I just got a woodchipper. It has a hydraulic feed consisting of a gear pump and hydraulic motor. Plus speed and direction control. A simple manual system, no servos or pilot valves.
Manufacturer recommends ISO 32 hydraulic oil. Is there any downside to using a tractor transmission fluid that's designed for the common sump? (that feeds the transmission & tractor hydraulic system)
The key difference is the hydraulic motor of the chipper. And the transmission & brakes of the tractor. Many tractors have a gear pump to pressurize the system. Yet, some farm implements (planter, baler, etc. ) use hydraulic motors that run from the tractor hydraulics.
I wonder if the friction modifiers for the tractor clutches & brakes causes an issue with the hydraulic motor swash plate.
Your thoughts and experience is appreciated.
