COUPLING DEVICE OF MOWER COLLECTOR

PROBLEM TO BE SOLVED: To solve a problem that attaching/detaching operation is complicated, cumbersome, and requires a long time because a plurality of pins, hooks are fitted or engaged while supporting a heavy collector, the connecting of a dump cylinder for dumping and operating the collector and the connecting of hydraulic hoses of the dump cylinder are carried out when attaching and detaching the mower collector to a rear part of a vehicle body.SOLUTION: A hitch bracket 7 and the dump cylinder 8 are arranged in the rear part of the vehicle body 2, pin holes 12, 13 through which the connecting pin 11 can be passed from a lateral side are formed in a bracket arm 9 above the hitch bracket 7 and in a hitch arm 10 above the opening part 6 of the collector 5, the connecting 11 is passed through a pin hole 15 of a piston 14 of the dump cylinder 8 and is formed in a bifurcated shape by being integrated with a dump pin 18 capable of being passed through a dump pin hole 16 of the hitch arm 10.
