Description

If you’ve been dealing with disc blades that don’t hold their spacing or hearing rattling from your harrow that wasn’t there last season, worn spring washers are probably to blame. This 7-inch diameter spring washer keeps your disc gang components properly loaded against each other, ensuring consistent cutting depth and smooth operation. When spring washers lose their tension, discs start moving around and you’ll end up with uneven tillage that shows up in next year’s crop.

What You’re Getting

Heavy-duty 65Mn spring steel construction that maintains tension season after season
7-inch diameter provides proper load distribution across the full disc assembly
3/8-inch thickness designed to handle the loads from bouncing through tough field conditions
Direct replacement that fits any disc harrow using 1-1/2 inch square axles

Built for Real Farm Work

This washer fits disc harrows running 1-1/2 inch square axles, which covers most mid-size to larger tillage equipment from brands like Case IH, John Deere, Krause, and others. Whether you’re chopping corn stalks in the fall, working up soybean ground, or preparing a clean seedbed for spring planting, this spring washer keeps everything tight and working like it should.

Made to Last

The 65Mn steel construction means high carbon and high manganese content—that’s the good stuff that gives this washer the spring memory to keep doing its job year after year. This isn’t cheap mild steel that’ll flatten out after a few seasons of heavy use. It’s built to handle the constant compression and release that comes with disc harrow work.

Good to Know

When you’re replacing spring washers, it’s worth checking the whole gang setup while you’ve got things apart. Look for worn spools, loose bearings, or damaged axles that might cause premature washer failure. Most operators replace spring washers in pairs to keep things balanced, and it’s smart to keep a spare or two in the shop—they’re the kind of part that usually fails when you’re in the middle of a time-sensitive operation.
