Procedure for Cutting Deck Circuit Pressure Test:
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately 10
minutes.
2. Park machine on a level surface with the cutting units
lowered and off. Make sure engine is off and the parking
brake is engaged.
3. Read Precautions for Hydraulic Testing.
4. Remove plug from hydraulic manifold port (G1).
5. Install test gauge with hydraulic hose attached to the
manifold port (G1).
CAUTION
Keep away from decks during test to prevent per-
sonal injury from the cutting blades.
6. Start engine and move throttle to full speed (3050 +
50 RPM). Engage the cutting units.
7. Watch pressure gauge carefully while mowing with
the machine.
8. Cutting circuit pressure should be from 1000 to 1500
PSI and will vary depending on mowing conditions.
9. Disengage cutting units. Shut off engine.
10.Disconnect test gauge with hose from manifold
block. Reconnect plug to the hydraulic manifold port
(G1).
