At the same time, a lifting cylinder (11) is connected to the track frame (1) via a support shaft (73), and a tip of a piston rod (74) of the cylinder (11) is connected to an intermediate portion of a movable plate (69). To the movable plate (69) through a pin (75).
6) The pin (75) is removably inserted through the piston rod (74) via the piston rod (74), and the pin (75) is fixed to the movable plate (69) by bolts (77), while the fixed plate (68) and the movable plate (68) are movable. Openings (78) and (79) on the inclined lower end side of the plate (69)
A pin (80) is removably inserted through the fixing plate (68).
The pin (80) is fixedly fastened to the bolt (81) with a fixed plate (68) and a movable plate (69) as shown in FIG.
Are alternately arranged in a staggered manner, and a bracket (70) is provided on the lower surface on the right side of the main beam (34).
The lifting cylinder (11) is disposed on the right side of the machine body with respect to 4), and the lifting cylinder (11) is mounted on the center line in the front-rear direction passing through the position of the center of gravity of the reaper (8). The lifting cylinder (11) is located between the cutting input pulleys (37), the main beam (34) is separated from the cutting belt (40), and the lifting cylinder (1) is moved.
The reaper (8) is configured to support the position of the center of gravity by 1).
