Abstract

A riding lawn mower includes a seat, a frame, a mowing element, a deck surrounding, and forming a mowing space for accommodating at least part of the mowing element, and a first motor for driving the mowing element to rotate. The riding lawn mower may further include a footrest provided on a front side of the seat and used to support a user's feet, wherein the footrest comprises a bottom plate and a front cover protruding relative to the bottom plate. The riding lawn mower may include an indicator device for displaying a remaining capacity of the power supply device, and the indicator device is at least partially mounted to the front cover of the footrest.

Claims (37)

1. An electric riding lawn mower comprising:

a seat for a user to sit thereon;

a cutting system comprising a mowing element for cutting vegetation, a deck, and a first motor, the deck surrounding and forming a mowing space for accommodating at least part of the mowing element, and the first motor operably coupled to the mowing element to drive the mowing element to rotate relative to the deck;

a body supporting the seat and the cutting system;

a walking system supporting the body;

a power supply device supplying energy to at least one of the cutting system and the walking system;

an indicator device for displaying a remaining capacity of the power supply device; and

a footrest provided on a front side of the seat and used to support a user's feet, the footrest comprising a bottom plate and a front cover protruding relative to the bottom plate, and the indicator device is at least partially mounted to the front cover of the footrest.

2. The electric riding lawn mower of claim 1 , wherein the body comprises a frame, the frame comprises a first longitudinal beam and a second longitudinal beam, the indicator device comprises an indicator light, and the indicator light is disposed between the first longitudinal beam and the second longitudinal beam.

3. The electric riding lawn mower of claim 2 , wherein a distance from the indicator light to the first longitudinal beam is substantially the same as a distance from the indicator light to the second longitudinal beam.

4. The electric riding lawn mower of claim 1 , wherein the walking system comprises two front walking wheels and two rear walking wheels, and the indicator device are disposed between the two front walking wheels.

5. The electric riding lawn mower of claim 1 , wherein the front cover is formed with a front plane for obliquely supporting the user's feet, and the indicator device is mounted to the front plane.

6. The electric riding lawn mower of claim 1 , wherein the electric riding lawn mower further comprises a front lighting assembly configured to emit light toward a front side area of the electric riding lawn mower, and the front lighting assembly is installed on the front cover.

7. The electric riding lawn mower of claim 5 , wherein the bottom plate is provided with a bottom plane for supporting the user's feet, the bottom plane extends in a first plane, the front plane extends in a second plane, and the second plane obliquely intersects the first plane to form an obtuse angle open toward the user, and the obtuse angle is greater than or equal to 120 degrees and less than or equal to 150 degrees.

8. An electric riding lawn mower comprising:

a seat;

a cutting system comprising a mowing element for cutting vegetation, a deck, and a first motor, the deck surrounding and forming a mowing space for accommodating at least part of the mowing element, and the first motor configured to drive the mowing element to rotate relative to the deck;

a body supporting the seat and the cutting system;

a walking system supporting the body;

a power supply device supplying energy to at least one of the cutting system and the walking system; and

an indicator device displaying a state of a remaining capacity of the power supply device, the indicator comprising an indicator light and in a front and rear direction, the indicator light is disposed on a front side of the deck.

9. The electric riding lawn mower of claim 8 , wherein a distance between the indicator light and the seat is greater than or equal to 300 mm and less than or equal to 1000 mm.

10. The electric riding lawn mower of claim 8 , wherein at least a portion of the power supply device is disposed on a rear side of the seat.

12. The electric riding lawn mower of claim 8 , wherein the electric riding lawn mower further comprises front lighting assemblies configured to emit light toward a front side area of the electric riding lawn mower, the front lighting assemblies comprise a left lighting assembly and a right lighting assembly, and the indicator light disposed between the left lighting assembly and the right lighting assembly.

13. The electric riding lawn mower of claim 8 , wherein the indicator device is disposed on the front side of the seat and emits light toward the seat.

14. The electric riding lawn mower of claim 8 , further comprising a pedal for a user to step on to brake or park the electric riding lawn mower, wherein the indicator light is disposed on the front side of the pedal.

15. An electric riding lawn mower, comprising:

a seat;

a cutting system comprising a mowing element for cutting vegetation, a deck, and a first motor, the deck surrounding and forming a mowing space for accommodating at least part of the mowing element, and the first motor configured to drive the mowing element to rotate relative to the deck;

a body supporting the seat and the cutting system;

a walking system supporting the body;

a power supply device supplying energy to at least one of the cutting system and the walking system;

an indicator device displaying a state of a remaining capacity of the power supply device, wherein in a front and rear direction, the indicator device is disposed on a front side of the deck; and

a display screen comprising a display interface displaying at least one status information.

16. The electric riding lawn mower of claim 15 , wherein the display screen is set on the right side of the seat.
