A dual mode stabilizer (10) for use with a backhoe loader or a backhoe attachment. The stabilizer (10) includes a pair of base memers (20) fixed on opposite sides of the tractor (15). A stabilizer arm assembly (30) engages the base member (20). The stabilizer arm assembly (30) is piston (60) actuated and includes an outrigger arm member (65) a sliding arm member (70) pivotally connected to the outrigger arm member (65), a first locking mechanism and a second locking mechanism. Actuation of the piston (60) with the first locking mechanism engaged, causes the stabilizer arm assembly (30) to travel downwardly within the base member providing operation in the vertical mode. Actuaction of the piston (60) with the first locking mechanism released and the second locking mechanism engaged, causes the outrigger arm member (65) to rotate about a first pivot point (75) resulting in operation in the fold down mode.
