While the Cross valve pictured MAY work, it is NOT the same valve used by OEM's and Deere. The ports look different also. Just look at the number of ports on that valve (3) and compare to the number of ports on your JD valve. The cross valv looks like it is for single acting cyclinders. The description says it can be used on double acting cylinders (most US planter markers) but I sure don't see how without a lot of extra plumbing and maybe a second valve. Be careful. If it looks to good to be true it probably is.
