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 8), 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.

3. 12 o'clock position
• 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.
4. 10 to 11 o'clock position
5. 9 o'clock position
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 8).

Parking Brake

The traction unit is equipped with a parking brake
(Figure 9). 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.

Oil Pressure Light
This light (Figure 10) 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 oil as needed. If the
problem persists, contact your Authorized Toro
Dealer for diagnostics and repair.
