Important: The display will show
eight (8) individual records with the fault
displayed on the 8th record. Each record
will be displayed for 10 seconds. Be sure

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 Diagnostic

reconnect loopback connector to harness
connector. Machine will not operate
without loopback connector installed on
harness. Store Diagnostic ACE in dry,
secure location in shop, not on machine.

Operating Tips

Familiarization
Before mowing grass, practice operating machine
in an open area. Start and stop the engine. Operate
in forward and reverse. Lower and raise cutting
units and engage and disengage reels. When you
feel familiar with the machine, practice operating
up and down slopes at different speeds.
The brakes can be used to assist in turning the
machine. However, use them carefully, especially
on soft or wet grass conditions because the turf
may be torn accidentally. Individual turning brakes
may also be used to help maintain traction. For
example, in some slope conditions, the uphill
wheel slips and loses traction. If this situation
occurs, depress uphill turn pedal gradually and
intermittently until the uphill wheel stops slipping,
thus, increasing traction on the downhill wheel.
