Electric Combine Closer To Reality

Electric Combine Closer To Reality COMBINES Miscellaneous Terry Krieg and Malcolm Lucas of Kangaroo Flat Australia combined their skills and expertise to build the world’s first electric combine Krieg with a power industry background and Lucas an innovative farmer-inventor created and tested their prototype Linttas Electric Harvester over nine years Surprisingly this working original was stolen from the farm in broad daylight Fortunately the pair were already developing a new and upgraded design based on their learned experience and observations “An electric combine is well overdue in the history of agricultural machines ” Krieg says “Especially as it’s arguably the most complex machine on the farm ” Since the earliest typical harvesters Krieg says there’s been little or no concern for energy conservation or lowering the carbon footprint “We’ve just made things bigger adding more horses or mules then larger engines now over 1 000 hp in some models ” He explains that electricity saves energy and optimizes performance Wasted energy consumption including hydraulic pumps belts pulleys chains and transport sections is eliminated in the Linttas threshing process “Electric drives on each shaft each with variable speed drives help tune the threshing and grain separation process for optimal energy use and the highest performance ” Krieg says “We achieve the tuning using sensors and machine learning algorithms ” Grain separation can be precisely adjusted on the fly “Another big reason for electric is machine simplification and ease of repair ” he says “From the outset we considered the ‘right to repair ’ Because we only use off-the-shelf components and add self-diagnostics plugs and sockets the operator can diagnose and repair problems guided by the software diagnostics An electric harvester is cheaper to purchase repair and easier to update when new technology comes along ” Battery solutions are generally considered feasible for smaller agricultural machines up to 100 hp but not for equipment as large as a combine on broad-acre farms The Linttas Electric Harvester is hybrid-electric using a single diesel engine running at optimal speed to drive an onboard generator and supply electrical energy “Since it’s always performing at optimal levels due to the machine learning artificial intelligence and an infinitely adjustable grain separation process the engine is expected to last longer and use up to 30 percent less fuel than a traditional combine ” Krieg says Eventually the pair hopes to upgrade the diesel engine replacing it with a hydrogen-powered alternative when such engines and fuel distribution systems become readily available “Right now we’re aiming at a lower carbon footprint for the life of our units Our diesel-electric solution saves energy and is simple to operate and repair ” Krieg and Lucas have patented the electric machine but have yet to start manufacturing it They’re open to producing the combine with an industrial partner who supports their design concepts and aspirations The commercial production timeline depends on investment and collaboration The pair are poised to enter an agreement with a research partner for the final concept simulation and modeling which they estimate will take 12 months They hope to use that modeling to optimize their design and develop the control algorithms before entering into a manufacturing agreement in 2026 “We know what we’re developing will forever change how machinery is designed ” Krieg says “We recognize the industry may see this technology as a threat to their business models so we’re thrilled to get this to market but not by rushing headlong We won’t partner with anyone who doesn’t share our ideals regarding sustainability and the ‘right to repair ’ This technology isn’t pie in the sky We know it works based on nine years of real-world experience ” Contact: FARM SHOW Followup Linttas Electric Company ph +61 0 437 506 482; terry krieg@linttas com; www linttas com
