<p><P>PROBLEM TO BE SOLVED: To prevent the slippage of a front wheel when going over a ridge, and to enable secure going-over of the ridge. <P>SOLUTION: The riding-type rice transplanter 1 equipped with a vehicle-outside operation tool 12 for carrying out the traveling operation from the outside of the vehicle when going over the ridge, is equipped with a differential locking mechanism 29 for selectively locking the differential motion of the right and left front wheels 10, a clutch pedal-operation system for operating a clutch mechanism 13 and a braking mechanism 30 according to the operation of a clutch pedal 35, a synchronizing operation tool 52 operable to a synchronizing position or a synchronization-releasing position, a vehicle-outside operation tool-synchronizing mechanism 63 synchronizing the vehicle-outside operation tool 12 with the clutch pedal-operation system according to the synchronizing operation of the synchronizing operation tool 52, and enabling the operation of the clutch mechanism 13 and the braking mechanism 30 by the outside operation tool 12, and a differential locking-synchronizing mechanism 74 for automatically forming the differential locking mechanism 29 into a differential locking state according to the synchronizing operation of the synchronizing operation tool 52. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
