The pilot’s failure to maintain terrain clearance during a low-level aerial application flight, which resulted in impact with terrain and a subsequent forced landing. Contributing to the accident was the location of the spray boom pressure gauge, which required the pilot to divert his attention away from the airplane’s flight path, and the operator’s decision to locate the spray boom pressure gauge outside of the cockpit.
