To provide a movable balance weight device provided on a work vehicle to which, a work unit is coupled so as to oscillate freely in a vertical direction, tows the work unit and performs prescribed work to a farm field, the balance weight device capable of eliminating adjustment of the number of balance weights for each kind of the work unit, a relative position of the work unit to the work vehicle, and capable of sufficiently adjusting so that, front/rear weight distribution as whole vehicle becomes substantially equal, by the small number of balance weights.SOLUTION: There is provided a movable balance weight device 100 which is provided on an opposite side of a work unit 1 side on a work vehicle 1 to which, a work unit 2 performing prescribed work to a farm field, is coupled so as to oscillate vertically freely, the movable balance weight device comprises: a weight part 110 for achieving weight balance with the work unit 2; and a weight displacement mechanism part 120 for displacing the weight part 110 in an approach direction of approaching the work unit 2, and in a separation direction.SELECTED DRAWING: Figure 2

    【課題】上下揺動可能に作業装置を連結し、当該作業装置を牽引しながら圃場に対して所定の作業を施す作業車両に備えられる可動式バランスウエイト装置であって、作業装置の機種や、作業車両に対する作業装置の相対位置ごとに、バランスウエイトの枚数を調整する必要が無く、また少ない枚数のバランスウエイトによって、車両全体としての前後重量配分が略均等になるように十分に調整可能な可動式バランスウエイト装置を提供する。【解決手段】圃場に対して所定の作業を施す作業装置2が上下揺動可能に連結される作業車両1の作業装置1側とは反対側に備えられる可動式バランスウエイト装置100であって、作業装置2との重量バランスをとるためのウエイト部110と、作業装置2に対する近接方向、及び離間方向にウエイト部110を変位させるウエイト変位機構部120とを有する。【選択図】図2
