Fault Phenomenon: John Deere 850K dozer front push blade raises unevenly, tilting left/right.

Troubleshooting Process:
– Checked flow divider motor: flow divider motor worn.
– Checked cylinders: one cylinder has internal leakage.
– Checked check valves: make-up check valves stuck.
– Checked mechanical: push blade linkage deformed.

Root Cause: The flow divider motor in the front push blade lift circuit is worn, causing unequal flow distribution to the two cylinders.

Required Parts: Flow divider motor assembly.
