Back in the winter I purchased a tree cutting head that was orginally supposed to be used for a feller buncher but I wondered if it could be mounted to an excavator and use it for land clearing. I got a hell of a deal on the head is another reason I decided to buy it and it was in great condition. I had to fabricate new bushings and a mounting plate to get the head to fit on my excavator stick but I did get it mounted and it works great. Its now down at the hydraulic shop getting all the lines and valves put on the excavator to run the head unit. My excavator is a Deere 892D-LC. The head unit does not have rotate but has grapple arms which need 12gpm I believe and the saw disc needs 30gpm flow and both are to be at 4000psi pressure. Does my excavator have the pump capacity to run the head unit and still have other stick functions though maybe at a slower speed? Or do I need a bigger hydraulic pump?
