PROBLEM TO BE SOLVED: To secure a yield, reduce a seedling raising cost, and reduce labor for raising the seedling and carrying the seedling without changing an interspace between the seedlings by an interspace speed-change gear (in a different viewpoint from sparse planting) in seedling planting work.SOLUTION: A rice planter 1 according to the present invention includes a planting claw 30 for raking a seedling for one rice plant from a seedling mat placed on a seedling tray 29 and planting it in a field. A take-out opening cover 226 having an opening groove 231 through which the planting claw 30 passes is detachably attached to a seedling take-out opening 220 of a seedling take-out plate 221 disposed on the lower side of the seedling tray 29, and any of a plurality of types of take-out opening covers 226 having opening grooves 231 with different groove width sizes, is attached to the seedling take-out opening.SELECTED DRAWING: Figure 17COPYRIGHT: (C)2017,JPO&INPIT【課題】苗植え作業において、株間変速装置で株間を変更しなくても(疎植とは別の視点で)、収量の確保、育苗コストの低減並びに育苗・苗運び作業の労力軽減を図る。【解決手段】本願発明の田植機1は、苗載台29に載置された苗マットから1株分の苗を掻き取って圃場へ植え付ける植付爪30を備えている。苗載台29の下方に配置した苗取出板221の苗取出口220に、植付爪30の通過する開口溝231を有する取出口カバー226が着脱可能に取り付けられると共に、開口溝231の溝幅寸法を広狭異ならせた複数種類の取出口カバー226のうちいずれかが苗取出口に取り付けられる。【選択図】図17
