Get a cat… or a few cats
We wish it were more complicated than this but many people have success with cats, though anybody who has had more than one cat can tell you that every cat’s attitude toward catching rats or mice is different. Some will relentlessly hunt the mice while others will just sit on your tractor seat and sleep. So, if you’re going this route, try letting your cats sleep in the area where your equipment is. Hopefully they won’t destroy your seat.
As for this photo, okay, you’ve got us. We may or may not have photoshopped the rat on top of the tractor. So don’t come down too hard on the cat for napping on that soft swivel seat.
