What Horsepower is Suitable for a 2-Meter Rotary Tiller?
2 Answers
A 2-meter rotary tiller requires a power output of more than 80 horsepower. Selection of Rotary Tillers: Tractors with different horsepower need to be matched with rotary tillers of corresponding working widths. If the rotary tiller is too large, the tractor may not be able to pull it effectively. Conversely, if the rotary tiller is too small, it will waste fuel and cause the tractor tires to compact the soil. The power output speed of the tractor and the blade shaft speed of the rotary tiller should be proportional. Generally, the blade shaft speed of a rotary tiller is 220-280 RPM. Speeds that are too high or too low will affect the tillage quality. Usage Precautions: The angle between the power input shaft of the rotary tiller, the universal joint, and the power output shaft of the tractor should be kept within 15 degrees. During operation, the rotary tiller should not be lifted too high, as this may cause the tractor's power output shaft to break. When turning in the field, always disengage the power output shaft of the rotary tiller before lifting it to turn. Never attempt to turn while the rotary tiller is engaged, as this can lead to breakage of the power output shaft and damage to the suspension mechanism.
I've been farming for decades and have used many rotary tillers. For a two-meter-wide rotary tiller, 20 to 30 horsepower is sufficient for medium soils like loose loam or sandy ground. But if you encounter clay or hard soil, you'll need at least 35 horsepower; otherwise, the tractor won't handle it and the equipment will wear out. Last year, I tried a 25-horsepower model on a new field, but the tilling depth was insufficient, and the yield dropped by half. Now, I recommend opting for a standard 30-horsepower model—it's both economical and efficient. Also, consider the tractor model; a medium-sized diesel engine will do. Remember to regularly maintain the bearings and blades to reduce extra load. In short, my field experience tells me to start with at least 25 horsepower to adapt to different terrains. When choosing horsepower, don't skimp—too low can easily burn out the engine.
