<p><P>PROBLEM TO BE SOLVED: To obtain an inexpensive seeding transplanter which mechanically automatically raise a planting device when turning. <P>SOLUTION: The seedling transplanter includes: a pitman arm 60 for controlling the direction of a wheel 10 of a traveling vehicle body 2; a planting device provided at the rear side of the traveling vehicle body 2 and lifted by a lifting hydraulic cylinder; a planting lifting lever 33 for lifting the planting device, and for setting the planting; a cam 74 for controlling the lifting hydraulic cylinder in accordance with the operation of the lifting lever 33; a positioning roller 77; link members 61, 62, 64, 71 connected with the pitman arm 60; and a turning switch operation tool 73 connected with the link members 61, 62, 64, 71. The turning switch operation tool 73 can select between a mode for raising the planting device 52 by mechanically driving the cam 74, the roller 77, or the like when a steering member rotates for not less than a predetermined amount and a mode not for driving the cam 74, the roller 77, or the like even when the steering member rotates for not less than the predetermined amount. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
