ABSTRACT:
Self aligning sled apparatus for spraying herbicide to the ground surface of the top of the crop row and under the low growing foliage of row crops. Alignment of the plurality of shield sled apparatus is accomplished by the trunks of the crop plants guiding the shield sleds spaning the furrow between rows. Each of the plurality of shield sleds is attached by parallel linkages to a horizontal tool bar secured to the self-propelled sprayer or tractor. The connecting parallel linkages allow each sled to move vertically, horizontally, and rotationally as needed independent of the tractor and of the other shield sleds. As the apparatus moves forward, shields affixed to the shield sleds engage the low crop foliage and lift it upwards in order that spraying mechanism near the rear of each shield sled may apply herbicide to the ground and weeds under the crop foliage. At opposite sides of the plurality of shield sleds are provided a modified shield sled with one or more spring tensioned pivotable arms engaging adjacent plant rows in order to urge more complete engagement and raising of the leaves of the plants on the affected sides of each row.
