摘要： PROBLEM TO BE SOLVED: To enable the transmission of power even in the case where a change gear system is in a neutral position in a transmission system in which power is transmitted from the downstream side of a transmission of the change gear system having a hydraulic clutch to a seedling-planting apparatus. SOLUTION: A working vehicle is provided with an advance-and-retreat change gear apparatus D composed of a hydraulic clutch 38 which is freely shifted into an advance position F, a neutral position N or a retreat position R, and a control valve 50 which cuts the hydraulic clutch 28 at the start of the operation of a shifting member 47, inputs it at the end of the operation and keeps it in a cut state in the neutral position N. On the working vehicle, a transmission system for transmitting the power synchronized to a mobile speed at the downstream side of transmission of the hydraulic clutch 28 to a seedling-planting apparatus is formed, and a supplementary valve 58 for feeding a pressure oil to the hydraulic clutch 28, in order to input the hydraulic clutch 28 in a state where the shafting member 47 is in the neutral position N, is attached.

摘要： PURPOSE: To provide the subject relatively lightweight speed change operational device capable of conducting a change-over operation for advance/retreat at low cost so as to be applicable even to an inexpensive kind of machines, designed to reasonably link to the forced raising actuation of a working device as a result of retreat. CONSTITUTION: This speed change operational device is equipped with a synchronous-type advance/retreat change-over mechanism and a hydraulic clutch on the transmission upper side thereof and is so designed that the spool 17 of a clutch control valve is externally engaged with a shift fork and a change- over lever 40 is interlocked therewith. The spool 17 and the shift fork are mutually interlockingly linked so that the hydraulic clutch is temporarily let out as the advance/retreat change-over mechanism is transferred from one party to another among the advance and retreat positions F, R and neutral position N, and a flexibility is afforded so that the hydraulic clutch is let out prior to shift initiation. A hydraulic oil fed to the hydraulic clutch as a result of the retreating operation of the advance/retreat change-over mechanism is guided to a lift hydraulic cylinder 8 to rapidly raise a planting device.

摘要： PROBLEM TO BE SOLVED: To provide a marker apparatus for a paddy field implement, with which an index by banking is surely and readily formed even in the case of soft mud in a field. SOLUTION: A rotary marker body 25 is supported on a marker arm part 23b at the tip of a marker arm 23 so that the rotary marker body can be grounded and rotated. A soil raising tine 29 is peripherally arranged on the outer peripheral part of the rotary marker body 25. With the grounding and rotation of the rotary marker body 25, the soil raising tine 29 raises soil from a mud part and drops on a mud surface to give an index. A marker arm part 23b at the tip side is equipped with a fixed resistance plate 31 and a projected part 32 furnished with the rotary marker body 25 in a state to be engaged with and disengaged from the recessed part 34 of the resistance plate 31 to constitute a resistance imparting means 30. The resistance imparting means 30 changes the rotation resistance in the grounding and rotation of the rotary marker body 25 by rotation position. COPYRIGHT: (C)2003,JPO
