Before Operating
• Read and understand the contents of this Operator’s
Manual before operating the machine. Become familiar
with all of the controls and know how to stop quickly. A
free replacement manual is available by sending the
complete Model and Serial Number to The Toro
Company, 8111 Lyndale Avenue South, Bloomington,
Minnesota 55420-1196.
• Never allow children to operate the machine. Do not
allow adults to operate machine without proper
instruction. Only trained operators who have read this
manual should operate this machine.
• Never operate the machine when under the influence of
drugs or alcohol.
• Keep all bystanders away from the operating area.
• Keep all shields and safety devices in place. If a shield,
safety device, or decal is illegible or damaged, repair or
replace it before operation is commenced. Also tighten
any loose nuts, bolts, and screws to ensure that the
machine is in safe operating condition.
• Do not operate the machine while wearing sandals,
tennis shoes, sneakers, or shorts. Also, do not wear
loose fitting clothing which could get caught in moving
parts. Always wear long pants and substantial shoes.
Wearing safety glasses, safety shoes, and a helmet is
advisable and required by some local ordinances and
insurance regulations.
– Do not drive close to a sand trap, ditch, creek, or
other hazard.
– Reduce your speed when making sharp turns and
when turning on hillsides.
– Avoid sudden starts and stops.
– Before backing up, look to the rear and ensure that
no one is behind the machine.
– Watch out for traffic when near or crossing roads.
Always yield the right-of-way.
• Stay away from the discharge area when the machine is
operating. Keep all bystanders away from the discharge
area and don’t direct discharge toward bystanders.
• If the engine stalls or the machine loses headway and
cannot make it to the top of a slope, do not turn the
machine around. Always back slowly straight down the
slope.
• Do not take an injury risk! When a person or pet
appears unexpectedly in or near the operating area, stop
operation. Careless operation, combined with terrain
angles, ricochets, or improperly positioned guards can
lead to thrown object injuries. Do not resume operation
until the area is cleared.
• Lower the brush to the ground and remove the key from
the ignition switch whenever the machine is left
unattended.
While Operating
• This product may exceed noise levels of 85 dB(A) at
the operator position. Hearing protection is
recommended for prolonged exposure to reduce the
potential of permanent hearing damage.
• Optional attachments may impact the operating
characteristics of the traction unit. For example, slopes
that have been mowed with cutting decks may be unsafe
to travel on with a narrow attachment, such as a brush,
due to the loss of support and stability provided by the
width of the decks. Further, the decks may have
prevented the traction unit from coming too close to
holes, dips, drop offs, obstacles and uneven terrain
which may cause a roll over. Use extra caution when
operating a traction unit with a brush attached in place
of mowing decks.
• Using the machine demands attention. To prevent loss
of control:
– Operate only in daylight or when there is good
artificial light.
– Drive slowly and watch for holes or other hidden
hazards.
Maintenance
• Remove the key from the ignition switch to prevent
accidental starting of the engine when servicing,
adjusting, or storing the machine.
• Perform only those maintenance instructions described
in this manual. If major repairs are ever needed or
assistance is desired, contact an Authorized Toro
Distributor.
• Be sure that the machine is in safe operating condition
by keeping nuts, bolts, and screws tight. Check all bolts
and nuts frequently to be sure that they are tightened to
specification.
• Make sure all hydraulic line connectors are tight and all
hydraulic hoses and lines are in good condition before
applying pressure to the system.
• Keep your body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not your hands, to search for
leaks. Hydraulic fluid escaping under pressure can have
sufficient force to penetrate the skin and cause serious
injury. Seek immediate medical attention if fluid is
injected into skin.

Page 4
• Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the cutting
units and attachments to the ground.
• If the engine must be running to perform a maintenance
adjustment, keep hands, feet, clothing, and any parts of
the body away from the cutting units, attachments, and
any moving parts. Keep everyone away.

Check Chain Tension
New chains will stretch during the first few days of
operation, therefore; check chain tension frequently. If
chain requires adjustment, refer to Adjusting Chain.
Check Castor Wheel Tire
Pressure
Castor wheel tires to be inflated to 50 psi.
Important Before the rotary brush is operated, it must
be greased to assure proper lubricating characteristics: refer
to Lubrication section of manual. Failure to properly grease
the unit will result in premature failure of critical parts.

Page 13
Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Warning
Adjust castor height for proper brush ground pressure. The
castor wheel height is adjustable from 4 to 7 inches in 1/2
inch increments by adding or removing an equal amount of
spacers from each castor wheel.
1. Start engine and raise brush. Stop engine after brush is
raised.
2. Remove cap securing castor spindle to frame bracket.
Thrown debris has considerable force and could
cause injury.
• Stay away from the sweeping area when the
machine is operating.
• Keep bystanders away from the sweeping area
when the machine is running.
Operation
1. Lower the brush to the ground ensuring the lift circuit is
in the float position. The float position is engaged by
moving the center lift lever forward and releasing it to
return to the neutral position.
2. Increase engine speed to full throttle position.
3. Engage PTO switch.
4. Drive traction unit at a slow, comfortable speed.
Operating Tips
You can add measurable sweeping hours to your brush by
remembering these simple things:
1. More pressure doesn’t give a better sweep.
2. A level brush lasts longer.
3. Faster ground speed will cause the brush to wear faster.

2. Thrust washers
3. Move desired amount of spacers to top or bottom of
bracket. Make sure spacers are equal on both castor
wheels and a thrust washer is positioned on each side of
frame bracket.
4. Install cap and lower brush.
3. Spacers
Adjust Brush Down Pressure
Improper downward pressure can decrease brush life up to
95% (depending on the incorrect amount of pressure).
A brush sweeps with the tips of its bristles. When too much
down pressure is applied, the brush is no longer using it’s
tips; the brush is now working with the sides of the bristles.
This limits the flicking action of the bristles and limits it’s
sweeping effectiveness.
To check for correct downward pressure, operate brush on
the ground, rotating at normal operating speed with traction
unit remaining stationary. Stop operation, raise brush and
measure width of swept path. A properly adjusted brush
will have a sweeping path width of 2”–4”.
Ground Speed
Bulldozing produces a side thrust and excessive stress on
the brush, core and frame. While operating under the plow
effect, the bristles are flexed against the steel ring which
holds them and, eventually, this flexing will break the
bristles from the ring.
If ground speed is too fast, debris will pile up in front of
brush causing brush to bulldoze instead of sweep. This can
damage not only the brush, but also the core, chains,
sprockets, drive lines and frame.
Switch Operation
One switch will rotate the brush to the right and the other
switch will rotate the brush to the left. The brush must be
on the ground and rotating to change the angle of operation.

Page 14
Maintenance
The rotary brush has (12) fittings that must be lubricated
(Fig. 19).
Note: Determine the left and right sides of the machine
from the normal operating position.
Greasing the Brush
The rotary brush must be lubricated regularly. If machine is
operated under normal conditions, lubricate bearings and
bushings with No. 2 general purpose lithium base grease
after every 8 hours of operation or daily, whichever comes
first. Lubricate fittings immediately after every washing.
• Castor shaft bushings (2)
• Axle shaft bearings (2)
• Right and left lift arms (2)
• Right and left brush arms (4)
• Pivot pin (1)
• Cylinder pivot (1)

Adjusting Chain Tension
Make sure chain is properly tensioned to assure proper
operation of the machine and unnecessary wear. Check
chain tension by pressing side of chain at mid span of drive

Servicing Bumper Bushings
Servicing Castor Wheel And
After many hours of operation, the bushings pressed into
the top and bottom of the bumper will wear. To check the
bushings, move castor fork fore and aft and from side to
side. If castor spindle is loose in the bushings, bushings are
worn and must be replaced.
1. Start traction unit and raise brush to highest possible
position and turn off engine. Block up brush frame so it
cannot accidentally fall.
2. Remove locking cap, thrust washers and spacers from
top of castor spindle.
3. Pull castor spindle out of bumper. Allow thrust washers
and spacers to remain on bottom of spindle.
4. Insert pin punch into top or bottom of bumper and drive
bushing out of tube (Fig. 23). Also drive other bushing
out of bumper. Clean inside of bumper to remove any
dirt.

Bearing
The castor wheel rotates on a high–quality roller bearing
and is supported by a spanner bushing. Even after many
hours of use the bearing wear will be minimal. A wobbly
castor wheel usually indicates a worn bearing.
1. Remove locknut from capscrew holding castor wheel
assembly in castor fork. Grasp castor wheel and slide
capscrew out of fork.

Repair by an Authorized Toro Distributor or Dealer is your sole
remedy under this warranty.
Neither The Toro Company nor Toro Warranty Company is
liable for indirect, incidental or consequential damages in
connection with the use of the Toro Products covered by this

below, if applicable, there is no other express warranty. All
implied warranties of merchantability and fitness for use are
limited to the duration of this express warranty.
