Taking 200 + acres out of HLS grass and was planning on dipping the toe into DD, sprayed off today with Glyphosate as the grass ( according to the chap with the drill ...... JD 750a .....) is to long to drill ( its his first year with it ) my main concern is its really hard on top, was a job to push a stake into it today for marking out, and it was steel with a point on it. Will this drill or have I got to find a plough ?
