4. Individually, change each of the switches from open to
closed (i.e., sit on seat, engage traction pedal, etc.), and
note that the appropriate state of the switch changes.
Repeat this for all switches that you can change by
hand.
5. If a switch is closed and the appropriate indicator does
not change, check all wiring and connections to the
switch and/or check the switches with an ohm meter.
Replace any defective switches and repair any defective
wiring.
Note:
The InfoCenter display also has the ability to detect
which output solenoids or relays are turned on. This is a
quick way to determine if a machine malfunction is electrical
or hydraulic.
Verifying Output Function
1. Park the machine on a level surface, lower the cutting
units, stop the engine, and engage the parking brake.
2. Turn the key switch to the On position, but do not
start the machine.
3. Locate the appropriate output function in the
diagnostics menu on the InfoCenter.
4. Sit on the seat and attempt to operate the desired
function of the machine. The appropriate outputs
should change state to indicate that the ECM is turning
on that function.
Note:
If the correct outputs do not illuminate, verify that the
required input switches are in the necessary positions to allow
that function to occur. Verify correct switch function.
If the output displays are on as specified, but the machine
does not function properly, this indicates a non-electrical
problem. Repair as necessary.
Hydraulic Valve Solenoid
Functions
Use the list below to identify and describe the different
functions of the solenoids in the hydraulic manifold. Each
solenoid must be energized to allow function to occur.
Solenoid Function
SP2 Front reel circuit
SP1 Rear reel circuit
SVRV Lift/lower cutting units
SV1 Lift/lower front cutting units
SV3 Lift/lower rear cutting units
SV2 Raise any cutting units
Operating Tips
Familiarization
Before mowing grass, practice operating the machine in an
open area. Start and stop the engine. Operate in forward and
reverse. Lower and raise the cutting units and engage and
disengage the reels. When you feel familiar with the machine,
practice operating up and down slopes at different speeds.
Warning System
If a warning light comes on during operation, stop the
machine immediately and correct the problem before
continuing operation. Serious damage could occur if you
operate the machine with a malfunction.
Mowing
Start the engine and move the engine speed switch to the
Fast position. Move the Enable/Disable switch to the Enable
position and use the Lower Mow/Raise lever to control the
cutting units (the front cutting units are timed to lower before
the rear cutting units). To move forward and cut grass, press
the traction pedal forward.
Note:
Allow the engine to idle for 5 minutes before shutting
it off after a full load operation. Failure to do so may lead to
turbo-charger trouble.
Transport
Move the Enable/Disable switch to the Disable position and
raise the cutting units to the transport position. Move the
Mow/Transport lever to the transport position. Be careful
when driving between objects so you do not accidentally
damage the machine or cutting units. Use extra care when
operating the machine on slopes. Drive slowly and avoid
sharp turns on slopes to prevent roll overs. Lower the cutting
units when going downhill for steering control.
