In addition, as different structures, can also make following structure,, in left and right, one side's connecting rod 20 arranges telescopic driver etc., setting makes the upper-lower position different roll drive device 87 forcibly of the wheel 5 of left and right, the ticker 88 of the posture that tilts that detects body is set, and the action based on this ticker 88 and control roll drive device 87, so that the posture that tilts of body is desirable posture., in the rolling of body is controlled now, make following structure,, because concavo-convex strong farmland etc. produces while shaking, can be fixed as ticker 88 not swing to the left and right, do not make roll drive device 87 work.If made by making the friction plates such as rubber slab 89 carry out the fixing structure of this ticker 88 from the bottom surface of downside rising contact vibration 88, even also fixing ticker 88 under the state swinging a little to the left and right at ticker 88, fixedly becoming of ticker 88 is easy.In the past, because be inserts steady pin etc. to fix ticker on ticker, therefore need to make ticker consistent with fixed position after insertion steady pin, fixing of ticker also has difficulties.
In addition, in said structure, represented by between the seedling carrying base of left and right 11 between left and right every being set as the width identical with the left and right width that carries the 11a of seedling portion (carrying one times of width of the left and right width of the 11a of seedling portion), the plantation line-spacing of left and right central authorities is set as to 50cm, the plantation line-spacing of left and right sidepiece is set as to the example of 25cm, but for example also can by between the seedling carrying base of left and right 11 between left and right every the double-width that is set as carrying the left and right width of the 11a of seedling portion, the plantation line-spacing of left and right central authorities is set as to 75cm, the plantation line-spacing of left and right sidepiece is set as to 25cm etc., by between the seedling carrying base of left and right 11 between left and right every many times of width that are set as carrying the left and right width of the 11a of seedling portion, the plantation line-spacing of left and right central authorities is set as to the more than three times of plantation line-spacing of left and right sidepiece.Can make thus central plantation line-spacing become enough broad.
