PROBLEM TO BE SOLVED: To accommodate to both cases of using a conventional-type seedling-raising seedling mat and using a highly-dense seedling-raising seedling mat in which seedlings are highly densely raised more than the conventional-type seedling-raising seedling mat.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, and is configured to be able to change the number of times of transverse feed, as the number of times when the planting claw 30 rakes a seedling from the seedling mat, while the seedling tray 29 is transversely fed to any of left/right moving end. The number of times of the transverse feed in a case of using a conventional-type seedling-raising seedling mat is differentiated from that in the case of using a highly-dense seedling-raising seedling mat in which seedlings are highly densely raised more than the conventional-type seedling-raising seedling mat. When using the highly-dense seedling-raising seedling mat, the number of times of the transverse feed is increased more than that when using the conventional-type seedling-raising seedling mat.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2017,JPO&INPIT【課題】苗植え作業において、従来型育苗の苗マットを用いる場合と、従来型育苗の苗マットよりも苗が高密度に生育された高密度育苗の苗マットを用いる場合の両方に対処できるようにする。【解決手段】本願発明の田植機1は、左右に往復移動する苗載台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、苗載台29を左右いずれかの移動端まで横送りする間に植付爪30が苗マットから苗を掻き取る回数である横送り回数を変更可能に構成している。従来型育苗の苗マットを用いる場合と、従来型育苗の苗マットよりも苗が高密度に生育された高密度育苗の苗マットを用いる場合とで、横送り回数を異ならせると共に、高密度育苗の苗マットを用いる場合には、従来型育苗の苗マットを用いる場合に比べて、横送り回数を多くする。【選択図】図9
