The NTSB's narrative final · quoted from the NTSB record
While on an aerial application of fertilizer on a field, the pilot noticed that the engine temperature was high and engine oil was covering the windscreen. The 700-hour pilot initiated a precautionary landing to a nearby field with limited forward visibility. During the landing roll, the airplane struck a berm and the right main landing gear collapsed. Examination of the airplane revealed the oil was leaking from a seal at the base of one propeller blade at the propeller hub attach point.
