Claims

[Claims for Utility Model Registration] ■ Cylinder 15° 15 that separately drives up and down the ground running parts of the left and right traveling devices 1.1 with respect to this machine A, and drives the reaping part 7 up and down with respect to this machine A. In the reaping machine, pressure fluid can be selectively supplied to the traveling device lifting cylinder 15.15 on the downstream side in the pressure fluid supply direction of the lifting switching valve 16 for the reaping unit lifting cylinder 6. A reaping machine characterized by having a valve 17 interposed therein. (2) A state in which the selective supply valve 17 allows pressure fluid to be supplied and discharged to one traveling device lifting cylinder 15, a state in which it allows pressure fluid pressure to be supplied and discharged to the other traveling device lifting cylinder 15, and both cylinders 15; .15 and a state that allows pressure fluid to be supplied and discharged from the cylinder 6 for raising and lowering the reaping section. Claim 0 of the Utility Model Registration Claim: Reaper described in. (2) The reaping machine according to claim 0 or (i) of the utility model registration claim, wherein the traveling devices 1, 1 are of a crawler type.
