摘要： PROBLEM TO BE SOLVED: To simplify the control circuit of a hydraulic actuator in configuration for elevating/lowering and driving respective mowers by means of the hydraulic actuator by arranging the respective mowers in the front part and the both left and right parts of a travelling vehicle. SOLUTION: A system is constituted of a hydraulic system for controlling the foreward/backward rotation driving of the left and right mowers 26L and 26R simultaneously or independently, the hydraulic system for executing the foreward/backward rotation driving control and the elevating/lowering control of the front part mowers 22L, 22N and 22R and the hydraulic system for executing the elevating/lowering control of the left and right mowers 25L and 26R respectively. The system is also constituted so as to execute the start/stop change-over of the respective hydraulic systems by two-line valves V1, V2, V3 and V4. The elevating/lowering of the mowers 26L, 26R, 22L, 22H and 22R is executed by a hydraulic cylinder 43 so as to provide connection with a hydraulic circuit which is branched from the middle of a duct for executing communication between the hydraulic cylinder 43 and an elevating/lowering change-over valve and is provided with setting pressure from the branch duct with the change-over valve.

摘要： PROBLEM TO BE SOLVED: To provide an operation machine which can have the swing angle of a sled and the elevation position of a protector properly adjusted according to the height of grass and facilitates the adjusting operation. SOLUTION: In the operation machine 3 which is supported in front of a traveling vehicle body 1 through an operation machine support arm 75 and elevated by a cylinder 79 for operation machine elevation, a hammer knife 67 which cuts grass is supported rotatably. On the reverse surface of the operation machine 3, the sled 71 is supported so that it freely swings up and down around a pin 122, and before the operation machine cover 65 of the operation machine 3, a movable protector 69 is supported so that it is freely elevated around a pin 125. When the front-rear swing angle of the sled 71 is varied with a bolt 124 so as to adjust the height D2 of the lowest point of the hammer knife 67, the movable protector 69 that an abutting member 127 is made to abut against is lowered onto the top surface of the front part of the sled and the gap H2 from the ground surface is automatically adjusted.

摘要： PURPOSE:To provide the subject device having excellent working efficiency and safety and free from trouble of excessive lowering of a mowing unit by setting a limit switch in a stage adjustable in longitudinal direction of the machine body and integrating the limit switch into a circuit at the side to lower the mowing height of a mowing height-adjusting switch. CONSTITUTION:In this device, a limit switch S2 is set just below a sliding path of a mowing height-indicating board 13 at a position adjustable along the longitudinal direction T of the machine body and the limit switch S2 is integrated into the circuit of the side lowering a mowing height in a mowing height- adjusting switch S1. A rod 4a of an elevating cylinder 4 is pulled back by the operation of the mowing height-adjusting switch S1 to lower the lifted mowing unit. At that instant, the action of the elevating cylinder 4 is stopped by pressing a detecting part of the limit switch S2 with the mowing height-indicating board 13 and a lowering end position of the detecting unit is automatically decided.
