Abstract

A utility vehicle is disclosed. The utility vehicle is configured to support a removable implement. The removable implement may include one or more components configured to be powered by a power take off system of the utility vehicle. The removable implement may also include one or more components configured to be powered by a hydraulic system of the utility vehicle. An operator of the utility vehicle, without exiting a cab of the utility vehicle, can couple the implement to the utility vehicle such that the hydraulic components are hydraulically coupled to the vehicle's hydraulic system and such that the components of the implement configured to be powered by a power take off system of the utility vehicle are operably coupled to the power take off system of the utility vehicle.

First claim

The invention claimed is:

1. A utility vehicle comprising:
a power take off system configured to deliver power to a removable implement coupled to the utility vehicle,
a power take off driving member coupled to the power take off system of the utility vehicle, the power take off driving member including a body and a plurality of lobes radially emanating from the body of the power take off driving member; and
a power take off receiving member configured to interface with the power take off driving member, the power take off receiving member including a body and a plurality of lobes radially emanating from the body of the power take off receiving member, each adjacent radially emanating lobe of the power take off receiving member having a reaction member projecting therefrom, the power take off receiving member being coupleable to the removable implement,
wherein each adjacent radially emanating lobe of the power take off driving member engages a reaction member of the power take off receiving member to cause the power take off receiving member to rotate and wherein the power take off driving member and the power take off receiving member are brought into contact and are coupled without manual intervention, and
wherein the power take off receiving member is able to translate along a longitudinal axis of a driveshaft of the removable implement to change the axial position of the reaction member relative to the power take off driving member.

2. The utility vehicle of claim 1 , wherein the power take off driving member is coupled to a drive shaft of the utility vehicle.

3. The utility vehicle of claim 1 , wherein
at least one of the plurality of lobes includes a first end adjacent the body and defines a first lateral width, and a head radially spaced from the first end and defining a second lateral width larger than the first lateral width.

4. The utility vehicle of claim 1 , wherein the power take off driving member is coupled to a drive shaft of the utility vehicle.

5. The utility vehicle of claim 1 , wherein the power take off driving member is operable to self-align with the power take off receiving member.

6. The utility vehicle of claim 5 , wherein the power take off driving member is operable to be actuated to correct a misalignment between the plurality of lobes of the power take off driving member and the reaction members of the power take off receiving member.

7. The utility vehicle of claim 6 , wherein when misaligned, actuation of the power take off driving member causes relative rotation between the power take off driving member and the power take off receiving member until the lobes of the power take off driving member align with respective voids adjacent each adjacent reaction member of the power take off receiving member.

8. The utility vehicle of claim 1 , wherein the power take off receiving member of the removable implement is decoupled from the power take off driving member of the vehicle contemporaneously with a decoupling of the removable implement from the utility vehicle.

9. The utility vehicle of claim 1 , further comprising at least one resilient member positioned between the power take off receiving member and an operating unit portion of the removable implement.

10. A power transfer system configured for transferring power from a utility vehicle to at least one removable implement that is coupleable to the utility vehicle such that at least one system of the at least one removable implement can be powered by the utility vehicle, the system comprising:
a power take off driving member coupleable to a power take off system of the utility vehicle, the power take off driving member including a body and a plurality of lobes radially emanating from the body of the power take off driving member; and
a power take off receiving member configured to interface with the power take off driving member, the power take off receiving member including a body and a plurality of lobes radially emanating from the body of the power take off receiving member, each adjacent radially emanating lobe of the power take off receiving member having a reaction member projecting therefrom, the power take off receiving member being coupleable to the at least one removable implement,
wherein each adjacent radially emanating lobe of the power take off driving member engages a reaction member of the power take off receiving member to cause the power take off receiving member to rotate and wherein the power take off driving member and the power take off receiving member are brought into contact and are coupled without manual intervention, and
wherein the power take off receiving member is free to translate along a longitudinal axis of a driveshaft of the removable implement to change the axial position of the reaction member relative to the power take off driving member.

11. The power transfer system of claim 10 , wherein
at least one of the plurality of lobes includes a first end adjacent the body and defines a first lateral width, and a head radially spaced from the first end and defining a second lateral width larger than the first lateral width.

12. The system of claim 11 , wherein a plurality of forward faces on the lobes of the power take off receiving member are parallel to each other and perpendicular to a longitudinal axis of the power take off receiving member.

13. The system of claim 10 , wherein the power take off driving member is coupleable to a drive shaft of the utility vehicle.
