ク手段４５により完全にロックすれば良く、これで各ゲ
ージ輪２８．３３の上下調整が完了する。After the front gauge wheel 28 and the rear gauge wheel 33 have been moved up and down to the required positions by operating the operating lever 39 back and forth in this manner, the engaging pawl 48 is inserted into the engaging recess 47 of the guide plate 40 at the operating lever 39 position. Once engaged, the operating lever 39 is completely locked by the locking means 45, and the vertical adjustment of each gauge wheel 28, 33 is completed.
この場合、すべてのゲージ輪２８，３３を１本の操作レ
バー３９で簡単且つ任意に上下調整できるので、作業途
中で刈高さを変更する際等には非常に効果的である。In this case, all the gauge wheels 28, 33 can be easily and arbitrarily adjusted up and down with one operating lever 39, which is very effective when changing the cutting height during work.
刈取作業時には、油圧シリンダ２７を伸縮自在な自由状

ながら、トラクタ車体１を走行させる。During reaping work, the hydraulic cylinder 27 is set in a freely expandable and retractable state, and the entire mower 10 is lowered so that the front gauge wheel 28 and the rear gauge wheel 33 are in contact with the ground. The tractor body 1 is run while rotating the body 12 in the direction of arrow e.
すると各屈折リンク機構１９が自在に屈伸動作をするの
で、モアー１０は地面に確実に追従して昇降し、各刈刃
体１２により芝生等を一定の刈高さで゛刈取ることかで
゛きる。Then, each bending link mechanism 19 freely bends and stretches, so the mower 10 moves up and down while reliably following the ground, allowing each cutting blade body 12 to mow the lawn or the like at a constant cutting height. Wear.
モアー１０を持上げる場合は、油圧シリンダ２７を収縮
動作させると、各屈折リンク機構１９が同一量だけ屈折
してモア一本体１１は直線的に上昇する。When lifting the mower 10, when the hydraulic cylinder 27 is retracted, each bending link mechanism 19 bends by the same amount, and the mower main body 11 rises linearly.
作業機はミツドマウントモアーに限定されるものではな
い。The working machine is not limited to the midmount mower.
