OPERATIONAL SAFETY PRECAUTIONS
This symbol means: CAUTION ! Your safety is at rick !
– Reduce speed when turning, taking curves, rough ground, or hillsides to reduce
chance of rollover.
– Always keep tractor in gear when traveling downhill to prevent runaway.
– When driving on a road, day or night, use lighting and markings required by local
laws.
– Lower equipment when not in use.
– Whenever stopping or leaving the unit you should: stop tractor and equipment,
lower equipment, be sure all motion stops, and remove key.
– Become familiar with the controls. Familiarilty of controls and functions increases
efficiency and decreases hazardous situations.
– Never allow children to operate the sweeper or mower.
– Clear sweeping area of all foreign objects. Remove objects that coul cause
personal injury to the operator or others. Keep other sersons, children, and pets
ou of the work area.
– Always wear the proper apparel such as a long sleeve shirt buttoned to the cuffs
and safety glasses, goggles, or a face shield.
– Never operate the unit without all shields and hood in place.
– Plan your work ahead of time to help avoid accidents.
– Keep hands, feet, hair, and loose clothing away from engine, drive line,
brush, and other moving parts.
– If the unit is left unattended, even for a very short time, shut off engine, set parking
brake, and remove key.
_ Never sweep towards people, buildings, vehicles, or other objects that may be
damaged by flying debris.
– Dust and debris can be blown back into the operators face if consideration is not
given to wind direction. Wear the proper protective apparel.

OPERATION
Be sure the ball valves on the mower hydraulic tank are OPEN before starting the
tractor. Serious damage to the hydraulic system can occur if the valves are not OPEN.
For brush operation: open the high pressure valve located near the pressure port of
the pump and close the high pressure valve located near the electrical solenoid. This
procedure shuts off the oil flow to the mower.
For mower operation: close the high pressure valve located near the pressure port of
the pump and open the high pressure valve located near the electrical solenoid. This
procedure shuts off the oil flow to the brush.
Low brush speed and moderate ground speed will clean almost any hard surface of
all debris. Do not use high brush speeds or dust may be raised by the aggressive action
of the sweeper. Always remember the wind direction and plan your sweeping so it blows
at your back or to the direction that the brush head assembly is angled.
It is usually more effective to plan your sweeping for the days when it is overcast and
humid or on a day after it has rained. By planning in this manner, your dust will be kept
to a minimum.
To sweep gravel, use just enough brush spee to “roll” the gravel and not to throw it.
The sweeper is not a bulldozer!! Do not ram into piles trying to move them as a blade
would.
Remember, the sweeper sweeps with the tips of the broom, not wilth the sides like a
mop. Adjust the spring - chain assembly accordingly.
High brush speeds and low ground speeds are needed to do a good job in snow.
Start with about 3/4 throttle for wetter and deeper snow. This will help to keep the snow
from packing up inside the brush hood.
Just about any amount of snow can be thrown by the sweeper if enough patience
and consideration of the wind direction are used. In deep snow more than one pass may
have to be made to get down to a clean surface.
All Tiger Sweepers are equipped
with adjustable spring assemblies to
limit down pressure. Too often these
springs are removed and thrown away
or ignored. Proper down pressure
should be as pictured to the right.
Check and be sure you are using the
spring assembly. If it is lost or missing,
please order another from the dealer
or factory. If it is on, make sure you
understand and adjust it for poper
usage.

CORRECT SWEEPING PATTERN

PAGE-6
It is very possible to cut brush life by 50% if the
frame is not level. Running an unlevel brush is
jast like throwingmoney out the window. The
small amount of time spent leveling a brush
before sweeping is paed back many times over
in longer brush life.
As a general rule brush level should be checked
every day before operating.
Uneven brush wear can also be caused by
discharging material to the same side of the
brush all the time. Flipping the brush core end -
for - end a couple of times during the course of
the brush life can help alleviate this.
Improper ground speed not only damages the
brush bur also cores, chains, sprockerts, drive
lines and even frames.
A rotary sweeper sweeps with the flicking action
of the bristle. The brush can sweep material up
to 1/2 the diameter of the brush. If the ground
speed of the vehicle is too fast the material
piles in front of the brush because it cannot be
discharged. This plow effect is caused by bull -
dozing with the sweeper instead of sweeping,
this will causes a side thrust on the brush, core
and frame components.
This sideward thrust causes the bristles to flex
against the steel ring holding them. Eventually
this flexing will break the bristles off at the ring.
Always sweep at a high enough brush speed
and low enough ground speed to effectively
discharge the material being swept.

1. Do not store sweeper polypropylene brushes in direct sunlight!
Direct sunlight will cause the bristles to deteriorate, causing the bristles to become
brittle. If the broom is to be stored for any length of time, store it in the shade,
inside, or cover the brush with a tarp to protect it from the sun.
2. Do not stor the sweeper power broom with the weight on the bristles!
Storing the sweeper power broom with the weight on the bristles will permanently
deform the bristles, destroying the sweeping effectiveness of the brush. Block the
brush up off the ground.
WITH PROPER CARE, YOUR POLYPROPYLENE BRUSH WILL GIVE LONG HOURS
OF TROUBLE FREE SERVICE, WITH EXCEPTIONALLY LOW WEAR ON BRUSH.
3. How do you get longer brush life?
Three factors can be controlled to give longer brush life. Brush down pressure,
brush level (uneven brush wear), ground speed.
BRUSH DOWN PRESSURE: more down pressure does not give a better sweep.
A brush gets its sweeping action by the flicking action of the bristles. This is most
effectively done with the tips of the bristles.
When too much down pressure
is used the brush is working with
the sides of the bristles, not just
the tips. This mopping action not
only decreases the efficiency of
the brush but also causes 1/2” to
1 1/2” of bristle to be worn off at
once. Improper down pressure,
depending on the amount, can
decrease brush life 5% to 95%.

MOUNTING INSTRUCTIONS
Please rea and understand the instructions and schematics completely before
beginning assembly.
Parts and drawings may vary slightly due to the variety of tractor makes and models.
The mounting kit you receive should be correct for your application. If questions arise
please contact your local dealer or Tiger Service as needed.
Lay out all loose parts on a clean surface for easy identification. Part numbers and
descriptions can be found in this manual and other information received with ypur par-
ticular unit. Any shortages should be reported immediately.
The following assembly instructions are based on the assumption a Tiger mower is
already mounted on the tractor. Variations may occur in parts and assembly onto other
makes and models.
1. Mount the control valve stand within easy access of the operator (usually
mounted to the existing mower control valve stand).
2. Mount the two - spool control valve onto the control valve stand. Install the 1/2”
pressure and return hoses as shown on the schematic. This will maintain oil
containment until assembly is complete. Note: (If your tractor has a closed center
hydraulic system, it will be necessary to a closed center plug in the control valve).
Use teflon tape on all N.P.T. fitting and joints.
3. Mount the sweeper mounting frame onto the front of the tractor. Secure the frame
using lockwashers and capscrews provided. Be sure to use loctite on mount
bolts.
4. Position the swing assembly in front of the mounting frame as shown in the parts
breakdown section of this manual.
5. Turn the leveling bolts “A” and “B” all the way in, see figure A.
6. Remove the two 7/8” x 3” pins from the swing assembly mounting ears. Raise the
swing assembly and align the holes in the swing assembly mounting ears with the
holes inthe tractor frame mounting ears.
7. Insert 7/8” x 3” pins and secure with cotter pins.
8. Position the brush head asembly in front of the swing assembly as shown in the
parts breakdown section.
9. Remove the nuts and washers from the mounting bolts in the front plate of the
swing assembly.
10. Raise the back of the brush head frame and align the center bolt holes. Insert
the center hex head bolt and secure with the lockwasher and nut. Align the
slotted hole on each side of the center bolt, insert carriage bolts and secure with
flatwasher, lockwasher, and nut. These three brush head mounting bolts must
be left loose enough to allow for leveling.

PAGE-9
11. The spring - chain assemblies are used to help support the weight of the brush
head assembly when in the sweeping position. Hook on spring to each of the
outside holes in the top plate of the brushhead upright. The chains are con
nected to the outside slots in the chain holder on the spring - chain assembly.
The spring - chain assemblies will require adjustment after installation is
complete.
12. Connect a 1/4” hydraulic hose from the lift cylinder to the left front port of the
control valve on the control valve stand. Note: (quick coupler end to valve).
13. Connect the 1/4” hydraulic hoses from the swing cylinder to the control valve.
The hoe connected to the swing cylinder at the rod end is connected to the right
front port of the control valve. The hose connected to the anchored end of the
swing cylinder is connected to the right rear port of the control valve. Note:
(quick coupler end to valve).
14. Connect the two 1” Hydraulic hoses to the tees on the brush head. Short hose
routes from pressure side of pump to top tee. Long hose routes from the bottom
tee to return side of solenoid valve. See brush feedline assembly schematic.
15. To connect the lift chain for the brush head, push the lift control forward and at
the same time pull out the lift bracket which is pinned to the lift cylinder of the
swing assembly. Drop the lift chain into the slot in the lift bracket. It may be
necessary to try two or three different chain links to fing the one that gives the
best and smoothest lift. Do not make the lift chain so short that the brush head
upright hits the lift bracket on the swing assembly when the brush head is raised.
16. You are now ready to level the brush head.

PAGE-10
LEVELING INSTRUCTIONS
The sweeper must be leveled t maintain even brush wear and to produce efficient
sweeping action. If the broom is not leveled at first and periodically after that, then it will
put stress on certain parts causing excessive wear. The broom is easily leveled if these
steps are followed.
1. Drive the assembled broom onto a level paved area. Swing the brush head
assembly to the straight position. Lower the brush into the sweeping position with
the weitght of the brush head assembly resting on the ground.
NOTE: all adjustments for leveling are made with bolts “A”, “B”, “C” and “D”.
See illustrations below:
2. Adjust bolts “A” and “B” so both are turned out an equal distance and support an
equal amount of weight. From this point on, bolt “A” and “B” must both be turned
in or out equal amounts to equalize the weight of the head.
3. Adjust bolt “A” and “B” in or out equally as required to level the swing assembly
from front to rear.
4. Raise the brush head assembly about two inches off the ground and angle it fully
to the right. Measure the distance fromthe ground up to the brush head frame at
both ends. See illustration below:
Adjust bolt “C” in Adjust bolt “D” in Adjust bolts “A” & “B” in Adjust bolts “A” & “B” out

PAGE-11
Make a note of the measurements. Swing the brush head assembly to the left and
take the same measurements. If the measurements are not equal, refer to previous
leveling steps and illustrations for adjustments.
LEVELING INSTRUCTIONS CONTINUED
5. After leveling, tighten the brush head mounting bolts E, F and G

PAGE-12
SUPPORT YOKE ADJUSTMENT
NOTE: This section applies only to units with serial number 75146 and above. Units
with serial number below 75146 do not have adjustable support yokes. Before operating
the sweeper the brush head frame support yokes should be checked and if necessary
adjusted as follows:
1. Loosen the two 5/8” carriage bolts in each of the support yokes as shown in the
figure below.
2. Swing the brush head assembly fully to the right.
3. Snug the right support yoke around the brush head tube and tighten the two 5/8”
bolts.
4. Swing the brush head assembly fully to the left.
5. Snug the left support yoke around the brush head tube and tighten the two 5/8”
bolts.
6. Check the brush head assembly for proper leveling. It may be necessary to adjust
the support yoke up or down in order to achieve correct leveling of the brush
head assembly.
