I watched this when I was little so there is not much i remember, but I’m sure it was a horror movie where eletronics just start attacking humans. I remember one scene where the characters where running away in the field from a tractor with theeee tractor tiller killing a person.
Sounds like a description of Maximum Overdrive
starring Emilio Estevez
from the story by Stephen King
Could it be “Pulse” (1988)
