I called Reynolds in Atlanta Indiana and they sent me all the hardware to do it. When I’m done I’ll post pics. I’ll share this email about the same topic.
The planter I had was a 12 row 30" non folding. It had one master cylinder and 6 lift cylinders. I liked how the master system worked until it started giving problems, that is was nothing but trouble. The divider worked well and the lift speed was the same or faster as with the master cylinder. The drop speed might have been a little slower but not a lot. I remember having to adjust the rephasing relief valve on the divider but it was not a big deal. I am not sure how the plumbing on a 16 row would work, you said there were 2 master cylinders? I guess as long as there were the same amount of lift cylinders plumbed to each side of the divider it would work the same. I am assuming this is a front fold? Is the fold function tied into the master? Does the rear have to lift separate to get the wings to fold forward? In that same thread there was a guy who had made limiting brackets for his lift cylinders so they couldn't overextend. I didn't have that and didn't need it. I didn't have any issues with them going up too high. The newer planters may be different so that might be something to think about on yours.
