We have a 23 unit JD 2510H applicator. In it's factory configuration, it has 2 adjustable down pressure controls, one for the left half of the machine, one for the right half. However, since we follow the tractor/planter tracks of a 24r planter, we find the center section needed a little more down pressure in some soil conditions to compensate for the deeper planter wheel tracks. However, doing that also increased pressure on the remaining wing units which often ran in non-tracked soil & created too much down pressure. So after looking at the cylinder & control valve arrangement for a few minutes, we decided that it would be easy to tie the 2 center cylinders together & separate them from the remainder of the openers. The wing unit openers then all became controlled by the remaining control valves. The only parts needed/used were 4 hoses approx. 36" long, 2 JIC tees, & 2 JIC caps, & some tye wraps. The machine could probably be restored to factory configuration in 10 minutes if desired. Nothing was removed.

Now those 2 cylinders are joined together & separate from the rest of the units & controlled by their own flow valve. The system could be returned to factory setup in probably 10 minutes or less. Parts needed are 4 hoses approx. 36" long, 2 JIC tees, & 2 JIC caps & some tye wraps.
