I would like to add the hydraulic cylinder to the bob tach . Can I add on the cylinder and connect it to the hydraulic connections for attachments and run it that way?
I don't see why not.
You should check hyd pressure specs on bobtac before hooking to aux. Most are hyd release and spring locked that may cause an issue without the right hydraulic valving for the bobtac.
Welcome to the Forums Ronfire! You need check the hydraulic pressure on the aux. Standard Bobtach hydraulics are much weaker pressure wise than the aux's. The aux. probably have the power to break the handles/pins.
