    • PURPOSE: To absorb characteristic difference due to a working error of each valve so as to maintain straight forward traveling capability by forming both interconnecting paths so that they are interconnected only when both right and left directional control valves are full-stroked in the same direction. CONSTITUTION: When directional control valves 4 and 5 are switched over from a neutral position to positions 4c and 5c after full stroke in the same direction, an interconnecting path 13 is interconnected. Also, when the flow of a traveling motor 3 exceeds the flow of a traveling motor 2, a part of the flow to the traveling motor 3 flows to path on the upstream side of the traveling motor 2 through the interconnecting path 13 so as to equalize the flow to the traveling motors 2 and 3 for prevention of curved traveling. Because the interconnecting paths 13 and 14 are interconnected on the downstream side from the directional control valves 4 and 5 and pressure compensating valves 6 and 7, a difference in flow caused by working error not only between the directional control valves but also between the pressure compensating valves 6 and 7 can be also compensated.

    • PURPOSE:To obtain an all-wheel drive type working vehicle capable of steering the front wheels and also of being turned quickly by using a system in which at the same time as the clutches of left and right-handed rear wheels are switched, the brake of the rear wheels is operated. CONSTITUTION:Power from an engine 7 is transmitted through transmission belts 9a and 9b to a front wheel differential 15 to allow the rear wheels 2 to be driven freely. The front wheels 1 are also allowed to be steered freely by a steering link 27 by means of the rotation of a steering wheel. A clutch 17a is provided in the power transmitter from the rear wheel differential 15 to each rear wheel 2. The clutch 17a is switched by stepping in the clutch pedal 22, and the brake 18 of each rear wheel 2 is operated through a sleeve 23. Safe quick turning is made possible by stopping the drive of the freely steering front wheels and rear wheels on the turning side and by operating the brake.

    • PURPOSE:To permit to turn with a small radius of turning by a method wherein a speed increasing mechanism, increasing the peripheral speed of front wheels to 1.5 times of the same of rear wheels when a running speed is low and the operating angle of steering for the front wheels has become more than a preset value, is operated. CONSTITUTION:The power of an engine 5 is transmitted from a speed change mechanism 11, consisting of main and sub speed change mechanisms 9, 10, to a rear wheel differential mechanism 13 through a main clutch 8, while the output of the speed change mechanism 11 is transmitted to a front wheel differential mechanism 18 through a transmitting shaft 15 and the speed increasing mechanism 16. The speed increasing mechanism 16, increasing the average peripheral speed of the front wheel 1-1.5 times of the same speed of the rear wheel, is provided. The speed increasing mechanism 16 is constituted so as to obtain a standard condition, in which the front wheel 1 is driven with the average peripheral speed somewhat higher than the same speed of the rear wheel 2 upon connecting first hydraulic clutch 26, and a double speed condition, in which the front wheel 1 is driven with the average peripheral speed higher than two times of the same speed of the rear wheel 2. Respective clutches 26, 27 are controlled by a control unit so as to be switched to the double speed side automatically upon turning on the end of a cultivating field.
