START UP & PROPELLING
This model of broom is hydrostatically driven. Motion is achieved by depressing the foot pedal on the
floor board to the right of center. Letting the foot pedal up will result in a braking action caused by the
hydraulic system. This is the proper method for braking on this machine. The brake pedal on the left side
of the floor board should not have to be used except in cases where the engine has died or there is a
problem with the hydraulic system. To maintain operability, occasional use of brake system is advised to
prevent rusting and seizure of components in place.
1. Turn the key switch to the start position, all the way to the right. Add fuel as necessary using the
hand operated locking throttle. Release the key switch when the engine starts. Do not use ether
(STARTING FLUID) in this engine, severe engine damage will occur.
2. Use the foot pedal on floor board to choose the direction of forward or reverse.
3. After the desired direction has been selected, raise engine R.P.M. to about half throttle. Release
parking brake. Slowly depress control pedal and adjust the engine to the desired travel speed.
Speed can also be varied by the distance the control pedal is depressed.
4. To stop the engine, turn the key back to the center position. The parking brake must be set prior
to leaving the operator’s seat.
NOTICE
DO NOT REVERSE THE DIRECTION OF TRAVEL WHILE THE BROOM IS IN MOTION. THIS WILL
DAMAGE THE DRIVE COMPONENTS AND VOID THE WARRANTY. THIS TYPE OF OPERATION IS
CONSIDERED ABUSE.
WARNING
BEFORE STARTING ENGINE, BE SURE PARKING BRAKE IS SET, LEFT FOOT IS ON THE BRAKE PEDAL
AND RIGHT FOOT DOES NOT CONTACT THE CONTROL PEDAL. FAILURE TO DO SO COULD CAUSE
UNINTENDED MOVEMENT OF VEHICLE RESULTING IN INJURY OR DEATH.
!
CAUTION
Persons should ride in the seat properly wearing their seat belt whenever the vehicle is moving or in the vicinity of
other moving vehicles. Otherwise, they are much more likely to suffer serious bodily injury in the event of sudden
braking or a collision.
When using the seat belts, observe the following:
- Be careful not to damage the belt webbing or hardware. Take care that they do not get caught or pinched in the
seat.
- Inspect the belt system periodically. Check for cuts, fraying, and loose parts. Damaged parts should be replaced.
Do not disassemble or modify the system.
- Replace entire belt assembly (including bolts) if it has been used in a severe impact.
- Replace belt assembly after 3 years of use and 5 years of manufacture.

TOWING PROCEDURES
1. Before towing this machine check the following:
A. The tires should be inflated to 32 PSI and be in good condition.
B. Any loose items on the machine should be removed or secured.
C. Check to see that all the lug nuts/bolts are tight on the wheels and that the wheels are in good
condition.
2. The Parking Brake must always be set before starting to hook up the machine to a towing vehicle.
The Parking Brake must also be set before starting to unhook the machine from a Towing Vehicle.
3. Flip switch for Hitch on Dash
4. Drive Broom behind Vehicle (Leave about 5’ feet between vehicle and broom)
5. Lower hitch on to ball (Have one person guide you if possible)
6. When hitch is on, Power down with control valve (Where tire is about 6” off ground)
7. Put shaft pin in hole to secure
8. Unlock hubs on the rear wheels of the machine so that it will roll freely without turning the hydraulic
motors.
9. Open 1/4” ball valve on hitch for brakes.
10. Hook up the lights and make sure they are in good working order.
11. Hook up tow chain
12. Reverse procedure for unhooking.
13. Release the Parking Brake. Pull the machine a short distance and make sure the machines brakes
are not dragging. If they are, adjust and/or repair them so that they will work effectively when needed.
Note: When the machine is to be unhooked from the towing vehicle, set the Parking Brake and
proceed to unhook the machine in the same manner as it was hooked up, except in reverse order.
Note: The speed at which this machine is towed depends on conditions and the personal judgment of
the individual in charge but must not exceed 45 mph. Broce Manufacturing Co. will not be responsible
for neglect or poor judgment at any time during machine operation and/or towing of the machine.

OPERATION OF THE SWEEPING CORE
All functions of the sweeping core are hydraulically operated. Two control valve handles are mounted to
the right of the operator’s seat for controlling these functions. The Joystick controls the core height up
down and the right and left angle of Broom. The handle beside it controls the operation of the core
motor. Turf Boss and machines with variable brush speed have brush controls on the dash panel.
RAISE / LOWER / FLOAT DETENT
To raise the core, move the Joystick to the back, “RAISE,” position until the core is raised all the way. The
handle will return to the hold position and core height will be maintained. To lower the core during
normal sweeping conditions, move the Joystick to the front, “FLOAT” position. The “FLOAT” position will
allow the core to maintain the ideal contact while allowing it to float over bumps or contours in the
surface. This valve is equipped with a feature called “POSITIVE DOWN PRESSURE.” It should only be used
under the heaviest sweeping conditions. The down pressure adjustment is located between the hold
position and the float detent. To adjust the core height downward, slowly move the handle from the hold

6
position to the lower position. The core will begin to move downward. Release the handle when the
desired height has been achieved.
NOTE: The operator must maintain continuous adjustment on the core while the down pressure option
is being used. This feature does not allow the core to float over contours in the surface. Therefore, the
operator must constantly make these adjustments. If the broom core is forced to close to the ground, the
bristles will not have the “flicking” action which is necessary to do a proper sweeping job. This is why the
float is recommended during all but the heaviest sweeping conditions.
IMPORTANT: OVER USE OF THE POSITIVE DOWN PRESSURE FEATURE WILL CAUSE EXCESSIVE WEAR
AND SHORTEN THE LIFE OF THE BROOM.
RIGHT / LEFT ANGLE
The core may be set at any angle from 40oleft to 40oright. Move the Joystick to the right and it moves the
core towards the right rear wheel, likewise for the left. Release the handle when the desires angle is
achieved.
BROOM ON / BROOM OFF/BROOM SPEED
The core motor is activated with the handle to the right and is moved to the front, “ROTATION ON’
position and turned off when the handle is moved back, “ROTATION OFF” position. Turf Boss machines
have variable brush speed controlled by a dial on the dash panel.

SWEEPING TIPS
1. If the broom starts to hop or bounce, the propelling speed is too high. Slow the machine down, but
maintain high engine speed. This will allow you to do a good job on the first pass and you will not
need to go over it again.
2. In areas where the dirt is caked, try to clean the sweeping surface by going over it a second or third
time. If this does not clear the dirt, use the Positive Down Pressure feature, although in most cases,
the float position will yield the best results.
3. When changing the direction of travel, for example, backing up to sweep a spot which was not
cleared the first time, always allow the machine to come to a complete stop before moving the shift
lever in the opposite direction. This will help eliminate break downs and costly down time.
4. If the dust cloud becomes so thick that your vision is obscured, use the water sprinkling system or
stop the machine until the dust clears. If possible, angle the sweeper so that the dust and debris is
swept downwind.
5. Always wear eye protection, hearing protection and dust mask for respiratory irritants.
WARNING
OPERATOR MUST BE AWARE OF ANY PEOPLE OR PROPERTY WHICH MAY BE IN THE PATH OF FLYING
OBJECTS CAST BY THE ROTATING BRUSH. FLYING OBJECTS CAN CAUSE INJURY OR DEATH.

EXTENDING BRUSH LIFE
BRUSH DOWN PRESSURE
Most problems of rapid wear, bristle breakage and loss are attributed to excessive down pressure. If the
proper down pressure is used, the sweeping efficiency will improve and bristle life will be extended
considerably. More down pressure does not give a result of better sweeping. The broom gets its sweeping
action by the flicking action of the bristles.
Broce Brooms are equipped with a float detent control valve. This function should be used as often as
possible for optimum
sweeping and longer
brush life.
When too much down
pressure is used, the side
of the bristle is in contact
with the working surface
and very little flicking
action is present to give a
good clean sweep.
Set broom down
pressure to maintain
sweeping pattern as
shown, approximately 5-
6 inch width.
KEEPING BROOM LEVEL
Running the broom core out of level will result in a poor sweeping job and a shortened wafer life. Check
the broom core for levelness every day it is to be used.
There are three things to look for if the broom core is not level.
1. Make sure both of the rear tires are inflated to the same pressure. Both rear tires should be
the same brand and size to help in keeping the machine level.
2. Check the frame and make sure it is not bent.
3. Make sure the hanger bearing hub bolts are tightened evenly and the hub bearings are
adjusted properly.
PROPER GROUND SPEED
Rotary sweepers work best when they use a flicking action of the bristles. The broom can sweep debris to
a depth of ½ the diameter of the brush or to the point where the frame or a shield is in contact with the
debris and causes a restriction in the natural sweeping process. If the ground speed is too fast the debris
may build up in front of the brush causing a wind row effect. This wind row effect will put excessive side
pressure on the bristles and they will break off at the metal ring that holds them in place.
Always sweep at a brush rotation speed that is high enough and a ground speed that is low enough to
discharge the debris effectively and result in a clean sweeping job.
