Abstract

In certain embodiments, an attachment system for a work vehicle may include a chassis interface coupled to a chassis of the work vehicle. The chassis interface may include a recess extending in a longitudinal direction and a pin retainer having a pin hole extending in a lateral direction. The recess receives a protrusion of an attachment interface coupled to an attachment. The pin hole of the pin retainer receives a pin and the pin fastens the chassis interface and the attachment interface to one another.

First claim

What is claimed is:

1 . A work vehicle adapter, comprising:
a first interface configured to couple to an attachment, wherein the first interface comprises a bolt hole configured to receive a bolt to couple the work vehicle adapter to the attachment; and a second interface configured to couple to a chassis interface, wherein the second interface comprises a first protrusion configured to engage a recess of the chassis interface, and wherein the first protrusion includes a first eyelet configured to receive a pin to couple the work vehicle adapter to the chassis interface, wherein the first eyelet extends in a lateral direction to receive the pin in the lateral direction.

2 . The work vehicle adapter of claim 1 , wherein the second interface comprises a dowel hole configured to receive a dowel pin to block lateral and vertical movement of the work vehicle adapter relative to the chassis interface.

3 . The work vehicle adapter of claim 1 , wherein the second interface comprises a second protrusion configured to engage the recess of the chassis interface, wherein the second protrusion comprises a second eyelet configured to receive the pin to couple the work vehicle adapter to the chassis interface.

4 . The work vehicle adapter of claim 3 , wherein the second protrusion is laterally aligned with the first protrusion.

5 . The work vehicle adapter of claim 3 , wherein the second interface comprises a third protrusion and a fourth protrusion configured to respectively engage the recess of the chassis interface, and wherein the third protrusion and the fourth protrusion are vertically aligned with the first protrusion and the second protrusion, respectively.

6 . The work vehicle adapter of claim 3 , wherein the second protrusion is vertically aligned with the first protrusion.

7 . The work vehicle adapter of claim 1 , wherein the second interface comprises a support structure coupled to the first protrusion.

8 . The work vehicle adapter of claim 1 , wherein the first interface comprises an additional seven bolt holes, wherein each respective bolt hole of the eight bolt holes is configured to receive a respective bolt, wherein a first lateral portion of the second interface comprises two bolt holes of the eight bolt holes, wherein a second lateral portion of the second interface comprises two additional bolt holes of the eight bolt holes, and wherein a top portion of the second interface comprises four bolt holes of the eight bolt holes.

9 . The work vehicle adapter of claim 1 , wherein the work vehicle adapter forms a cavity configured to receive a power take off shaft, a hydraulic component, an electrical component, or a combination thereof.

10 . The work vehicle adapter of claim 1 , wherein the first interface comprises an engagement surface that is machined to engage a corresponding engagement surface of the attachment.

11 . An attachment system for a work vehicle, comprising:
a chassis coupled to a chassis interface, the chassis interface comprising a recess; and an adapter configured to couple to the chassis interface and an attachment, wherein the adapter comprises:
a first interface comprising a bolt hole configured to receive a bolt to couple the adapter to the attachment; and
a second interface comprising a first protrusion configured to engage the recess of the chassis interface, wherein the first protrusion extending in a longitudinal direction comprises a first eyelet configured to receive a first pin extending laterally to couple the adapter to the chassis interface.

12 . The attachment system of claim 11 , wherein the bolt hole extends longitudinally from the first interface to the second interface, and wherein a surface of the first interface is machined.

13 . The attachment system of claim 12 , wherein the bolt hole comprises a recess couplable to a head of the bolt.

14 . The attachment system of claim 11 , wherein the second interface comprises a second protrusion extending in the longitudinal direction and vertically aligned with the first protrusion, and wherein the first protrusion is laterally aligned with a first pin retaining feature of the chassis interface to receive the first pin and the second protrusion is laterally aligned with a second pin retaining feature of the chassis interface to receive a second pin extending laterally.

15 . The attachment system of claim 11 , wherein a first face of the adapter comprises one or more dowel holes, wherein each of the one or more dowel holes receives a dowel pin.

16 . A work vehicle, comprising:
a chassis coupled to a chassis interface comprising pin retaining features on a lateral surface and alignment features on a longitudinal end; an adapter coupled to an attachment, wherein the adapter comprising a first protrusion extending from a longitudinal end of the adapter and configured to be received by the alignment features of the chassis interface to couple the attachment to the chassis; and a pin assembly comprising a pin extending laterally and configured to engage an eyelet of the first protrusion and the pin retaining feature of the chassis interface to couple the adapter to the chassis.

17 . The work vehicle of claim 16 , wherein the adapter comprises one or more bolt holes extending from a first interface of the adapter longitudinally to a second interface of the adapter, and wherein the one or more bolt holes is configured to receive a bolt to couple the adapter to the attachment.

18 . The work vehicle of claim 17 , wherein the adapter comprises one or more dowel holes extending from the first interface of the adapter longitudinally to the second interface of the adapter, and wherein the one or more dowel holes is configured to receive a dowel pin.

19 . The work vehicle of claim 16 , wherein the adapter comprises a second protrusion extending from the longitudinal end of the adapter and configured to be received by the alignment features of the chassis interface, and wherein the second protrusion is vertically aligned with the first protrusion.

20 . The work vehicle of claim 19 , wherein the second protrusion extends from a baseplate of the adapter.
