Daddy had one of the earliest 300`s i know of, ran it when i was 9. Then we went to Gleaner K2, then to F then to IH715, lost my axx farming with that one,, now back to a K Gleaner....... the old 300 was a gooden...... Didnt have the round 300 symbol. some kinda funky slash or arrow through the 300 symbol... had a 4 cyl diesel. remember when it wouldnt crank. we`d just pull it off to get it started.
