Ursa Ag, a Canadian startup, is manufacturing tractors with remanufactured 1990s diesel engines and no electronics, selling them for roughly half the price of comparable machines from established brands. The company's tractors use mechanical fuel injection and have no proprietary software, making them easier to repair. This approach is seen as a response to the trend of large manufacturers like John Deere producing complex and expensive equipment that can only be repaired by authorized technicians. Ursa Ag's tractors have generated interest from farmers who prefer simpler, more repairable machines.
