10•Energy - Machinery - Regrarians Novel Machinery Development #19
~ 2026 - Regrarians Ripper Zappa MK1 ('RRR')
Thanks to Bob Barton (Landscape Architect and Director of MALA), Regrarians’ Darren J Doherty was introduced to Covalent Land Australia Managing Director Justin Glass. Our first conversation went directly to making agroforestry soil preparation less invasive, less herbicide dependent and lower in cost.
On the back of the developments with Earthbanc & Earthtree India in 2024, and building on the 2022 concept sketch, Darren designed (using QCAD) and fabricated (laser cutting by Online Laser & welding by Paul O’Keeffe of ‘Amped Up Welding) an entirely new prototype—mounting the power harrow chassis directly onto a Tilco Hydramax ripper, so that in the event of hitting a rock, the Hydramax and the power harrow would be lifted out of harm’s way and then be re-inserted without stopping the tractor.
Justin introduced us to award-winning builder David Martin (The Sociable Weaver) and Regrarians Georgi Pavlov and Darren J Doherty completed the farm plan of his 610ha Omeo farm, including its 400ha+ carbon agroforestry project that Covalent were managing.
We have been using this site as a test-bed for the use of the ‘RRR’ and it has worked really well except for a breakage of the driveshaft of the Orizzonti Srl Macchine Agricole power harrow assembly we brought from Italy. It served as a lesson to bulk up the shaft diameter and housing etc. for the commercialised model that is coming next year thanks to a well-known Australian agricultural machinery manufacturer.
