ABSTRACT:
The invention relates to a seed planter having furrow forming means in association with a pair of furrow closing wheels each of which is independently mounted relative to the suspension of the other so that each spring biased suspension arm is pivotable to enable each closing wheel to be raised, or lowered, independently of the other wheel in response to ground conditions encountered in the operation of the planter. The closing wheel mounting also includes means for adjustment of each wheel whereby the angle of attack of each wheel may be varied and importantly enable adjustment of the wheel spacing so that the distance between the wheels can be adjusted and enabling the wheels to be set to run straight with the direction of travel of the planter and at any desired seed planting depth.
