[0076] The working principle of the utility model is as follows:

[0077] The power source acts on the rear pull rod to make the rear pull rod move, the rear pull rod transmits force to the left rocker arm through the pin shaft to make the left rocker arm rotate around the connecting shaft, the connecting shaft transmits force to the right rocker arm through the spline, and the left and right rocker arms rotate simultaneously to finally lift the mower tool.

[0078] The advantages of the lifting mechanism are as follows:

[0079] 1. The left and right rocker arms are connected in the spline cooperation form, the left and right lifting heights are synchronized, and installation and disassembly are convenient.

[0080] 2. Reinforcing ribs are welded at weak positions to greatly improve the overall strength.

[0081] 3. The rear pull rod connecting block is optimized, the weight is reduced, and processing and cost saving are facilitated.

[0082] Compared with the coiled pin limiting, the spline cooperation has almost no elastic torsion when stressed, the transmission precision is high, the elastic check ring is more convenient to install, reinforcing ribs are added at weak positions, the structural short board is compensated with the least cost to greatly improve the overall structure, the new rear pull rod connecting block has simple structure and light weight, meanwhile, sufficient connecting interfaces and connecting strength are reserved, and cost is saved.

[0083] However, the traditional mower lifting mechanism has the following problems:

[0084] 1. The previous mower lifting left rocker arm structure has obvious weak positions and is prone to deformation during movement.

[0085] 2. The left and right rocker arms are limited by the coiled pin, the structure torsional stiffness is poor, elastic torsional deformation is prone to occur during lifting, the left and right lifting of the mower is inconsistent, tilting phenomenon occurs, the coiled pin needs to be knocked in / out from one side in the limited space during installation / disassembly, and the operation is inconvenient and time-consuming.

[0086] 3. The rear tie rod weld structure is overly redundant.

[0087] It is apparent that a person skilled in the art can make many modifications to the application described herewithout, without departing from the scope of the application.
