Best known for its beet cleaner-loaders, Norfolk firm CTM Harpley Engineering has developed a range of potato bed destoners/clod separators.
Long and short wheelbase versions are available with a choice of up to five webs or a combination of stars and webs. The company claims faster forward speeds are possible thanks to independent wheel levelling and a square-profile roller running behind the lifting shares which, as well as propelling material up onto the first web or star-roller, has a certain clod-shattering effect.
A hydraulically-driven scrubber-web above the main separation area can be run in reverse to increase the amount of time soil is kept on the webs and stars. Prices start from £43,000.
