摘要： PURPOSE:To arrange both transmission systems from an engine to a transmission case in the compact state so as to facilitate the inspection/replacement of the transmission system especially from the engine to the PTO transmission system in the transmission structure of a vehicle with an engine and a transmission case, provided with both PTO transmission system and travel transmission system, disposed side by side. CONSTITUTION:A hydrostatic pressure type continuously variable transmission 12 for travel is provided on the side face, on the engine 2 side, of a transmission case 1. The input shaft 13 of this hydrostatic pressure type continuously variable transmission 12 is protruded onto the engine 2 side, and the input shaft 16 of a PTO transmission system is protruded onto the engine 2 side, from the same side face but in a different position from the hydrostatic pressure type continuously variable transmission 12. A first transmission belt 15 is wound across the first output pulley, on the engine 2 side, of the output shaft 9 of the engine 2, and the input pulley 14 of the hydrostatic pressure type continuously variable transmission 12. A second transmission belt 18 is wound around the second output pulley 11, on the transmission case 1 side, of the output shaft 9, and the input pulley 17 of the PTO transmission system.

摘要： PURPOSE:To enable safe travel without laterally turning even by recovering a large amount of lawn by equipping the back of a machine body with a recovering device straddling a driving part and extending the lower end of the recovering device to the vicinity of the ground surface. CONSTITUTION:The front of a mobile machine body is equipped with a lawn mower and its back is provided with a driving part 20 and a recovering device 3 for cut lawn. The recovering device 3 is equipped with a nearly OMEGA-shaped supporting frame 17 straddling the driving part 20 and two recovering containers 13 and 13, insertable and removable from the left and right on both sides. The cut lawn is then contained through a duct 11 in the containers. The left and right lower ends (17a) and (17b) of the supporting frame 17 are set near the ground surface and the machine body is prevented from lateral turning by ground contact even if it is about to laterally turn.

摘要： PURPOSE:o provide a simple structure and cost reduction by installing a lower part frame which connects the lower part of a transmission case hung from the other end of a main frame and the main frame, and mounting and supporting an engine for the transmission case. CONSTITUTION:Both front ends of a pair main frames 8, 8 are connected by a front transverse frame 10, and a transmission case 5 is hung from it by bolting. The front parts of a pair of right and left supporting frames 11, 11 are connected to the lower part of the transmission case 5 by bolting, and a pipe frame 12 of U-shape from front view which connects rear ends of the supporting frames 11, 11 is connected to rear frames 7, 7 respectively by bolting. An engine is mounted on a lower frame 9 which consists of the pipe frame 12 and both the supporting frames 11, 11 to transmit driving force of the engine to a running transmission through an HST. The steering wheel of a maneuvering part and a floor frame which supports a step are connected to the transmission case 5 by bolting.

摘要： PURPOSE:To increase controllability by providing the second pedal at a position adjacent to the first pedal, interlocked and connected to a speed changing part, free to swing around the pivot shaft intersected at right angle with the pivot shaft of the first pedal, and enabling the pushing up operation of the first pedal by depressing the second pedal through an arm. CONSTITUTION:A first pedal 9 is mounted free to swing around the axis P1 positioned on the floor panel 8 of a work vehicle such as passenger type lawn mower in the transverse direction, and the speed changing part 7a of a HST 7 (hydraulic stepless transmission) is interlocked and connected to the first pedal 9 through rods 10 and 11 and a bell crank 12. Also, a second pedal 13 is mounted on the right side of the first pedal free to swing around the axis P2 positioned in the longitudinal direction of the vehicle, and an arm 14 located to come under the first pedal 9 is fixed onto the back of the second pedal 13. When the second pedal 13 is depressed, the first pedal 9 may be pushed up through the arm 14. Thus, the speed changing operation part 7a is operated to increase the speed in the reverse side.

摘要： PURPOSE:To reduce the shaking of the machine body and design the structure so that a device for transmission of the power to rear wheels may rarely come into contact with a projection on the ground, e.g. a rock or a stump in a riding lawn mower in which the axle case of the rear wheels is installed to a mobile machine body so as to be supported freely rotatable around the back-and-force axis. CONSTITUTION:The rolling axis X of rear wheels is set in the neighborhood of the lower surface of the car body frame (a) higher than the axle case (4a) of the rear wheels. In addition, this riding lawn mower is designed so that the power may be transmitted from a running mission case (M) at the front part of the machine body through a transmission shaft 7 arranged along the neighborhood of the under surface of the car body frame (a), a joint shaft 8 and a transmission gear in a vertical auxiliary transmission case 9 to the rear wheels 4.

摘要： PURPOSE:To provide a front mower riding type lawn mover having a low weight center and an excellent small turning property by adopting a seasonable frame structure. CONSTITUTION:A grass-collecting container 27 is disposed at the rear part of a front mower riding type lawn mower having driving front wheels 3 and steering rear wheels 4 capable of being steered about a single longitudinal shaft. A pair of lateral main frames 8,8 are formed in a stepped state in which the rear part of the frame is lower than the front part of the frame. An engine E is suspended through a lower frame 9 below the main frames 8 between the front and rear wheels 3,4, and a fuel tank T is mounted on the rear part of the main frame 8. An air cleaner 22 and the water-supplying opening 26 of a radiator are received in a rear bonnet.
