7240 planter marker drop

question for you guys is there a way to speed up how fast the markers on a JD7240 drop? its a 11 row set up for beans. it has hyd cylinder on each marker and when you lift the markers lift all on one hook up. looked at the book but did not see anything and my first time with this planter. thanks in advance.

Since nobody has responded I will take a wild shot at it. I have a plain 7200 12 row 30 Planter. I know that tracing hoses that disappear into the tongue and then from the tongue disappear into the planter frame is frustrating at best but there might be a restrictor somewhere in a marker hose. I have never messed with the marker drop on my 7200 but on the 6 row 7000 I used to have it seems like there was a hexagonal shaped fitting With a set screw to adjust the marker drop speed. It was in front of the frame on the left side of the tongue I think but it has been a long time since I had the 7000. By the way it sounds in your post the marker cylinders get oil from the same hoses that raise the planter. Come to think of it on my 7200 I have to force the markers down meaning if I push the hydraulic lever in the tractor into float the planter will go down but the markers will not go down. I have to hold the hydraulic lever in the down pressure position until the marker goes down. This tells me there is a valve somewhere in the planter that needs to be held open by hydraulic pressure to allow the markers to go down. Your planter probably has that big master cylinder in the tongue. I would trace hoses from that master cylinder to see if the marker lift hoses are in that area. There might be an adjustment there or maybe the markers will just have to be slow. Sorry I cant point you directly to something. I would look around that big master cylinder first though if hour planter has one.

I'm not familiar with your planter, so I'm suggesting things to try. I would think your operators manual should have something in it about adjusting the marker speed, but, they want them to go slow so you don't tear them off going to fast while lowering. That said, I had a White 5100 set up like yours. You had to hold the hydraulic lever to get the markers to drop and they were SLOW!! Probably go 20 or 30' before the marker hit the ground. When raising the planter, the marker would raise first and then the planter. I unhooked the marker hoses from the cylinder and ran seperate hoses for the markers, thus eliminating the issue. There is either an adjustment for the marker speed or else a restrictor in the lines to slow them down. If there is a restrictor, maybe you could take it out and drill a larger hole in it to speed it up. My advise is worth what you paid for it, hope this helps, Chris

thinks guys, what you guys said is what I have. the valve body on the planter I will see if I can do something there, in the bigger fields not a big deal but I have some small 4 and 5 acre fields also and is a pain.
