Procedure for Mow Circuit Pressure Test
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately ten
(10) minutes. Make sure the hydraulic tank is full.
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. Raise hood to allow access to mow control manifold.
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.
4. Install 5000 PSI (350 bar) pressure gauge with hy-
draulic hose attached to mow control manifold test port
for the mow circuit (front or rear cutting units) to be
tested (Fig. 37). Manifold test port G1 should be used for
the front reel circuit and G2 should be used for the rear
reel circuit.
5. After installing pressure gauge, start engine and run
at low idle speed. Check for hydraulic leakage and cor-
rect before proceeding with test.
6. Move throttle to high idle speed (2850 RPM). Make
sure that mow speed limiter is in the mow (4WD) posi-
tion. Release parking brake.
CAUTION
Cutting reel blades will rotate when lowered with
PTO switch in ON position. Keep away from cut-
ting units during test to prevent personal injury
from rotating reel blades. Do not stand in front of
the machine during test.
7. With seat occupied, engage the mow circuit. Watch
pressure gauge carefully while mowing with the ma-
chine.
8. Mow circuit pressure should be from 1000 to 3000
PSI (69 to 207 bar) and will vary depending on mowing
conditions.

9. Disengage cutting units and shut off engine. Record
test results.
10.After testing is complete, disconnect pressure gauge
from manifold test port. Install dust cap to test port fitting.
If necessary, repeat test for other mow circuit.
11. Lower and secure hood after all mow circuit pressure
testing is completed.
