Abstract

PURPOSE: To enable the tractor to run as a whole smoothly, by allowing the front steered wheels to have a single hydraulic pump common to two motors, and driving the rear wheels by another independent pump and a motor.
CONSTITUTION: The steered wheels 1 as well as the hydraulic motors M1 are supported at lower ends of respective cylinders 8, each set of the wheel 1 and the motor M1 is pivoted swingably about a vertical shaft 9 at the lower end of the cylinder 8, knuckle arms interconnected to the vertical shafts 9 are connected by a tie rod 11, and a drag ros 12 is interconnected with a pitman arm 13 interlocked with a steering handle 3. On the other hand, the rear wheels 2 are driven through a differential mechanism 6, and the differential mechanism 6 and the motor M2 are interlocked through a gear type speed change apparatus 7. Both of the hydraulic motors M1 on the front wheel side are connected to the common hydraulic pump P1 in parallel. The differential mechanism 6 is interlocked with the single hydraulic motor M2 which in turn is connected to a single hydraulic pump P2.
