Baler Shear Bolts — Protect Your Baler’s Drive System
Shear bolts are your baler’s first line of defense against costly drive system damage. Engineered to fail at a precise load, they protect the flywheel, PTO shaft, gearbox, and plunger drive from shock loads caused by rocks, wire, or overfeeding — sacrificing an inexpensive bolt to save an expensive drivetrain component.
Quality Farm Supply stocks aftermarket baler shear bolts and shear bolt kits compatible with leading brands of square and round balers — including John Deere, Case IH, New Holland, Hesston, Massey Ferguson, Kuhn, Vermeer, and many others.
Always keep a supply of shear bolts on hand during baling season — when one shears in the field, you need the right replacement immediately to get back to work. Key points:
- Always use the correct grade and size — substituting a stronger bolt defeats the purpose and can cause serious drivetrain damage
- Replace in matched sets where required — some balers use multiple shear bolts that must be replaced together to maintain balanced load protection
- Shear bolt kits — convenient multi-pack quantities to keep you running through the season
Quality Farm Supply has the baler shear bolts you need, in stock and ready to ship — “The Go-To Source” for baler parts and hay tool components.
