This is a picture of the cab cooler I had on the 930 Case about 40 years 
ago. That white box on the roof contained the foam filters, fan and 
water tray and that is where the

evaporation process happened. Water was pumped up there by a 
temperamental little electric fuel pump that caused me no end of 
frustration when it would not start.

The water tank and pump can be seen mounted on one of the cab steps in 
front of the rear wheel. Excess water up top would return to the tank 
(until the exit hole in the tray

blocked up with mud). So the water got dirty from dust and the tank 
needed to be flushed and re filled every day in the hot weather. I was 
so happy to get real air conditioning

in the next tractor.

Ralph in Sask.
