Three tons of feed a year used to move through this farm one 50-pound bag at a time.

Store shelf, cart, truck bed, garage, garbage can, 5-gallon bucket, trough. Every bag touched about four times. Call it 12 tons of lifting a year to feed three tons of grain.
This month we replaced the whole thing with a used 6-ton bin and auger — $3,100 delivered and installed, against $4,800 for a new one that held half as much. That's $1,700 banked on day one, for twice the steel.
Here's the honest part most farm posts skip: the feed savings alone don't justify it. Bulk runs about 24% cheaper than bags — $285 a year savings. On feed dollars only, a $3,100 bin takes about 11 years to pay for itself. If cheaper feed were the whole story, I'd have kept my $3,100.
It was never the whole story.
The feed store is a 27.4-mile round trip, twelve times a year — 329 miles that existed for no reason except that feed came in bags. That's 21.9 gallons of diesel through the F-250, about $104 at Tennessee prices, and $230 a year at what a truck really costs per mile. Plus an hour per trip — 40 minutes driving, 20 loading and offloading. Twelve hours of Saturdays, annually. Count all of it and payback lands around 4.5 years, not 11. Same steel. Different question.
And then there's the reason that doesn't have a payback period at all.
I had back surgery spring 2025. Lower back. Then I went right back to moving three tons a year across the repaired part, fifty pounds at a time, because that's what the chore required and the chore doesn't negotiate.
The crew here is me, my wife when she can be, and kids with considerably more enthusiasm than payload. The 50-pound bags were never a team sport. A bad back on a place like this isn't an expense — it's the end of the operation. The cows don't care whose back went; they still eat at six. (not their main meal but different topic for a different day. Shameless Plug for DisneyFarm.com)
The lifting stopped the day the bin went up. Not gradually. Not at year 4.5. Day one, before it saved a nickel. (Well Third day, had to order a truck delivery for $945 for 3 Ton)
I spend my working life optimizing systems where the worst outcome is downtime. This was a system whose single point of failure was a 44-year-old lumbar spine that had already been opened up once — and I'd been loading it with twelve tons a year (a bag and a bucket at a time).
But the part that gets me excited is what a bin makes POSSIBLE.
A bag system cannot be automated. There is no API for a man carrying a bucket. The moment feed lives in a bin with an auger under it, "feed the cows" stops being a chore and becomes a function call — and everything I've spent years learning in a homelab suddenly applies to livestock.
The build, in order:
• A dedicated electric line to a switched circuit — because the first rule of automating a physical thing is that the physical thing gets its own breaker.
• A Wi-Fi timer on the auger. Not an industrial controller. The same $30 timer people put on a hot tub. It's already Alexa-native, so the farm's existing voice layer inherits it for free.
• A hardware timer relay in line with it. This is the part I want to be loud about: software is not allowed to be the only thing standing between a full bin and a buried trough. If the switch sticks on, if my code throws at 2 a.m., if the network drops mid-command — the auger still physically cannot run more than a few seconds. Automate the convenience. Hard-wire the limit.
In a homelab, a bug restarts a container. On a farm, a bug hurts an animal or tears apart a $3,100 asset. Same code, different blast radius. The failure mode is what changes, so the failure mode is what you engineer against.
And the kicker: the bin didn't touch the worst chore — the daily 5-gallon bucket to the trough, 365 times a year, about 61 hours. That's what this weekend's ~$100 of parts eliminates. A hundred dollars of automation returns more hours than $3,100 of steel returns dollars. But it could not exist without the steel underneath it.
That's the lesson I keep relearning: the automation isn't the project. The project is getting the physical world into a state where automation is even possible.
The bin wasn't a feed decision. It was a back decision, a logistics decision, and — the one I didn't see coming — an API decision that happened to be made of steel.
The spreadsheet only ever knew about one of those.
