Description
If your rotary cutter blade is loose or you’ve noticed vibration while mowing, there’s a good chance your blade bolt is worn or the nut has backed off. A loose blade is dangerous and tears up your cutter deck fast—plus it makes for a rough ride. This complete bolt kit gets everything back tight and safe so you can get back to cutting grass and brush with confidence.
What You’re Getting
- Complete kit includes heavy-duty 1-inch bolt, grade 8 nut, and lock washer—no hunting for parts
- Precision-machined bolt threads hold tight under the vibration and shock of cutting thick brush
- Proper 4-1/8 inch overall length provides the right amount of thread engagement without bottoming out
- Made in the USA with quality materials that won’t let you down when you need them most
Built for Real Farm Work
This kit fits Bush Hog Regular Duty models, Terrain King TK60 Series, CP180 and X3 cutters, along with Marvel 4, 5, 6, and 7-foot units and Hico Standard 4, 5, and 6-foot models. These are the workhorses you see cutting pastures, maintaining fence rows, and keeping farm roads clear. Whether you’re running a compact tractor with a 5-footer or pulling a bigger cutter behind your utility tractor, this bolt kit handles the job.
Made to Last
Blade bolts take a beating from rocks, stumps, and the constant shock of cutting. This kit uses a proper 1-inch diameter bolt with 14 threads per inch—the right size to handle the forces without stretching or breaking. Always torque the blade bolt to specification and check for any play in the center hole before putting the cutter back to work.
Good to Know
Installation is straightforward—just make sure you clean the threads on the spindle before installing the new bolt. A little anti-seize compound on the threads makes future removal easier. Always replace blades as a complete set to maintain proper balance—mismatched blades cause vibration that’s hard on your tractor and spindles. Keep a spare kit in the toolbox since blade bolts have a way of disappearing when you need them most.
