<P>PROBLEM TO BE SOLVED: To solve trouble that the cut cross section of a head forming vegetable A is disturbed caused by the low speed rotation of a drive cutter 61 when a travelling machine body 2 travels at low speed in a head forming vegetable harvester 1. <P>SOLUTION: The head forming vegetable harvester 1 includes a harvest operation part 13 for pulling the head forming vegetable A in front of the travelling machine body 2 and conveying the same backward, a drive cutter 61 for cutting the rootstock A2 of the head forming vegetable A conveyed in the harvest operation part 13 and a rotary actuator 64 for rotatively driving the drive cutter 61 independently without synchronizing the vehicle speed of the travelling machine body 2. In this case, the drive cutter 61 can rotate in high speed by the rotary actuator 64, in spite of the vehicle speed, fast or slow, of the travelling machine body 2, to remove false cutting of the head forming vegetable A. <P>COPYRIGHT: (C)2013,JPO&INPIT |
