When the mower moves, the left side driving wheel support 3 and the right side driving wheel support 4 can swing up and down along with the terrain because the left side driving wheel support and the right side driving wheel support are respectively rotatably connected with the left side and the right side of the main shaft 6, so that the four driving wheels are always attached to the ground, the driving wheels are prevented from slipping, and the use efficiency of the mower is ensured. When the mower is used on a rugged or large obstacle road surface, the rotary driving device of the mowing frame lifts the mowing frame to a specified height, and the mowing frame is put down to continue weeding after passing through the road surface through four-wheel driving, so that the mowing frame can be protected from being damaged. When the mower is not used, the mower frame can be lifted to an angle vertical to the ground through the frame interlocking device, and the placement space of the mower is saved.
In the invention, the driving motor is an electric motor with a speed reducer, and the power output shaft of the speed reducer can be regarded as the direct power output shaft of the electric motor.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
