LAWNMOWER
Document Type and Number:
Japanese Patent JP3926243
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a lawnmower in which outputs of a pair of left and right hydrostatic continuously variable transmissions are reduced to be transmitted to a pair of left and right travelling devices respectively through a pari of left and right speed reduction transmission mechanisms while branching driving force from an engine through a transmission case into a pair of left and right hydrostatic continuously variable transmissions, wherein the speed reduction transmission mechanisms can be miniaturized while the continuously variable transmissions and travelling devices are driven at required rotation speed and by driving force of driving torque.
SOLUTION: The hydrostatic continuously variable transmission 40 is configured so as to be driven in a state in which discharging oil amount per rotation of a hydraulic pump 43 is less than that of a hydraulic motor 44 throughout the speed variable range.
