of the brak e . T he main reasons for loss of
control are:

T his mac hine meets or ex ceeds CEN standard
EN 836:1997, ISO standard 5395:1990 (when
appropriate decals applied), and ANSI B71.4-2004
specifications in effect at the time of production
when equipped with rear w eight as listed in the
implement Operator’ s Man ual.

Improper use or maintenance b y the operator or
o wner can result in injur y . T o reduce the potential
for injur y , comply with these safety instr uctions
and alw a ys pa y attention to the safety aler t
symbol, whic h means CA UTION , W ARNING ,
or D ANGER—“personal safety instr uction. ”
F ailure to comply with the instr uction ma y result
in personal injur y or death.

Safe Operating Practices

T he follo wing instr uctions are from the CEN
standard EN 836:1997, ISO standard 5395:1990,
and ANSI B71.4-2004.

Training

• R ead the Operator’ s Manual and other training
material carefully . If the operator or mec hanic
can not read the languag e of this man ual it
is the o wner’ s responsibility to explain this
material to them.

• Be familiar with the controls , safety signs , and
the proper use of the equipment.

• Nev er allo w c hildren or people unfamiliar with
these instr uctions to use or ser vice the mo w er .
Local regulations ma y restrict the ag e of the
operator .

• Nev er mo w while people , especially c hildren,
or pets are nearb y .

• K ee p in mind that the operator or user is
responsible for accidents or hazards occur ring
to other people or their proper ty .

• Do not car r y passeng ers .

• All operators and mec hanics should seek and

obtain professional and practical instr uction.
T he o wner is responsible for training the users .
Suc h instr uction should emphasize:

– the need for care and concentration when

w orking with ride-on mac hines;

– control of a ride-on mac hine sliding on a

slope will not be reg ained b y the application

◊ insufficient wheel g rip;

◊ being dri v en too fast;

◊ inadequate braking;

◊ the type of mac hine is unsuitable for its

task;

◊ lac k of a w areness of the effect of

g round conditions , especially slopes;

◊ incor rect hitc hing and load distribution.

• T he o wner/user can prev ent and is responsible
for accidents or injuries occur ring to himself
or herself , other people , or proper ty .

Preparation

• W hile mo wing, alw a ys w ear substantial
footw ear , long trousers , hard hat, safety glasses ,
and hearing protection. Long hair , loose
clothing, or jew elr y ma y g et tangled in mo ving
par ts . Do not operate the equipment when
barefoot or w earing open sandals .

• T horoughly inspect the area where the
equipment is to be used and remo v e all objects
whic h ma y be thro wn b y the mac hine .

• W ar ning-Fuel is highly flammable . T ak e the
follo wing precautions:

– Store fuel in containers specifically designed

for this pur pose .

– R efuel outdoors only and do not smok e

while refueling .

– Add fuel before star ting the engine . Nev er

remo v e the cap of the fuel tank or add fuel
while the engine is r unning or when the
engine is hot.

– If fuel is spilled, do not attempt to star t the

engine but mo v e the mac hine a w a y from
the area of spillag e and a v oid creating any
source of ignition until fuel v apors ha v e
dissipated.

– R e place all fuel tanks and container caps

securely .

• R e place faulty silencers/m ufflers .

• Ev aluate the ter rain to deter mine what

accessories and attac hments are needed to
properly and safely perfor m the job . Only use

5

accessories and attac hments appro v ed b y the
man ufacturer .

Checking the Interlock
System

T he pur pose of the safety interloc k system is to
prev ent the engine from cranking or star ting unless
the traction pedal is in neutral and the PTO switc h
is in the Off position. In addition, the engine will
stop when:

• the PTO control is eng ag ed with the operator
off the seat;

• R eplace s witches ev er y tw o y ear s
r egardless of whether they ar e operating
pr oper l y or not.

1. Mo v e PTO switc h to Off position and remo v e
foot from traction pedal so it is fully released.

2. R otate the ignition k ey to Star t. Engine should
crank. If engine cranks , proceed to ste p 3 .
If engine does not crank, there ma y be a
malfunction in the interloc k system.

3. Raise off the seat and eng ag e the PTO switc h
while the engine is r unning . T he engine should
stop within 2 seconds . If engine stops , the
switc h is operating cor rectly; thus , proceed
to ste p 4 . If engine does not stop , there is a
malfunction in the interloc k system.

4. Raise off the seat and de press the traction
pedal while engine is r unning and the PTO
lev er is diseng ag ed. T he engine should stop
within 2 seconds . If engine stops , the switc h is
operating cor rectly; thus , proceed to ste p 5 If

in the interloc k system.

• the traction pedal is de pressed with the
operator off the seat;

• the traction pedal de pressed with the parking
brak e eng ag ed.

Pushing or Towing the
Machine

In an emerg ency , the mac hine can be pushed or
to w ed for a v er y shor t distance . Ho w ev er , T oro
does not recommend this as standard procedure .

34

Important: Do not push or to w the
machine f aster than 2 to 3 mph because the
transmission may be dama ged. If the machine
must be mo v ed a considera ble distance,
transpor t it on a tr uck or trailer . W henev er the
machine is pushed or to w ed, the by-pass v alv e
must be open.

1. Loosen the knob and remo v e the access
co v er at the rear of the seat mounting plate
( Figure 29 ).

Important: R unning the machine with
the by-pass v alv e open will cause the
transmission to o v erheat.

4. Install the access co v er .

Standard Control Module
(SCM)

T he Standard Control Module is a potted
electronic device produced in a one size fits all
configuration. T he module uses solid state and
mec hanical components to monitor and control
standard electrical features required for safe
product operation.

T he module monitors inputs including neutral,
parking brak e , PTO , star t, bac klap , and high
temperature . T he module energizes outputs
including PTO , Star ter , and ETR (energize to r un)
solenoid.

T he module is di vided into inputs and outputs .
Inputs and outputs are identified b y yello w LED
indicators mounted on the printed circuit board.

Figure 29

1. Access cover knob

2. Press and hold the pins located in the center
of the 2 c hec k v alv e assemblies in the top of
the transmission ( Figure 30 ) while pushing or
to wing the mac hine . Figure 30 is sho wn with
seat and seat mounting plate remo v ed.

Figure 30

1. Transmission check valve by-pass pins (2)

T he star t circuit input is energized b y 12 VDC .
All other inputs are energized when the circuit is
closed to g round. Eac h input has a LED that is
illuminated when the specific circuit is energized.
Use the input LED’ s for switc h and input circuit
troubleshooting .

Output circuits are energized b y an appropriate
set of input conditions . T he three outputs include
PTO , ETR, and ST AR T . Output LED’ s monitor
rela y condition indicating the presence of v oltag e
at one of three specific output ter minals .

Output circuits do not deter mine output device
integ rity so electrical troubleshooting includes
output LED inspection and con v entional device
and wire har ness integ rity testing . Measure
disconnected component impedance , impedance
through wire har ness (disconnect at SCM), or b y
temporarily test energizing the specific component.

T he SCM does not connect to an exter nal
computer or hand held device , can not be
re-prog rammed, and does not record inter mittent
fault troubleshooting data.

3. Star t the engine momentarily after the re pairs
are completed and mak e sure the pins are in
the full diseng ag ed (fully up) position.

T he decal on the SCM only includes symbols .
T hree LED output symbols are sho wn in the
output bo x. All other LED’ s are inputs . T he c har t
belo w identifies the symbols .

Figure 31

Here are the logical troubleshooting ste ps for the
SCM device .

1. Deter mine the output fault y ou are tr ying to
resolv e (PTO , Star t, or ETR).

2. Mo v e k ey switc h to the On position and ensure
the red po w er LED is illuminated.

3. Mo v e all input switc hes to ensure all LED’ s

Operating Tips

• Practice dri ving the mac hine before initial
operation because it has a h y drostatic
transmission and its c haracteristics are different
than some turf maintenance mac hines . Some
points to consider when operating the mac hine
and dec k are the transmission, engine speed,
load on the cutting blades , and the impor tance
of the brak es .

• T o maintain enough po w er for the mac hine
and dec k while mo wing, regulate traction
pedal to k ee p engine r pm high and somewhat
constant. A g ood r ule to follo w is: decrease
g round speed as the load on the cutting blades
increases; and increase g round speed as load
on the blades decreases . T his allo ws the
engine , w orking with the transmission, to sense
the proper g round speed while maintaining
high blade tip speed necessar y for g ood
quality-of-cut. T herefore , allo w traction pedal
to mo v e upw ard as engine speed decreases ,
and de press pedal slo wly as speed increases . By
comparison, when dri ving from one w ork area
to another -with no load and dec k raised-ha v e
throttle in F ast position and de press traction

pedal slo wly but fully to attain maxim um
g round speed.

• Another c haracteristic to consider is the
operation of the brak es . T he brak es can be
used to assist in tur ning the mac hine; ho w ev er ,
use them carefully , especially on soft or w et
g rass because the turf ma y be tor n accidentally .
T he brak es can be used to control the direction
of the dec k when trimming along fences or
similar objects . T he other benefit of the brak es
is to maintain traction. F or example; in some
slope conditions , the uphill wheel slips and
loses traction. If this situation occurs , de press
uphill brak e pedal g radually and inter mittently
until the uphill wheel stops slipping; thus ,
increasing traction on the do wnhill wheel. If
inde pendent braking is not desired, eng ag e the
lev er on left brak e pedal with right pedal. T his
pro vides sim ultaneous braking at both wheels .

• Before stopping the engine , diseng ag e all
controls and mo v e the throttle to the Slo w
position. Mo ving the throttle to the Slo w
position reduces high engine speed, noise , and
vibration. T ur n the ignition k ey to the Off
position to stop the engine .

and bushings after ev er y 50 hours of operation.
Bearings and bushings m ust be lubricated daily
when operating conditions are extremely dusty and
dir ty . Dusty and dir ty operating conditions could
cause dir t to g et into the bearings and bushings ,
resulting in accelerated w ear . Lubricate g rease
fitting immediately after ev er y w ashing, reg ardless
of inter v al specified.

Apply a liberal coating of g rease to the c hec k v alv e
pins once eac h year ( Figure 33 ). Also g rease the
bearings in the rear axle ev er y 500 hours , or yearly ,
whic hev er comes first (not sho wn).

Note: Bearings rarely fail from defects in

materials or w orkmanship . T he most common
reason for failure is moisture and contamination
w orking its w a y past the protecti v e seals . Bearings
that are g reased will rely upon regular maintenance
to purg e har mful debris from the bearing
area. Sealed bearings rely on an initial fill of
special g rease and a robust integ ral seal to k ee p
contaminants and moisture out of the rolling
elements .

T he sealed bearings require no lubrication or shor t
ter m maintenance . T his minimizes routine ser vice
required and reduces the potential of turf damag e
due to g rease contamination. T hese sealed bearing
pac kag es will pro vide g ood perfor mance and life

42

under nor mal use , but periodic inspections of
bearing condition and seal integ rity should be
conducted to a v oid do wntime . T hese bearings
should be inspected seasonally and re placed
if damag ed or w or n. Bearings should operate
smoothly with no detrimental c haracteristics suc h
as high heat, noise , looseness or indications of
cor rosion (r ust).

Due to the operating conditions these bearing/seal
pac kag es are subject to (i.e . sand, turf c hemicals ,
w ater , impacts , etc .) they are considered nor mal
w ear items . Bearings that fail due to causes other
than defects in materials or w orkmanship are
typically not co v ered under w ar ranty .

Initially , re place the h y draulic oil filter after the
first full da y’ s operation.

Important: Do not ex ceed 10 hour s or y ou
will dama ge the h y draulic system.

R e place the filter after ev er y 150 hours and oil
after ev er y 1500 hours .

w ar med up . Using proper w eight h y draulic oil in
system will minimize this condition.

Note: Many h y draulic fluids are almost colorless ,
making it difficult to spot leaks . A red dye additi v e
for the h y draulic system oil is a v ailable in 2/3 oz.
(20 ml) bottles . One bottle is sufficient for 4-6
g al (15-22 1) of h y draulic oil. Order par t n umber
44-2500 from y our authorized T oro distributor .

Adjusting the
Counterbalance Pressure

F or best perfor mance , the cutting unit bounce
on unev en turf is minimal and it does not ride
hea vily o v er flat ter rain. If scalping occurs or the
cut is unev en from side to side , there ma y be too
m uc h w eight on the dec k and the w eight ma y ha v e
to be transfer red to the mac hine: i.e . increased
counterbalance pressure .

By contrast, if too m uc h w eight is transfer red to
the mac hine , the dec k will bounce ex cessi v ely and
the cut will be unev en. If the cutting unit does
not perfor m properly , adjust the counterbalance
pressure as follo ws:

1. T o mak e sure the fluid is w ar m, operate the
mac hine for 15 min utes prior to adjusting the
counterbalance pressure .

2. Ensure that the parking brak e is set, the PTO
switc h is in the Off position, and the lift lev er
is in the Float position.

3. Connect a pressure g aug e to the test por t
behind the left lift cylinder ( Figure 67 ).
