I'm not sure where you are in the world but in my country we absolutely do spend the vast majority of profit from harvest or the sale of stock reinvesting in farm infrastructure because when you do that it's a tax deduction if we didn't 30 % of your profit would go in tax. small farms may not buy large items but everyone that runs a farm does something similar in my country. I don't know how much these guys intend to charge a month but I know that the smart tag people for cattle want $5 a month a head for what is good data but the price makes it completely non viable.
