摘要： Cultivating tines, each having opposite cutting edges, are pivotably supported by tine mount members on a tine shaft reversibly rotatable about a horizontal lateral axis. One of the cutting edges of the tine is retainable in a position rearward with respect to the direction of forward rotation, while the other cutting edge is retainable in a position rearward with respect to the direction of reverse rotation. When held in each of these positions, the tine is restrained by resistant force imparting means from being pivotally moved by a centrifugal force. The resistant force to be imparted by this means is smaller than the reaction to be produced when the tine is driven into the soil.

摘要： PURPOSE:To prevent the floating and toppling of a rotary, by using a hydraulic actuator to adjust the distance of a front gauge and the ground and controlling the actuator by a detection signal transmitted from a plowed depth detector or a level detector. CONSTITUTION:A rotary apparatus 5 furnished with a plowing part 6, a covering apparatus 7 and a pair of right and left front gauges 8, 9 is attached to a tractor 1 through a three-point link mechanism 10. The front gauges 8, 9 are supported at a rotary machine frame side with hydraulic actuators 11, 12 and the distance between a pair of right and left gauge wheels and the ground is controlled with a controlling means through a detection signal transmitted from a plowed depth detector 16 or a level detector 17.

摘要： PURPOSE:To eliminate extremely forward slant placement of a working machine on the ground in connecting a tractor to the working machine, by setting specific oscillating members in a specific state and laying a means to releasably lock the oscillating members in the maximum oscillation position at the opposite side of the tractor. CONSTITUTION:A left and right pair of oscillating members 40 are supported by a shaft 41 on front part of a left and right pair of attaching plates 17 of a coupling member 14 connect side end part of a working machine of a top link 10 and both low links. The oscillating members 40 are releasably locked in locking members 55 at the maximum oscillation position at the opposite side of a tractor wherein an engaging shaft 42 inserted into the oscillating members 40 is engaged with cut dents 43 of the attaching plates 17. The maximum oscillation position of the oscillating members at the tractor side is a position wherein the base part of the oscillating members is brought into contact with a main body 15.
