The working speed of rotary tiller should be moderate, with a suitable speed of 2-3 kilometers per hour for dry fields and 5-7 kilometers per hour for already plowed or raked land. When cultivating in paddy fields, the speed can be increased appropriately, but it should not be too high to prevent the tractor from overloading and damaging the power output shaft.

Rotary tillers are mainly divided into three types according to the configuration of their rotary blade shafts: horizontal axis, vertical axis, and inclined axis. Among them, the horizontal rotary tiller is the most widely used due to its strong soil crushing ability. With one operation, the soil can be finely divided, the soil and fertilizer can be evenly mixed, and the ground can be leveled, meeting the requirements for sowing in dry land or planting in paddy fields. However, the horizontal rotary tiller has poor coverage ability for residues and weeds, shallow tillage depth (12-16 cm for dry tillage and 14-18 cm for water tillage), and high energy consumption.
