If it is truly a #143 two valve tank system it will have power beyond provision for a third valve. The two valve system normally runs the blade and tilt. Third valve is for a ripper or single rear implement.
What is the unit s/n on the tank?
Thanks for the response. I have the original bill of sale and it lists the hyd control as a model 143, serial # 62G3809. I confirmed the serial number on the tank tag.
The 62G1-up series #143 has a single valve in the tank. An option for either a single or double spool remote valve was offered.
Can the single valve (in the tank) be set up for power beyond? Any idea of what would be involved?
As I stated there is provision for remote valve/s. Look on the back of the tank and you will see a jumper housing/plate. Remove this jumper and run lines to and from the remote valve. Cat did it with a bunch of fancy lines and flanges but no reason it can't be done with hose.
