Flow Divider Control
The traction unit hydraulics (i.e., the traction drive,
loader arms, and attachment tilt) work on a separate
hydraulic circuit from the auxiliary hydraulics for
powering attachments; however, the two systems share
the same hydraulic pumps. Using the flow divider
control (Figure 10), you can vary the speed of the
traction unit hydraulics by diverting hydraulic flow to the
auxiliary hydraulics circuit. The flow divider allows you
to divide the flow of fluid in varying degrees to slow the
traction unit. Thus, the more hydraulic flow you divert
to the auxiliary hydraulics, the slower the traction unit
hydraulics will move.

• Move the flow divider control to the twelve o'clock
position to provide maximum speed to the traction
unit hydraulics.
Use this setting for fast operation of the traction unit.
• Move the flow divider control between the twelve
o'clock and nine o'clock positions to slow the
traction unit hydraulics and fine tune the speed.
Use a setting in this range with attachments
with hydraulics where you need to both run the
attachment and move the traction unit hydraulics,
such as the auger, boring unit, hydraulic blade, and
tiller.
• Move the control to the nine o'clock position to
transfer all hydraulic flow to the auxiliary hydraulics
of the attachment.
In this setting, the traction unit hydraulics will not
work. Use this setting with hydraulic attachments
that do not required the traction unit hydraulics.
There are currently no attachments that require the
nine o'clock position; however, the trencher does
work best if you set it close to nine o'clock so that
the traction unit will creep slowly when trenching.
Note: The flow divider control can be fixed in place
by turning the knob on the control clockwise until it
contacts the dial (Figure 10).

Parking Brake
The traction unit is equipped with a parking brake
(Figure 11). Rotate the brake lever downward to set the
brake to lock the rear wheels whenever the traction unit
will be stopped on a hill or left unattended. Move the
lever up before driving the traction unit.

Indicator Lights
The indicator lights warn you in the case of a system
malfunction and, in the case of the glow plug light,
indicate that the glow plugs are on. Figure 12 illustrates
the four indicator lights.
1. Oil pressure light
2. Battery light
• Engine Temperature Light
If the engine temperature light is on, the engine is
overheating. Stop the engine and allow the traction
unit to cool down. Check the coolant level and the
belts to the fan and water pump. Fill the coolant as
required and replace any worn or slipping belts. If
the problem persists, contact your Authorized Toro
Dealer for diagnostics and repair.
• Oil Pressure Light
This light is on for a few seconds whenever you
start the engine. If the oil pressure light is on while
the engine is running, the engine oil pressure is low.
Stop the engine and allow the traction unit to cool
down. Check the oil level and fill the crankcase with
