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