Abstract

A riding mower includes a seat, a main rack configured to bear the seat, a mowing element, a walking assembly for enabling the riding mower to walk across a lawn, and an operation assembly configured to be operated by the user so that the riding mower is controlled to walk and output power. The riding mower further includes a parking system, a linkage mechanism and a gearbox. The parking system is configured to switch the riding mower between a parking state and a non-parking state. The linkage mechanism is connected to the parking system. The gearbox is connected to the linkage mechanism. The parking system controls, through the linkage mechanism, the gearbox to implement braking.

First claim

What is claimed is:

1. A riding mower, comprising:
a seat;
a main rack configured to bear the seat;
a mowing element;
a walking assembly;
an operation assembly configured to be operated by the user so that the riding mower is controlled to walk and output power;
a parking system configured to switch the riding mower between a parking state and a non-parking state;
a linkage mechanism connected to the parking system; and
a gearbox connected to the linkage mechanism;
wherein the parking system is configured to control, through the linkage mechanism, the gearbox to implement braking whereby, when the parking system is locked, the riding mower is in the parking state and, when the parking system is not locked, the riding mower is in the non-parking state.

2. A riding mower, comprising:
a seat;
a main rack configured to bear the seat;
a mowing element;
a walking assembly;
an operation assembly configured to be operated by the user so that the riding mower is controlled to walk and output power;
a parking system configured to switch the riding mower between a parking state and a non-parking state;
a linkage mechanism connected to the parking system; and
a gearbox connected to the linkage mechanism,
wherein the parking system is configured to control, through the linkage mechanism, the gearbox to implement braking whereby, when the parking system is locked, the riding mower is in the parking state and, when the parking system is not locked, the riding mower is in the non-parking state, and
wherein the parking system comprises a pedal assembly configured to be operated by the user so that the riding mower is switched between the parking state and the non-parking state, a base plate configured for mounting the pedal assembly, a cover plate configured to cooperate with the base plate so that the cover plate and the base plate are connected to the pedal assembly, a ratchet connected to the pedal assembly, and a first elastic member connected between the pedal assembly and the base plate.

3. The riding mower of claim 2 , wherein the pedal assembly comprises a pedal, a first rotator connected to the pedal, and a pedal arm, the first rotator and the pedal are capable of rotating about a center axis synchronously, and one end of the pedal arm is connected to the pedal and the other end of the pedal arm is connected to the first rotator.

4. The riding mower of claim 3 , wherein the first rotator is reset in a second direction under influence of the first elastic member when the pedal is not being depressed by a user.

5. The riding mower of claim 2 , wherein the parking system further comprises a second rotator connected to the base plate, a second elastic member connected between the base plate and the cover plate and formed with a snap ring, and the snap ring abuts against the second rotator.

6. The riding mower of claim 5 , wherein the second rotator is formed with an accommodation recess and the snap ring of the second elastic member is mounted in the accommodation recess and capable of switching between a first position and a second position.

7. The riding mower of claim 5 , wherein an elastic force of the first elastic member is greater than an elastic force of the second elastic member.

8. The riding mower of claim 5 , wherein the second rotator is formed with or connected to a pawl and the pawl is capable of limiting a rotation direction of the ratchet.

9. The riding mower of claim 5 , wherein the cover plate is formed with a first stopper abutting against the second rotator and a second stopper configured to limit a rotation angle of the second rotator.

10. The riding mower of claim 5 , wherein the parking system further comprises a third rotator, the third rotator is securely connected to or integrally formed with the second rotator, and the third rotator cooperates with a first protrusion of the base plate to switch the second elastic member from the second position to the first position.
