Product Description
Equipment Application
The power harrow is mainly used in agricultural tillage for seedbed preparation and secondary tillage before sowing. After replacing the components, it can also be used for straw crushing and returning to the field, making it a multi-functional agricultural implement.
Working Principle
This implement utilizes the rear PTO shaft of the tractor to transmit power and motion to the in-line arranged rake tooth support discs through a gear mechanism. Two vertically downward rake teeth are fixed on each support disc, and the rotation of the rake teeth completes the tillage operation.
