SPECIAL TOW VEHICLE INSTRUCTIONS
Special Instructions for Workman
(3000/4000) and other utility tow vehicles
(tractors):
1. The TopDresser 2500 can be towed by most utility
tractors equipped with flotation tires for operation over
golf greens. The tractor must have adequate brakes
and drawbar hitch capacity to handle a 3500 lbs. (1587
kg.) trailer. Refer to Tractor Operator's Manual for
towing instruction and precautions.
2. The Workman(3000/4000) vehicle, equipped with
the Heavy Duty Drawbar (Model 44212 or 44213)
makes a good tow vehicle (4WD version is best for hilly
or bermed approaches to greens).
NOTE: For improved traction and when towing
TopDresser 2500, 1000 lbs. of weight can be added to
vehicle bed.
IMPORTANT: Do Not attempt pulling the Topdresser
2500 when loaded with material, with the standard
Workman (3000/4000) hitch. It is only rated to 1500 lbs.
and may bend or damage the cross tube axle support or
rear spring shackles. Always use the H.D. Drawbar Kit
Model 44212 or H.D. Frame Drawbar Model 44213.
IMPORTANT: Do Not attempt towing a loaded
topdresser with a light utility vehicle or run-about. They
do not normally have adequate brakes, suspension, or
frame strength to handle the weight of the
TopDresser2500.
3. Trailer Brakes are highly recommended when
using the Top Dresser 2500 in hilly terrain. When fully
loaded the topdresser may weigh as much as 3500
lbs.(GVW). This weight is well over the recommended
towing and braking limit of most utility vehicles. A
special trailer brake kit is available for direct installation
with the Workman (3000/4000) vehicle. This kit could be
adapted to other vehicles with a 12 volt brake light
source.

BEFORE OPERATING
CHECK HYDRAULIC SYSTEM FLUID
The machine's reservoir is filled at the factory with
approximately 2.5 gallons (9.5 l) of high quality
hydraulic fluid. Check the level of hydraulic fluid
before the machine is first operated and daily
thereafter. Appropriate hydraulic oils are listed below.
The following list is not assumed to be all-inclusive.
Hydraulic fluids produced by other manufacturers may
be used if they can cross reference to find an equivalent
to the products listed. Toro will not assume
responsibility for damage caused by improper
substitutions, so use only products from reputable
manufacturers who will stand behind their
recommendation.
Manufacturer ISO VG 46 Multigrade
Mobil DTE 15M
Amoco Rykon Premium ISO 46
Chevron Rykon Premium ISO Oil 46
Conoco Hydroclear AW MV46
Exxon Univis N46
Pennzoil AWX MV46
Shell Tellus T 46
Texaco Rando HDZ 46
IMPORTANT: The ISO VG 46 Multigrade fluid has been
found to offer optimal performance in a wide range of
temperature conditions. For those who prefer them,
Universal Tractor Fluids such as Mobilfluid 424 (or
equivalent) offer acceptable performance with possibly
some loss of efficiency at high ambient temperatures.
Note: Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic system oil is available in 2/3 oz (20 ml)
bottles. One bottle is sufficient for 4-6 gal (15-232 l) of
hydraulic oil. Order part no. 44-2500 from your
authorized Toro distributor. Not recommended for
biodegradable fluid (use food coloring).
Biodegradable Hydraulic Fluid - Mobil 224H
IMPORTANT: Mobil EAL 224H is the only
biodegradable oil tested and approved by Toro.
Contamination by mineral-based hydraulic fluids may
change the biodegradability and toxicity of this oil.
When changing from standard fluid to the
biodegradable type, be certain to follow the approved
flushing procedure published by Mobil. Contact your
local Toro Distributor for details. This oil is available in 5
gallon (19 l) containers from your Toro Distributor, order
part no. 100-7674.
NOTE: Mobil EAL224H and most other hydraulic oils
are almost colorless, making it difficult detect leaks. A
non-toxic dye additive, such as food coloring, can be
added to improve visibility. Do not use hydraulic oil dyes
as they may be toxic.
Mobil EAL 224H is available, in 5 gallon containers (Part
No. 100-7674) from your local Toro Distributor. If you
wish to use an alternate biodegradable and nontoxic
hydraulic fluid, first the hydraulic tank, filter, all lines,
hoses, motors and pumps must be completely drained
to insure that the new oil will fully circulate and coat all
components in the hydraulic system, and reduce the
chance of gelling or stratifying in certain portions of the
circuit. Make sure to replace filter.
NOTE: Be certain that you select an equivalent ISO
Viscosity Grade 32/46 hydraulic fluid.
Mixing of hydraulic fluids-Regular petroleum hydraulic
fluids, such as Mobil DTE 15 M (Refer to Table) can be
added to the system without affecting the performance
or life of the components. These mineral based
hydraulic fluids and their normal wear additives, even in
small quantities, destroys the biodegradability and
non-toxicity of the fluid, and the entire system must be
considered environmentally hazardous.
1. Position machine on a level surface.
2. Clean area around filler neck and cap of hydraulic
tank. Remove cap from filler neck.
Figure 6
1. Hydraulic Tank Cap
1
3. Check fluid level. Fluid level should be 1/2 way up
screen in filler neck.
4. If level is low, add appropriate fluid to raise level.
Disposal And Spillage
Depending on contamination and/or degradation
levels, small amounts of spilled or leaked Mobil
EAL224H will not adversely affect ground water or the
environment. For small spills on the ground the
uncontaminated product will be readily biodegraded by
naturally occurring soil organisms when exposed to air.
Nonetheless, spillage of Mobil EAL 224H should be
handled similarly to currently accepted methods for
conventional mineral oil spills.

12
BEFORE OPERATING
Mobil EAL224H does not contain hazardous
substances reportable under CERCLA. Since all oil
spills are reportable, even a spill of this vegetable
oil-based product must be reported to the National
Response Center (the U.S. Coast Guard). Local
environmental agencies should also be consulted to
clarify local requirements.
Acceptable methods of disposal include use as a fuel
supplement, recycling and reclamation (that is, the
same disposal practices available for conventional
mineral oils). Since Mobil EAL 224H typically will not be
hazardous waste, additional disposal options may be
available, including land farming or processing through
sewage treatment facilities, if necessary approvals are
obtained from appropriate authorities.
The flushing solution may not be biodegradable,
therefore, it should be disposed of in an
environmentally safe manner. Follow procedures used
for disposing of conventional mineral oils.
Health And Safety
Based on available toxicological information, Mobil
EAL224H produces no significant adverse effects on
health when properly handles and used. No special
precautions are suggested beyond attention to good
personal hygiene, including laundering oil soaked
clothing and washing skin contact areas with soap and
water. For additional technical information or to order a
Material Safety Data Bulletin, call 1-800-662-4525 or
www.mobil.com.
CHECK TIRE PRESSURE
The tires are over-inflated for shipping. Therefore,
release some of the air to reduce the pressure. Correct
air pressure is 20-30 psi.
IMPORTANT: Maintain even pressure in all tires to
assure even weight distribution on turf and proper
machine performance. DO NOT UNDER INFLATE.
CHECK WHEEL BOLT TORQUE
WARNING
Torque wheel bolts to 8090 ft-lb after 14
hours of operation and again after 10 hours of
operation and every 200 hours thereafter. Fail
ure to maintain proper torque could result in
failure or loss of wheel.

OPERATING INSTRUCTIONS
GENERAL
1. The Top Dresser 2500 is ground driven, so it will
need to be towed in order to check out operation of belt
and brush. Factory checks are performed on a powered
roller drum.
2. Top dressing works best at 2 to 8 miles per hour
(mph). The TopDresser 2500 compensates for
variations in travel speed, and will give consistent
distribution, even if travel speed changes during a pass
across the green. The operator/superintendent should
make a gate setting selection (variable in 1/8
increments to 13) and make a first pass to determine if
application rate is acceptable. (see Sand Application
Rate, page 16)
3. Operation begins when the hand control switch is
activated. This may require some practice to start and
stop the flow of material at the desired collar area of the
green or tee box.
4. Before loading hopper, make sure topdresser is
properly connected to tow vehicle, to prevent flip-up or
any unintended tongue movement. Do Not unhook
topdresser from tow vehicle with material in hopper.
Tongue may flip up causing injury.
5. When traveling through narrow areas such as
gates, door entries, etc. be aware that topdresser is
wider than the tow vehicle. Always check width before
proceeding and allow room for clearance to turn.
6. The top dresser adds extra towing weight to the
vehicle. Drive the vehicle safely.
A. Do not drive on highway or public roads.
B. Always SLOW the tow vehicle when
approaching and while making a turn.
C. Always SLOW the tow vehicle when driving in
unfamiliar areas or over rough terrain.
D. Always SLOW the tow vehicle when changing
direction of travel or preparing to stop.
E. When turning or driving on slopes, always
SLOW the tow vehicle, then turn to prevent loss of
control and possible upset.
F. DO NOT make sudden or sharp turns. DO NOT
suddenly change direction of travel on an incline,
ramp, grade, slope or similar surface.
G. Always adjust the tow vehicle speed to allow for
existing ground conditions such as wet slick
surfaces, loose sand or gravel and/or low visibility
conditions such as dim or bright lighting, fog, mist
or rain.
H. Be especially careful when driving a heavily
loaded vehicle down an incline or slope. Drive the
vehicle UP and DOWN the face of the slopes,
inclines or grades whenever possible. DO NOT
DRIVE across the face if at all possible. There is a
risk of upsetting the vehicle, which can result in
serious injury or death.
WARNING
Tipping or rolling the tow vehicle on a hill will
cause serious injury.
If engine stalls or you lose headway on a hill,
never attempt to turn tow vehicle around.
Always back straight down a hill in reverse
gear.
NEVER back down in neutral or with the clutch
depressed, using only the brakes.
NEVER add sideboards or panels to the top of
the hopper to increase the load capacity. The
additional weight will cause tipping or rolling of
the tow vehicle and lead to serious injury.
NEVER drive across a steep hill, always drive
straight up or down. Avoid turning on a hill.
Don't "drop the clutch" or slam on the brakes.
Sudden speed change can initiate tipover.
7. In tight areas, where a straight line pass across a
green is not possible, the TopDresser2500 can be
backed onto the area without harm and begin
topdressing when pulling forward. See the hydraulics
section for more information on the special features of
the Top Dresser 2500.
8. Before backing up, look to the rear and assure no
one is behind. Back up slowly and watch the top
dresser movement closely.
9. Use extreme caution and slow speed when backing
up the top dresser and tow vehicle.
10. The maximum recommended towing speed is 15
mph (Loaded 8 mph). As with any trailer, always use
caution when turning or backing up. Be aware of
persons or objects near the topdresser path of travel.
11. Watch out for traffic when near or crossing roads.
Always yield the right of way to pedestrians and other
vehicles.
12. If the top dresser begins to vibrate abnormally, stop
immediately. Shut off the tow vehicle engine. Repair all
damage before commencing towing.
13. If cavitation noise is heard while transporting across
the golf course, slow down, return to maintenance, and
investigate the cause. Do not exceed the 15 mph tow
speed. This unit was not designed for travel on
highways. Damage will occur to the internal hydraulic
components.

OPERATING INSTRUCTIONS
14. Before servicing or making any adjustments to the
top dresser:
A. Stop the tow vehicle and set the parking brake.
B. Shut off the tow vehicle's engine and remove
key from ignition.
15. Keep all nuts, bolts and other fasteners tightened
securely. Replace any parts removed during servicing
or adjustments.
16. When loading the top dresser mix into the hopper,
be careful that the loader or skid steer bucket does not
strike and buckle the hopper sides. Although designed
to be wide enough to clear most buckets, it is not strong
enough to take a direct hit and may deform the sheet
metal.
17. Dispersion is always best with dry material, but wet
sand can be spread with the special traction grip belt on
the Top Dresser 2500. Some adjustment to the gate
setting may be required, but the material should flow
out and spread relatively smooth and consistent. If any
slippage of the belt appears to be occurring, check the
Maintenance section; Belt adjustment and clean-out
provisions.
18. Topdress mix can vary in grain size as well as
moisture. It can also contain impurities that may either
damage greensmowers or plant tissue. Always control
the source of topdress material, and use care when
handling and loading.
19. A sight window is provided on the right front hopper
panel to monitor remaining material while topdressing.
It is good practice to glance over your right shoulder
and check the hopper volume before beginning
application to assure that you don't run out in the middle
of a pass.
20. The special oscillating drive axles on the Top
Dresser 2500 were designed to continue powering the
hydraulics while traversing over undulations and
irregularities in the surface of the green or tee. Always
approach severe berms slowly to avoid sudden impact
of the axles with the turf, and to reduce the potential of
leaving tire marks on the approach to the green.
WARNING
Rotating parts can grab or pinch. Stay clear of
brush and conveyor belt while unit is running.
Safe operation begins before taking the top dresser out
for a day's work. Read and understand the operating
instructions in the Toro Workman or other tow vehicle
operator's manual before using the topdresser.
CAUTION
The interlock switches are for the operator's
protection, so do not bypass them. Check op
eration of the switches daily to assure interlock
system is operating on the Workman. If a
switch is malfunctioning replace it before oper
ating. Regardless whether switches are oper
ating properly or not, replace them every two
years to assure maximum safety. Do not rely
entirely on safety switches - use common
sense!
OPERATION
1. Sit on operator's seat and engage tow vehicle
parking brake.
2. Disengage PTO (if so equipped) and return hand
throttle lever to OFF position (if so equipped).
3. Move shift lever to NEUTRAL position and depress
clutch lever.
4. Insert key into ignition switch and rotate it clockwise
to start the engine. Release key when engine starts.
5. Practice starting, driving and stopping the tow
vehicle. Always read and understand the operator's
manual for the tow vehicle before using this unit.
6. Check for smooth operation of belt before adding
material in hopper.
7. Place sand or other topdressing material in the
hopper. The maximum volume of material that can be
put into the hopper is 25 cubic feet. Generally, sand
weighs 100 pounds per cubic foot and could overload
the unit if more than 2050 pounds are loaded into the
hopper.
IMPORTANT: Overloading can result in side wall
deflection of tires and marking of green on first few
passes. Check tire pressures - Recommended
pressure is 20 - 30 p.s.i. max.
8. Transport to the area to be topdressed.
9. Adjust the metering gate to the desired rate. Lock
into position with the black knob.
10. For best results, move the shift lever into "LO" range
position. Select the desired forward speed and begin
moving. Refer to the following section, Sand
Application Rate.

16
OPERATING INSTRUCTIONS
DANGER
As a general rule, position the weight of the
load evenly from front to rear and evenly from
side to side.
Transporting or topdressing with a full load can
cause shifting of the sand. This shifting hap
pens most often while turning, going up or
down hills, suddenly changing speeds or while
driving over rough surfaces. Shifting loads can
lead to tipovers. Use caution when transport
ing or topdressing with a full load.
Heavy loads increase stopping distance and
reduce your ability to turn quickly without tip
ping over.
SAND APPLICATION RATE
The rate of sand applied depends on the gate setting.
Sand varies in moisture and coarseness (size of grain)
which effects the rate. These factors must be taken into
consideration when deciding the amount of sand
required for the application. Test a small area to decide
the correct amount. To increase application rate open
gate to a higher scale mark.
The TopDresser 2500 is ground driven which assures
consistent application, from green to green, when
towing speed is within the recommended 2-8 mph..
SAND PRECAUTIONS
The Topdresser 2500 is equipped with a flexible gate
edge (Fig. 8) and spring release mechanism to reduce
the chance of sand chunks or rocks getting lodged
during operation. To insure long belt life, sift or check
sand for rocks with sharp edges that may damage
conveyor belt.
Figure 8

COLD WEATHER OPERATION
Although limited by traction of drive tires, the
Topdresser 2500 may be used in cold weather, with
certain limitations, to apply a salt/sand mixture on
pavement for ice control. The PVC conveyor belt
material becomes very stiff in cold weather and requires
more power to operate belt. The life of the belt is
reduced by approximately 50% when operated below
temperatures of 40F (5C). Under no conditions
should the topdresser be operated below
temperatures of 20F (-7C).
1. Increase belt tension by adjusting spring
compression to 4 inches (101 mm). Refer to Adjusting
Conveyor Belt, page 20.
2. Always run belt, before adding material, to
assure moisture has not frozen belt system.
Damage to belt or roller may occur if belt/drive roller
slip.
IMPORTANT: Always re-set belt tension to normal
4-7/16" (112 mm) spring compression adjustment
before operating topdresser under normal
temperature conditions.

17
LUBRICATION
GREASING BEARINGS
The Topdresser 2500 has 13 grease fittings that must be
lubricated with a No. 2 Lithium based grease. Lubricate
annually or after every 200 hours of operation.
The grease fitting locations and quantities are: Roller
shaft bearings (4) (Fig. 9), Brush shaft bearing (1)
(Fig. 9), Pivot bearings (4) (Fig. 10) and Wheel bearings
(4) (Fig. 10).
IMPORTANT: Lubricate the bearings to maintain a
slight leakage between bearings and housings. Too
much grease can cause overheating aor damage to
seals.
NOTE: We do not recommend lubricating the drive
chains unless they become stiff because of rust. If the
chain rusts, it may be lubricated lightly with a
DRY-TYPE LUBRICANT. This will reduce the chance
for build-up of sand or other topdress material on
chain.

CHANGING HYDRAULIC FLUID
Change hydraulic fluid after annually or every 200
operating hours, in normal conditions. If fluid becomes
contaminated, contact your local TORO distributor
because the complete system must be drained.
Contaminated fluid looks milky or black when
compared to clean oil.
1. Position machine on a level surface.
2. Remove fitting from bottom of reservoir and let
hydraulic fluid flow into drain pan. Reinstall and tighten
fitting when hydraulic fluid stops draining.

3. Fill reservoir with approximately 2.5 gallons (9.5 l) of
hydraulic fluid. Refer to Checking Hydraulic Fluid.
IMPORTANT: Use only hydraulic fluids specified.
Other fluids could cause system damage.
4. Check level of fluid and add enough to raise to
proper level. DO NOT OVER FILL. Refer to Checking
Hydraulic Fluid.
5. Install reservoir cap.
REPLACING HYDRAULIC FILTER
Change hydraulic filter annually or after every 200
operating hours, in normal conditions.
Use the Toro replacement filter (Part No. 86-3010.
IMPORTANT: Use of any other filter may void the
warranty on some components.
1. Position machine on a level surface.
2. Clean area around filter mounting area. Place drain
pan under filter and remove filter.

MAINTENANCE
WARNING
Keep body and hands away from pin hole leaks
or nozzles that eject high pressure hydraulic
fluid. Use cardboard or paper to find hydraulic
leaks. Hydraulic fluid escaping under pressure
can penetrate skin and cause injury. Fluid acci
dentally injected into the skin must be surgical
ly removed within a few hours by a doctor famil
iar with this form of injury or gangrene may re
sult.
BRUSH ADJUSTMENT
Brush must make enough contact with conveyor belt to
disperse topdressing material but not restrict the
rotation of the brush. A piece of stiff paper can be
inserted between the conveyor belt and the brush to
check the adjustment. The brush must be the same
height from side to side. The brush adjustment should
be checked weekly for wear. The bristles of the brush
will wear under normal conditions and the distance
from the brush to conveyor belt should be maintained to
prevent uneven wear of the brush.
NOTE: If using moist top dressing materials, brush may
have to be adjusted so bristles will whisk material from
between conveyor belt lugs without severely contacting
smooth portion of belt.
1. Loosen nuts securing bearing housing (Fig. 14) to
right side of machine.
