PROBLEM TO BE SOLVED: To provide a harvester with which operation of clutch disengagement is easily performed and when a clutch is disengaged, power transmission to a horizontal conveying part is completely shut off. SOLUTION: A Welsh onion harvester, one example of a harvester, is equipped with a horizontal conveying part for conveying Welsh onions harvested from a field in the horizontal direction and a power transmission mechanism 30 for transmitting power to the horizontal conveying part. The power transmission mechanism 30 is equipped with a rotary supporting part 41 having a third intermediate pulley 42 to be rotated by transmitted power and a planetary reducer 50 is connected to the rotary supporting part 41. The sun gear 51 of the planetary reducer 50 is an input side element and an internal gear is an output side element. The planetary reducer 50 is equipped with a clutch mechanism 70 for disconnecting the transmission of power transmitted to the input side element to the output side element of the planetary reducer 50 by operation. The clutch mechanism 70 is equipped with a serration shaft 71 slidably supported along a serration hole 54a arranged on the first carrier 54 of the planetary reducer 50. COPYRIGHT: (C)2007,JPO&INPIT
