Abstract

A baler includes a body, and a wrap system that is attached to the body. The wrap system is operable to support a roll of wrap material in an installed position. A cover is attached to the body, and is moveable between an open position and a closed position. When in open position, the cover provides access to the wrap system from an exterior location. When in the closed position, the cover encloses the wrap system from the exterior location. The baler includes a lift system attached to one of the body and the cover. The lift system is concealed between the body and the cover when the cover is disposed in the closed position. The lift system is positioned below the cover when the cover is disposed in the open position. The lift system raises the roll of wrap material into the installed position.

First claim

What is claimed is:

1 . A baler comprising:
a body; a wrap system attached to the body and operable to support a roll of wrap material in an installed position; a cover attached to the body and moveable between an open position providing access to the wrap system from an exterior location, and a closed position enclosing the wrap system from the exterior location; and a lift system attached to one of the body and the cover and concealed between the body and the cover when the cover is disposed in the closed position, wherein the lift system is operable to raise the roll of wrap material, relative to the body, into the installed position.

2 . The baler set forth in claim 1 , wherein the lift system is positioned below the cover when the cover is disposed in the open position.

3 . The baler set forth in claim 1 , wherein the lift system includes a lift location positionable at an elevation disposed above the installed position of the roll of wrap material, when the cover is disposed in the open position.

4 . The baler set forth in claim 1 , wherein the lift system includes a line actuator having a line, with the line extending from the lift location downward for engagement with the roll of wrap material.

5 . The baler set forth in claim 4 , wherein the line actuator is one of an electrically driven winch or a manually operated winch.

6 . The baler set forth in claim 4 , wherein the lift system includes a cover support interconnecting the cover and the body and operable to secure the cover relative to the body when the cover is disposed in the open position.

7 . The baler set forth in claim 6 , wherein the line actuator is directly attached to the cover.

8 . The baler set forth in claim 6 , wherein the lift system includes a lift structure directly attached to the cover to define the lift location.

9 . The baler set forth in claim 6 , wherein the cover includes a cover structure, with the cover support and the cover structure operable to support the cover in the open position against a weight of the roll of wrap material while raising the roll of wrap material, without permanent deformation.

10 . The baler set forth in claim 4 , wherein the lift system includes a jib rotatable attached to the body for rotation about a first vertical axis on a substantially horizontal plane relative to a ground surface.

11 . The baler set forth in claim 10 , wherein the jib extends from the body to a distal end, with the distal end of the jib defining the lift location.

12 . The baler set forth in claim 11 , wherein the line actuator is attached to the jib.

13 . The baler set forth in claim 12 , wherein the jib includes a first member attached to the body for rotation about the first vertical axis on the substantially horizontal plane, and a second member rotatably attached to the first member for rotation about a second vertical axis on the substantially horizontal plane, with the second member defining the distal end of the jib.

14 . The baler set forth in claim 10 , wherein the jib is moveable relative to the body between a stowed position with the jib nestled against the body and out of interference with the cover when the cover is disposed in the closed position, and an operating position with the jib extending away from the body for presenting the lift location in a position for raising the roll of wrap material.

15 . The baler set forth in claim 14 , wherein the jib is rotatably attached to the body for rotation about a horizontal axis for movement between a first elevated position and a second elevated position.

16 . The baler set forth in claim 1 , wherein the wrap system is operable to support a second roll of wrap material in a storage position, and wherein the lift system is at least partially disposed in a region positioned vertically between the roll of wrap material in the installed position and the second roll of wrap material in the storage position when the cover is disposed in the closed position.

17 . A baler for accumulating cut crop material and forming the crop material into a round bale, the baler comprising:
a body; a wrap system attached to the body and operable to support a roll of wrap material in an installed position; a lift system attached to the body and operable to raise the roll of wrap material, relative to the body, into the installed position; wherein the lift system includes:
a jib rotatable attached to the body for rotation about a first vertical axis on a substantially horizontal plane relative to a ground surface; and
a line actuator attached to the jib, wherein the line actuator includes a line, and is operable to retract and extend the line for raising and lowering the roll of wrap material.

18 . The baler set forth in claim 17 , wherein the jib extends from the body to a distal end, with the distal end of the jib defining a lift location positionable at an elevation disposed above the installed position of the roll of wrap material.

19 . The baler set forth in claim 18 , wherein the jib includes a first member attached to the body for rotation about the first vertical axis on the substantially horizontal plane, and a second member rotatably attached to the first member for rotation about a second vertical axis on the substantially horizontal plane, with the second member defining the distal end of the jib, and including the line actuator.

20 . A baler comprising:
a body; a cover attached to the body and moveable between an open position for providing access to a roll of wrap material from an exterior location, and a closed position for enclosing the roll of wrap material from the exterior location; and a lift system attached to one of the body and the cover and concealed between the body and the cover when the cover is disposed in the closed position, wherein the lift system is operable to raise the roll of wrap material, relative to the body.
