APPARATUS FOR OPERATING SPEED CHANGE OF POWER TILLER

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for operating the speed change of a power tiller capable of taking the traveling speed and tillage speed in many stages without directly rotating a rotary at a low speed and a middle speed. SOLUTION: This apparatus for operating the speed change is obtained by composing one speed change lever freely shaking with a shaft supporting part as the center so that the speed change lever can be engaged so as to freely change over from a speed change fork shaft at the high speed traveling speed and backing side to a speed change fork shaft at the low speed and middle speed traveling speed and interposingly arranging an interlocking mechanism between the shaft supporting part and the rotary fork shaft so that the rotary fork shaft is freely changed over to the clutch disengaged side when the speed change lever is engaged with the speed change fork shaft on the high speed traveling speed and backing side and to the clutch disengaged side or clutch engaged side when the speed change lever is engaged with the speed change fork shaft at the low speed and middle speed traveling speed, composing a speed change guide of the speed change lever of an H-type guide groove so as to communicate between a changeover groove of the low speed and middle speed and a changeover groove of the high speed and backing with a neutral groove and notching a site corresponding to the neutral groove of the interlocking mechanism.
