Horse drawn finger weeding from Pioneer 

This is a new steerable toolbar from Pioneer with finger weeders designed for horse-drawn weeding. We got to see this in action in transplanted cauliflower in 'thumb' of Michigan a couple of weeks ago. Fingers are attached to short spring-loaded arm on end of parallel linkage which also has side-knives and sweeps. A different set of fingers can be attached in vertical orientation to get edge of plastic.
