Procedure for Cutting Deck Circuit Pressure
Test
CAUTION
Prevent personal injury and/or damage to equip-
ment. Read all WARNINGS, CAUTIONS and Pre-
cautions for Hydraulic Testing at the beginning
of this section.
1. Park machine on a level surface with the cutting deck
lowered and off. Make sure hydraulic oil is at normal op-
erating temperature, engine is off and the parking brake
is applied.
2. Install 5000 PSI (350 bar) pressure gauge with hy-
draulic hose attached to manifold test port (G) for the
deck to be tested (Fig. 37).
CAUTION
Cutting deck blades will rotate when cutting
deck is lowered with PTO switch in ON position.
Keep away from deck during test to prevent per-
sonal injury from rotating blades. Do not stand in
front of the machine.
3. Start engine and increase engine speed to high idle
speed. Release the parking brake.
4. Watch pressure gauge carefully while mowing with
the machine.
5. Cutting deck circuit pressure should be as follows
and will vary depending on mowing conditions:
LH Wing Deck: 1000 to 3000 PSI (69 to 207 bar)
Center Deck: 1000 to 3000 PSI (69 to 207 bar)
RHWingDeck:1000to2000PSI(69to137bar)
6. Disengage cutting deck. Shut off engine and record
test results.
7. When testing is completed, disconnect pressure
gauge with hose from manifold test fitting. Secure dust
captotestfitting.
