Know Your Controls
Choke
(Fig. 5)–To start a cold engine, move the choke
control forward to close the choke. After engine starts,
regulate choke to keep engine running smoothly. As soon
as possible, move the choke backward to open the choke. A
warm engine requires little or no choking.

Throttle Control (Fig. 5)–Throttle is used to operate
engine at various speeds. Moving throttle forward increases
engine speed; backward decreases engine speed. The
throttle regulates the speed of the sweeper reels and, in
conjunction with traction pedal, controls ground speed of
the sweeper.
Engine Oil Pressure Warning Light (Fig. 5)–Light glows
if engine oil pressure drops below a safe level while engine
is running. It light flickers or remains ON, stop machine,
turn off engine, and check oil level. It oil level is low, but
adding oil does not cause light to go out when engine is
restarted, turn off engine immediately and contact your
local Authorized TORO Distributor for assistance.
Ignition Key Switch (Fig. 5) – The key switch, which is
used to start and stop the engine, has three positions: OFF,
RUN, and START. Rotate key clockwise (START) to
engage starter motor. When engine starts, release key and it
will move automatically to the RUN position. To shut
engine off, rotate key counterclockwise to the OFF
position.
Fuse: (Fig. 5) – Provides 10 amps ignition circuit
protection. If fuse is blown the engine will not crank.
Hour Meter
(Fig, 5) – Indicates total hours of machine
operation. The hour meter starts to function whenever the
key switch is rotated to the ON position.
Reel PTO Engagement Handle
(Fig. 5) – The engagement
of the sweeper reels is done with the Reel PTO
Engagement handle. The handle also sets the height of the
fingers. There are two settings for finger height. The height
of the fingers is initially set so the fingers touch the top of
the turf. The first setting will set the fingers at 1–1/4 inch
from the surface. The second setting sets the fingers at
5/8 inch from the surface.
Hydraulic Vacuum Gauge
(Fig. 5) – When the hydraulic
oil filter becomes dirty, the vacuum level within the
hydraulic system will increase. Check vacuum gauge after
each day’s operation and before shutting off engine. (Refer
to Changing Hydraulic Oil and Filter)
Tow Valve Knob (Fig. 5) – The tow valve knob is located
in the front of the hydraulic pump. With the knob turned
fully clockwise the machine is in the operating position.
With the knob turned 1/2 turn counterclockwise the
machine is in towing position. After completion of mowing
operation, and before starting engine, close tow valve
securely by rotating fully clockwise. Do not exceed 5–8
ft.–lb. torque.
Parking Brake (Fig. 5)–Whenever the engine is shut off,
the parking brake must be engaged to prevent accidental
movement of the machine. To engage the parking brake,
pull back on lever. To release the parking brake push
forward on lever. Make sure parking brake is released
before moving machine. If the machine is parked on a
grade, make sure parking brake is applied.
Tilt Steering Lever (Fig. 6) – Lever on left side of steering
tower. Lift lever to adjust steering wheel to desired fore or
aft operating position and release lever to lock in place.
