Rotavators and rotary tillers operate under high rotational speeds, with each blade striking compacted earth hundreds of times every minute. If blade geometry or heat treatment is substandard, farmers suffer premature wear, unbalanced rotor vibration, and excessive diesel consumption.
Drop Forging vs. Stamped Blades
Unlike inexpensive stamped blades whose grain flow is severed at the edge, hot drop-forged tiller blades retain uninterrupted metallurgical grain orientation around the critical elbow and mounting shank. This structural alignment eliminates fatigue cracking under continuous rock contact.
Inspection & Maintenance Best Practices
Check blade sharpness and mounting torque every 50 hours of operation. Always replace worn blades in matched pairs across the rotor to maintain dynamic rotational balance and prevent gearbox seal damage.
