Abstract

PURPOSE: To accomplish low speed-high load and high speed-low load runnings easily by a method wherein a hydraulic pump is provided repectively for each hydraulic motor which drives front and rear wheels separately.
CONSTITUTION: In order to apply the said device to an agricultural tractor, two hydraulic motors M1, M2, which drive right and left front wheels 1, 2 respectively, are provided in the supply oil circulating route 3 of the 1st variable capacity pump P1 driven by an engine E and the 1st change-over valve 4 is provided between both motors M1, M2 so that the 1st operating position that connects them in series can be changed over with the 2nd operating position that connects them in parallel. On the other hand, two hydraulic motors M3, M4, which drive right and left rear wheels 6, 7 respectively, are provided in the supply oil circulating route 8 of the 2nd variable capacity pump P2 and the 2nd change-over valve 9 as stated above is provided between both motors M3, M4. And near the inlet or outlet of the pump P1 is provided the 3rd change-over valve 11 that can change the pump P1 by a lever into the route 3 or 8.
