As a farmer I am interested buying one, especially as I am using tractors for light work: spraying, towing and light field work. There are few hacked tractors already available, but it will take some time before supply chain mature enough.
I am pessimistic about having heavy duty industrial scale tractors with current battery technology. Those machines are monsters and when you interpolate consumption from light workloads to those monsters it just doesn't compute. Another angle in economics is that those machines have to work for many hours a day (combines in heavy seasons run for 12+, 7 days a week) which is also hard with current batteries.
- JamisonM 6y agoI believe that this is the area where hydrogen technology is supposed to step in. I am sceptical of that as well though. As you note the light loads will do well with electric systems, there is a lot of low hanging fruit to take care of on every farm before the big horsepower will get tackled.. and maybe autonomous tech will get good enough that the answer will instead be replacing a lot of the high-HP jobs with more lower HP jobs instead?
- jelliclesfarm 6y agoDepends on the what’s being grown. Sometimes you need monster HP. Even with light work, electrical systems add to the weight leading to built in inefficiencies. I don’t know if we can move away from diesel at this point.
- JamisonM 6y agoYou need monster HP when you are trying to do a lot in a single pass, when I talk about the idea of autonomous+electric I am envisioning trading less work per pass for less HP and trading that off for more units and less labour. Back in the bad old days you'd work 6 inches deep with a single-bottom plow behind a single draft horse! You can always break it up enough to get the HP down! ;)
- jelliclesfarm 6y agoIt’s suitable for vegetable and small acreage farms. That’s the farm automation platform I am working on...we can swarm small Ag bots over connected small acreages. It’s the best use of robotics and automation tech in the field because every market farm or small acreage farm flips beds 2-3 times/year and have crops that have continuous multiple harvest windows.
- vvanders 6y agoIf you're doing ground work with a tractor then weight is actually a good thing. The way it was always explained to me is weight determines what the tractor is capable of, horsepower is how quickly you could do it.
- dejv 6y agoWell, the time window in which you should do certain farming operation without product degradation is often quite short and having smaller tractor doing it autonomously might not cut it. Once you need to buy few of those to replace one you are buying into bigger chance to failure, more maintenance duties etc and it might result in higher cost per unit.
- Ekaros 6y agoI think biogas might be winner for farms. If reliable and cheap production and liquefaction could be done. LNG seems perfectly reasonable self-supplied source for farms. There is likely enough waste material around for power needs of farming equipment. And source is local.
- afandian 6y agoThis is an insane idea. But. Given that unlike cars, tractors work in a bounded area, could some kind of permanent power cord work? Given that irrigation water can get to all those crops, can't a power cable?
- Loughla 6y agoI think the difference is that water lines for irrigation are mostly aerial except for the one spot where they enter the ground water source. Further, the lines themselves don't move, the machine holding the lines moves. Finally, there is a substantial difference in 'I have a small water leak' and 'I have a small power leak'. Maybe I'm being too closed minded, but I can't see that working long term. The stresses of being dragged around the field, or the infrastructure required to hang the power cord overhead would just be outlandish. For some reason, I can't get the picture of a powered grid of wire mesh over a field like giant bumper cars.
- Tossrock 6y agoSeries of heavy-payload drones to keep the cable aloft. The drones can draw power from it to power themselves indefinitely. And of course you'd need a massive slip ring at the tractor.
- jelliclesfarm 6y agoDo you mean like a center pivot? Actually that’s not a bad idea. In theory.
- eecc 6y agoI was about to post the same. After all, if I can mow my lawn with an electric mower without electrocuting myself with just a little bit of route planning, can't farmers do just the same?
- trhway 6y agofor farm situation i think battery swaps would work much better. Also giving that the farmers can also have wind/solar installs those extra batteries can be used as grid storage the rest of the time.
