Title:
CONTROLLING APPARATUS FOR TILLER
Document Type and Number:
Japanese Patent JP3073901
Kind Code:
B2
Abstract:
PURPOSE: To provide a controlling apparatus for a tiller capable of achieving excellent tillage while the tiller enables a quick lifting of a rotary tillage apparatus by a controlled operation with a forced lift-controlling means.
CONSTITUTION: This controlling apparatus is composed of an automatic tilling depth-controlling means 18B, a forced lift-controlling means 18D and a lifting speed-controlling means 18E. A ground height-detecting means S3 detects the ground height of a rotary tillage apparatus linked to a mobile machine body freely driven in a vertical direction. The controlling means 18B controls a vertical motion of the tillage apparatus so that the ground height of the rotary tiller, determined by the detecting means S3, agree with the target ground height predetermined by a tillage depth-setting means 21. The controlling means 18D forcedly lifts the tillage apparatus until the specified lifting limit based on a lifting directive from a lift-directing switch 24 having priority to the forced actuation by the controlling means 18B. The controlling means 18E controls the lifting speed of the tillage apparatus in such a manner that it is lower in the first half and higher in the second half in the moving range during the forced lifting of the tillage apparatus under the controlled operation with the controlling means 18D.
