Abstract:
A dual mode stabilizer for a tractor, said dual mode stabilizer comprising:at least one base member rigidly fixable proximate a side of the tractor, said at least one base member having an upper end and a lower end; a clevis disposed proximate said lower end of said at least one base member, wherein said clevis defines a stop; a stabilizer arm assembly engaged with said base member having an outrigger arm member and a sliding arm member, said outrigger arm member and said sliding arm member being pivotally connected together at a pivot point so as to allow rotational movement of said outrigger arm member relative to said sliding arm member, said pivot point being engageable with said stop so as to limit upward travel of said stabilizer arm assembly relative to said base member; a mechanism in association with said base member and said sliding arm member for limiting movement of said sliding arm member relative to said base member to axial movement; a first locking mechanism interconnecting said outrigger arm member and said sliding arm member for preventing rotational movement of said outrigger arm member around said pivot point; a second locking mechanism interconnecting said base member and said sliding arm member for preventing axial movement of said sliding member relative to said base member; a drive mechanism connected between said base member and said stabilizer arm assembly for actuating said stabilizer arm assembly whereby said dual mode stabilizer is selectively operable in a vertical stabilizer mode and a fold down stabilizer mode; and a mounting member carried by said base member and at least an upper and at least a lower mounting bracket secured to said mounting member, said mounting member and said upper and lower mounting brackets being adapted for securing said dual mode stabilizer to a rubber-tire backhoe loader.
