I just got a new to me ford 917, and ordered new blades from flailmaster. I went with the 2 piece blades for coarse cutting, but was wondering about staggering them. I don't think its set up properly now. It has 14 blades on each row. From what I am reading there should be 9 per row. Do I start out on the left side staggering them, then space each one on same row approx. 7 inches? This is a 60 inch cutter. Please excuse my ignorance on this machine. It sure seems like a well built machine. Thanks, Steve
