Hi got a 12G s/n 3wco1303 Has a few issues with the hyd system Ripper power up ok labors the pump going down
Blade levers ok down will stall the motor if both are pulled up together . Circle has a delay of a moment before it signals to drive Done some research seems the ball resolver p/n 4T1860 that are found in all the control valves and the combination valve could be at fault .And an orifice p/n1T0936 looses its tail can also cause issues
