or cracked drive belt doesn’t just slow down your cutting discs—it puts extra strain on your tractor’s PTO and can leave you with uneven stubble or completely uncut strips. This set of four replacement drive belts gets your Kuhn GMD800 back to making clean, efficient cuts across the full width.

What You’re Getting

Complete set of four belts—everything you need to service your mower at once
Each belt measures 118.06 inches long by 5/8 inch wide for perfect fit
D&D Global construction that holds up to the constant flexing and high speeds of disc mower operation
Designed to handle the power transfer needed for clean cutting in thick or tough crop conditions

Built for Heavy-Duty Mowing

These belts are engineered for the demanding work your Kuhn GMD800 series does every day. Whether you’re cutting first-cut alfalfa that’s gotten away from you, tackling thick grass hay, or chopping corn stalks for silage, these drive belts transfer power reliably from your mower’s gearbox to each cutting disc. They’re also compatible with John Deere 285 disc mowers that share similar drive configurations.

Made to Last

Disc mower belts take a beating from constant starts, stops, and the shock loads that come with hitting rocks or heavy crop material. These belts use materials and construction designed to resist stretching, cracking, and the heat buildup that comes from high-speed operation. They maintain proper tension longer than cheaper alternatives.

Good to Know

Replace all four belts at the same time—mixing old and new belts creates uneven loading that can cause premature failure. Check your pulleys for wear and proper alignment while you’ve got the belts off. Keep your spare set handy during hay season, because there’s never a good time for belt failure when the weather window is closing.
