Procedure for Piston (Traction) Pump Flow Test
This test measures piston (traction) pump output (flow).
During this test, pump load is created at the flow meter
using the adjustable load valve on the tester.
IMPORTANT: Traction circuit flow for your Reel-
master is approximately 30 GPM (113.5 LPM). Use 40
GPM Hydraulic Tester #AT40002 (pressure and flow)
for this test (see Special Tools in this chapter).
1. Park machine on a level surface with the cutting units
lowered and disengaged. Make sure engine is off. Apply
the parking brake. Make sure mow speed limiter is in the
transport position to allow full movement of traction ped-
al.
2. Read Precautions For Hydraulic Testing in this sec-
tion.

Before opening hydraulic system, operate all hy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
Relieving Hydraulic System Pressure in the Gen-
eral Information section of this chapter.
3. Make sure that traction pedal is adjusted to the neu-
tral position. Also, ensure that piston (traction) pump is
at full stroke when traction pedal is pushed into fully for-
ward position.
4. Raise and support machine so all wheels are off the
ground (see Jacking Instructions in Chapter 1 - Safety).
