If you’ve been wrestling with worn or stripped blade bolts on your John Deere rotary cutter, you know how frustrating it is when the blade won’t stay tight. A loose blade doesn’t cut worth a darn, and it’ll shake your tractor apart to boot. This heavy-duty replacement bolt gets your blade locked down solid so you can get back to making clean cuts through thick brush and heavy grass.
What You’re Getting
- 1-inch diameter with 14-thread right-hand pattern for maximum holding power
- Grade 8 strength steel that won’t stretch or fail under load
- Precision machining ensures perfect fit with John Deere spindle assemblies
- Works with the 165228 hex nut to create a secure blade mounting system
Built for Real Farm Work
This bolt fits a wide range of John Deere rotary cutters including the popular MX, HX, CX, and LX series models, plus the 4, 5, 403, 506, 516, 606, 613, 616, 717, and 1517 series. Whether you’re maintaining fence lines, clearing pastures, or cutting roadside ditches, these cutters see serious action and need hardware that can handle the stress.
Made to Last
Blade bolts take a beating from the constant shock and vibration of cutting operations. This one’s built from high-strength steel that resists fatigue cracking and thread wear. The coarse 14-thread pitch provides excellent grip while making removal easier when blade replacement time comes around.
Good to Know
Always use the proper torque specification when installing—too loose and the blade comes off, too tight and you’ll strip the threads. Make sure to pair this bolt with the correct nut (part 165228) for optimal performance. If your old bolt is really stuck, some penetrating oil and patience work better than brute force.
