Abstract

Techniques and/or systems are disclosed for an implement attachment assembly for a work vehicle. The implement attachment assembly includes a member having a body extending longitudinally between a first end and a second end. The first end includes a central axis disposed at a first height relative to a member vertical axis and the second end includes a central axis disposed at a second height relative to the member vertical axis. The first end central axis is operably disposed at a different height than the second end central axis. The first end is configured to operably connect to the work vehicle. The second end is configured to operably connect to a coupling device.

First claim

What is claimed is:

1. An implement attachment assembly for a work vehicle, the implement attachment assembly comprising:
a member having a single, monolithic body extending longitudinally between a first end and a second end, the first end comprising a central axis disposed at a first height h 1 relative to a member vertical axis and the second end comprising a central axis disposed at a second height h 2 relative to the member vertical axis, wherein the member body is hollow;
wherein the first end central axis is operably disposed at a different height than the second end central axis, and
wherein the first end is configured to operably connect to the work vehicle and the second end is configured to operably connect to a coupling device.

2. The implement attachment assembly of claim 1 , wherein the first height h 1 is greater than the second height h 2 and the slope of the body tends to decline moving in the longitudinal direction from the first end to the second end.

3. The implement attachment assembly of claim 1 , wherein the member operably accommodates a PTO shaft assembly that is operably coupled with a PTO clutch assembly.

4. The implement attachment assembly of claim 1 , wherein the member comprises a tie-down loop fixedly engaged at the bottom of the member.

5. The implement attachment assembly of claim 1 , wherein the coupling device is formed integral with the member.

6. The implement attachment assembly of claim 1 , wherein the coupling device is a clevis comprising:
a clevis body;
a first arm extending from the clevis body, the first arm having a bore; and
a second arm extending from the clevis body, the second arm having a bore,
wherein the respective bores are aligned with each other and define a pin insertion axis.

7. The implement attachment assembly of claim 6 , further comprising a set of wear bodies removably mounted to the clevis to operably provide a physical barrier between the clevis and an inserted pin, the set of wear bodies comprising:
a first bushing selectably mountable in the first arm bore;
a second bushing selectably mountable in the second arm bore; and
a wear plate which is selectably mountable to the clevis body, wherein the wear plate engages the first bushing to support the first bushing within the first arm bore, wherein the wear plate engages the second bushing to support the second bushing within the second arm bore.

8. The implement attachment assembly of claim 6 , further comprising a pin which is selectably insertable into the bores along the pin insertion axis, the pin comprising:
a shaft,
a collar disposed at an end of the shaft, wherein the collar comprises a plate engagement member,
a pin bore extending into a center of the pin through the plate engagement member and collar along a longitudinal axis of the pin;
a plate comprising a body, the body comprising a receiving slot at one end and a hole at another end, the receiving slot configured to receive the plate engagement member, wherein the plate engagement member and receiving slot cooperate to operably mitigate rotational movement of the pin relative to the plate;
a mounting plate having a mounting plate bore, the mounting plate disposed over the mated combination of the plate engagement member and the plate with the mounting plate bore aligned with the pin bore; and
a fastener selectably insertable through the mounting plate bore and into the pin bore to fixedly assemble the pin.

9. The implement attachment assembly of claim 6 , wherein the clevis further comprises:
a pair of tabs disposed on top of the clevis body, each tab having an opening, wherein the openings are aligned with each other to define a cross pin insertion axis extending orthogonal to the direction of the member vertical axis;
a cross pin selectably mountable in the openings;
a receiving cavity disposed in the top of the clevis body; and
a dowel pin which is insertable into the receiving cavity.

10. The implement attachment assembly of claim 1 , wherein the member comprises an integrated storage container and a storage container cover removably attached to the member.

11. An implement attachment assembly for a work vehicle, the implement attachment assembly comprising:
a member having a hollow body extending longitudinally between a first end and a second end, the first end comprising a central axis disposed at a first height h 1 relative to a member vertical axis and the second end comprising a central axis disposed at a second height h 2 relative to the member vertical axis,
wherein the first height h 1 is greater than the second height h 2 and the body has a downward sloping curved surface moving in a longitudinal direction from the first end to the second end,
wherein the first end is configured to operably connect to the work vehicle and the second end is configured to operably connect to a coupling device.

12. The implement attachment assembly of claim 11 , wherein the member operably accommodates a PTO shaft assembly that is operably coupled with a PTO clutch assembly.

13. The implement attachment assembly of claim 11 , wherein the member comprises a tie-down loop fixedly engaged at the bottom of the member.

14. The implement attachment assembly of claim 11 , wherein the coupling device is formed integral with the member.

15. The implement attachment assembly of claim 11 , wherein the coupling device is a clevis comprising:
a clevis body;
a first arm extending from the clevis body, the first arm having a bore; and
a second arm extending from the clevis body, the second arm having a bore,
wherein the respective bores are aligned with each other and define a pin insertion axis.

16. The implement attachment assembly of claim 15 , further comprising a set of wear bodies removably mounted to the clevis to operably provide a physical barrier between the clevis and an inserted pin, the set of wear bodies comprising:
a first bushing selectably mountable in the first arm bore;
a second bushing selectably mountable in the second arm bore; and
a wear plate which is selectably mountable to the clevis body, wherein the wear plate engages the first bushing to support the first bushing within the first arm bore, wherein the wear plate engages the second bushing to support the second bushing within the second arm bore.

17. The implement attachment assembly of claim 15 , further comprising a pin which is selectably insertable into the bores along the pin insertion axis, the pin comprising:
a shaft,
a collar disposed at an end of the shaft, wherein the collar comprises a plate engagement member,
a pin bore extending into a center of the pin through the plate engagement member and collar along a longitudinal axis of the pin;
a plate comprising a body, the body comprising a receiving slot at one end and a hole at another end, the receiving slot configured to receive the plate engagement member, wherein the plate engagement member and receiving slot cooperate to operably mitigate rotational movement of the pin relative to the plate;
a mounting plate having a mounting plate bore, the mounting plate disposed over the mated combination of the plate engagement member and the plate with the mounting plate bore aligned with the pin bore; and
a fastener selectably insertable through the mounting plate bore and into the pin bore to fixedly assemble the pin.

18. The implement attachment assembly of claim 15 , wherein the clevis further comprises:
a pair of tabs disposed on top of the clevis body, each tab having an opening, wherein the openings are al
