What is the tightest (minimum) row spacing on those row crop headers?Can they be set at less than 30inch?
Only came in two sizes jaydee, 30 or 36/38 inch rows.
"x"53 is the 30 inch head, "x"54 is the wide row version. "x" stands for number of rows. Eg 653 or 654 etc. 12 row 30 (1253) was as wide as they went.
They can shave the ground if your land is reasonably flat. If it's up and down then I think you'd be better off with a flex head. What are you looking to harvest with them?
I wish they still made them, they were an awesome milo and sunflower head and we used them to do chickpeas a few times. The responses you got on NAT give a pretty fair rundown, most of those guys are corn/soybean growers. Like they said, lots of moving parts and upkeep but they work well.
