signal words used to identify the level of hazard.
However, regardless of the hazard, be extremely careful.
Danger signals an extreme hazard that will cause serious
injury or death if you do not follow the recommended
precautions.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or
moderate injury if you do not follow the recommended
precautions.
This manual uses two other words to highlight
information. Important calls attention to special
mechanical information and Note: emphasizes general
information worthy of special attention.
• Keep in mind that the operator or user is responsible
for accidents or hazards occurring to other people or
their property.
• The owner/user can prevent and is responsible for
accidents or injuries occurring to himself or herself,
other people, or property.
Preparation
• While mowing, always wear substantial footwear, long
trousers, hard hat, safety glasses, and ear protection.
Long hair, loose clothing, or jewelry may get tangled
in moving parts. Do not operate the equipment when
barefoot or wearing open sandals.

– Refuel outdoors only and do not smoke while
refuelling.
– Add fuel before starting the engine. Never remove
the cap of the fuel tank or add fuel while the
engine is running or when the engine is hot.
– If fuel is spilled, do not attempt to start the engine
but move the machine away from the area of
spillage and avoid creating any source of ignition
until fuel vapors have dissipated.
– Replace all fuel tanks and container caps securely.
• Watch out for traffic when crossing or near roadways.
• Stop the blades rotating before crossing surfaces other
than grass.
• When using any attachments, never direct discharge of
material toward bystanders nor allow anyone near the
machine while in operation.
• Never operate the machine with damaged guards,
shields, or without safety protective devices in place.
Be sure all interlocks are attached, adjusted properly,
and functioning properly.
• Replace faulty silencers.
• Evaluate the terrain to determine what accessories and
attachments are needed to properly and safely perform
the job. Only use accessories and attachments
approved by the manufacturer.
• Check that operator ’s presence controls, safety
switches and shields are attached and functioning
properly. Do not operate unless they are functioning
properly.
Operation
• Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect.
• Mow only in daylight or in good artificial light.
• Before attempting to start the engine, disengage all
blade attachment clutches, shift into neutral, and
engage the parking brake.
• Do not use on slopes of more than
–5° when mowing on side hills;
–10° when mowing uphill;
–15° when mowing downhill.
• Remember there is no such thing as a safe slope.
Travel on grass slopes requires particular care. To
guard against overturning:
– do not stop or start suddenly when going up or
downhill;
– engage clutch slowly, always keep machine in gear,
especially when travelling downhill;
– machine speeds should be kept low on slopes and
during tight turns;
– stay alert for humps and hollows and other hidden
hazards;
– never mow across the face of the slope, unless the
mower is designed for this purpose.
• Stay alert for holes in the terrain and other hidden
hazards.
• Do not change the engine governor settings or
overspeed the engine. Operating the engine at
excessive speed may increase the hazard of personal
injury.
• Before leaving the operator’s position:

Before Operating
Fill Fuel Tank
Refer to Engine Operator’s Manual for fuel requirements.
Add Engine Oil
Crankcase must be filled with the proper viscosity, grade
and quantity of oil before staring.
Refer to Engine Operator’s Manual for oil requirements.
1. Position mower so the engine is level and clean around
oil level gauge (Fig. 5).
1
Figure 5
1. Oil level gauge
2. Remove gauge by rotating counterclockwise.
3. Wipe gauge clean and insert it into filler port. Then
remove and check level of oil. Do not screw into port.
If level is low, add only enough oil to raise level to
filler opening.
Note: The TORO Company recommends that the oil level
be checked each time mower is used or after every 5
operating hours. Initially, change oil after the first 25
hours of operation; thereafter, change oil after every 50
hours of operation. More frequent oil changes are required
in dusty or dirty conditions.
1. Clean around fuel tank cap and remove cap from tank
(Fig. 6). Fill fuel tank no higher than to bottom of
filter screen. DO NOT OVER FILL.
1
Figure 6
1. Fuel tank cap
2. Install fuel tank cap and wipe up any spilled gasoline.
Danger
Because gasoline is flammable, caution must
be used when storing or handling it. Do not
fill fuel tank while engine is running, hot or
when machine is in an enclosed area. Vapors
may build up and be ignited by a spark or
flame source many feet away. DO NO SMOKE
while filling the fuel tank to prevent the
possibility of an explosion. Always fill fuel
tank outside and wipe up any spilled
gasoline before starting engine. Use a funnel
or spout to prevent spilling gasoline, and fill
tank no higher than to bottom of filter
screen. DO NOT OVER FILL. Store gasoline
in a clean safety approved container and
keep the cap on the container. Keep gasoline
in a cool, well-ventilated place; never in an
enclosed area such as a hot storage shed. To
assure volatility, do not buy more than a 30
day supply of gasoline. Gasoline is a fuel for
internal combustion engines; therefore do
not use it for any other purpose. Since many
children like the smell of gas, keep it out of
their reach because the fumes are explosive
and dangerous to inhale.

Check Transaxle Oil Level
Adjusting Height-of-cut
Check transaxle oil level before initial startup and after
every 50 hours of operation.
1. Place mower on level surface and remove pipe plug at
rear of gear case. Oil should be to bottom of hole
(Fig. 7).
1
Figure 7
1. Pipe plug
2. If level is correct, replace plug. If level is too low,
remove plug in top cover and add SAE 90 gear oil
(Fig. 8). Replace both plugs.
Effective cutting height is dependent upon the condition
of the turf grass and the selection of various combinations
of skids or rollers available for the Greensmaster 500.
Effective height-of-cut on a green is influenced by the
type of grass, frequency of mowing, amount of thatch and
resilience of the soil — which is affected by the moisture
and organic matter content. The Greensmaster 500
provides an opportunity to select rollers, skids or
bedknives suitable for all types of greens turf grasses. For
example, progressively lower heights-of-cut with the same
gauge setting may be obtained by selecting, in the
following order: the skid, full front roller, sectional roller
or the Wiehle roller. The reason for this is that
progressively less supporting or contact area is provided
for the cutting unit. The micro-cut bedknife provides a
height-of-cut to 1/16, if desired.
1. Loosen nut on gauge bar and set adjusting screw to
obtain desired distance between bottom of screw head
and face of bar (Fig. 9). Tighten nut, making sure
adjustment is not altered.

2. Remove the cutting unit; refer to removal and
Installation of Cutting Unit.
3. Place cutting unit upside down on bench, position
gauge bar on end of unit with one end on front
support: skid, full roller, sectional roller, etc., the other
end on rear roller (Fig. 10).
4. Loosen top nut on adjusting screws on each side plate
(Fig. 10) and turn adjusting nut to raise or lower front
roller or skid assembly (Fig. 10). Adjust to make
contact with outer end of gauge bar. When proper
adjustment is obtained, screw head on gauge bar will
just pass over cutting edge of bedknife (Fig. 10).
ASSURE HEIGHT-OF-CUT IS EXACTLY
IDENTICAL AT BOTH ENDS OF BEDKNIFE.

3. Place the newspaper at right angles to the top face of
the bedknife against the front cutting edge and rotate
the reel blades against the paper. The reel blades
should cut the paper cleanly all across the bedknife. If
the paper is not cleanly cut, the mower should be
either backlapped or resharpened: refer to Backlap
Operation and Reel and Bedknife Grinding.
4. Place a strip of newspaper flat on the top face of the
bedknife and adjust reel down until reel blades pinch
the paper equally all across the bedknife.
5. Tighten nuts to secure the adjustment.

Adjust Rear Roller Scraper
The adjustment of the rear roller scraper depends on the
many conditions of the green (i.e. leaves, seeds, dew,
etc.).
1. Adjust scraper rod locknuts and brackets to attain
.06”–.10” clearance between scraper rod and roller
surface. Distance between bottom of rod and level
surface should be the same height as height-of-cut
setting.
2. Slide sleeves back on each ball joint and rotate each
pull arm upward off the ball studs.
3. Align cutting unit with roller and driveshaft with
transaxle shaft and lengthen or shorten pull rods by
threading ball socket on rod (Fig. 15).
4. Align ball sockets with ball studs so hooded portion of
socket is at top and open side toward stud (Fig. 16).

Check Cutting Unit Alignment
The cutting unit must be in alignment with the front yoke
roller so that the machine will track in a straight line
across the greens. The driveshaft must also be aligned
with the transaxle output shaft. If unit is not properly
aligned, use the following alignment procedures.
1. Loosen jam nut securing ball sockets to pull arms on
both side of the yoke (Fig. 15).
5. Slide the sleeve back on the ball joint and rotate the
pull arm down so the socket fits over the ball stud.
Release the sleeve so it slids forward over the stud and
locks the assemblies together. Tighten the jam nuts to
secure the sockets in position (Fig. 16).

Starting And Stopping
Note: Make sure wire is installed on spark plug.
1. Assure traction clutch control bail (Fig. 19) and reel
drive knob (Fig. 22) are in DISENGAGED position.
2. Open fuel valve at right side of engine (Fig. 20).
3. Turn ON/OFF switch to ON (Fig. 21)
4. Move choke lever (Fig. 20) to CHOKE position before
starting a cold engine, only if necessary.
Note: A warm or hot engine does not require any choking.
To start a warm engine, move throttle control to mid
throttle position.
5. Stand behind the machine, move the throttle control
lever to mid throttle position (Fig. 19). Pull recoil
starter handle out until positive engagement results.
Pull handle to start engine and allow rope to recoil
slowly. Open choke as engine warms up, if used.
Important Do not pull recoil rope to its limit or let go
of starter handle when rope is pulled out because rope
may break or recoil assembly may be damaged.
6. To stop engine during operation, release clutch bail to
DISENGAGE position (Fig. 21), throttle control to
SLOW (Fig. 19) and turn ON/OFF switch to OFF
(Fig. 21).
4. Adjust throttle to operate mower at desired ground
speed and transport mower to desired destination.
Prior To Mowing
Remove all foreign objects from the turf prior to mowing.
Be sure the Greensmaster is carefully adjusted and is set
evenly on both sides of the reel. Improper mower
adjustment is magnified many times over in the
appearance of the clipped turf. Ensure everyone,
especially children and pets, is clear of the work area.
Method Of Mowing
The greens should be mowed in straight back and forth
direction across the green. Avoid circular mowing or
turning the mower on greens areas since scuffing may
occur. Turning the mower should be done off the green
proper by raising the cutting reel (pushing the handle
down) and turning on the large rubber covered traction
drums. Mowing should be done at a normal walking pace.
Faster speed saves very little time and will result in an
inferior mowing job.
Operating Controls
To operate controls for mowing;
1. Start engine, push down on handle to elevate cutting
unit, raise traction clutch bail to handle and transport
machine onto collar of green.
2. Release traction clutch bail (Fig. 23) to DISENGAGE
position and pull reel drive control knob on transaxle
fully out to ENGAGE reel (Fig. 24).

wrench by the following method:
• Install a 1/4-20 screw into hole in end of reel shaft
(Fig. 37).
• Support the reel and hang a 5 lb. (2.27 Kg) weight 1
in. (25 mm) away from center of reel shaft and 10 in.
(25 cm) down (Fig. 37).
• Weight should be just held when screw is
perpendicular to center line of reel shaft.
1. Remove grass catcher and cutting unit from traction
unit; refer to Removal and Installation of Cutting Unit.
2. Remove locknut, reel adjustment screw, Allen head set
screw, and capscrew from left reel bracket. Remove

Page 26
4. If torque wrench is used, there should be 5–10 in-lb
(5.6–11.3 Nm) drag on reel shaft. Rotate the shaft and
repeat check to be sure bearings are aligned in cup and
cone.
5. If bearings need adjustment, locate and remove lock
tab from lockwasher inserted into slot on locknut
(Fig. 38).
4. Use a good grade of medium grit (80) commercial
lapping compound with a water soluble carrier to
assure the compound will be easily washed away at the
completion of the backlapping operation. Dry lapping
compound should be mixed with liquid detergent
(soap) until the material is of free flowing consistency.
Note: Paste-type pre–mixed lapping compound is also
sold in some areas. This is generally used in its original
composition and therefore is not free flowing.

6. Adjust locknut in small increments and check for
proper preload. Bend ears of lockwasher into slots on
locknut when adjustment is completed to secure
locknut (Fig. 38).
Important Do not over–adjust or bearing life will be
affected.
7. Install left reel bracket.
Backlap Operation
5. Operate the lapping machine so the reel turns in a
reverse direction for about three minutes. apply
lapping solution continuously with a paint brush across
the full width of the reel.
Caution
Be careful when lapping the reel because
contact with the reel or other moving parts
can result in personal injury.
6. Again, lightly adjust the bedknife and reel. Then, lap
for approximately two additional minutes. Apply
lapping solution continuously.
7. Wash off all lapping solution.
8. Using newspaper, check for sharpness along the entire
length of each reel blade. If the newspaper cannot be
cut cleanly along the entire length of each blade,
grinding or re–grinding is necessary; refer to Reel and
Bedknife Grinding.
Note: For a better cutting edge, run a file across the front
face of the bedknife when the lapping operation is
completed. This will remove any burr or rough edge that
may have built up on the cutting edge.
Backlap when reel blades and bedknife edge are slightly
rounded and do not cut the grass cleanly with a light reel
to bedknife adjustment. Also backlap after a reel and
bedknife have been reground to establish a land area and
assure a perfect match between reel and bedknife cutting
edge. Backlapping will not correct nicked or severely
rounded reel blades or uneven bedknife wear. Correct
these conditions by repairing, replacing or re–grinding the
components.
1. Using a fine–tooth file, remove high spots from reel
blades. If any blade is bent, straighten by placing a
hammer on one side of blade and tapping on opposite
side.
2. Adjust the reel to bedknife to obtain a light contact;
refer to Reel to Bedknife Adjustment.
3. Connect a lapping machine to the cutting unit with an
extension coupler, and socket.
Reel And Bedknife Grinding
Refer to the TORO GUIDE TO REEL AND ROTARY
MOWER SHARPENING. Copies are available from your
local Toro distributor.
Note: In order to grind the bedknife, it has to be removed
from the cutting unit. The bedknife is then mounted on the
grinding bar (TOR 31397).
Cleaning Mower
It is recommended to wash the cutting unit, transaxle, and
grass basket after each day’s use. Chemicals in the turf
may cause premature deterioration to certain components
if not washed daily.
Important Do not direct “high–pressure” water at oil
seals, bearings, electrical connectors/switches, hot engine,
etc.; contamination of these parts could cause premature
wear.
