Description
When you’re changing blades on your Servis rotary cutter, having the right nut makes all the difference. This 3/4-inch left hand thread lock nut pairs with the 165235 blade bolt to keep your cutting blades secure, even when they’re spinning at high speeds through thick brush and weeds.
What You’re Getting
- 3/4-inch left hand thread design that works specifically with Servis blade bolts
- Lock nut construction prevents loosening from vibration and rotation forces
- Reliable AgSmart quality that holds up to the demands of rotary cutting
- Direct replacement for worn or damaged blade nuts
Built for Real Farm Work
This nut works with the Servis and Schulte rotary cutter blade bolt that secures your cutting blades to the spindle. Whether you’re brush-hogging pastures, maintaining fence rows, or clearing overgrown areas, proper blade attachment is critical for safe operation and effective cutting.
Made to Last
Farm equipment takes a beating, and rotary cutter hardware has to handle some of the toughest conditions. This lock nut is built to resist the constant vibration and high-speed rotation that would work a regular nut loose. The left hand thread design actually tightens under the rotational forces of normal operation.
Installation Notes
Remember that left hand threads turn counterclockwise to tighten—the opposite of what you’re used to. Torque blade bolts to specification – too loose risks blade loss, too tight can crack the blade. Always replace blade hardware as a set and check that everything’s snug before heading to the field.
