4. Make sure that traction pedal is adjusted to the neu-
tral position. Also, ensure that traction pump is at full
stroke when traction pedal is pushed into fully forward
position.
5. Raise and support machine so all wheels are off the
ground (seeJacking Instructions inChapter 1 -- Safety).
6. Thoroughly clean junction of hydraulic hose and
right side fitting on bottom of traction pump (Fig. 36).
Disconnect hose from right side pump fitting.
IMPORTANT: Make sure that the oil flow indicator
arrow on the flow meter is showing that the oil will
flow from the pump, through the tester and into the
disconnected hydraulic hose.
7. Install tester with pressure gauge and flow meter in
series between traction pump fitting and disconnected
hose to allow flow from traction pump to tester. Use hy-
draulichosekit(seeSpecialToolsinthischapter)tocon-
nect tester to machine. Make sure that fitting and hose
connectionsare properlytightened.Also,make surethe
flow control valve on tester is fully open.
CAUTION

juring anyone near the machine.
8. Startengine and runat idle speed.Check for any hy-
draulic leakage from tester and hose connections. Cor-
rect any leaks before proceeding.
9. Move throttle so engine is running at high idle speed
(3200 RPM).
10.Slowly push traction pedal to fully forward position.
Keep pedal fully depressed in the forward position.
11.Have second person watch pressure gauge on test-
er carefully while slowly closing the flow control v alve
until 1000 PSI (69 bar) is obtained. Verify with a photo-
tac that the engine speed is still 3200 RPM.
12.Observe flow gauge. Flow indication should be
approximately 28 GPM (106 LPM).
13.Release traction pedal to the neutral position, open
flow control valve on tester and shut off engine. Record
test results.
14.If flow is less than 25 GPM (95 LPM), consider the
following:
A. The traction pump swash plate is not being ro-
tated fully (e.g. traction pedal linkage may need ad-
justment, mow speed limiter is not in the transport
position).
B. The piston (traction) pump needs to be repaired
or replaced as necessary.
C. Make necessary repairs before performing addi-
tional tests.
15.When testing is complete, disconnect tester and
hose kit from pump fitting and machine hydraulic hose.
Reconnect hose to pump fitting.
