Which Hydraulic Tests Are Necessary?
Before beginning any hydraulic test, identify if the prob-
lem is related to the traction circuit, cutting (mow) circuit,
lift circuit or steering circuit. Once the faulty system has
been identified, perform tests that relate to that circuit.
1. If a traction circuit problem exists, consider perform-
ing one or more of the following tests: Traction Circuit
Relief Pressure, Traction Circuit Charge Pressure, Gear
Pump (P3) Flow, Wheel Motor Efficiency and/or Piston
(Traction) Pump Flow Tests.
2. If a cutting (mow) circuit problem exists, consider
performing one or more of the following tests: Relief
Valve (R1) and (R2) Pressure, Gear Pump (P1) and (P2)
Flow, Reel Drive Motor Efficiency and/or Reel Drive Mo-
tor Cross--Over Relief Pressure (Reelmaster 5510 and
5610) Tests.

3. If a lift circuit problem exists, consider performing
one or more of the following tests: Lift Relief Valve (R6)
Pressure, Gear Pump (P4) Flow and/or Lift Cylinder In-
ternal Leakage Tests.
4. If a steering circuit problem exists, consider perform-
ing one or more of the following tests: Steering Relief
Valve (R10) Pressure, Steering Cylinder Internal Leak-
age and/or Gear Pump (P3) Flow Tests.
