Abstract

Some embodiments of the invention provide outdoor power equipment including a frame, a seat and at least one leg support angled from a horizontal plane. The outdoor power equipment can include one or more handles, a suspension unit coupled between the frame and the seat. In some embodiments, the seat can be declined with respect to a horizontal plane so that the operator's upper torso leans forward at an angle with respect to a vertical plane when the operator is sitting on the seat.

Claims (36)

1. Outdoor power equipment for use by an operator, the outdoor power equipment comprising:

a frame;

an engine coupled to the frame;

a first drive wheel and a second drive wheel positioned along a drive axis;

at least one handle projecting forward from a vertical plane;

a seat positioned at least partially between the first drive wheel and the second drive wheel and at least partially along the drive axis; and

at least one leg support that is angled with respect to a horizontal plane so that a portion of the operator's body weight is supported by the at least one leg support when the operator is sitting on the seat and when the operator's legs contact the at least one leg support.

2. The outdoor power equipment of claim 1 and further comprising a suspension unit, and wherein the seat and the at least one leg support are suspended with respect to the frame.

3. The outdoor power equipment of claim 2 wherein the least one handle is coupled to the seat and suspended with respect to the frame.

4. The outdoor power equipment of claim 1 wherein the seat is suspended with respect to the frame so that motion of the seat is substantially vertical.

5. The outdoor power equipment of claim 1 and further comprising at least one foot rest coupled to the seat and suspended with respect to the frame.

6. The outdoor power equipment of claim 1 wherein the seat and the at least one leg support are configured and arranged so that when the operator is sitting on the seat and the operator's legs are contacting the at least one leg support an angle between the operator's thighs and the operator's back is greater than about 90 degrees.

7. The outdoor power equipment of claim 1 wherein the seat and the at least one leg support are configured and arranged so that when the operator is sitting on the seat and the operator's legs are contacting the at least one leg support a substantial portion of the operator's body weight is distributed between the operator's pelvis and the operator's knees.

8.

9. The outdoor power equipment of claim 1 wherein the at least one handle is suspended with respect to the frame by a suspension unit.

10. Outdoor power equipment for use by an operator having a body weight, the outdoor power equipment comprising:

a frame at least partially defining a drive axis;

an engine coupled to the frame;

a seat operatively coupled to a portion of the frame and positioned at least partially along the drive axis;

at least one handle projecting forward from a vertical plane and operatively coupled to the seat; and

at least one leg support that is angled with respect to a horizontal plane so that a portion of the operator's body weight is supported by the at least one leg support when the operator is sitting on the seat and when the operator's legs contact the at least one leg support.

11. The outdoor power equipment of claim 10 and further comprising a suspension unit, and wherein the seat and the at least one leg support are suspended with respect to the frame.

12. The outdoor power equipment of claim 11 wherein the seat is suspended with respect to the frame so that motion of the seat is substantially vertical.

13. The outdoor power equipment of claim 11 wherein the seat and the at least one leg support are configured and arranged so that when the operator is sitting on the seat and the operator's legs are contacting the at least one leg support an angle between the operator's thighs and the operator's back is greater than about 90 degrees.

14. The outdoor power equipment of claim 11 wherein the seat and the at least one leg support are configured and arranged so that when the operator is sitting on the seat and the operator's legs are contacting the at least one leg support a substantial portion of the operator's body weight is distributed between the operator's pelvis and the operator's knees.

15. The outdoor power equipment of claim 11 wherein the seat and the at least one leg support are configured and arranged so that when the operator is sitting on the seat and the operator's legs are contacting the at least one leg support, the operator's back, shoulders, and neck are substantially aligned.

16. The outdoor power equipment of claim 10 and further comprising at least one foot rest coupled to the seat and suspended with respect to the frame.

17. Power equipment for use by an operator having a body weight, the power equipment comprising:

a frame;

a first drive wheel and a second drive wheel positioned along a drive axis, the first drive wheel and the second drive wheel operatively coupled to a portion of the frame;

a seat positioned at least partially between the first drive wheel and the second drive wheel and at least partially along the drive axis;

at least one leg support coupled to the frame, being angled with respect to a horizontal plane, and configured and arranged so that a portion of the operator's body weight is supported by the at least one leg support when the operator is sitting on the seat and when the operator's legs contact the at least one leg support; and

at least one handle projecting forward from a vertical plane and operatively coupled to the seat.

18. The power equipment of claim 17 and further comprising an engine coupled to the frame and drivably coupled to at least one of the first drive wheel and the second drive wheel.

19. The power equipment of claim 17 and further comprising a suspension unit, and wherein the seat and the at least one leg support are suspended with respect to the frame.
