To the OP how many row planter and does it have cable style markers or a cylinder on each.

My 7200 6 row standard planter came with markers T'eed into lift cylinder. Planter and marker raised with one remote. Marker actuator inside main toolbar cycled and then planter lowered and other marker came down. Marker always tended to start raising before planter. Crossing waterways was a pain. Raise planter and marker immediately came up cross water way would need to stop, lower planter, wrong marker went down, lift and lower again to get right marker back down plus marker was always slamming hard on stops when raising. Adjustment on main frame is for rate of drop only. Raise is controlled by orifice size.

I think this is what you are wanting linked to.

I decided to separate the functions since I had 2 remotes and add a controllable valve that is controllable in one direction and full flow in the other. Now 2 hoses control lift and lower of planter cylinder and a single hose in the other outlet cycles the makers up and down and is fully adjustable in how fast it raises.

Now when I come to the water ways I can lift planter and the correct marker stays down tracking through waterway, cross waterway, and lower planter again all without stopping and cycling the planter each time to get the correct marker.

Also the flow control valve is adjustable so I can have the marker raise nice and slow without slamming around and into the stop.

Some previous threads. Video links included showing difference.
