A SAFETY INSTRUCTIONS
Improper use or maintenance by the operator or
owner of the mower can still result in injury. To
reduce the potential for any injury, comply with
the following safety instructions.
BEFORE OPERATING
1. Operate the mower only after reading this
manual. A replacement manual is available by
sending complete model and serial number to: The
Toro Company, 8111 Lyndale Avenue South,
Minneapolis, Minnesota 55420; Attn: Publications.
2. Never allow children to operate the mower or
adults to operate it without proper instructions.
3. Become familiar with the controls and know
how to stop the engine quickly.
4, Keep everyone, especially children and pets,
away from the area of operation. Remove sticks,
stones, wire and any other debris that might be
picked up and thrown by the blade.
5. Keep all shields and safety devices in place.
Before operating mower, check it for damage and
abnormal wear. |f a shield, safety device or decal
is defective or damaged, repair or replace it be-
fore operation is commenced.
6. Wear long pants and substantial shoes. Do
not operate mower while wearing sandals, tennis
shoes, sneakers or shorts. Do not wear loose
fitting clothing that could get caught in moving
parts.
7. If long grass will be cut, set height-of-cut in
highest position. After mowing, reinspect the
area and remove all debris. Then lower the height-
of-cut and mow grass again.
8. Gasoline is highly flammable; handle it care-
fully.
A. Use an approved gasoline container.
B. Do not fill fuel tank when engine is hot or
running.
C. Do not smoke while handling gasoline.
D. Fill fuel tank outdoors and up to about
one-half inch (13 mm) from the top of the
tank, not the filler neck.
E. Wipe up any spilled gasoline.
WHILE OPERATING
9. Cutting grass with a rotary mower demands
attention. Always maintain secure footing, bal-
lance and control.
10. Cut grass during the daytime or when there is
adequate artificial light. Cut grass slopes from
side to side. Avoid slopes when grass is wet. If
possible, mow when grass is dry for best results.
11. Keep face, hands and feet away from the
mower housing and cutter blade when the engine
is running. Stay behind the handle until the
engine stops.
12. When operating mower without the bag, the
chute door must be closed. Whenever grass is being
bagged, the engine must be shut off and the chute
door closed before the bag is removed and emptied.
13. If the discharge opening is clogged, shut
engine off and wait for all moving parts to stop.
Disconnect high tension wire from the spark plug
and clear the obstruction with a stick.
14. Since the blade rotates for a few seconds after
throttle control is moved to OFF, stay behind the
handle until all moving parts stop.
15. If a solid object is hit by the blade or if mower
vibrates abnormally, shut engine off immediately
and wait for al' moving parts to stop. Disconnect
high tension wire from spark plug and keep wire
away from plug to prevent possibility of accidental
starting. Check mower for possible damage, bent
blade, an obstruction, or loose part(s). Make all
repairs before using the mower.
16. Stop the engine before adjusting the height-
of-cut.
17. If a gravel driveway, road or side walk must
be crossed, stop the engine so loose sand and
rocks are not thrown.
18. Before leaving the operator's position — behind
the handle — stop the engine and wait for all moving
parts to stop. Do not walk in front of the mower
while the engine is running. Disconnect high tension
wire from spark plug if mower will be unattended.
19. Do not touch any part of the engine while it is
running or shortly after it has been stopped be-
cause the engine will be hot enough to cause a burn.
20. Before the mower is serviced or adjusted, stop
the engine and disconnect high tension wire from
spark plug. Keep the wire away from the plug to
prevent the possibility of accidental starting.
A SAFETY INSTRUCTIONS
MAINTENANCE
21. To assure the mower is in safe operating con-
dition, frequently check, and keep all nuts, bolts
and screws tight. Assure blade bolt is tightened to
50 ft-lb (68 N-m) and engine mounting bolts are
tightened to 16 fi-iD (22 Nm).
22. Perform only those maintenance instructions
described in this manual. If major repairs are ever
needed or if assistance is desired, contact an
Authorized TORO Service Dealer.
23. If mower must be tipped when it is serviced
or adjusted, drain gasoline from the fuel tank.
24. 1f a guard, safety device or safety decal is
damaged, replace the defective part(s) before
operating the mower.

dition; therefore, check it before each use to
assure the bag is not torn or deteriorated. Replace
a defective grass bag.
27. Allow engine to cool before storing mower in
any enclosure such as a garage or storage shed. Do
not store mower near any open flame or where
gasoline fumes may be ignited by a spark.
28. Do not overspeed the engine by changing
governor settings. Recommended speed of the
engine is 2650 rpm. To assure safety and accuracy,
have an Authorized TORO Service Dealer check
engine speed, 2650 rpm, with a tachometer.
29. At the time of manufacture the mower con-
formed to the safety standards in effect for
rotary mowers. To assure optimum performance
and continued safety certification of the mower,
use genuine TORO replacement parts and acces-
sories. Replacement parts and accessories made by
other manufacturers may result in non-con-
formance with the safety standards, and that could
be dangerous.

BEFORE OPERATING
FILL CRANKCASE WITH OIL
The engine does not have oil in the crankcase when
it is shipped from the factory. If engine is started
before oil is added to the crankcase, engine damage
could result. Therefore, before engine is started
for the first time:
1. Position mower on level surface.
2. Clean area around the oil dipstick to prevent
foreign matter from entering the filler hole when
dipstick is removed.
3. Remove dipstick by rotating cap counterclock-
wise (Fig. 9).
Figure 9
1. Filler neck 2 Read dipstick here
4. Slowly pour approximately 20 ounces (0.591 |)
of oil into the filler neck. The engine uses any high
quality detergent oil having the American Petro-
leum Institute — API — “service classification”
MS, SC, SD or SE. The recommended oil to use
is: SAE 10W-30 or 10W-40.
5. Wipe end of dipstick and insert it into filler
neck. Rotate cap fully clockwise to lock. Then
remove the dipstick and check level of oil by
reading the dipstick (Fig. 9). If level of oil is low,
add only enough oil to raise level to FULL mark
on dipstick. DO NOT ADD OIL SO LEVEL RISES
ABOVE FULL MARK BECAUSE ENGINE
COULD BE DAMAGED WHEN IT ISSTARTED.
6. Insert dipstick into filler neck and rotate cap
fully clockwise to lock.
Note: Check level of oil after every 5 operating
hours or each time the mower is used. Initially,
change oil after the first 2 hours of operation;
thereafter, when conditions are normal, change oil
after every 25 hours of operation. However, change
oil more frequently when mower is operated in
dusty or dirty conditions.

FILL FUEL TANK WITH GASOLINE
1. Clean area around fuel tank cap and remove
cap from tank (Fig. 10).
2. Fill fuel tank to within 1/2 inch (13 mm) from
top of the tank with unleaded gasoline. Install fuel
tank cap securely.
3. Wipe up spilled gasoline.
IMPORTANT: Unleaded gasoline is recommended.
If unleaded gasoline is not available, leaded-
regular gasoline can be used. Do not mix any oil
with the gasoline, and never use premium gasoline,
gasoline additives or white gas because engine
damage could result.
Figure 10
1. Fill hole 2 Fuel tank cap
Gasoline 1s a highly flammable fuel for
internal combustion engines, and it is
not recommended for any other use.
Always handle it carefully. Since many
children like the smell of gasoline, keep
it out of their reach because the fumes
are explosive and dangerous to inhale.
Æà To assure the correct volatility, buy only a 30
day supply of gasoline and store the gasoline in a
cool, well-ventilated place; never in the house or
basement. Always use a clean, approved gasoline
container, and keep the cap tight to prevent the
escape of fumes from the container.
Fill fuel tank outdoors, use a funnel or spout to
prevent spilling, and wipe up any gasoline that does
happen to spill. Fill fuel tank only while engine is
cool and not running. Fill the tank to about 1/2
inch (13 mm) from the top so there is room for
expansion of the gasoline. While filling the fuel
tank, stay away from open flame and electrical
spark, and do not smoke.
CONTROLS
Throttle Control (Fig. 11) — The throttle control
is used to stop the engine. The speed of the blade
is also controlled by the movement of the throttle.
Moving throttle forward increases engine speed
and moving it backward decreases engine speed.
When control is in no. |!!! position, engine will run
at maximum rpm.
Figure 11
1. Throttle control
2 Traction control
Traction Control (Fig. 11) — The traction control
has two positions: ENGAGE and DISENGAGE.
Move control to the right and forward to engage
front wheels. Pull control backward into detent
position to disengage front wheels. The detent
holds traction control in DISENGAGE position.
Traction control must be in DISENGAGE detent
before engine can be started.
Recoil Starter (Fig. 12) — Pull fingertip starter to
start the engine.
Figure 12
1. Recoil starter
Height-of-Cut Adjusters (Fig. 13) — Height-of-
cut is adjustable to one of five approximate
settings: 1 inch, 1-1/2 inches, 2 inches, 2-1/2
inches, or 3 inches (25, 38, 51, 64 and 76 mm). In
addition, front wheels have a 5/8 inch (16 mm)
setting that can be used with the 1 inch (25 mm)
rear wheel setting. When cutting thatch or heavy,
thick grass, raise rear wheel one setting above the
front wheel setting to assure optimum power to
the blade.

OPERATING INSTRUCTIONS
ADJUST HEIGHT-OF-CUT
The height-of-cut is adjustable from approxi-
mately 1 to 3 inches (25 to 76 mm) in 1/2 inch
(13 mm) increments, and letters cast into the
housing represent each graduated increment.
а = 1 Inch (25 mm)
b = 1-1/2 Inches (38 mm)
с = 2 Inches (51 mm)
d = 2-1/2 Inches (64 mm)
e = 3 Inches (76 mm)
1. dA Assure engine is not running before adjust-
ing height-of-cut because contact with the blade
will cause personal injury.
2. Place thumb against height-of-cut adjuster and
fingers on outside of wheel (Fig. 13).
3. Raise mower housing until wheel is off the
ground. Squeeze height-of-cut adjuster toward
wheel so its locating pin disengages notch in mower
housing. Then pivot the wheel and adjuster to
the desired height-of-cut and release adjuster so
locating pin engages notch in housing.
OPERATING INSTRUCTIONS
OPERATING CHARACTERISTICS AND TIPS
The Rear Bagger has a 9.02 cubic inch (147.8 cc)
engine that delivers the blade turning force nec-
essary to produce a good quality-of-cut.
The mower can be used with or without the grass
bag: refer to Bagging, page 10 and Mowing With-
out the Bag, page 12.
To use the mower for bagging grass, install the bag,
open the chute door in mower housing and start
the engine. Notice that the grass bag expands at
the sides and top. This expansion by the bag is
caused by the air currents generated by the blade,
flowing through the bag. As grass is cut and dis-
charged into the bag, the air currents through the
bag decrease gradually as it is being filled. While
the bag is expanded, grass can be cut. Stop the
engine and empty the bag when it is no longer
expanded.
The mower is equipped with a rear shield (Fig. 14),
which helps protect from objects that might be
thrown rearward and from possible contact with
the blade. Because of its flexible design, maneu-
verability of the mower is unaffected. Never re-
move the rear shield because it is a safety device,
designed for your protection. If the shield is ever
damaged, replace it before operating the mower.
Figure 14
1. Rear shield
After the mower is used, it must be cleaned and
maintained so it is ready for the next cutting. Use
the wash-out port to clean the underside of the
mower housing. However, avoid getting water
directly onto the engine or electrical connections
because damage could result. Periodically, check
the blade, and assure the blade bolt is tightened to
50 ft-lb (68 N'm). The oil in the crankcase must
be changed after the first 2 hours of operation and
after every 25 hours thereafter. Assure level of oil
is always in the SAFE range, as shown on the
dipstick; however, never fill oil over the FULL
mark because engine damage could result. After
10
every 25 hours of engine operation the air cleaner
must be cleaned. If mower is used in dusty or
dirty conditions check air cleaner more frequently.
Whenever the mower is being operated, adjusted or
maintained, the safety instructions at the front of
this manual must be kept in mind. Safe operation
is your responsibility.
BAGGING
The Rear Bagger discharges grass clippings into a
large, 2-1/4 bushel (0.079 m2) bag, and because
of the rear bagging feature, both sides of the mower
can be used for trimming. Bagging is most effec-
tive when engine is running at maximum speed and
only about 1/3 of grass blade is being cut. If an
excessive amount of grass is being cut off, the
mower can plug and cause the engine to stall. If
long grass must be cut, adjust mower to the highest
height-of-cut; then cut the grass. Follow this by
lowering the height-of-cut and cutting the grass
again.
A...
The grass bag material will contain and
catch the majority of foreign objects,
such as small stones and other similar
debris. The bag material, however, is
subject to normal wear and deteriora-
tion. So check the bag frequently, and
if it is defective, install a new, genuine
TORO replacement bag that has this
warning or a similar one.

Then lift bag straight up so clippings stay in the
bag rather than falling out the opening (Fig. 18).
Figure 18
IMPORTANT: If chute door of mower cannot be
closed because grass clippings clog the discharge
area, move chute door gently back and forth. Do
this until clippings are pushed into the bag and
chute door can be closed completely. DO NOT
FORCE THE CHUTE DOOR CLOSED because
door or handle may be damaged by the compacted
grass.
Never open the chute door when grass
bag is removed from the mower and
engine is running. Grass clippings and
other debris will be discharged with
enough force to cause personal injury.
6. To dump grass out of bag, open door at front
of bag. While shaking the bag, gradually tip it
forward so grass sifts out (Fig. 19). Do not try to
dump all the grass at once.
7. Reinstall bag by repeating steps 3 and 4.

MOWING WITHOUT THE BAG
The Rear Bagger can be used for shredding dry
grass or leaves. However, this is effective when only
about 1/4 of the grass blade is cut. During the
shredding process, the blade slices the cut pieces of
grass again and again, so very fine particles of grass
are deposited on the lawn. These fine grass
clippings eventually decompose.
To mow without the bag:
1. dA Assure engine is not running and cutter
blade is not moving.
2. Squeeze lockout lever, move chute door handle
fully forward, and release lever into catch (Fig. 20).

The chute door of mower housing is now closed
and mower is ready for use.
Note: |f desired, the grass bag may remain on
the mower.
CAUTION
Never open chute door when mowing
without bag attached because grass clip-
pings or other debris will be discharged
with enough force to cause personal
injury,

MAINTENANCE
SERVICING AIR CLEANER
The air cleaner element must be cleaned after every
25 hours of engine operation if the engine is
operated in clean air conditions. The element must
be cleaned more frequently, however, when mower
is operated in dusty or dirty conditions.
1: A Assure engine is not running, traction con-
trol is in DISENGAGE detent and high tension wire
is pulled off spark plug.
2. Remove screw and cover to expose air cleaner.
Remove cover (Fig. 29) and clean dirt from inside
and outside surfaces.
Figure 29
1. Air filter screw 2. Air filter cover
3. Look at top of air cleaner element (Fig. 30). If
it is dirty, the element must be removed from air
cleaner body (Fig. 30) and cleaned.
A. WASH element in a solution of liquid soap
and warm water. Squeeze the element to
remove dirt. Do not twist element be-
cause It may tear.
B. DRY the element by wrapping it in a clean
rag. Squeeze the rag and element until
element is dry.
C. SATURATE element with 5 teaspoons
(25 ml) SAE 30 engine oil. Squeeze ele-
ment to remove excess oil and to distribute
the oil thoroughly. A damp element is
desirable,
D. Place element and spacer into the air clean-
er body (Fig. 30). Assure narrow edge of
spacer is parallel with side of air cleaner
body.
4. Install cover on air cleaner body and assure
cover and element form a seal. Mount air cleaner
assembly on top of carburetor with long screw
(Fig. 29).
Figure 30
1. Air cleaner element 12. Air cleaner body
IMPORTANT: Do not operate engine without air
cleaner element because extreme engine wear and
damage will likely result.
REPLACING SPARK PLUG
Recommended spark plug to use is a Champion
RJ-8 or equivalent, and correct air gap is 0.030
of an inch (0.76 mm). Since air gap between center
and side electrodes of the spark plug increases
gradually during normal engine operation, remove
plug after every 25 hours of engine operation and
check its condition.
1 A Assure engine is not running. Then pull
high tension wire off spark plug.
2. Clean area around spark plug so foreign
matter does not fall into cylinder when plug is
removed.
(Fig. 31).

MAINTENANCE
IMPORTANT: A cracked, fouled or dirty spark
plug must be replaced. Do not sand blast, scrape
or clean electrodes, because grit may eventually
release from the plug and fall into the cylinder.
The result will likely be engine damage.
3. Set air gap between electrodes at 0.030 of an
inch (0.76 mm) (Fig. 32). Install the correctly
gapped spark plug with gasket and tighten plug

DRAINING GASOLINE FROM FUEL TANK
A CAUTION
Since gasoline is highly flammable, drain
it outdoors and make sure engine is cool
to prevent a potential fire hazard. Wipe
up any gasoline that may have spilled.
Do not drain gasoline near any open
flame or where gasoline fumes may be
ignited by a spark. Do not smoke a
cigar, cigarette, or a pipe when handling
gasoline.
1. А Assure engine is not running, traction con-
trol is in DISENGAGE detent and high tension
wire is pulled off spark plug.
2. Remove cap from fuel tank.
3. Using a pump-type syphon, drain gasoline into
a clean gas can. This is the only recommended
method of draining gasoline.
CHANGING CRANKCASE OIL
To prevent premature engine failure due to low oll
16
level, check oil level after every 5 hours of
operation or each time mower is used. Change oil
after the first two hours of operation; thereafter,
under normal conditions, change oil after every 25
hours of operation. However, change oil more
frequently when engine is operated in dusty or
sandy conditions or engine damage will occur. If
possible, run engine just before changing oil be-
cause warm oil flows better and carries more con-
taminants than cold oil.
1. Pull high tension wire off spark plug. Assure
that wire does not contact plug accidentally
(Fig. 31).
2 A Drain gasoline from fuel tank to prevent a
potential hazard.
3. Tip mower on its right side and remove oil
drain plug (Fig. 33).
4. Tip mower upright over drain pan and allow
oil to drain.

Draining Gasoline, page 16.
3. Tip mower on its right side (Fig. 34), which is
opposite Its spark plug side, and allow it to remain
tipped for a short time. Avoid rotating the blade
when mower is tipped because starting problems
may result.
MAINTENANCE
Figure 34
4. Examine cutting ends of the blade carefully,
especially where the flat and curved parts ofthe
blade meet (Fig. 35A). Since sand and abrasive
material can wear away the metal that connects
the flat and curved parts of the blade, check the
blade before using the mower. If any wear is
noticed (Fig. 35B), replace the blade: refer to
Sharpening or Replacing Cutter Blade, page 17.

3. Tip mower on its right side, which is opposite
its spark plug side and allow it to remain tipped for
a short time. Avoid rotating the blade when mower
is tipped because starting problems may result.
4, Grasp end of blade using a rag or thickly
padded glove. Remove blade bolt, lockwasher and
blade (Fig. 36).
Figure 36
1. Blade bolt and lockwasher
Note: To assure optimum cutting performance,
install a new blade at the start of the cutting
season. During the year, file down small nicks to
maintain a fine cutting edge.
5. Using a file, sharpen cutting edge at both
ends of the blade (Fig. 37).
IMPORTANT: Sharpen top side of blade and
maintain original cutting angle to assure a sharp
cutting edge (Fig. 37). The blade will remain
balanced if same amount of material is removed
from both cutting edges.
‘
Figure 37
1. Sharpen at original angle

MAINTENANCE
6. Check balance of blade by putting it on a
blade balancer. A balanced blade will stay in a
horizontal position on the balancer. By contrast,
a blade that is not balanced will settle to the
heavy side. If blade is not balanced, file some
metal off heavy “end” of the blade, not off the
cutting edge. Then check the blade balance again.
Note: An inexpensive blade balancer can be
purchased at a hardware store.
7. Install sharp, balanced blade with lockwasher
and blade bolt. Sail part of the blade must point
toward the mower housing to assure correct in-
stallation. Tighten blade bolt to 50 ft-Ib (68 N-m).
8. Set mower upright.
CLEANING MOWER HOUSING
To assure a good cut and efficient grass bagging,
underside of mower housing and inside of dis-
charge area must be kept clean.
1. ÁN Assure engine is not running, traction con-
trol is in DISENGAGE detent and high tension
wire is pulled off the spark plug.
2. 4A Drain gasoline from fuel tank: refer to
Draining Gasoline, page 16.

ADJUSTING CARBURETOR
The carburetor has been set at the factory, but an
occasional adjustment may be required. How-
ever, do not make unnecessary carburetor adjust-
ments, because factory settings are usually correct.
An adjustment may be required to compensate for
differences in fuel, temperature, and altitude.
IMPORTANT: Air cleaner must be installed on
the engine whenever carburetor is being adjusted.
The air cleaner mounting screw must also be in-
stalled when engine is run. Fuel tank must be
half full of gasoline to get best carburetor adjust-
ment.
1. Needle Valve — Close valve by gently rotating
it clockwise (Fig. 39).
IMPORTANT: Do not close needle valve too tight,
because valve and seat in carburetor will likely
be damaged.
Figure 39
1. Needle valve 2 Idle adjusting screw
2. Open needle valve by rotating 1-1/2 turns
counterclockwise,
Note: The needle valve setting is approximate:
however, the setting will allow engine to be
started so carburetor can be fine tuned.
3. Start engine and let it warm up for approxi-
mately two minutes. Next, move throttle control
to no. Ill position.

time until engine starts to lose speed. Let engine
react to each 1/8 turn setting.
5. Rotate needle valve counterclockwise (out-
ward) 1/8 turn at a time until engine first starts
to run rough. Let engine react to each 1/8 turn
setting.
6. Rotate needle valve clockwise (inward) very
slowly until engine starts to run smoothly. This
setting, under no load, may be slightly rich; how-
ever, the slightly rich setting will assure proper
operation when engine is under load.
7. Move throttle control to no. |. Next,
rotate idle adjusting screw until engine speed is
1750 rpm.
Note: Rotate idle adjusting screw clockwise to
increase idle rpm. By contrast, rotate idle adjust-
ing screw counterclockwise to decrease idle rpm.
8. Check carburetor adjustment by quickly mov-
ing throttle control from no. | to no. Ill.
Engine speed should increase without hesitation. If
engine tends to stall or die out, rotate needle valve
1/8 turn counterclockwise until engine accelerates
smoothly.
9. After carburetor is adjusted, shut engine off.
If mower will not be used immediately, pull high
tension wire off spark plug and install end in
notched hole to prevent accidental starting.
ADJUSTING THROTTLE CONTROL
If engine does not stop or start, or if throttle
control is replaced, an adjustment may be re-
quired.
1. Pull high tension wire off spark plug and install
end in notched hole. Move handle-mounted throttle
control to full OFF position (Fig. 40).
2. Loosen cable clamp screw until throttle cable
is free to slide (Fig. 40).
3. Move throttle arm to the right until it contacts
grounding bracket.
4. Pull throttle cable slightly to remove any
slack: then tighten cable clamp screw.

CHECKING GEAR CASE
The gear case is filled with oil and sealed at the
factory. However, check gear case periodically for
oil leaks between sides of case and axle (Fig. 41).
If oil leak is excessive or continuous, have mower
inspected by an Authorized TORO Service Dealer.
Slight leakage may be occurring which will not be
obvious. Therefore, check the oil level in the gear
case at least every 25 hours of operation.

Note: Only the gear oil recommended should be
used. Substitute gear oil will cause premature
failure of the gear case components. A Plews type
oil container or any other container with a small
tip can be used for installation of gear oil. Clean
the container thoroughly before filling with gear
oil to avoid contaminating gear case.
7. Install plastic plug. Take care not to over-
tighten so plug threads will not strip out.
8. Install belt, rotate gear case forward and mount
stop screw and bracket assembly (Fig. 42).
9. Install POW-R-DRIVE cover and set height-of-
cut to desired setting.
ADJUSTING TRACTION CONTROL
If traction control does not engage or disengage the
front wheels, an adjustment may be required.
1. A Assure engine is not running and high tension
wire is pulled off spark plug and installed in
notched hole.
2. Remove three screws holding POW-R-DRIVE
cover and put cover aside.
Note: Check the stop screw (Fig. 46) to be sure it
contacts tab at front of gear case, If contact is not
