摘要： The present invention provides a simple and compact power transmission mechanism for a tractor or similar vehicle having mounted thereto a mechanical attachment such as a lawn mower. The power transmission mechanism includes an engine which transmits driving power to ground engaging wheels through a driving power transmission unit and to the mechanical attachment through a driving speed changing unit positioned atop the transmission unit and operatively interconnected to the drive shaft thereof. The driving speed changing unit includes an input shaft which receives engine driving power for driving the drive shaft through a differential gear unit. Engine power is transmitted to the attachment through a belt from a power take-off unit coupled to the input shaft.

摘要： A vehicle power transmission for tractors and the like having a fluid operated speed-change mechanism which comprises a plurality of rotatably mounted speed-change gears arranged on a lay shaft and a plurality of fluid actuated clutches associated with the respective speed-change gears for selectively connecting each of the gears to the lay shaft. A brake is provided which selectively brakes the lay shaft at the non-operation state of the fluid operated speed-change mechanism. The brake prevents unexpected transmission of power through the speed-change mechanism at the non-operation state of the mechanism, thereby preventing problems such as an unexpected start of the vehicle.

摘要： An axle driving apparatus which is so constructed that an input pulley for engine power is set lower in mounting position with respect to the axis of a driving axle so s to enable the platform of a vehicle to be lowered. The engine position lowers to promote miniaturization, a lower center of gravity and running stability of the vehicle. For maintenance of the transmission for driving the axle, the entire axle driving apparatus need not be removed from the frame of the vehicle. A bearing for supporting the axle to the casing is held with exact dimensional precision so as not to cause a backlash on the axle, to thereby prolong the life span of the bearing. The axle is ensured to be sealed, the number of mounting bolts for the casing need not be increased in order to improve rigidity, and the casing is strong so that the assembly time for the axle driving apparatus is minimized.

摘要： An axle driving apparatus which houses a hydraulic non-stage transmission in a casing comprised of at least two casing members and coupled by a substantially flat coupling surface formed therebetween. The casing also houses an output shaft of the hydraulic non-stage transmission which is offset in parallel to the coupling surface. This construction allows for simple manufacture and maintenance of the hydraulic non-stage transmission and axles, provides for a smaller downward projection of the casing thereby reducing interference with obstacles on the ground, improves sealing capability of the casing when a braking unit is attached to one axial end of the output shaft, and reliably bears the thrust of the hydraulic motor.

摘要： A first hydraulic pump P1 driven by power of an engine and a first hydraulic motor M1 are fluidly connected so as to form a closed fluid circuit. An output shaft 2 of first hydraulic motor M1 is drivingly connected with a sub-transmission 3. The output power from sub-transmission 3 drives main-driving wheels 5 and also drives a second hydraulic pump P2 fluidly connected with a second hydraulic motor M2 for driving sub-driving wheels 6. A clutch 7 is interposed between an output shaft 4 of sub-transmission 3 and an input shaft 9 of second hydraulic pump P2 or on the output side of second hydraulic motor M2. Second hydraulic pump P2 or second hydraulic motor M2 has variable displacement, so that second hydraulic motor M2 is drivingly accelerated in proportion to the degree of turning operation of a steering operating tool 31. In case that a plurality of front reel mowers 8FL, 8FM and 8FR are disposed in front of the vehicle body, a pair of decelerator casings 29 are disposed on both lateral sides of transmission casing 1 for driving main-driving wheels 5. Decelerator casings 29 project horizontally forward and support main-driving wheels 5 respectively at their front portions. Middle front reel mower 8FM is disposed between left and right decelerator casings 29.
