Abstract: A twin row seedling planter is provided with a new mechanical system for ejecting seedlings into a cut in the ground made by a dibble after the dibble has cut to a selected depth. The planter also features an improved modular lay-out of planting beams, packing beams and wheel support beams. The operators' station is located for ease of access to the planting dibbles. A simple and efficient system is used to raise and lower the packing beams and the planter frame in sequence.

Abstract: The present invention provides a planting apparatus including a mobile frame suitable for forward travel over the ground. A planting arm is movably mounted to the frame and extends from a mounting location. The planting arm includes a dibble remote from the mounting location and adapted to cut into the ground when the dibble moves toward it during forward travel of the frame. A planter means is carried by the planting arm and is adapted to support a seedling for planting in the cut made by the dibble. The planter means includes upright spaced apart side walls at the rear of the dibble and a bottom ledge which together form a pair of side walls and the bottom respectively of a pocket for receiving and containing a seedling. The apparatus includes an elongated ejector tongue extending downwardly into said pocket to a point adjacent the bottom ledge and which forms a frontal wall for the pocket.

Abstract: A plow apparatus for laying cable, pipe, tile and the like underground having a blade with an upwardly extending shank portion for support. A blade holder connects the shank to a plow-pulling crawler tractor and the holder has an opening therein to receive the shank. An arm is pivotally mounted on the blade holder on one end of the arm to press the shank against an interior surface of the holder in the opening. A blade dog pivotally mounted on the holder is also provided to lock the shank in the holder at a selected height by means of recesses formed on the rear surface of the shank at various heights. One of the recesses is engaged by the blade dog in the locked position. The invention permits one machine operator to quickly and easily adjust the cutting depth of the blade without the use of tools.
