<p>A lift arm assembly (24) for a small or 'mini' track driven loader (10) is pivotally mounted onto a self propelled frame (12) for movement between a raised and a lowered position. A support strut (60) is provided that fits over an extended rod (29) of the lift arm operating cylinder (26) with the lift arm assembly (24) raised, and will prevent the lift arm assembly (24) from lowering. The support strut (60) is stored in a front tubular cross member (70) of the lift arm assembly (24). Additionally, the front cross member (70) supports an upright strut (44) that acts as a back stop for material in a bucket (48), so that if an object in the bucket (48) tends to roll rearwardly, it will be deflected or stopped. Each lift arm (24A, 24B) has a rear portion (25) extending downwardly and forwardly to join side portions (32) of the lift arms (24A, 24B) that are substantially parallel to the hydraulic actuators (26) used and parallel to the upper lengths (14U) of the respective drive tracks (14D) in a lowered position of the lift arm assembly (24).</p> |
