1. The rotary cultivator is overloaded. Cause: Overworking, heavy soil, or overly hard ground conditions. Solution: Reduce the depth of plowing and adjust the forward speed as well as the coulter speed to prevent excessive strain on the machine.
2. The rotavator jumps while in operation. Cause: Hard soil or incorrect blade installation. Solution: Lower the unit’s forward speed and the coulter speed, and ensure that the blades are properly installed for optimal performance.
3. Large clods are thrown intermittently by the rotary cultivator. Cause: Bent, broken, missing, or excessively worn blades. Solution: Straighten or replace the damaged blades to ensure smooth and even soil breaking.
4. The ground remains uneven after working. Cause: Mismatch between the unit’s forward speed and the spindle speed. Solution: Adjust the speeds appropriately to achieve a more uniform tilling result.
5. The coulter gearbox makes unusual noise. Cause: Foreign objects got lodged during installation, or damage occurred to gears and bearings. Solution: Remove any foreign objects, and replace damaged bearings or gears if necessary.
6. The rotary cultivator produces metallic knocking sounds. Cause: A loose drive chain collides with the transmission housing; deformed blades, left arms, or coulter shafts hit each other; or loose blade fixing screws. Solution: Check and adjust the tension of the drive chain, repair or replace deformed parts, and tighten any loose screws.
7. The coulter shaft of the rotary cultivator does not rotate. Cause: Stuck gears or bearings, deformation of the left arm or coulter shaft, broken drive chain, or the shaft being clogged with mud. Solution: Correct or replace severely deformed or damaged components, clean the coulter shaft from mud, and ensure proper functioning of the drive system.
These common issues can significantly affect the efficiency and performance of your rotary cultivator. Regular maintenance, proper blade alignment, and timely adjustments are essential to keep the machine running smoothly and extend its lifespan. Always refer to the manufacturer's guidelines for specific troubleshooting steps and safety precautions.
