Description
When it’s time to replace the blades on your rotary cutter, you’ll want to pay close attention to the blade bolts too. These hardworking fasteners take a beating from the constant vibration and forces of cutting, and a worn or damaged bolt can mean a blade coming loose in the field—something nobody wants to deal with when there’s work to get done.
What You’re Getting
- Heavy-duty 1″ diameter bolt with left hand threads that stay tight during operation
- Generous 1-3/8″ shoulder diameter spreads the load evenly across the blade
- Engineered specifically for the high-stress environment of rotary cutting
- Made in the USA with quality materials that handle the punishment
Built for Real Farm Work
This bolt fits a wide range of Servis rotary cutters including the Cyclone, Flex, and Gyro series in various cutting widths. Whether you’re running a compact 60-inch cutter behind your utility tractor or managing pastures with a larger 160-inch model, these are the cutters you see maintaining fence rows, clearing brush, and keeping food plots tidy across farm country.
Made to Last
The left hand thread design is no accident—as the blade spins clockwise during operation, the rotation actually helps tighten the bolt rather than loosen it. This self-tightening action, combined with robust construction, keeps your blades secure season after season even through the worst conditions.
Installation Notes
Remember, left hand threads turn opposite of what you’re used to—lefty tighty, righty loosey. Make sure to torque the blade bolt to specification and check that the shoulder sits flush against the blade. If you’re replacing bolts, now’s a good time to replace blades as a complete set to maintain proper balance.
