As the sales and usage season for rotary cultivators approaches, it's essential to understand how to choose and use these agricultural tools properly. Based on past issues and user experiences, there are four major hidden dangers associated with rotary cultivator products: first, inadequate safety protection; second, unqualified blade hardness; third, poor appearance quality; and fourth, non-standard product labeling. To help farmers make informed decisions, here are key points to consider when purchasing and using a rotary cultivator.
**Purchase Tips:**
◠Ensure proper support. The power consumption of the rotary cultivator should be lower than the output power of the tractor it is used with. The working width should match the tractor’s wheelbase, and when mounted on a three-point linkage, it should not affect the weight distribution of the tractor’s front and rear wheels.
◠Prioritize safety. The rotating parts must have a sturdy safety guard, and the machine should be stable when placed on its own without tipping over. A clear warning sign and comprehensive user manual—including technical specs, safety instructions, assembly guides, maintenance tips, and troubleshooting—are essential.
â— Choose a model that meets local farming needs, such as a minimum tilling depth of 10 cm.
â— Look for reliable after-sales service, including maintenance and spare parts availability. Always ask for a "Three Guarantees" service card (repair, replacement, and return) and ensure the seller complies with agricultural machinery regulations.
◠Prefer models that have received the Ministry of Agriculture’s promotion permit and bear the corresponding certification.
**Usage Precautions:**
Rotary cultivators operate at high speeds, so safety is crucial. Before starting, check all components, especially the blades and their fixing bolts. Make sure the clutch is disengaged before starting the tractor. Only engage the power once the machine has reached the correct speed and is slowly lowered into the soil. Avoid sudden drops or reversing once in the field.
When turning or moving between fields, keep the machine raised but not too high, and reduce engine speed if necessary. Never allow people or animals near the rotating parts, and always turn off the power before inspecting or replacing blades. Start at a slow speed (2–3 km/h) for the first pass and increase to 5–7 km/h for previously tilled land to avoid overloading the PTO shaft.
Ensure the tractor wheels move on uncultivated areas to prevent soil compaction. Adjust the wheel spacing to stay within the working range of the cultivator. Clean any grass wrapped around the blades regularly to avoid excessive load. Never carry passengers while operating the machine.
**Maintenance Guidelines:**
Regular maintenance is key to extending the life of your rotary cultivator. After each use, check and tighten bolts, inspect pins and split pins, and lubricate the gearbox and bearings. At the end of each season, perform a thorough cleaning, replace oils, check blade wear, and inspect hoods and frames for damage. If the machine is not in use for a long time, store it on a level surface and avoid hanging it from the tractor.
By following these guidelines, you can ensure safe, efficient, and long-lasting performance from your rotary cultivator.
