DIFF-LOCK OPERATING MECHANISM OF PADDY FIELD WORKING MACHINE

摘要

PURPOSE:To provide a diff-lock operation mechanism, with which the planted condition of an extra-soft water field can be enhanced through lessening of slip of driving wheels in high speed planting work, and with which movement and running can be done without braking phenomenon associate with running-off from damp place or head swinging. CONSTITUTION:A diff-lock engaging means A actuates a diff-lock device 3 when the difference in the revolving speed between the left and right driving wheels 2L, 2R has exceeded the set value set previously by a setting device 6 which is adjustable any as desired, while a shift engaging means B generates engagement of a transmission 10 with the setting device 6 so that the set value is enlarged with changing-over of the transmission 10 for the driving wheels 2L, 2R to the high speed side and is lessened with changing-over into the low speed side.
