• R ead the Operator’ s Manual and other training
material carefully . 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 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 himself or herself , other people , or proper ty .
• Do not car r y passeng ers .
• All dri v ers 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:
◊ 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

– 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 tank and container caps
securely .
– 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
of the brak e . T he main reasons for loss of
control are:
◊ insufficient wheel g rip;
◊ being dri v en too fast;
• R e place faulty silencers/m ufflers .
• Before using, alw a ys visually inspect to see that
the blades , blade bolts , and cutting assembly
are not w or n or damag ed. R e place w or n or
damag ed blades and bolts in sets to preser v e
balance .

Operating Characteristics
Practice dri ving the mac hine because it has a
h y drostatic transmission and its c haracteristics are
different than many turf maintenance mac hines .
Some points to consider when operating the
traction unit, cutting unit, or other implements are
30
Page 31

the transmission, engine speed, load on the cutting
blades or other implement components , and the
impor tance of the brak es .
T o maintain enough po w er for the traction unit
and implement while operating, regulate the
traction pedal to k ee p the engine RPM high and
somewhat constant. A g ood r ule to follo w is to
decrease the g round speed as the load on the
implement increases , and increase the g round
speed as the load decreases .
T his pr oduct is designed to dri v e objects
into the g r ound wher e they lose energ y
quickl y in g rass ar eas. Ho w ev er , car eless
operation, combined with ter rain ang le,
ricochets, or impr oper l y positioned safety
guard can lead to thr o wn object injuries.
• W hen a per son or pet appear s suddenl y
in or near the mo wing ar ea, stop mo wing .
T herefore , allo w the traction pedal to mo v e
bac kw ard as the engine RPM decreases , and
de press the pedal slo wly as the RPM increases . By
comparison, when dri ving from one w ork area to
another , with no load and cutting unit raised, ha v e
the throttle in the F ast position and de press the
traction pedal slo wly but fully to attain maxim um
g round speed.
T he flo w di vider enhances traction dri v e
perfor mance in compromised operating
conditions . T he flo w di vider is for use in lo w speed
rang e only . W hen approac hing an area kno wn to
cause wheel spin, de press and hold flo w di vider
switc h until completely past the area. If a tire spins
while climbing or maneuv ering on slopes , de press
switc h and slo wly dri v e out of area. If both a front
and rear wheel spins , the steering brak e can be
feathered to transfer the tor que from the spinning
wheels to opposite front wheel.
Another c haracteristic to consider is the operation
of the pedals that are connected to 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 . Another 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 the
uphill tur n pedal g radually and inter mittently until
the uphill wheel stops slipping, thus , increasing
traction on the do wnhill wheel.
• Do not r esume mo wing until the ar ea is
clear ed.
Before stopping the engine , diseng ag e all controls
and mo v e the throttle to Slo w . Mo ving the throttle
to Slo w reduces high engine RPM, noise , and
vibration. T ur n the k ey to Off to stop the engine .
Before transpor ting the mac hine , raise the cutting
units and secure the transpor t latc hes ( Figure 31 ).
Figure 31
1. Transport latch (wing cutting units)
Operating Tips
Mow When Grass is Dry
Use extra care when operating the mac hine on
slopes . Mak e sure that the seat latc h is properly
secured and the seat belt is buc kled. Dri v e slo wly
and a v oid shar p tur ns on slopes to prev ent roll
o v ers . F or steering control, the cutting unit m ust
be lo w ered when g oing do wnhill.
Mo w either in the late mor ning to a v oid the dew ,
whic h causes g rass clumping, or in late after noon
to a v oid the damag e that can be caused b y direct
sunlight on the sensiti v e , freshly mo w ed g rass .
31
Page 32

Select the Proper Height-of-Cut
Setting to Suit Conditions
R emo v e appro ximately 1 inc h (25 mm) or no
more than 1/3 of the g rass blade when cutting . In
ex ce ptionally lush and dense g rass , y ou ma y ha v e
to raise the height-of-cut to the next setting .
Mow at Proper Intervals
Under most nor mal conditions y ou will need to
mo w appro ximately ev er y 4-5 da ys . But remember ,
g rass g ro ws at different rates at different times .
T his means that in order to maintain the same
height-of-cut, whic h is a g ood practice , y ou will
need to cut more frequently in early spring; as the
g rass g ro wth rate slo ws in mid summer , cut only
ev er y 8-10 da ys . If y ou are unable to mo w for
an extended period due to w eather conditions or
other reasons , mo w first with the height-of-cut at
a high lev el; then mo w ag ain 2-3 da ys later with a
lo w er height setting .
Always Mow with Sharp Blades
Figure 32
1. Deck lift cylinder 2. Foam deck pad
Cutting Unit Pitch
W e recommend a blade pitc h of 1/4 inc h (6 mm).
A pitc h larg er than 1/4 inc h (6 mm) will result
in less po w er required, larg er clippings , and a
poorer quality of cut. A pitc h less than 1/4 inc h
(6 mm) will result in more po w er required, smaller
clippings and a better quality of cut.
A shar p blade cuts cleanly and without tearing
or shredding the g rass blades lik e a dull blade .
T earing and shredding causes the g rass to tur n
bro wn at the edg es whic h impairs g ro wth and
increases susce ptibility to diseases .
Transporting
Use the transpor t latc hes when transpor ting o v er
long distances , rough ter rain, or when trailering .
After Operating
T o ensure optim um perfor mance , clean the
underside of the mo w er housing after eac h use .
If residue is allo w ed to build up in the mo w er
housing, cutting perfor mance will decrease .
Also , remo v e any debris whic h ma y ha v e collected
betw een the dec k lift cylinders and the foam dec k
pads ( Figure 32 ).

Lubrication
Greasing the Bearings and
Bushings
T he mac hine has g rease fittings that m ust be
lubricated regularly with No . 2 General Pur pose
Lithium Base Grease . If the mac hine is operated
under nor mal conditions , lubricate all bearings
and bushings after ev er y 50 hours of operation or
immediately after ev er y w ashing .
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
Figure 33
are g reased will rely upon regular maintenance to
purg e har mful debris from the bearing area. Sealed
bearings , suc h as the castor wheel 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
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 .
Note: Bearing life can be neg ati v ely affected
b y improper w ash do wn procedures . Do not
w ash do wn the unit when it is still hot and a v oid

Inspecting and Sharpening
the Cutter Blade(s)
A w or n or dama ged blade can br eak, and
a piece of the blade could be thr o wn into
the operator’ s or bystander’ s ar ea, r esulting
in serious per sonal injur y or death. T r ying
to r epair a dama ged blade may r esult in
discontin ued safety cer tification of the
pr oduct.
lev er in the Off position, stop the engine , and
remo v e the ignition k ey .
2. Examine the cutting ends of the blade carefully ,
especially where the flat and cur v ed par ts of
the blade meet ( Figure 93 ). Since sand and
abrasi v e material can w ear a w a y the metal that
connects the flat and cur v ed par ts of the blade ,
c hec k the blade before using the mo w er . If
w ear is noticed ( Figure 93 ), re place the blade .
• Inspect the blade periodicall y f or w ear
or dama ge.
• Nev er tr y to straighten a blade that is
bent or w eld a br ok en or crack ed blade.
• R eplace a w or n or dama ged blade.
T w o areas m ust be considered when c hec king and
ser vicing the cutter blade-the sail and the cutting
edg e . Both cutting edg es and the sail, whic h is
the tur ned up por tion opposite the cutting edg e ,
contribute to a g ood quality-of-cut. T he sail is
impor tant because it lifts the g rass up straight,
thereb y producing an ev en cut. Ho w ev er , the sail
will g radually w ear do wn during operation, and
this condition is nor mal. As the sail w ears do wn,
the quality-of-cut will deg rade somewhat, although
the cutting edg es are shar p . T he cutting edg e of
the blade m ust be shar p so that the g rass is cut
rather than tor n. A dull cutting edg e is evident
when the tips of the g rass appear bro wn and
shredded. Shar pen the cutting edg es to cor rect
this condition.
1. P osition the mac hine on a lev el surface . Raise
the cutting unit, eng ag e the parking brak e ,
put the traction pedal in neutral, put the PTO
Figure 93
1. Cutting Edge 3. Wear/slot Forming
2. Curved Area 4. Crack
3. Examine the cutting edg es of all of the blades .
Shar pen the cutting edg es if they are dull or
nic k ed. Shar pen only the top of the cutting
edg e and maintain the original cutting angle to
mak e sure of shar pness ( Figure 94 ). T he blade
will remain balanced if the same amount of
metal is remo v ed from both cutting edg es .

If the blade is allo w ed to w ear , a slot
will f or m betw een the sail and flat par t
of the blade ( Figur e 93 ). Ev entuall y a
piece of the blade may br eak of f and be
thr o wn fr om under the housing , possibl y
r esulting in serious injur y to y ou or
bystander s.
• Inspect the blade periodicall y f or
w ear or dama ge.
• Nev er tr y to straighten a blade that
is bent or w eld a br ok en or crack ed
blade.
• R eplace a w or n or dama ged blade.

Note: R emo v e the blades and shar pen them
on a g rinder . After shar pening the cutting
edg es , install the blade with the anti-scalp
cup and blade bolt; refer to R emo ving and
Installing the Cutter Blade(s).
5. R otate the blades until the ends face forw ard
and bac kw ard. Measure from the floor to the
front tip of the cutting edg e . R emember this
dimension. T hen rotate the same blade so
that the opposite end is forw ard, and measure
ag ain. T he difference betw een the dimensions
m ust not ex ceed 1/8 inc h (3 mm). If the
dimension ex ceeds 1/8 inc h (3 mm), re place
the blade because it is bent. Mak e sure to
measure all of the blades .
6. Compare the measurements of the outer blades
with the center blade . T he center blade m ust
not be more than 3/8 inc h (10 mm) lo w er
than the outer blades . If the center blade is
more than 3/8 inc h (10 mm) lo w er than the
outer blades , proceed to ste p 7 and add shims
betw een the spindle housing and the bottom
of the cutting unit.
7. R emo v e the bolts , flat w ashers , loc k w ashers ,
and n uts from the outer spindle in the area
where the shims m ust be added. T o raise or
lo w er the blade , add a shim, P ar t No . 3256-24,
betw een the spindle housing and the bottom
of the cutting unit. Contin ue to c hec k the
alignment of the blades and add shims until
the tips of the blades are within the required
dimension.
Important: Do not use mor e than
thr ee shims at an y one hole location. Use
decr easing n umber s of shims in adjacent
holes if mor e than one shim is added to
an y one hole location.
Correcting Cutting Unit
Mismatch
If there is mismatc h betw een the blades , on a
single cutting unit, the g rass will appear streak ed
when it is cut. T his problem can be cor rected b y
making sure that the blades are straight and all of
the blades are cutting on the same plane .
1. Using a 3 foot (1 meter) long car penters lev el,
find a lev el surface on the shop floor .
2. Raise the height-of-cut to the highest position;
refer to Adjusting the Height-Of-Cut.
