I think another challenge for farming equipment would also be the uneven terrain, risk of things coming up and piercing or shorting the battery, and also overheating. The first one can be fixed by installing a metal plate like Tesla did after cars kept blowing up. The overheating part might be a bit more tricky. I suppose an air conditioner dedicated to the battery would work alright.

The other thing is, using it day in and day out, from sunrise til sunset or even later, will probably wreak havoc on the battery health. I know EVs in general suffer from this, too, but I feel like it’s even worse for farming equipment, because you know they’ll get a let of extreme use, whereas a lot of people with EVs might only use it for a commute into the city, or a trip to the shops

One final thing, just based off the farmers I know (used to live in the country), a lot of them, maybe even the vast majority, have no interest in upgrading until they have to. If it works, it works. Anything new might not work as well, and require precious time to learn how to use well or properly. They tend to skew towards the older generation, and emissions just aren’t really a concern. Since EV fires tend to make the news a lot of the time, if they’ve got a perception that getting an electric tractor might cause a bushfire and burn their entire farm down, even if that’s very unlikely, and maybe even more likely with a diesel, I don’t think you’ll find them very willing

(This is specifically in regards to Australian farmers I’ve known, perhaps farms elsewhere are smaller, or farmers elsewhere a bit more willing to take upgrades)
