+ Really good idea to make use of the electricity in other ways than just driving. (generators, lamps, etc.) + 10 hours covers up a good day in field. - a lot of farms are away from electricity sources to charge and sometimes internet connection is non-existent. It is risky to leave a 50k machine on its own to do its job. And what to do if battery runs out on the field? - how long does it take to recharge? A lot of f…
The article says it recharges in four or five hours.
Progress yes, but at a peak of 70hp it won't be plowing much more than a hobby garden. Autonomous operation is all well and good but expect resistance. Look at how many farmers are injured by tractor equipment. They will rightly fear driverless tractors.
There's a difference between peak horsepower output and continuous horsepower output. A normal passenger car might be able to put out 300 hp, but only for a short period of time before blowing the headgasket (or destroying the drive train). Diesel engine with gobs of torque or electric is going to produce that power at a lower speed and more efficiently, so it will be able to do it longer. Being able to put out 70hp nonstop for hours on end is nothing to be ashamed of.
It seems like a farm could increase their productivity by letting these run autonomously at night and continuing to use human drivers with their old equipment during the day.

A modern engine will run at full hp for extended periods, hundreds of hours. In many ways, lower power settings at lower rpms can be harder on engines than running flat out. In a family car, the cooling system would drop the ball long before anything as substantial as a head gasket. It would overheat long before any actual damage.
Uhm.....I'm pretty sure my family has been plowing fields(and I do mean fields, not hobby gardens) with our trusty old Ursus C330[0], making a whole 30 horse power. Not sure why 70hp would be a problem. https://pl.wikipedia.org/wiki/Ursus_C-330
Yes. I've got a 28HP Kubota L-series, and have been contemplating upgrading to an M-series, but even 46 would probably set us for a good while and lots of farmers around here still find use for tractors 50+ years old that are smaller than that. Yes there are huge JDs beyond that, and the M-series tops out at 168 HP, but 70 HP still seems way beyond "hobby" level and I'm honestly and genuinely surprised to see it call…
I think it depends on the kind of crops grown. Combines, grain bins, harvesters etc are a whole diff ball game when it comes to grain or corn on 1000+ acres for commodity crop farms
This thing isn't meant to pull your 8-bottom plow attachment. It isn't the tractor a large-scale wheat or corn farmer is going to use to work the fields. Those tractors generate hundreds of horsepower and cost $250k. But there is plenty of market for a small utility tractor, and the people using those aren't all hobby farmers. You don't use your massive 500 hp John Deere 9630 to stack hay bales or cultivate your row…
Autonomy is the game changer here. For $250K you can buy 5 of these little tractors and draw 5 12ft cultivators rather than a single 60 footer. Drive one manually to mark the headland and let the other 4 fill it in.
Bingo! And no seasonal labour shortages. And you can control everything from something like. A game console.
Charging overnight + installing solar panels near the fields will solve problem. Of course it’s easier said than done, but changing processes will lead to the solution.
It would be perfect if the autonomy worked well in the dark, then it could just work at night and then charge during the day.
I’ve seen lawn mowers that do that. No solar charging, but it does cut grass in the dark. It’s actually pretty creepy to see the head light pop out from behind a corner.
Nice! Are they going to spread out into other areas? Drilling rigs? Muckers? Something to replace the Sandvik rigs and fully automate drilling and blasting would be cool. They are already partially automated (pattern, depth) but require a human to operate. I think getting humans out of mines should reduce insurance costs and health risks.

Hundreds of hours, perhaps. But not for the entire life of the engine. If a modern passenger car engine could put out 200 hp nonstop for years on end, every semi-truck manufacturer would be putting a BMW engine in it, instead of a huge cast iron Cummins. But I'm pretty sure you'd spin a bearing, or wear out the cylinder liner, or burn a valve.
