Which Hydraulic Tests Are Necessary?
Before beginning any hydraulic test, identify if the prob-
lem is related to the traction circuit, mow circuit, lift/lower
circuit, steering circuit or engine cooling fan 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
Charge Pressure, Traction Circuit Relief Pressure, Rear
Traction Circuit Relief (RV) Pressure, Traction Circuit
Reducing Valve (PR) Pressure and/or Piston (Traction)
Pump Flow.
2. If a PTO circuit problem exists, consider performing
one or more of the following tests: Mow Circuit Pressure,
Mow Circuit Relief Pressure, Cutting Unit Motor Case
Drain Leakage and/or Gear Pump P1 and P2 Flow.

3. If a lift/lower circuit problem exists, consider perform-
ing one or more of the following tests: Lift/Lower Circuit
Relief Pressure, Lift Cylinder Internal Leakage and/or
Gear Pump P3 Flow.
4. If a steering circuit problem exists, consider perform-
ing one or more of the following tests: Steering Circuit
Relief Pressure, Steering Cylinder Internal Leakage
and/or Gear Pump P3 Flow.
5. If an engine cooling fan circuit problem exists, con-
sider performing one or more of the following tests:
Cooling Fan Circuit and/or Gear Pump P4 Flow.
