摘要： PURPOSE:To provide a mower of improved accuracy and of simplified structure in such a manner that an intermediate shaft is advanced through a screw-feed mechanism by an electromotive motor, and a mower is put to vertical motion through a link mechanism, and when the mower is brought to a specified position, the operation of the motor is stopped. CONSTITUTION:(A) The driving shaft 17 of an electromotive motor 15 and (B) an intermediate shaft 19 interlockingly connected, via a link mechanism 18, to a mower 2, are connected via a screw-feed mechanism 20, and the mower 2 is driven for its vertical motion through the screw-advancement of the intermediate shaft 19 associated with the normal-inverse driving rotation of the driving shaft 17. When the mower 2 is displaced to a specified position, limit switches 27a, 27b output the detection signals to a control means 28 to effect stopping the driving of the motor 15.

摘要： PURPOSE:To facilitate the check, maintenance and cleaning of the lawn mower by providing the mower with a mechanism for fixing uprightly the link unconnected from the running body to one end of the mower. CONSTITUTION:When it is fixed uprightly to the rear end of the mower 6, the rear link 6 is swung to the upright posture and a screw having a knob is inserted through the long hole 10 to the tapped hole 9. Then, the rear link 6 is swung backward around the roller 13 beneath the rear link 6 whereby operations such as exchange of blades or the like can be easily done.

摘要： PURPOSE:To simply and surely conduct the vibration proof support of a radiator by providing standingly through vibration proof elastic bodies a radiator which is to be provided within an engine room, and at the same time, supporting push-pressingly the upper end of the radiator with the internal surface of a bonnet through, likewise, vibration proof elastic bodies. CONSTITUTION:A work vehicle, for example, a tractor is provided, within an engine formed so as to be openable/closable by means of a bonnet 4 whose front end side is pivotingly supported, with a radiator 7 so that an engine cooling wind may be discharged from an operation portion side to the front. In this instance, a pair of support legs 2 projectingly provided at the right and left of the lower end portion of the radiator 7 are inserted into the holes of ringlike vibration proof rubbers 1 put on a car body frame 18, and thus, the radiator 7 is supported in vibration proof and standingly provided. And presser projections of rubber 19 are provided at the right and left of the upper end portion of the radiator 7, and thus, pressor projections 19 are push-pressed with the internal surface of the bonnet 4 at the time of the closure of the bonnet 4, and the sidelong shaking of the radiator 7 is prevented.
