Seeding tool

A seeding tool for attachment to a vehicle to be drawn through a soil bed in a forward direction for planting seeds in the soil bed at a desired depth, the seeding tool including:

• a frame supported by a frame wheel so that the frame is pivotable about a wheel axis;
• a plough assembly attached to a rear portion of the frame, the plough assembly including a seed boot for planting seeds in the soil bed at the desired depth;
• a fixed drawbar hingedly attached to a front portion of the frame so that the drawbar is pivotable about a drawbar axis that is parallel to the wheel axis;
• a front height sensor attached to the front portion of the frame to provide a front height signal;
• a rear height sensor attached to the rear portion of the frame to provide a rear height signal;
• and
• an actuator located between the fixed drawbar and the frame operable to adjust an angle between the fixed drawbar and the frame to level the frame relative to the soil bed based on the front and rear height signals;
• wherein the plough assembly further includes:
• a digging shank to extend downwardly into the soil bed, wherein the seed boot is pivotally attached to the digging shank, such that the seed boot is vertically movable relative to the digging shank by an adjustment distance;
• and
• a press wheel attached to the seed boot, to press on the soil bed and support the seed boot at the desired depth below the soil bed;
• wherein the actuator is operable to adjust a position of the plough assembly to maintain the seed boot at the desired depth by leveling the frame relative to the soil bed if a difference between the front and rear height signals exceeds the adjustment distance.
