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. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine under load for
approximately ten (10) minutes. Make sure the hydrau-
lic tank is full.

2. Park machine on a level surface with the cutting units
lowered and off. Shut off engine. Make sure mow speed
limiter is in the transport position to allow full movement
of traction pedal.
3. 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.
