You could make a horizontal slidebracket, or similar mounting bracket that has two different settings for each tractor, this would be a big help for inexperienced operators, just put the front tire on the edge of the foam and drive. Actually, where you have it now, with your 8' drill width it should be close to the steering tire on your bigger tractor? However, if you are driving left or right on a slope also makes several inches of difference vs. a level field, which the operator needs to take into account. My front steering tires are several feet in from the last pass with my 10' notill drill, but after many years of planting it's like keeping a vehicle in the middle af your lane on the road, you just kindof get a feel for where to drive to get a correct row spacing, but the foam system will be more accurate. Traditionally, growing up on a farm, the dads did all the planting and left the tillage and mowing to us lowlevel help, and that's kind of how I still operate with my food plots. I've found having free helpers doing seeding can be more things to fix than it's worth.
