Outside, at the back of the Antique Farm Equipment demonstration area, brothers Josh Parks, 35, and Zak Parks, 30, are working on the engine of a 1938 McCormick-Deering tractor, trying to get it running. They’ve been working on it since Sunday.
They’ve overnighted a head gasket from a specialty supply company. They’ve replaced a valve, but it’s still not running. Josh cranks hard at the hand crank at the front of the tractor. No go.
The two men’s expressions and focus on the task at hand are as intense as any brain surgeon’s.
