Procedure for Cutting Deck Circuit Pressure Test (continued)
Hydraulic System: Testing
5. After installing pressure gauge, start engine and run at low idle speed. Check
for hydraulic leakage at tester connections and correct before proceeding
with test.
Keep away from cutting decks during test to prevent personal injury
from the cutting blades.
6. Sit on seat and operate the engine at high idle speed (2530 RPM). Release
parking brake and engage the cutting decks.
7. Watch pressure gauge carefully while mowing with the machine.
8. Cutting deck circuit pressure for front and left decks should be from 69 to 224
bar (1000 to 3250 PSI). Pressure for the right deck should be from 69 to 148
bar (1000 to 2150 PSI). Cutting deck circuit pressures will vary depending
on mowing conditions.
9. Disengage cutting decks and shut off engine. Record test results.
10. When testing is completed, disconnect pressure gauge with hose from
manifold test port.
11. Repeat test for other cutting decks if necessary.
