Description
When you’re rebuilding a disc gang or replacing worn components, getting the right spacing between your disc blades is crucial for proper field performance. This 7-1/2 inch spool keeps your discs properly positioned on the axle, so they cut evenly through residue instead of clustering together or leaving uncut strips.
What You’re Getting
- Durable ductile iron construction that won’t crack under field stress
- Full 7-1/2 inch length provides proper spacing for optimal disc performance
- 1-1/2 inch round bore fits standard Case IH disc axles perfectly
- Direct replacement for original equipment – no modifications needed
Built for Real Farm Work
This spool fits Case IH disc harrows including the 330, 340, 350, 370, 470, 475, 480, 485, 490, and 496 models, along with many others in the 3800 and 3900 series. These are the workhorses that handle everything from corn stalk residue to preparing seedbeds for spring planting. Whether you’re running a tandem disc or an offset model, proper spacing makes the difference between a smooth finish and ridges that show up in your crop.
Made to Last
Ductile iron construction handles the constant vibration and impact loads that come with disc harrow work. Unlike cast iron that can crack when you hit rocks or roots, ductile iron flexes slightly and bounces back. This material choice means the spool will keep doing its job season after season, even when conditions get tough.
Good to Know
When you’re replacing spools, it’s smart to check the whole gang assembly while you’ve got things apart. Look for worn bearings, cracked housings, or bent axles that could cause problems down the road. The proper spacing this spool provides only works if everything else in the gang is in good shape too.
