I am looking to add a thrid valve to my 3720(no cab). I will be using it for power angle on a loader mounted plow. I am looking for the JD part numbers and to see what other people have paid for the kits I need. Thanks for the help.
post 2011 units use the eh version whith the handy switch in the joystick lever is lvb26030 ret $977.
pre 2011 units uses a mech op valve, lvb25506 $244. Typically you can not expect too much discount from an individual sales bundle.
There has been some discussion here about using the later eh kit on earlier tractors but I don't know if anyone has accomplished yet. Good Luck
You may also want to look into Deeres 3rd function hydraulic line kit - BW15630. It runs around $360. This includes hardlines and quick couplers that mount on the loader arm near the bucket.
