"You Can't Cheat a Honest Man". From season one, this episode debuts the McCoy's Ford tractor at run time 7:50. It appears to have a NAA type hood ornament, but has smooth axle flanges with no nut. Its definitely a 4 speed. In subsequent episodes the tractor is a 860 with Power Steering. Notice the specs on the engine that Pepino reads to Grandpa Amos. SoS.
