If the output LED’s are on as specified, but the machine
does not function properly, this indicates a non–electrical
problem. Repair as necessary.
Note: Due to electrical system constraints, the output
LED’s for “START”, “PREHEAT” and “ETR/ALT” may
not blink even though an electrical problem may exist for
those functions. If the machine problem appears to be with
one of these functions, be certain to check the electrical
circuit with a volt/ohm meter to verify that no electrical
problem exists to these functions.
If each output switch is in the correct position and
functioning correctly, but the output LED’s are not
correctly illuminated, this indicates an ECU problem. If this
occurs, contact your Toro Distributor for assistance.
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 ACE, disconnect it from the
machine and 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.
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
S1 Front reel circuit
S2 Rear reel circuit
S3 Lift/lower front wing cutting units
S4 Lift/lower center cutting unit
S5 Lift/lower rear cutting unit
S6 Lower any cutting units
S7 Lift any cutting units
S8, S9 Backlap any cutting units
Operating Characteristics
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.
When operating the machine, always use the seat
belt and ROPS together.
Warning
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 the
machine is operated with a malfunction.
Mowing
Start engine and move throttle to FAST so engine is
running at maximum speed. Move the ENABLE/DISABLE
switch to ENABLE and use the LOWER MOW/RAISE
lever to control the cutting units (front cutting units are
timed to lower before the rear cutting units). To move
forward and cut grass, press traction pedal forward.
Transport
Move the ENABLE/DISABLE switch to joy stick
DISABLE and raise the cutting units 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 machine on slopes. Drive
slowly and avoid sharp turns on slopes to prevent roll
overs. The cutting units should be lowered when going
downhill for steering control.
Important Allow 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.
