I wonder how sustainable the business model is. Eventually, you saturate the market with your tractors, and if they work as advertised, they are owned and maintained for decades. A lot of people are out there farming with 60-80 year old tractors. I would suspect most of the OEM parts that need replacing are where most wear and tear is happening (the engine). Those parts come from Cummins, not this startup.
In the meantime, they have to maintain a very high fixed cost base in their factory, distribution network, and skilled unionized workforce. I'm really not even asking about how will they maximize shareholder dividends, I just mean how do you not go bankrupt after you sell your first 10,000 tractors.
