LIFT CONTROLLER FOR WORKING MACHINE OF AGRICULTURAL MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a rice transplanter capable of lifting a seedling-planting device without deteriorating the stability of a travel frame, when the travel frame climbs a ridge at the exit of a paddy field, simultaneously planting seedlings at the corner of the paddy field with the seedling-planting device used as a work device in the final stage of the planting work in a butt and subsequently lifting the seedling-planting device with respect to the travel frame. ;SOLUTION: This lifting control device for the work device of an agricultural work machine has a longitudinal frame inclination detection sensor 22 for detecting the longitudinal inclination of a travel frame, and a control means 32 for lowering a velocity V for lifting a seedling-planting device and switching the velocity V into a slow forcible lifting speed V', when the longitudinal frame inclination detection sensor 22 detects the front-lifted inclination of the travel frame and when an operation for lifting a seeding-planting device is commanded.;COPYRIGHT: (C)1999,JPO
