Anybody have any knowledge of a 3rd function valve for a John Deere tractor. I was thinking about getting a snow blade or maybe a grapple for the quick attach bucket on a John Deere 5510 and I know they require a 3rd function valve unless I want to run 20 foot of hose to rear hydraulic remotes. My tractor has the mid mount hydraulics and the joystick controls the bucket. I went to John Deere today and they said they did not sell a 3rd function valve kit for a model 5510 tractor. I thought that was odd....
