Description
When your disc blades start wandering all over the place or bunching up on one end of the gang, chances are your spools are worn out. These 4-inch spools keep your disc blades properly spaced and aligned so they cut evenly across the width of your harrow instead of leaving streaks and unworked strips in the field.
What You’re Getting
- Precision 4-inch width maintains proper blade spacing for even cutting
- Works with both 7-1/2 inch and 9-inch disc spacing setups
- Built for 1-1/2 inch round axles – slides on smooth and stays put
- Heavy-duty construction that handles the constant vibration and impacts of field work
Built for Real Farm Work
This spool fits a wide range of Case IH disc harrows including the 132, 340, 350, 370, 470, 475, 480, 485, 490, 496, 3800, 3850, 3900, and 3950 models. Whether you’re using a smaller offset disc for corn stalks or running a big tandem disc for primary tillage, proper gang spacing makes all the difference in getting uniform residue chopping and soil mixing.
Made to Last
Disc harrow spools take a beating from rocks, debris, and the constant stress of keeping heavy blades in line. This replacement is built with the same specs and materials as the original factory part, so it’ll hold up to years of spring and fall fieldwork without wearing out prematurely.
Good to Know
Check your spool spacing while gangs are apart – it’s easier to get everything right when you can see what you’re doing. This spool replaces OEM part 101191C1, making it a direct swap with no modifications needed. A quick tip: when rebuilding disc gangs, replace all the spools at once rather than mixing old and new – it keeps everything running smooth and balanced.
