Roll over protection apparatus
First Claim
1. An adjustable roll over protection apparatus for an implement having a frame and an operator station, said protection apparatus comprising:
- a roll bar assembly having a generally horizontal cross-piece normally supported above said operator station by at least one upright support member; and
means for adjustably mounting said roll bar assembly to the frame of the implement, said adjustable mounting means defining a generally vertical axis which is substantially colinear with said upright support member and about which the roll bar assembly pivotably moves relative to the implement frame.

Abstract
A roll over protection apparatus which can be angularly and pivotably moved into various positions relative to the frame of an implement. The roll over protection apparatus includes a roll bar assembly and a mechanism for adjustably mounting the roll bar assembly to the implement frame. The mounting mechanism anchors the roll bar assembly in a manner permitting adjustment of the roll bar assembly into a position best suited for the particular application of the implement while maintaining protection for the operator. Locking mechanisms are also permitted for releasably securing the roll bar in adjusted positions relative to the implement frame.

8. An adjustable roll over protection apparatus for an implement having a fore-and-aft extending frame and an operator station, said protection apparatus comprising:
-
a roll bar assembly having a generally horizontal cross-piece normally supported above said operator station by a pair of spaced and generally upright support legs; and means for adjustably mounting said roll bar assembly to said implement frame for pivotable displacement relative thereto, said adjustable mounting means including a pair of spaced attachment assemblies, with each attachment assembly serving to releasably anchor a respective support leg of said roll bar assembly to the implement frame and allowing for movement of the respective support leg about a generally vertical axis such that the cross-piece of the roll bar assembly is movable between a first position whereat it extends laterally across the implement frame and a second position whereat the cross-piece of the roll bar assembly extends fore-and-aft and generally parallel to the implement frame. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An adjustable roll over protection apparatus for an implement having a fore-and-aft extending frame and an operator station, said protection apparatus comprising:
-
a roll bar assembly having a generally horizontal cross-piece normally supported above said operator station a predetermined distance by at least one generally vertical support member; and means for adjustably mounting said roll bar assembly to the implement frame, said adjustable mounting means including an attachment assembly secured to said implement frame to secure a lower section of said vertical support member for pivotal movement relative to said implement frame, said adjustable mounting means further including means defining a generally horizontal axis about which the support member angularly moves to allow the roll bar assembly to be adjustably and angularly positioned relative to the frame while maintaining the cross-piece in a generally fore-and-aft orientation extending generally parallel to the frame. - View Dependent Claims (16, 17, 18, 23)

19. An adjustable roll over protection apparatus comprising:
-
a roll bar assembly having a cross-piece and at least one support member connected to and extending from said cross-piece; and adjustable mounting means arranged toward a lower end of said support member, said adjustable mounting means defining a generally vertical axis which is substantially colinear with said upright member and about which said roll bar assembly is adapted to move. - View Dependent Claims (20, 21, 22)
