About Arm Eggiwil AG
Arm Eggiwil AG is a family business from Eggiwil in the Emmental, now run in its second generation by Lukas Arm (graduated engineer in mechanical engineering, FH). The company combines three business areas: repair, service and maintenance of agricultural machinery (tractors, mowers, harvesting machines), the sale of agricultural machinery, used machines as well as small and garden equipment from well-known brands, and its own metalworking shop for the design, manufacture and installation of custom metal products such as garden gates, fences, stairs and metal constructions. A special feature is the traditionally developed own-brand products for agricultural engineering, including spiked wheels for motor mowers and axle mowers, the Vielfrassbalken multi-purpose mower bar, hose reels H500/H1000, the trailing hose distributor and the slurry distributor V70. The company also includes the site company Jost Landtechnik AG in Langnau. Customers are farmers and agricultural businesses in the region.
