Description
When you’re working on your Case IH disc harrow and notice wobbling discs or uneven spacing, there’s a good chance the gang spools need attention. These 3-inch spools are what keep everything properly aligned on the square axle, maintaining that critical 9-inch spacing between discs. Without good spools, your discs won’t cut evenly and you’ll end up with ridges in your field instead of smooth soil preparation.
What You’re Getting
- Machined bearing surface for smooth disc operation and reduced wear
- Proper 3-inch width maintains correct disc spacing for even soil preparation
- 1-1/8 inch square bore fits standard Case IH axles without modification
- Durable construction stands up to field debris, rocks, and constant rotation
Built for Real Farm Work
This spool works on a wide range of Case IH disc harrows including models 37, 46, 48, 60, 61, 76, 120, 122, 130, 132, 150, 330, 350, 370, 470, 480, 490, 610, and 760 with 9-inch spacing. These are the harrows you rely on for seedbed preparation, residue management, and breaking up compacted soil layers before planting season.
Made to Last
The machined bearing surface on this spool reduces friction and heat buildup while the discs are spinning. That smooth operation means less wear on both the spool and the disc hub, extending the life of your entire gang assembly. It’s built to handle the constant rotation and side loads that come with working through tough soil conditions.
Good to Know
Installation is straightforward—slide the old spool off the square axle and replace with the new one. While you’ve got the gang apart, it’s a good time to check disc condition and bearing wear. If one spool was worn out, the others on that gang are probably due for replacement too.
