Important: The Diagnostic ACE display must not be
left connected to the machine. It is not designed to
withstand the environment of the machine's every day
use. When done using the Diagnostic ACE, disconnect
it from the machine and connect loop-back connector
to harness connector. The machine will not operate
without loopback connector installed on the harness.
Store the Diagnostic ACE in dry, secure location in the
shop, not on the machine.

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 decks and engage
and disengage the mowers. 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 throttle to the Fast position.
Move the Enable/Disable switch to the Enable position and
use the Lower Mow/Raise lever to control the cutting decks.
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.
Function
Mow when the Grass is Dry
Mow either in the late morning to avoid the dew, which causes
grass clumping, or in late afternoon to avoid the damage
that can be caused by direct sunlight on the sensitive, freshly
mowed grass.
Select the Proper Height-of-Cut Setting
to Suit Conditions
Remove approximately one inch or no more than 1/3 of the
grass blade when cutting. In exceptionally lush and dense
grass you may have to raise the height–of–cut setting.
Always Start Mowing with Sharp Blades
A sharp blade cuts cleanly and without tearing or shredding
the grass blades like a dull blade. Tearing and shredding
causes the grass to turn brown at the edges which impairs
growth and increases susceptibility to diseases. Make sure
blade is in good condition and a full sail is present.
Check Condition of Deck
Make sure that the cutting chambers are in good condition.
Straighten any bends in the chamber components to ensure
the correct blade tip/chamber clearance.
After Operating
To ensure optimum performance, clean the underside of
mower housing. If you allow residue to build up in mower
housing, cutting performance will decrease.
Transport
Move the Enable/Disable switch to the Disable position and
raise the cutting decks 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 decks. Use extra care when
operating the machine on slopes. Drive slowly and avoid
sharp turns on slopes to prevent roll overs. Lower the cutting
decks when going downhill for steering control.
