A disc harrow is an agricultural implement used to till the soil where crops are to be planted. It is typically used after a field has been plowed and before it is planted. Here are some key details about disc harrows:
Design and Components:
1. Discs: The primary component of a disc harrow are the concave discs, which are arranged in gangs. These discs cut and lift the soil.
2. Gangs: Discs are mounted on a frame in groups known as gangs. The gangs can be angled to increase the aggressiveness of the tilling.
3. Frame: The frame holds the discs and gangs together and is usually made of heavy-duty steel to withstand the stresses of tilling.
4. Hitch: This is used to attach the disc harrow to a tractor. It can be a three-point hitch or a pull-type hitch.
The heavy-duty disc harrow main features are wide space operation, harrow space transportation, reliable structure with specially-used rolling bearing, easy maintenance, high productivity.
