There is a hydraulic block /tap on the B7200 I have recently come upon. The handbook suggests that it is to be use when fitting a loader etc, and to be sure to move the switchable valve control back to the normal position when the implement is dismounted.
I've had a look at the parts layout, and it appears the hydraulic block is composed if a pressure relief valve controlled by a shimable spring, and a selector valve to redirect flow.
I would like to better understand this control valve. What I would like to do is redirect flow to a multi spool control valve with power beyond returning to the hydraulic valve to continue flow to the 3pth lift.
Anyone BTDT? or at least provide useful commentary?
I have seen reference to exchanging the B7200 valve with the unit from a B7800. Much more sophisticated, but I've not studied just what that entails or offers (except Power steering, which this tractor does not need).
TIA
