34の係止部34aが係入する凹部Tを、前記揺動アー
ム30が設定適正範囲以上上昇操作側に揺動するに伴っ
て係入する位置に位置させる状態で前記揺動アーム30
に形成しであるトラクタの耕深制御装置。The operating rotary shaft 8 for the control valve 7 of the hydraulic cylinder 3 for raising and lowering the tiller is connected to the control valve 7 via a feedback link mechanism in order to automatically raise and lower the tiller B to a height set at its rotational position. A lifting control swinging arm 30 connected to the rotating shaft 78 is biased toward the descending side, and the swinging arm 30 is pressed and swinging toward the rising side in order to maintain the set plowing depth. Locking operation arm 3
4 is a tractor plowing depth control device which is interlocked and connected via a mechanical linkage mechanism to a ground sensor 37 for detecting plowing depth, which is attached to the tillage device B so as to be movable up and down, the locking portion of the locking operation arm 34; The swinging arm 30 is placed in a state in which the recess T into which the swinging arm 34a engages is located at a position where the swinging arm 30 engages as the swinging arm 30 swings toward the upward operation side beyond the set proper range.
A tractor's tillage depth control device.
