Other mistake: In the opening sequence Oliver stops the tractor in front of the house by pulling a lever. This lever is not a brake but is to engage a wheel to put a belt around to operate a threshing machine.

Older tractors had a hand clutch like that.

Other mistake: Mr. Haney is suing Oliver Douglas. While on the witness stand following a recess for lunch, Haney taps his right cheek and tells Judge Clemens, "You have some ketchup on your cheek." The Judge wipes his left cheek with a handkerchief.
Other mistake: A shallow tray of pancake batter is cooking on the stovetop. The coffee pot boils over and its round lid shoots into the air. Even though the lid would be extremely hot, Lisa catches it with both hands and uses it to cut four pancakes.
