<P>PROBLEM TO BE SOLVED: To provide a rice transplanter including a compact root interval adjusting mechanism capable of freely setting intervals between roots and adjusting gear shift between roots. <P>SOLUTION: A transmission input axis 41 of a transmission 40 includes a travelling power transmission system A for transmitting the power to travelling wheels 2 and 3, a planting power transmission system B for transmitting the power to a planting part 12, and a power dividing part 49 for dividing the power from an engine 7. The power dividing part 49 includes a planting system power dividing gear 51 to be engaged with a gear 62 of a planting first shaft 61 adjacent to the transmission input axis 41 for dividing the power to the planting power transmission system B. The planting first shaft 61 includes a friction wheel type infinite variable-speed drive 20 for shifting gears between a planting first shaft 61a on the input side and a planting first shaft 61b on the output side which are disposed on the same axis. The infinite variable-speed drive 20 shifts gears for the power input to the planting part 12 to set the intervals between roots and shift the speed in the planting part 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
