Other mistake: Once Earl stops the CAT at Burt and Heather's house, Val is standing on its roof directly above Earl. Val is looking and talking straight at them. The graboids shake the CAT, Earl drives it forward quite a bit (take notice just how far), but he looks up to tell Burt to hurry but he and Val are still facing in the same direction. They should be facing backward due to the distance they had to move up. Also, you'll notice that Burt is right in line with the trailer as he throws most of his gear. (01:14:30 - 01:15:30)

Revealing mistake: Near the end, Val, Earl and Rhonda are way off the rocks after the blast. When the monster comes up out of the ground and Val takes off, you can see the "ground" bounce. It's definitely a false ground so they can get the "graboid" pushed up through it. (01:24:10)
Earl Bassett: What kind of fuse is that?
Burt Gummer: Cannon fuse.
Earl Bassett: What the hell you use it for?

Chosen answer: The machine is a vibrating case cleaner, which is used to polish the brass casings of pistol and rifle ammo. The "dirt" is actually an abrasive polishing compound.
