Detailed Description

The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed. Referring to fig. 1, a mower deck 101 is provided with a power plant mounting bracket 102. The mower base plate 101 is provided with a hinge shaft mounting hole 103 of the swing arm 301. A power plant output shaft hole 104 is provided for the power plant output shaft on the power plant mounting bracket 102. The shaft center line of the hinge shaft mounting hole 103 coincides with the shaft center line of the power unit output shaft hole 104.

Referring to fig. 2, the axis of the hinge shaft 201 is provided with a through hole 202, and the top end of the hinge shaft 201 is provided with a flange surface 203.

The swing arm 301 is hinged to the hinge shaft mounting hole 103 of the mower base 101, and the swing arm 301 is pressed by the flange surface 203 from above.

A pulley 302 and a dodge mower deck 303 are mounted to the other end of swing arm 301.

Referring to FIG. 3, the power unit mounting bracket 103 has a power unit gear box 401 mounted thereon.

The axial center line of the output shaft 402 extending downward from the gear case 401 coincides with the axial center line of the hinge shaft 201.

A belt pulley 403 is arranged on an output shaft 402 of the gear box 401, the middle part of the output shaft 402 passes through the through hole 202 of the hinge shaft 201, and a mower disc 404 is arranged at the tail end of the output shaft 402.

The hinge shaft 201 is threaded below the mower deck 101, and the mounting nut 204 fixes the hinge shaft 201 to the mower deck 101 and presses the swing arm 301.

The pulley 403 and the pulley 302 are driven by a V-belt 405.

Referring to fig. 4, the input of the gearbox 401 is connected to the output of the mower transfer gearbox 502 via a universal joint drive assembly 501. The input end of the transfer gearbox 502 is connected with a power output device such as a tractor.
