    摘要: A mounting assembly (22) for an inside arm C-frame (18) of a bulldozer blade (26) is provided and includes a pair of brackets (30,30, 130,130) joined together by a tractor belly guard (32). Each bracket (30,30, 130,130) is pinned to the tractor frame (12) by a main pin (50) in the upper portion thereof and has a trunnion (52,152) at the lower portion thereof for connection to the arms (20,20) of the C-frame. The forward portions (60,162) of the brackets (30,130) are pinned (74) to the tractor frame (12) in a way as to constrain only that force known as torque or moment of rotational force, generated about said main pin (50). The belly guard (32) can be pivoted down out of the way for servicing the tractor.
