Description

When your rotary cutter’s tail wheel starts wobbling or making noise, it’s usually the hub that’s worn out. This cast iron hub gets your cutter rolling smoothly again, with oil-impregnated bushings that keep everything lubricated and running quiet. For old-style Bush Hog rotary cutters using two tapered roller bearings.

What You’re Getting

Heavy-duty cast iron construction that handles the constant bouncing and impacts of mowing
Two oil-impregnated bushings with 25.15mm ID that stay lubricated without constant greasing
4-bolt mounting pattern that fits most standard rotary cutter tail wheel setups
Direct replacement for Bush Hog part 50074520 tail wheel assembly

Built for Real Farm Work

This hub works on a wide range of rotary cutters, especially the older Bush Hog models that use the traditional bearing setup. Whether you’re mowing pastures, cutting weeds along fence rows, or cleaning up overgrown fields, this hub keeps your tail wheel tracking straight and supporting the deck properly.

Made to Last

Cast iron might seem old-fashioned, but it’s still the best material for rotary cutter hubs. It dampens vibration, resists cracking from impact, and the oil-impregnated bushings mean less maintenance than traditional grease fittings that always seem to get plugged with dirt and debris.

Installation Notes

This is a direct bolt-on replacement that uses your existing wheel and hardware. The bushings come pre-installed, so you’re ready to mount and go. Just make sure to check your spindle for wear while you’ve got the old hub off—a worn spindle will eat up a new hub quickly.
