I'm looking at buying a 9275 Prowler. Currently the machine is set to go through 36" rows, center to center measurement of tires is 108". Dealer thinks we can flip the wheels to other side of machine to get it to widen to 120" OC. Thus would be ideal for 30" rows. Anyone try this or knows if this will work? Also, how tall of corn can you side/top dress with 9275, spinners look about 48" off ground and I've read 27" clearance. So I'm think 36" tall corn should be fine?
