    摘要： A reversible plough has a headstock formed from upper and lower parts hingedly connected about a transverse axis, the reversing spindle being mounted in the lower headstock part and carrying a crank arm connected by a link to the upper headstock part. As the reversing spindle is rotated, relative hinging movement between the two headstock parts causes the reversing spindle to tilt in a vertical plane, the load in said link counterbalancing to a degree the offset center of gravity of the plough frame and reducing the torque required to reverse the plough frame. The plough frame carries left handed and right handed plough bodies and the center of gravity of the plow frame is laterally offset from the longitudinal axis of the reversing spindle. The reversing spindle is adapted to be tilted in a vertical plane simultaneously with the reversing spindle being rotated so that the center of gravity of the plough frame can be maintained substantially in a horizontal plane as the plough bodies are being moved to and from their right and left handed plowing positions. The mechanism for rotating the spindle about its longitudinal axis includes a pinion on the reversing spindle and a moveable rack cooperable with the pinion, with the rack being connected between opposed hydraulic pistons.

    摘要： An agricultural machine including a fixed mast secured to a frame body so as to be projected from a front end portion of the frame body, a movable mast which is pivotably mounted to the fixed mast so as to be arcuately movable in an agricultural working direction relatively to the fixed mast and has a mount portion to which a top link of a tractor is mounted, and a mode selecting mechanism provided between the movable mast and the fixed mast for changing and fixing a positional relationship between the movable mast and the fixed mast interlockingly with a lifting operation of the agricultural machine to thereby freely change a penetrating angle of the agricultural machine into the soil.

    摘要： THIS CONTROL DEVICE, FOR THE DELAY-ACTION ENERGIZATION OF AN ELECTRIC MOTOR OF THE TYPE ADAPTED TO BE BRAKED BY SHORT-CIRCUITING THE ARMATURE DRIVING A MECHANISM HAVING A PREDETERMINED FIXED-STOP POSITION, COMPRISES A FIXED-STOP DEVICE FOR SHORT-CIRCUITING SAID ARMATURE AND A THERMAL DELAY-ACTION DEVICE ASSOCIATED WITH SAID FIXED-STOP DEVICE FOR RESTARTING THE MOTOR AFTER A PREDETERMINED TIME PERIOD. IT UTILIZES A HEATING-WIRE THERMAL DELAY-ACTION DEVICE WHEREIN THE HEATING WIRE PROPER IS OPERATIVELY CONNECTED TO A CONTACT ARM MOVABLE BETWEEN A MOTOR ENERGIZING CONTACT AND AN ARMATURE SHORT-CIRCUITING CONTACT AGAINST WHICH SAID WIRE IS NORMALLY URGED IN ITS COLD CONDITION.
