Help with title, please!
 

In this late 60's--early 70's film, the undead are gradually claiming their victims. The only scene I can recall halfway clearly has one character frantically running after a tractor which is spraying a field in the middle of the night in order to warn the tractor driver (great backlit shot of the spray.)
After finally catching up, we see that it is too late; the driver is slumped over, with a telltale dark brown egg-shaped mark on the neck. I think the tractor must have been on autopilot.
I saw this in high school, and have wondered off and on about it for years.
Any ideas?

Night of the Hickies (1976)

Here's an idea......:D
