I’ve always wondered why Rick ‘n the gang don’t fire up some heavy equipment when they need to take out the rotters on an industrial basis. And why didn’t they just blow the road to that quarry and then take them out at leisure?
Farm equipment. Check out swathers, power rakes, combines and corn choppers. But they would be prone to clogging based upon the decay of the bodies. Fresh zombies would be more likely to clog versus a zombie that is several months along in the decay process.
Then there’d be no convenient plot device for later.
I never watch that show but it seems to me that a flamethrower would be the perfect anti-zombie weapon. You can keep your distance, and since they’re bunched together one flaming corpse would likely ignite surrounding zombies etc.
