The battery isolators on Ag kit all have a KAM bypass that keep the vital ECU's on line or at least the memory and configurations ..... you are correct though in that it allows them to be parked for months and not drain battery power but the ECU "handshake" around the CAN takes much less than a minute even after several months and as engine start is now ECU initiated the thing won't start if it's not happy everything is online.... The current Range Rover is very slow to come on line after start and frequently not all of it does.....
A lot of AG kit now has EPL or Electric park brakes .
Don't think on any EPL system car, truck, or AG disconnecting the power releases the EPL ....they are all fail safe hence need power to release....... unlike the wife's old TVR that braked on the rear discs so if she parked it after an enthusiastic drive with hot brakes as the discs cooled so the handbrake would loose grip and off would roll Trevor
If you look at the value of a low spec tractor new it is more than many high end cars and higher spec farm kit is in mainstream super car price range ....as you say most higher spec farm kit now reports to the factory and dealer / user
You might know the answer to this?
I rent a bit of land off the local farmer and he was spraying something or other on the field out the back of my place the other day. The sprayer didn’t seem to be working evenly so I mentioned this when he pulled up for the usual chat/ brew.
He said it was working perfectly and that the field had been satellite imaged and the data loaded to the sprayer and was hooked into a SatNav so that the amount of shit sprayed matched the amount needed, presumably patchy bits get a bit more?
Is this actually a thing? Is that technically possible?
If so, Wow!
