Starting The Engine; Shutting Off The Engine; Raising Or Lowering The Cutting Units - Toro Groundsmaster 5900 Operator's Manual

surveying the site. Always use common sense
and good judgment when performing this survey.
•
Review the slope instructions listed below for
operating the machine on slopes and to determine
whether you can operate the machine in the
conditions on that day and at that site. Changes
in the terrain can result in a change in slope
operation for the machine.
•
Avoid starting, stopping, or turning the machine on
slopes. Avoid making sudden changes in speed or
direction. Make turns slowly and gradually.
•
Do not operate a machine under any conditions
where traction, steering, or stability is in question.
•
Remove or mark obstructions such as ditches,
holes, ruts, bumps, rocks, or other hidden hazards.
Tall grass can hide obstructions. Uneven terrain
could overturn the machine.
•
Be aware that operating the machine on wet
grass, across slopes, or downhill may cause the
machine to lose traction. Loss of traction to the
drive wheels may result in sliding and a loss of
braking and steering.
•
Use extreme caution when operating the machine
near drop-offs, ditches, embankments, water
hazards, or other hazards. The machine could
suddenly roll over if a wheel goes over the edge
or the edge caves in. Establish a safety area
between the machine and any hazard.
•
Identify hazards at the base of the slope.
If there are hazards, mow the slope with a
pedestrian-controlled machine.
•
If possible, keep the cutting unit(s) lowered to the
ground while operating on slopes. Raising the
cutting unit(s) while operating on slopes can cause
the machine to become unstable.
•
Use extreme caution with grass-collection systems
or other attachments. These can change the
stability of the machine and cause a loss of control.

Starting the Engine

1. Ensure that the parking brake is engaged.
2. Remove your foot from the traction pedal and
ensure that it is in the N
3. Turn the ignition key to the R
4. When the glow indicator dims, turn the ignition
key to the S
TART
5. Release the key immediately when the engine
starts and allow it to return to the R
6. Allow the engine to warm up at low speed
(without load) for 3 to 5 minutes, then actuate
the throttle switch to attain the desired engine
speed.
Important:
The starter motor automatically
disengages after 30 seconds to prevent
premature starter motor failure. If the engine
fails to start after 30 seconds, turn the key
to the O position, check the controls and
FF
procedures again, wait 2 minutes, and repeat
the starting procedure.
Note:
When the hydraulic-fluid temperature
is below 4°C (40°F), the machine operates in
a warm-up mode; limiting the engine speed
to 1,650 rpm and preventing traction-drive
operation in High range. When the fluid
temperature reaches 4°C (40°F), the warm-up
mode disables.

Shutting Off the Engine

1. Set the throttle switch to the L
2. Move the PTO switch to the O
3. Engage the parking brake.
4. Rotate the ignition key to the O
5. Remove the key from the switch to prevent
accidental starting.
Important:
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
complications.
Raising or Lowering the
Cutting Units
Raising the Cutting Units
1. While sitting in the operator's seat, start the
engine.
Note:
Whenever you are running the machine
at under 2,000 rpm (e.g., when you are running
the engine at low idle or transporting the
