When you’re running a disc harrow and hear that grinding noise or feel a wobble that wasn’t there before, worn end washers are often the culprit. This 7-inch spring washer keeps disc blades properly positioned on their square axles and provides the controlled tension that prevents side-to-side play while still letting blades move freely during operation. Without good end washers, your discs can’t do their job of cutting residue and preparing seedbeds like they should.
What You’re Getting
- Hefty 7-inch diameter gives plenty of bearing surface to distribute load across the blade
- Beveled spring action maintains proper tension as wear occurs naturally over time
- Fits both 1-inch and 1-1/8-inch square axles commonly found on utility and farm disc harrows
- High-carbon, high-manganese spring steel construction handles the constant flex and stress
- 3/8-inch thickness provides the right amount of spring pressure without being too stiff
Built for Real Farm Work
This washer spring works on disc harrows with 1-1/8-inch square axles across many brands and models. Whether you’re working corn stubble, preparing bean ground, or breaking up compaction layers, disc harrows need proper blade spacing to cut and mix residue effectively. From small utility discs used for food plots to full-size tandem units covering serious acreage, this spring washer keeps everything aligned and working smoothly.
Made to Last
Farm equipment washers take a beating from dirt, moisture, and constant vibration. This spring washer is made from 65Mn steel—that’s high-carbon, high-manganese steel that’s specifically designed for spring applications. It flexes thousands of times without losing its tension and resists the kind of wear that makes cheaper washers go flat after a season or two.
Good to Know
When replacing end washers, it’s smart to do the whole gang at once since they usually wear at similar rates. Check your axle ends for burrs or damage that might tear up new washers prematurely. A light coat of grease on the washer contact points helps everything move smoothly and prevents rust from freezing things up during storage.
