Abstract
PURPOSE: To facilitate change-over operations by providing a change-over switch to change the second speed-change mechanism near a grip of the main speed change control lever.
CONSTITUTION: When the main speed change control lever 19 is changed over, rotation power of an input gear 3 is transmitted through a gear 7 to a counter shift 6, and transmitted to a change shaft 8 after changing its speed by engaging a gear 12 or 13 with the main speed change gear 9. An electromagnetic change-over valve is changed over by operating an actuator 28a of a change-over switch 28 which is provided on a grip 19a of the main speed change control lever 19, the second speed change gear 11 comes to be engaged with a tooth part 15a or 15b of a gear 15, with movements of a shifter piston 25 to the left or to the right, and rotation power of the change shaft 8 is further changed at its speeds by this second speed change mechanism 31, to drive the rotary motion of a drive pinion shaft 5.
