<p><P>PROBLEM TO BE SOLVED: To provide a riding type rice transplanter which can accurately lower a transplanting device at a desired position. <P>SOLUTION: A controller 50 disengages a planting clutch 51 and a side clutch 55 in this order in the first term of a turning time, and engages the side clutch 55 and the planting clutch 51 in this order in the last term of the turning time. An output shaft EO for transmitting a driving force from an engine 12 to a rear wheel 17 is disposed on the upstream side of the side clutch 55. A rotation sensor 54 for detecting the rotation speed of rear wheels 17 is disposed on the output shaft EO, and determines a timing for engaging the planting clutch 51 with the controller 50 on the basis of the sum of a predetermined rotation speed and the rotation speed of the rotation sensor 54 in an interval from the disengaging of the planting clutch 51 in the first term of the turning time to the disengaging of the side clutch 55 in the last term of the turning time. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
