Abstract: A mower with a grass catcher (10) for collecting grass clippings transmitted from a mower unit. The grass catcher has an inlet opening (12) in a front position thereof, and an outlet opening (13) and an openable lid (14) in a rear position. The grass catcher (10) is connected to the rear end of a vehicle body to be supported in a suspended state by a grass catcher support unit (100). The support unit includes mounting posts (9) attached to the rear end of the vehicle body and extending upward, and a support link mechanism (20) for interconnecting upper regions of the mounting posts and lower rearward regions of the grass catcher, and for switching the grass catcher between a grass clippings collecting posture with the inlet opening directed forwardly of the vehicle body, and a raised dumping posture with the outlet opening directed downward. The support link mechanism performs a switching process for switching the grass catcher from the grass clippings collecting posture to the raised dumping posture.

Abstract: A working vehicle having a propelling transmission for transmitting power of an engine drive wheels, the propelling transmission being attached to body frames as offset to one side transversely of a vehicle body to produce a utility space in the other side, with a PTO apparatus for transmitting power supplied from the propelling transmission to an external working implement. The PTO apparatus includes an input shaft extending longitudinally of the vehicle body and drivably connected to the propelling transmission, and an output shaft extending parallel to and spaced from the input shaft and drivingly connected to the external working implement. A mounting mechanism system is provided to attach the PTO apparatus to vehicle body frames. The mounting mechanism system selectivety fixes the PTO apparatus in at least two pivotal postures about the input shaft.

Abstract: A riding lawn mower includes a front wheel unit (1), a rear wheel unit (2) having a left rear wheel (2a) and a right rear wheel (2b), a body frame (3) supported by the front wheel unit and rear wheel unit, a mower unit (10) disposed under the body frame between the front wheel unit and rear wheel unit, a driver's seat (5) disposed on the body frame to be above the mower unit, an engine (7) disposed rearwardly of the driver's seat, and a drive transmission mechanism (70) for transmitting drive from the engine to the rear wheel unit. The engine (7) is disposed between and substantially at a higher level than the left and right rear wheels (2a, 2b) to secure a utility space (100) extending longitudinally of the vehicle body between the left and right rear wheels.

The PTO apparatus (40) includes an input shaft (42) extending longitudinally of the vehicle body and drivably connected to the propelling transmission, and an output shaft (43) extending parallel to and spaced from the input shaft and drivingly connected to the external working implement. A mounting mechanism (30; 50) is provided to attach the PTO apparatus to vehicle body frames (8). The mounting mechanism selectively fixes the PTO apparatus to at least two pivotal postures about the input shaft.

Abstract: A frame structure for connecting working implements to a vehicle body having right and left main frames extending parallel to each other longitudinally of the vehicle body. The main frames are divided into upper front frames and lower rear frames which are interconnected through an intermediate connecting section. The front and rear frames have different heights to lower the center of gravity of the rear section of the vehicle body for promoting stability of vehicle control without impairing the steering function of front wheels. A cross support member is connected to bottom surfaces of the main frames in the region of the intermediate connecting section. This support member has opposite ends thereof extending laterally outwardly of the main frames. Outward extension of the cross support member include connecting elements for working implements. These connecting elements and the front frames are used as supporting connections for connecting working implements such as a front loader and a mower unit.

Abstract: A speed control system for a working vehicle comprises a hydrostatic transmission for propelling the vehicle, a hydraulic cylinder and a control valve. The hydraulic cylinder includes a cylinder case operatively connected to a control shaft for varying a swash plate angle of the hydrostatic transmission, and a piston rod fixed to a case containing the hydrostatic transmission. The control valve is fixed to the cylinder case and includes a spool extending parallel to the hydraulic cylinder and operatively connected to a foot pedal for manually controlling the hydrostatic transmission. The cylinder case is shiftable following a shift of the valve spool.

Abstract: An agricultural tractor in which a transmission case comprises a front case portion housing a hydraulic stepless change speed mechanism and a rear case portion housing a gear mechanism. A partition wall is interposed between the front and rear case portions, and a tractor frame is secured to the partition wall by means of bolts.

Abstract: A running apparatus for an agricultural vehicle comprising an oil stepless change speed device, an oil circuit for an oil pump and an oil motor to actuate the oil stepless change speed device and an accumulator. The accumulator accumulates a surplus of an output pressure of the oil pump when the pressure is higher than a predetermined value and discharges the accumulated pressure when the output pressure of the oil pump is lower than the predetermined value.

Abstract: A change speed operating apparatus for a tractor comprises an oil hydraulic stepless change speed device, a change speed pedal for operating the device, a change speed operating mechanism for connecting both of the device and the pedal, a neutral return mechanism for urging the change speed operating mechanism into a neutral position, a speed setting mechanism and permissible means for permitting an independent movement of the change speed operating mechanism in a direction of acceleration to forward traveling.
