TEST NO. 4: Lift Circuit Pressure
1. Make sure hydraulic oil is at normal operating temper-
ature before doing test.
2. Lower cutting units, engage parking brake and stop
the engine.
3. Raise seat to get access to hydraulic test fittings. Re-
move access cover from in front of hydraulic valve block.
Install a 5000 PSI gauge with extension hose onto quick
disconnect fitting in port G1A. Put gauge and hose
through opening in front of hydraulic valve block, then
lower the seat.
4. Sit on the seat and start the engine. Move throttle to
full speed (approx. 2500 RPM for 6500–D and 2750
RPM for 6700–D).
5. While sitting on the seat, pull “Lower–Mow/Raise”
control lever back to the RAISE position to lift the cutting
units. Hold the lever in the RAISE position while looking
at the gauge.
GAUGE READING: 2750 +/– 150 PSI.
6. Stop the engine. If pressure is too high or low, check
charge pressure and adjust as necessary (charge pres-
sure affects lift pressure). If pressure is too high, remove
cap on relief valve R2A and adjust screw to get correct
pressure. If pressure is too low, remove cap from relief
valve R2A and adjust screw to get correct pressure. If
pressure is still too low, pump or lift cylinder(s) should be
suspected of wear, damage or inefficiency.
