[AT] One-way cylinder

[Al Jones]

Yes it will work that way.  That is how we ran hydraulic lift row
markers on the 2940 (same basic hyd. system as a 2640) in later years.
Left marker hose went in the left remote and the right marker hose
went in the right remote.  Push the little lever underneath the remote
to "lock" the port with the hose in it, leave the other lever in
neutral.  Left lever by the seat controlled left marker, right lever
controlled the right.I can't remember if the "up" port was the left
one or the right one on the remote but it worked well. Also can't
remember if it would float--there may be a setting on the spool valve
that has to be changed, can't remember. We moved up to a bigger
tractor on everything that had a separate hyd. circuit for the row
markers when I was in high school and the 2940 just grinds feed now.

Hope this helps
Al.

On my mower conditioner I have a cylinder that’s setup as a simple one-way cylinder. I’d like to keep it that way as I have a WD-45 I’d like to use on it at some point.

I assume I can plug it into the lift port to raise it and then drop the handle to the float position to bring it back down? I didn’t see anything in the manual that addressed this type of use.
