摘要： PURPOSE:To improve the operability by operating an artificially left and right operable turning member in the back-and-forth direction so as to enable selection of deceleration rotation and reverse rotation, and thereby continuously carrying out the operation from selection of the deceleration rotation and reverse rotation to a rightward/leftward turn operation. CONSTITUTION:The speed of right and left travel devices 1a, 1b when a manually operable member 16 of a transmitter 5 is at each of right and left operation stroke ends is made settable to any given different value between a first speed V lower than a travel speed VN when the operable member 16 is located at a neutral position N as viewed in its horizontal direction and a second speed V2 of the reverse rotation. Further, depending upon the operation position of the operable member 16 as viewed in the back-and-forth direction, the speeds of the right and left travel devices 1a, 1b at the right and left operation stroke ends of the operable member 16 are made selectable from between the speeds V1 and V2. Further, between the travel speed VN and a selected speed at the right or left operation stroke end, the speed of the right or left travel device 1a, 1b is made continuously low, or made elevatable in reverse rotation, so as to become equal to a speed corresponding to the right or left operation position of the operable member 16.

摘要： PURPOSE:To improve straight running ability and drivability by a method wherein a rotation direction is shifted by a running control valve to control the feed and discharge of pressure oil to and from a pair of hydraulic motors for an uneven terrain type running devices on both sides, and a delivery amount of d variable volume type hydraulic pump is varied and an equivalent branch feed is effected by a flow divider. CONSTITUTION:A hydraulic motor M1 is linked to a crawler drive wheel 5a of each of crawler running devices 5 on both sides of a crawler type running device body, e.g. a radio controllable reel type lawn mower. A pair of running control valves (three position switching valve) V1 mounted to respective hydraulic motors M1 through respective feed discharge oil passages 8 are connected to the delivery side of a variable volume type first hydraulic pump P1 through a feed oil passage 8, in which a flow divider 7 is located, and connected to the suction side of the first hydraulic pump P1 through a return oil passage 9. The flow divider 7 branches oil, inputted through an input port 7a, into two equivalent amounts of branch oil, and each branch oil is feedable through each output port 7b to running control valves V1 and V2.
