I am interested in determining the minimum row spacing that can be obtained when modifying a JD 643 corn header for use in narrow rows. I would like to convert a 6-30" to a 9-20". Without any major modifications to the row units how narrow can they be set on a JD 643 header? Will a 643 header frame carry 9 rows without additonal stiffening? If not, what needs to be done to carry 9 rows. I presume that the answer will be the same for both the hi-tin and lo-tin series. We have an early model lo-tin header. I realize that we will have to modify the existing tin or buy new tin/plastic dividers.
It's been raining here in southern IL for the last three weeks, the soil is saturated, the creeks have been bank full or running over for the past week, the five day forecast shows rain every day but one and nobody has any crops planted. We're ready to plant, just need to be able to find some dry dirt and that won't be anytime soon. Starting to run out of things to do and thought I'd get a jump on researching a planned winter project. If you've done this before and know the answer I would appreciate your comments.
Thanks.
