ABSTRACT:
The present invention is a mounting device for individually mounting rotary hoes on the shanks of row crop cultivators. The tractor pulls shanks through the fields to cultivate the soil with rotary hoes connected to the shanks by a mounting device. The mounting device includes a portion which clamps to the shanks and a portion which is pivotally connected to the clamping portion and extends to a rotatably mounted rotary hoe. The hoe may float over irregular surfaces of the ground to penetrate and dig up the soil. The rotary hoes may be biased by a spring to maintain a relatively constant ground depth, and they may include stops to limit their forward movement, backward movement, or both.
