Cub Cadet 3000
Bill of Materials
• 2 - 3000 P.S.I. Hydraulic Gauges
• 1 - 200 P.S.I Hydraulic Gauge
• 2 - 9/16-18 Straight Thread O-ring & JIC fitting (JIC
dependent on hose fittings)
• 3 - 3000 P.S.I. hoses of adequate lengths
(Connect as shown in FIG 1)
• 1 - T fitting
• 1 - needle valve
Connection Procedure
1. Remove tractor seat.
2. Remove both check plugs using a 1/4” hex drive.
3. Replace check plugs with the 2 9/16-18 straight
thread O-ring fittings.
4. Connect the T fitting and needle valve to the left
side. (Reverse Hi)
• Connect the 200 P.S.I. gauge to the needle
valve making sure flow can be shut off to this
gauge.
• Connect the 3000 P.S.I. gauge to the T fitting.
5. Connect another 3000 P.S.I. fitting to the right
side. (Forward high pressure port)
Hydrostatic Transmission Pressure Test Setup
FIGURE 1.
Forward ONLY Test Procedure
1. Lift tractor elevating rear tires off the ground.
(Tires will rotate)
2. Remove pin from parking brake. (allowing brake
to be apply while not in neutral)
3. Open needle valve allowing flow to the 200 P.S.I.
gauge (applying reverse can now damage this
gauge).

4. With tractor running, apply parking brake.
5. Continue holding the brake. depress the forward
foot pedal until max. pressure is seen on right
side gauge.
6. Record pressures from the 200 P.S.I. gauge and
the right side 3000 P.S.I. gauge.
Reverse ONLY Test Procedure
** To test for reverse side high pressure switch the
changes to opposite ports and repeat the similar to
the forward test. **
Conclusion
The 200 P.S.I. gauge sees the charge pressure in the
system, and during this type of the test the pressure
should be 20-40 P.S.I. The right side 3000 P.S.I.
gauge sees the forward high pressure and for this test
should read 1000 to 1400 P.S.I. If the gauges see
values close to this range the hydrostat is functioning
properly.
