Patent ID: 8756903

Claim:
A work vehicle with a suspended work implement unit, the vehicle comprising: a raising/lowering mechanism for supporting the work implement unit for vertical movement; a manually-operated control device for vertically moving the work implement unit; and a stroke adjustment mechanism for locking the work implement unit with a predetermined stroke position in cooperation with the raising/lowering mechanism based on operational movement of the manually-operated control device, the stroke adjustment mechanism including: a rod having a longitudinal axis; a cam engaging unit mounted on the rod; and a cam member rotatable about longitudinal axis relative to the cam engaging unit and having: a passage portion for allowing passage of at least part of the cam engaging unit in a passage rotational phase, an inclined cam surface portion for producing relative rotation with the cam engaging unit through contact with the cam engaging unit in a cam movement rotational phase region; and a retaining portion for retaining the rod in a retaining rotational phase, wherein the passage rotational phase is produced through engagement between the cam engaging unit and the inclined cam surface portion caused by first operational movement of the manually-operated control device, and the rod is retained by the retaining portion.
