The pilot of the tailwheel-equipped airplane reported that, during an agricultural application flight, about 800 ft into the takeoff roll on a gravel airstrip, he veered the airplane to the right to avoid hay bales that were stacked on the left side of the runway. He added that, as the airplane veered right, the right-wing spray boom encountered tall wheat, and the airplane exited the right side of the runway. Subsequently, the airplane came to rest nose down.

The airplane sustained substantial damage to the left wing.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s abrupt maneuver to avoid hay bales during the takeoff roll, which resulted in a loss of directional control.
