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).

Recommended pressure for 55 mm (2.17 in.) hydraulic cylinder diameter:

Header kPa bar psi
918 (Flex) 7000 70 1015
920 8000 80 1160
922 8500 85 1233
925 9000 90 1300

 

Recommended pressure for 60 mm (2.36 in.) hydraulic cylinder diameter:

Header kPa bar psi
918 (Flex) 6000 60 870
920 7000 70 1015
922 8000 80 1160
925 8500 85 1233

 

NOTE: The pressures shown in the table are depending on header type and equipment.

The accumulator is maintenance-free and cannot be repaired if damaged.
