Abstract
A hood support assembly (18) for controllably supporting a hood member (16) on an earth working machine (10) includes a support member (20) that is pivotally mounted, at each of two end portions (22,24) to the frame (12) of the machine. Arm members (26,28) and stop members (42,44) are attached to each of the end portions (22,24) of the support member (20). A pair of adjustable links (34,36) respectively pivotally connect the hood member (16) to each of the arm members (26,28). A pair of springs (52,54) attached to the frame (12) cooperate with the stop members (42,44) to maintain the lateral orientation of the hood member (16) with respect to the frame (12) and support a portion of the weight of the hood member during ground engaging operation of the machine (10).
