live in Spfd, farm located NW Macoupin county | Without a doubt, get the 6 row. Low tin prefered.
However, I have seen some low tin on a high tin head. You need to check the serial numbers. There is a serial number break in the high tins where the left post on the back side was spaced out to clear the reverser on the 6620. The rear posts on the earleir heads wre not consistent in their position. To get them to clear on a 6620, some had to be completely cut out and moved over. Others, the post could be spilt, collapsed some with a big hammer and then welded to get the clearance needed. Check with your local JD dearler andthey should be able to tell that break. |
