Abstract

A snow plow is pivotally mounted to a tractor by a compound mount allowing for multiple blade positions. The mount has an inner portion pivotally mounted about a first horizontal axis to the front of the tractor and an outer portion pivotally mounted about a vertical axis to the inner portion. The plow blade is pivotally mounted about a second horizontal axis to the outer portion. Deicer nozzles spray liquid and a spreader distributes salt and other materials in front of the front wheels of the tractor.

First claim

What is claimed is:

1. A snow removal system comprising:
a skid steer vehicle comprising
a frame having a front end, a rear end, a first side extending between the front end and the rear end, and a second side extending between the front end and the rear end,
a first plurality of rotating elements mounted on the first side of the frame and a second plurality of rotating elements mounted on the second side of the frame, wherein the first plurality of rotating elements and the second plurality of rotating elements are configured to drive the skid steer vehicle over a supporting surface,
a power source operatively connected to the first plurality of rotating elements and the second plurality of rotating elements,
controls operatively connected to the power source to control rotation of the first plurality of rotating elements independent of the second plurality of rotating elements, and
a standing platform arranged rearward of at least a portion of the power source;

a snow plow; and
a mount movably connecting the snow plow to the frame, the mount comprising
a proximal end portion pivotably mounted about a first substantially horizontal axis to the front end of the frame,
a distal end portion pivotably mounted about a second substantially horizontal axis to the snow plow, and
the distal end portion being pivotable relative to the proximal end portion about a substantially vertical axis,
wherein the first substantially horizontal axis is in front of at least a portion of a frontmost rotating element of the first plurality of rotating elements.

2. The snow removal system of claim 1 , comprising a pitch actuator mounted to the front end of the frame and configured to move the snow plow between a down position and an up position by causing the snow plow to rotate about the first substantially horizontal axis.

3. The snow removal system of claim 1 , the skid steer vehicle being free of a seat for an operator.

4. The snow removal system of claim 1 , the controls being mounted atop a substantially vertical structure arranged forward of at least a portion of the standing platform.

5. The snow removal system of claim 4 , the substantially vertical structure including a substantially vertical panel arranged rearward of the controls and forward of the at least a portion of the standing platform.

6. The snow removal system of claim 1 , the controls defining an uppermost portion of the skid steer vehicle.

7. The snow removal system of claim 1 , wherein the first plurality of rotating elements includes a first pair of wheels in contact with the supporting surface, and the second plurality of rotating elements includes a second pair of wheels in contact with the supporting surface.

8. The snow removal system of claim 1 , comprising a spreader system including a rotating spreader element mounted to the frame to dispense salt downwardly in front of the first plurality of rotating elements and second plurality of rotating elements.

9. The snow removal system of claim 1 , comprising a spray system including at least one nozzle connected to a liquid storage tank and mounted to the front end of the vehicle frame to spray liquid downwardly in front of the first plurality of rotating elements and second plurality of rotating elements.

10. The snow removal system of claim 1 , comprising a power source including a hydraulic pump in fluid communication with a source of hydraulic fluid.

11. The snow removal system of claim 10 , comprising a pitch hydraulic cylinder in fluid communication with the source of hydraulic fluid and configured to move the snow plow between a down position and an up position by causing the snow plow to rotate about the first substantially horizontal axis.

12. The snow removal system of claim 11 , comprising a yaw hydraulic cylinder in fluid communication with the source of hydraulic fluid and configured to angle the snow plow relative the frame by causing the snow plow to rotate about the substantially vertical axis.

13. The snow removal system of claim 12 , comprising a plurality of valves, each valve of the plurality of valves being in fluid communication with the hydraulic pump, the plurality of valves allowing an operator to independently control at least: (i) rotation of the first plurality of rotating elements, (ii) rotation of the second plurality of rotating elements, (iii) actuation of the pitch hydraulic cylinder, and (iv) actuation of the yaw hydraulic cylinder.

14. The snow removal system of claim 1 , comprising a plurality of individually operable hydraulic motors each being coupled to a respective rotating element of the first and second pluralities of rotating elements.

15. A snow removal system comprising:
a skid steer vehicle comprising
a frame having a front end, a rear end, a first side extending between the front end and the rear end, and a second side extending between the front end and the rear end,
a first plurality of rotating elements mounted on the first side of the frame and a second plurality of rotating elements mounted on the second side of the frame, wherein the first plurality of rotating elements and the second plurality of rotating elements are configured to drive the skid steer vehicle over a supporting surface,
a power source operatively connected to the first plurality of rotating elements and the second plurality of rotating elements,
controls operatively connected to the power source to control rotation of the first plurality of rotating elements independent of the second plurality of rotating elements,
a standing platform, and
wherein the controls are mounted atop a substantially vertical structure arranged forward of at least a portion of the standing platform;

a snow plow movably connected to the front end of the frame; and
a mount movably connecting the snow plow to the frame, the mount comprising
a proximal end portion pivotably mounted about a first substantially horizontal axis to the front end of the frame, and
a distal end portion pivotably mounted about a second substantially horizontal axis to the snow plow,
wherein the first substantially horizontal axis is in front of at least a portion of a frontmost rotating element of the first plurality of rotating elements.

16. The snow removal system of claim 15 , the substantially vertical structure including a substantially vertical panel arranged rearward of the controls and forward of the at least a portion of the standing platform.

17. The snow removal system of claim 16 , the controls defining an uppermost portion of the skid steer vehicle.

18. The snow removal system of claim 15 , comprising a mount movably connecting the snow plow to the frame, the mount comprising:
a proximal end portion pivotably mounted about a first substantially horizontal axis to the front end of the frame;
a distal end portion pivotably mounted about a second substantially horizontal axis to the snow plow; and
the distal end portion being pivotable relative to the proximal end portion about a substantially vertical axis.

19. The snow removal system of claim 15 , comprising a plurality of individually operable hydraulic motors each being coupled to a respective rotating element of the first and second pluralities of rotating elements.
