Synopsis by Hal Erickson
We all know that Oliver (Eddie Albert) has had nothing but trouble with his farm's tractor, which behaves more like a bucking bronco when it chooses to behave at all. With this in mind, Lisa (Eva Gabor) decides that the perfect birthday gift for Oliver would be a brand new tractor. Thus, our heroine goes out and purchases the biggest tractor she can find -- and it's equipped with air conditioning and a stereo unit. To make sure Oliver doesn't tumble to the surprise, Lisa has the tractor delivered to the Ziffels -- and you can pretty much guess the rest!
