When you are a farmer/rancher you work when you need to work. Sometimes its 20 hour days. Sometimes its 1 hour days. Planting seasons can really fuck you if you miss 3-4 days and your crops will suffer. It really depends. It is far more complicated (and sometimes more simple) than one would think. However, there are also open source projects to build stuff like these "GPS" farm tools that are trying to make them more robust and.. well. Free(ish) as long as you are not a moron and willing to do the work. Despite what many people think, farmers and ranchers are far more intelligent than you would expect and a project like this would just be another tool in the belt. There is something about self-reliance that seems to tend toward ingenuity and intelligence. Who would have thought that everything giving you everything without effort could possibly make your... Less capable? To add a bit more to this. If you are not a "industrial farmer" and running your own land. You have to handle all of the business side of things too. Accounting, hiring/firing, planting schedules or breeding schedules, soil samples and amending the soil. Ordering for seeds/fertilizer. Despite what many people think. Farming/ranching is not as easy as you think. It takes long hours, hard work and small profit margins. All with little time off if ever if you cant get family or your neighbors to help you out. One bad season can also wipe out all of your profit and if you don't have savings you will lose your land since you often have to borrow against your future crop/heard.
