"Downtime — the thing that actually costs a farmer money during planting or harvest — shrinks dramatically when you don’t need a factory technician with a laptop to diagnose a fuel delivery problem."

Tractors aren't cars. It isn't merely inconvenient if they are unavailable at crucial times, so ease of repair is critical. Farmers have always done as much of their own maintenance as possible. John Deere has spent a lot of time taking away the reliability and ease of repair that farmers need in order to give them "advanced" features they don't need.
Farmers who want advanced capabilities might now look to build them on top of no-tech tractors with open-source solutions rather than trusting John Deere again. That way, if the "would be nice" tech has problems they can rip it off and get the harvest in without it.

Well, sure. Maintenance is an off-season job. Its that or sit on the couch watching TV, so you may as well be in the shop getting equipment ready. Even if it takes you longer than an experienced tech, does it really matter? Not really. The winters are long.
Repairs are a different story. When things break, you need it fixed now. Wasting a day trying to figure out how to separate complex, seized parts from each other isn't time you have. You're going to be hiring a mechanic who has done it a million times before.
Of course, more important than who does the work is part availability. Having the human capacity to get something fixed means nothing if you cannot also get the parts you need. I've certainly been caught more than once needing to wait a week on a part, which is not a fun place to be. And this is where John Deere has focused their business: Doing more to keep parts available near to where the farmers are, so that you can get parts exactly when you need them. This is, above all else, why John Deere is the market leader.

I have been going down this road and am starting to regret it a bit. The saving grace is that I have found enjoyment in building a system of my own. But if I found it to be a chore, at this point I'd have deep remorse that I didn't just pay someone like John Deere for a fully delivered, highly polished solution. I know the HN crowd tends towards the DIY, but, having actual experience here, I don't see this happening outside of the small subset of farmers who find fun in it. It is a decent hobby for those so inclined, but from a purely commercial perspective the time and effort can be better put to use elsewhere.
If you maintain your stuff you know enough to fix some things and you know when you can't and need to call a mechanic (or a friend who knows more and can do it).
You can fix things, but can you really justify the time to do when you need an operational machine?
1. No matter how great of a shade tree mechanic you are, you will never be able to fix it faster than someone who does it every day. They have found all the little tricks and quirks about your machine that your casual maintenance will never uncover.
2. While large farms with full-time mechanics on staff have been known to make deals to warehouse parts in their own shop on consignment, much more realistically for any kind of normal farm you are going to have to drive to the dealership to get the parts you need. Whereas the dealership tech can bring the parts to you. Meaning that you have to travel twice as far, taking twice as long, to get the parts back to your equipment than if you call a mechanic.
The things that are likely to fail under use where there has been proper maintenance tend to be the things that are unpredictable and catastrophic, at very least requiring parts, and most likely requiring advanced knowhow. And at that point, the dealership tech is going to be faster at getting you back up and running, even if you could theoretically pull it off yourself. So, realistically, there isn't much of a compelling case for doing your own repairs when time is of the essence.
Farmers are often willing to accept more downtime to do it themselves out of pride, though. I admittedly often fall victim to that myself, so I get it. But it’s clear that the farmers who are serious about farming as a business aren’t dinking around trying to fix things themselves. It is not economically prudent to do so. Granted, not all farmers farm for business sake. For many it’s more of a hobby or lifestyle and wanting to be a part-time mechanic can play into that.
