Description
When you’re running a rotary cutter with stump jumpers, having the right hub makes all the difference between smooth cutting and constant headaches. This 12 spline hub connects your blades to the gearbox output shaft, transferring all that power while handling the impact when your blades hit rocks, stumps, or uneven ground. It’s the critical link that keeps your cutting system running strong even when the terrain gets rough.
What You’re Getting
- Tapered spline design that locks securely onto the gearbox shaft and won’t loosen during operation
- 12 spline configuration provides plenty of contact area for solid power transfer without slippage
- Engineered specifically for stump jumper setups where blades need to flex and absorb impacts
- Precision machined dimensions ensure proper fit and balance on your cutting system
- Heavy-duty construction that handles the shock loads from hitting obstacles
Built for Stump Jumper Applications
This hub is designed to work specifically with certain gearboxes that power rotary cutters equipped with stump jumpers—those spring-loaded blade assemblies that let your cutter ride over obstacles instead of getting hung up. Whether you’re clearing brush lots, maintaining rough pastures, or cutting around fence lines where stumps and rocks are just part of the landscape, this hub keeps your blades spinning and your work moving forward.
Made to Last
Rotary cutter hubs take tremendous punishment from constant spinning, impact loads, and exposure to dirt and moisture. This one’s built from quality steel that resists wear and deformation even when your blades are pounding through heavy brush or bouncing off obstacles. The tapered splines distribute stress evenly and maintain their grip season after season.
Installation Notes
This hub slides right onto the gearbox output shaft—the tapered splines ensure it seats properly and stays put. Make sure the shaft is clean and free of burrs before installation, and check that the hub seats fully against the shoulder. A quick tip: a light coat of anti-seize on the splines makes future removal much easier when it’s time for maintenance.
