Accumulator, Pressure-Limiting Valve and Pressure Sensor for Float Control
IMPORTANT:
Every time the header is changed or the skid plates are installed/removed, have your John Deere dealer check and if necessary re-adjust the pressure charge of the lift system accumulator.
The accumulator has a volume of 0.7 L (0.19 U.S. gal).
