3. For traction related problems (e.g. machine will not
goupanincline),considerperformingoneormoreofthe
following tests:
A. Charge Relief Valve Pressure.
B. Piston (Traction) Pump Flow.
C. Wheel Motor Efficiency.
NOTE: The piston pump used on Greensmaster Tri-
Flexmachinesisequippedwithreliefvalvesforboththe
forward and reverse direction. Due to engine output, it
is unlikely that traction pressure will reach relief valve
settings. If, however, a piston pump relief valve is leak-
ing or otherwise faulty, traction performance would be
affected.
4. For problems w ith the steering and lift/lower circuit,
consider performing one or more of the following tests:
A. Steering/Lift Relief Valve Pressure.
B. Lower Cutting Units Relief Valve (RV) Pressure.
C. Steering/Lift Circuit Gear Pump Flow.
D. Power Steering Valve.
5. For issueswith themowcircuit,considerperforming
one or more of the following tests:
A. Mow Circuit Gear Pump Flow.
B. Mow Circuit Relief Valve Pressure.
C. Reel Motor Case Drain Flow.
