This invention relates to the field of lawnmower technology, specifically a gasoline-powered multi-functional lawnmower, including an engine mounting bracket. An engine is mounted on one side of the mounting bracket, and the engine output end passes through the mounting bracket and is connected to a drive shaft. A drive housing is mounted on the side of the mounting bracket away from the engine. A movable drive mechanism is provided inside the drive housing. When the drive mechanism is poweredly connected to the drive shaft, the drive shaft drives the moving wheels to rotate through the drive mechanism.

In this embodiment, the engine 2, the drive shaft 3, and other components of the mower are not modified, so the principle of the engine 2, the control switch, and the like can be arranged in the same manner as in the prior art.
The specific working principle of the above embodiment is as follows:
When the mower is used, an operator starts the engine 2, and the engine 2 drives the driving shaft 3 and the cutter disc 4 to rotate, so that weeds are cut by the cutter disc 4;
In the cutting process, when the road condition of the cutting machine walking is a flat ground or a dry road surface, an operator directly holds the push rod 9 and pushes the cutting machine, so that the movable wheel 5 moves, and the cutting is changed while the movement is realized;
When the road condition of the cutter walking is sloping field or muddy road, an operator pulls the handle on the brake handle 10 to enable the handle to swing around the brake handle seat body, so that the steel wire pull rope 82 is pulled to move, the steel wire pull rope 82 moves to pull the two first rotating seats 712 to move along the first concave mounting seats 711, so that the driving rod 713 and the worm wheel 714 are driven to move, the worm wheel 714 is meshed with the worm on the driving shaft 3, and the driving shaft 3 can drive the worm wheel 714 to rotate;
In the process of moving the driving rod 713, the tension of the chain 74 is changed to drive the tension wheel 735 and the second rotating seat 733 to move along the limiting rod 732, so that the position of the tension wheel 735 is changed to adjust the tension of the chain 74, and the normal operation of the chain 74 is ensured;
The worm wheel 714 rotates to drive the driving rod 713 and the driving wheel 715 to rotate, and the driving wheel 715 drives the driven wheel 72 and the rotating shaft 51 to rotate through the chain 74, so that the moving wheel 5 can automatically rotate, an operator can operate more labor-saving, and after the road condition is recovered to be normal, the operator only needs to loosen the handle, the steel wire stay 82 returns to the original position under the action of the restoring force of the spring 736 and the gravity of the first rotating seat 712, and accordingly the worm wheel 714 is separated from the worm, and automatic walking is finished.
