摘要： PURPOSE:To reduce load of operators in the case of forming holes for inserting bulbs at prescribed intervals in a farmland. CONSTITUTION:A hydraulic cylinder 11 for switching to travelling mode switches a pedal 10 for disconnecting a clutch to the clutch disconnecting side and simultaneously, a hydraulic cylinder 17 for operation of an operating machine 12 is contracted. When control is started, first, the cylinder 17 is stretched and a hole H is bored in a farmland G by a boring rod 20. Then, the cylinder is contracted. When this contraction state is detected by a limit switch 26, the hydraulic cylinder 11 for switching to travelling mode switches the pedal 10 to the clutch-disconnecting side to travel a tractor 1. When it is detected to travel by prescribed distance by a travelling distance detecting means 28, the cylinder 11 switches the pedal 10 to the clutch-disconnecting side to stop the tractor 1. Then, the above-action is repeated.

摘要： PURPOSE:To prevent the operation of a working machine by mistake during the running operation of a tractor. CONSTITUTION:A detection means 8 consisting of a limit switch is placed opposite to a clutch-operation pedal 10 connected to a clutch 3 of a tractor 1. The detection means 8 and a work-operation switch 29 of a working machine 12 are connected to an electrical control board 30. When the pedal 10 is operated to the declutching side, the declutched state is detected by the above detection means 8 to judge that the tractor 1 is in stopped state. Following the above actions, a hydraulic cylinder 17 of the working machine 12 is extended by the electrical control board 30 when the work-operation switch 29 is operated to the operation side. In contrast to the above, when the pedal 10 is operated to the coupling side, the coupled state of the clutch is detected by the detection means 8 to judge that the tractor 1 is in running state. In this case, the hydraulic cylinder 17 is not extended by the electrical control board 30 even by operating the above work-operation switch 29 to the operation side.

摘要： PURPOSE:To uniform intervals of formed holes in the case of making a great number of holes for inserting bulbs by extending an operating hydraulic cylinder attached to a tractor in an agricultural land. CONSTITUTION:A working tool 17 is raised and dropped by an operating hydraulic cylinder 14 attached to the rear part of a body 2 of a tractor 1. A positioning block 19 is raised and dropped by a locating hydraulic cylinder 21 fixed to the side of the body 2 of the tractor. Two positioning tools 22, 23 are longitudinally laid on the under surface of the block 19. In hole making operation, an operator of the tractor 1, first, extends both the cylinders 14, 21 to form two locating holes J, K and a hole H for inserting a bulb in an agricultural land G. Then both the cylinders 14 k 21 are raised, successively the tractor 1 is advanced. When the rear positioning tool 23 is coming near the front hole J, the advance is stopped to extend both the cylinders 14, 21.

摘要： PURPOSE:To improve rooting of a bulb which is placed in a planting hole. CONSTITUTION:In a tractor 1, an oil-pressure cylinder 7 is placed at the rear side of the vehicle 2 and a lifting member 12 is placed at the lower part of a piston rod 11 of the oil-pressure cylinder 7. The lifting member 12 supports plural boring devices 16 on it in such a manner as to be rotatable around their axes. For boring the soil S of a field G, the boring devices 16 are rotated by a rotation-driving means 18 at a specified rotation speed and at the same time the lifting member 12 is lowered by the oil-pressure cylinder 7. Boring members 21 of the boring device 16 bore the soil S and at the same time the bored soil is scraped out from the holes. Plural holes having a specified depth are formed in the soil S by the operation. After forming the holes, the lifting member 12 is lifted by the oil-pressure cylinder 7.

摘要： PROBLEM TO BE SOLVED: To reverse the operating direction of an actuator of a separate working device by the independent operation of the separate working device and operate the actuator of the separate working device stably even though the flow of oil pressure from a working vehicle is fluctuated. SOLUTION: A separate work hydraulic circuit 1 of a mowing device is connected in a detachable state to a pressure oil feed/discharge connection part 3 branching off from a main work hydraulic circuit 2 of a working vehicle. In the separate work hydraulic circuit 1, pressure oil from the working vehicle is regulated to the set flow by a flow control valve 5 and then fed to a hydraulic motor 4 through a direction switching valve 6. The feed/discharge direction of oil pressure to the hydraulic motor 4 is reversed by operating the direction switching valve 6.
