Plenty of options for putting auto steer on a dumb tractor already exist.
But there's more to agtech than driving a tractor around, a lot of what these big integrated systems do (at the high end) is very data driven -- determining where and how to plant, irrigate, fertilize, etc. There's a lot of integration work beyond just making the tractor drive.
I just don't think you're going to effectively compete with big agtech by putting a bunch of parts in a box, shaking it, and hoping you end up with a beautifully integrated solution. Integration hell is the reason big commercial firms dominate when it comes to large integrated systems.
If you want to see a couple of guys learning how to farm from scratch, visit https://www.youtube.com/@spencerhilbert. Spencer and his brother made a bit of money off games and Youtube and have been starting out on corn, hay, as well as raising beef. It gives a pretty good insight into how pervasive tech is in farming, and how despite that, how much of farming still relies on hard, physical work.
However, I'm not as interested in being a farmer at that level. I'm much more interested in the homesteading aspect of farming. I'm not trying to feed the world as much as me and mine and maybe some extra. So not just farming, but also some ranching with sheep/goats/chickens/pigs. I have friends doing this that I'm keeping an eye on. They had a head start as their kids grew up in FFA and are already familiar with raising live stock, and then having them processed to make that part much less daunting.
> raising beef
Is that cows? English isn't my first language, so I thought beef was the word just for the meat, with all Normans eating while Saxons raising thing.
So a DIY solution is aiming for somewhere in the center of the market -- enough scale that it makes sense to bother, but not enough enough money to avoid the headache of DIY. It might make sense for some mid-sized farms in developing economies, but it seems to be a narrow window to me.
How difficult is this to implement outside of big ag-tech? I feel that a community of experienced farmers and programmers (or programmer-farmers) could tackle this.
The bigger agcorps have tones of integration.
The machine, from tractor to combine and everything in between often feeds data together to produce a holistic understanding.
Things like - How much fuel was used - Where your tractors and sprayers drove - Soil samples and content - How and where every bit of chemical and fertilizer was applied - What weather hit your field - How much and and the moisture content of every bit of the field you harvested
It goes on an on.
Yes, but how useful is the integration?
The sprayers/spreaders can be connected cheap computer to achieve most of what you describe.
I used to do literally that but in aircraft. Must be easier and cheaper in tractors
But if you're observing a fleet of 100+ machines you kinda need some integration and a central location. Which in turn connects to multiple other services like weather, crop markets, fuel prices etc.
A tractor is a big thing to have rolling around unsupervised. I would want a lot of safeguards. Blindly going from one GPS point to another sounds like a nightmare.
Incumbents thrive on the myths about what they do being hard and impossible to replicate.
Yes, it is a lot of work to replace what you can get off the shelf today. But it isn't like the basic tech itself is all that hard to replicate step by step if you accept that it takes time and the first N development stages will give you something that isn't as feature rich and polished. And if one makes it open source, interoperability will be easier to do something about.
Perhaps some of the analysis tools/services you can buy today will be hard to replicate, but I doubt they are that hard to replicate. And it is worth having slightly suboptimal results for a couple of seasons than being on the receiving end of a hostage-situation.
But yes, it is certainly a huge effort to get what you actually need.
For farming, it’s even more tough because the market has a really uneven distribution. Usually the best place to tackle huge incumbents is in the midmarket. They’re big enough to need your automation, but they’re small enough to take a risk to save some money, and the features you haven’t built yet aren’t blockers for them.
But there’s basically no midmarket farming, all farms are pretty much either really big or really small.
