Jim George has come up with an undeveloped product on every farm in the country: a way to harvest biomass from hedgerows.
His Hej Harvester concept provides farmers with the prospect of recovering the large costs associated with hedge trimming by collecting wood-based materials that are usually left to rot on the ground.
The system features a wide cutting head designed to chop the top 0.6m of growth into uniform pieces in a single pass.

To achieve this, he designed a rotary cutter that carries special teeth that can be moved to vary the length of the chop. This means that the material can be sliced into relatively short lengths if it is supplied to a household biomass boiler or if it is left slightly longer for use in an industrial scale facility.
Using teeth instead of traditional flails also means that hedges can move up to 50% faster. This is an attractive outlook for contractors who handle hundreds of miles of hedges annually.
The cuttings are thrown behind the chamber, where they are sucked into a large hopper attached to the tractor by a pto-driven vacuum.
Tentatively, the design features a duct with a different length than the telescopic hedge cutter arm, but George also sketched a plan to combine the two. This means using tubular steel for the arm, which allows it to also function as a vacuum pipe and therefore provides a little more protection from damage caused by stray branches.
Luggage ejection includes backing up to a trailer and raising the mast hopper powered by a hydraulic ram. He hasn’t determined the exact hopper capacity yet, but will try to make it as large as possible to minimize the number of offloads.
The biomass can then be burned in a farm boiler or stored and sold to commercial energy producers. The market is currently ordering prices from £ 150 to £ 180 / ton.
George, who has been involved in the project for several years, is from Malvern, Worcestershire and is currently looking for a manufacturing partner to complete a patented design and start production.
