耕深制御装置。 The vertical swinging displacement of the rear cover 4a in the rotary tilling device 4 is transmitted to the lift arm elevation control mechanism A via the mechanical linkage mechanism B, and the swinging posture of the rear cover 4a relative to the rotary tilling device 4 is adjusted to a set range. The automatic plowing depth control device for an agricultural tractor is configured to control the lift arm 2 to raise and lower the plowing depth, and the intermediate linkage is pivotally connected to the linkage link 8 which is displaced in response to the swinging displacement of the rear cover 4a. A locking mechanism 17 is provided which operatively connects the member 9 and a linking member 10 which is operatively connected to the lift arm elevation control mechanism A, and which fixes the intermediate linking member 9 to the link 8 in a plurality of swing positions. An automatic plowing depth control device for an agricultural tractor, which is provided and configured to be able to maintain the lock mechanism 17 in an unlocked state.
