Description
When your disc harrow isn’t cutting evenly or you’ve got discs binding up on the gang, sometimes all you need is a simple shim to get the spacing just right. This .187-inch thick spacer fits snugly on your 1-1/2 inch square axle and helps keep everything properly aligned so your discs can do their job without fighting each other.
What You’re Getting
- Precision .187-inch thickness for exact spacing requirements
- Made for 1-1/2 inch square axles that Case IH uses on their disc harrows
- Heavy-duty construction that won’t compress or distort under load
- Direct replacement that slides right onto your existing gang axle
Built for Real Farm Work
This shim works on Case IH disc harrows including the 501, 596, and 770 models, plus the RMX790 series. These are workhorses that see everything from spring tillage to fall residue management, cutting through corn stalks and incorporating crop residue to prep your seedbed for next season.
Made to Last
Disc harrow components take a beating from rocks, roots, and heavy soil loads. This spacer is built to handle those forces without bending or wearing out, keeping your disc spacing consistent season after season. The square bore design matches your axle perfectly for a secure fit that won’t slip or rotate.
Good to Know
Installation is straightforward – slide it onto the axle where you need the spacing adjustment. If you’re rebuilding a gang, it’s smart to inspect all your spacers and replace any that show wear or damage. A good tip is to keep a few extras on hand since proper spacing is critical for even disc wear and optimal soil preparation.
