Abstract
Disclosed is a repairing rack for a mower. The repairing rack includes an underframe, a hydraulic pump, double lifting cantilevers and mower brackets. Roller wheels are installed at the bottom part of the underframe and double vertical columns are fixed at the upper part of the underframe and a cross bar is fixed between the two vertical columns. A handle is installed on the cross rod. Each vertical column and the lifting cantilevers hinged at the upper ends of the vertical columns are combined so that double parallel four-bar mechanisms are formed. One end of one lifting cantilever and one end of the other lifting cantilever, far away from the vertical columns, are installed on the same beam together. The mower brackets are fixed at the two ends of the beam. The bottom part of the hydraulic pump is hinged on the underframe corresponding to the inner sides of the double vertical columns. A piston push rod of the hydraulic pump is hinged on the lifting cantilevers. An oil inlet pedal and an oil outlet pedal of the hydraulic pump are both arranged at the inner sides of the double vertical columns. The beneficial effects of the repairing rack for the mower are that: 1) the double-vertical-column structure enables the mower brackets to ascend and descend stably; 2) a fan-shaped toggle plate plays a self-locking role; 3) the mower brackets are adjustable in distance so that the mower brackets are applicable to mowers of different models.
