Abstract

A mounting system for a work vehicle includes: an axle; a final drive coupled to the axle and configured to rotate a wheel mounted to the final drive; and a pivot plate coupling the final drive to the axle. The pivot plate includes a first arrangement of plate mounting features and a second arrangement of plate mounting features that differs from the first arrangement of plate mounting features, the final drive including at least one set of drive mounting features and being rotatable from a first orientation where the at least one set of drive mounting features is aligned with the first arrangement of plate mounting features to a second orientation where the at least one set of drive mounting features is aligned with the second arrangement of plate mounting features.

First claim

What is claimed is:

1 . A mounting system for a work vehicle, said mounting system comprising:
an axle; a final drive coupled to the axle and configured to rotate a wheel mounted to the final drive; and a pivot plate coupling the final drive to the axle, wherein the pivot plate comprises a first arrangement of plate mounting features and a second arrangement of plate mounting features that differs from the first arrangement of plate mounting features, the final drive comprising at least one set of drive mounting features and being rotatable from a first orientation where the at least one set of drive mounting features is aligned with the first arrangement of plate mounting features to a second orientation where the at least one set of drive mounting features is aligned with the second arrangement of plate mounting features.

2 . The mounting system of claim 1 , wherein the first arrangement of plate mounting features and/or the second arrangement of plate mounting features and/or the at least one set of drive mounting features comprises a plurality of mounting openings.

3 . The mounting system of claim 2 , wherein at least the first arrangement of plate mounting features and the second arrangement of plate mounting features each comprise a plurality of mounting openings.

4 . The mounting system of claim 2 , wherein all of the first arrangement of plate mounting features, the second arrangement of plate mounting features, and the at least one set of drive mounting features each comprise a plurality of mounting openings.

5 . The mounting system of claim 1 , further comprising an actuator coupled to the axle and configured to adjust a height of the axle.

6 . The mounting system of claim 1 , wherein the pivot plate comprises a shaft opening that is sized to allow an input shaft to extend therethrough and couple to the final drive when the final drive is in the first orientation and the second orientation.

7 . A driveline for a work vehicle, comprising:
the mounting system of claim 1 ; and an input shaft coupled to the final drive and configured to drive the final drive and rotate the wheel mounted thereto.

8 . The driveline of claim 7 , wherein the input shaft is configured to couple with the final drive in both the first orientation and the second orientation while the input shaft is in a set position.

9 . The driveline of claim 8 , wherein the shaft opening defines an opening diameter (OD) that is greater than a shaft diameter (SD) of the input shaft.

10 . The driveline of claim 9 , wherein the opening diameter (OD) is at least two times greater than the shaft diameter (SD) of the input shaft.

11 . The driveline of claim 9 , wherein the opening diameter (OD) is at least three times greater than the shaft diameter (SD) of the input shaft.

12 . The driveline of claim 7 , wherein the input shaft extends through a shaft opening formed in the pivot plate.

13 . The driveline of claim 7 , wherein the final drive is configured to rotate about the input shaft from the first orientation to the second orientation.

14 . The driveline of claim 7 , further comprising an actuator coupled to the axle and configured to adjust a height of the axle.

15 . The driveline of claim 14 , wherein the actuator is configured to adjust the height of the axle without adjusting a height of the input shaft.

16 . A work vehicle, comprising:
a chassis; the driveline of claim 7 carried by the chassis; and the wheel mounted to the final drive of the driveline.

17 . The work vehicle of claim 16 , wherein the wheel defines a first diameter when the final drive is in the first orientation or defines a second diameter that differs from the first diameter when the final drive is in the second orientation.

18 . A method for successively mounting a first wheel and a second wheel to a work vehicle, said work vehicle comprising an axle, a final drive coupled to the axle and configured to rotate either the first wheel or the second wheel that is mounted to the final drive, and a pivot plate coupling the final drive to the axle, wherein the final drive comprises at least one set of drive mounting features, and wherein the pivot plate comprises a first arrangement of plate mounting features and a second arrangement of plate mounting features that differs from the first arrangement of plate mounting features, said method comprising:
coupling the at least one set of drive mounting features to the first arrangement of plate mounting features while the final drive is in a first orientation; mounting the first wheel to the final drive, the first wheel defining a first diameter; dismounting the first wheel from the final drive; uncoupling the at least one set of drive mounting features from the first arrangement of plate mounting features; rotating the final drive to a second orientation that differs from the first orientation; coupling the at least one set of drive mounting features to the second arrangement of plate mounting features while the final drive is in the second orientation; and mounting the second wheel to the final drive, the second wheel defining a second diameter that differs from the first diameter.

19 . The method of claim 18 , wherein a vertical level of the work vehicle when the first wheel is mounted to the final drive is the same as the vertical level of the work vehicle when the second wheel is mounted to the final drive.
