CAUTION

1.4 OPERATION

Although hazard control and accident prevention are partially dependent upon the
design and configuration of the equipment, t hese factors are also dependent upon the
awareness, concern, prudence, and proper training of the personnel i nvol ved in the
operation, transport, maintenance, and st orage of t he equi pment . It is essential that all
Operator Safety Mechanisms be connected and in operating condit i on prior to use for
mowing. Refer to the Operator’s Manual for the mow er f or addi tional hazard control
and accident prevention information.

POTENTIAL HAZARD
♦ An uncovered discharge opening will allow objects to

be thrown in operator’s or bystander’s direction. Also,

contact with blade could occur.
WHAT CAN HAPPEN
♦ Thrown objects or blade contact can cause serious

injury or kill you or bystanders.
HOW TO AVOID THE HAZARD
♦ Never operate mower unless discharge deflector,

entire grass collection system, or mulch kit is installed.

HOW TO AVOID THE HAZARD

1.4.1 Use EXTREME caution when mowing and/or turning on slopes as loss of traction and/or
tip-over could occur. The operator is responsible for safe operation on slopes.

POTENTIAL HAZARD

♦ There are rotating blades in the blower and under the

mower deck.

WHAT CAN HAPPEN

♦ Blade contact can cause serious operator or bystander

injury or even death.

♦ Do NOT reach into Blower unless Rotation Indicator

has Stopped. Disengage PTO, stop engine, remove
key, WAIT FOR MOVING PARTS TO STOP

♦

Never operate mower unless discharge deflector, entire
grass collection system, or mulch kit is installed.

WARNING

DANGER

POTENTIAL HAZARD
♦ Mowing on wet grass or steep slopes can cause

sliding and loss of control.

WHAT CAN HAPPEN
♦ Wheels dropping over edges, ditches, steep banks,

or water can cause rollovers, which may result in
serious injury, death or drowning.

HOW TO AVOID THE HAZARD

♦ Do not mow slopes when grass is wet.
♦ Do not mow near drop-offs or near water.
♦ Do not mow slopes greater than 15 degrees.
♦ Reduce speed and use extreme caution on slopes.
♦ Avoid sudden turns or rapid speed changes.

2

DANGER

• Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep
banks or water. This area can be dangerous, see Figure 1.

Figure 1

SAFE ZONE FOR MOWING

• Progressively greater care is needed as the slope increases.

• Always avoid sudden starting or stopping on a slope. If tires lose traction,

disengage the blades and proceed slowly off the slope.

• Avoid sudden starts when mowing uphill. Mower may tip backwards.

• Be aware that loss of traction may occur going downhill. Weight transfer to the

front wheels may cause drive wheels to slip and cause loss of braking and
steering.

• Watch for ditches, holes, rocks, dips, and r ises t hat change the operating angle,
as rough terrain could overturn the machine.

• Remove or mark obstacles such as rocks, t r ee lim bs, et c. from the mowing area.
Tall grass can hide obstacles.

• The operating characteristics of the machine will change with the Ultra Vac
installed. The stability and traction of the machine will change as the Ultra Vac
hopper fills with grass clippings. Use progressively greater care on slopes as the
hopper fills.

• Always install and remove the Ultra Vac, including counterweights, as inst r ucted.
Failure to do so will cause a reduction in stability or traction. Do not operate the
mower with only a portion of the Ultra Vac installed.

1.5 SAFETY SIGNS

1.5.1 Keep all safety signs legible. Remove all grease, dirt and debris from safety signs and
instructional labels.

1.5.2 Safety signs must be replaced if they are missing or illegible.

1.5.3 When new components are installed, be sur e t hat current safety signs are affixed to
the replaced components.

1.5.4 New safety signs may be obtained from your authorized Exmark equipment dealer or
distributor or from Exmar k Mfg. Co. Inc.

1.5.5 Safety signs may be affixed by peeling of f the backing to expose the adhesive
surface. Apply only to a clean, dry surface. Smooth to remove any air bubbles.

1.5.6 Familiarize yourself with the following safety signs and instruction labels. They are
critical to the safe operation of your Exmark Ultra Vac.

necessary lighting and marking as required by law. Secure a trailer with a safety
chain.

POTENTIAL HAZARD
♦ This unit does not have proper turn signals, lights, reflective

markings, or a slow moving vehicle emblem. These items
are required to drive on a public street or roadway.

WHAT CAN HAPPEN
♦ Driving on a street or roadway without such equipment is

dangerous and can lead to accidents causing personal injury.

♦ Driving on a street or roadway without such equipment may

also be a violation of State laws and the operator may be
subject to traff ic tickets and/or fines.

HOW TO AVOID THE HAZARD
♦ Do not drive a unit on a public street or roadway.

CAUTION

18

WARNING

POTENTIAL HAZARD
♦ Loading a unit on a trailer or truck increases the possibility of

backward tip-over.

WHAT CAN HAPPEN
♦ Backward tip-over of the unit could cause serious injury or

death.

HOW TO AVOID THE HAZARD

♦ Use extreme caution when operating a unit on a ramp.
♦ Use only a single, full width ramp; DO NO T use individual

ramps for each side of the unit .

♦ If individual ramps must be used, use enough ram ps t o

create an unbroken ramp surf ace wider than t he unit .

♦ DO NOT exceed a 15° angle between ramp and ground or

between ramp and trailer or truck.

♦ Avoid sudden acceleration while driving unit up a ramp to

avoid tipping backward.

♦ Avoid sudden deceleration while backing unit down a ramp to

avoid tipping backward.

4.4.2 Loading a Unit: Empty grass bags before attempting to load unit on trai l er or

Ramp should be long enough so that the angles between the ramp and the

truck. Use extreme caution when loading units on trailer s or trucks. One full
width ramp that is wide enough to extend beyond the rear tires is required
instead of individual ramps for each side of the unit. The lower rear section of
the tractor frame extends back between the rear wheels and serves as a stop for
tipping backward. Having a full width ramp provides a surface for the frame
members to contact if t he unit st arts to tip backward. If it is not possible t o use
one full width ramp, use enough individual ramps to simulate a full width
continuous ramp.

ground and the ramp and the trailer or truck do not exceed 15°. A steeper angle
may cause mower deck components to get caught as the unit moves from ramp
to trailer or truck. St eeper angles may also cause the unit to tip backward. If
loading on or near a slope, position the trailer or truck so it is on the down side of
the slope and the ramp extends up the slope. This will minimize the ramp angle.
The trailer or truck should be as level as possible.

DO NOT attempt to turn the unit while on the ramp, you may lose control and

drive off the side.

Avoid sudden acceleration when driving up a ramp and sudden decelerat ion when

backing down a ramp. Both maneuvers can cause the unit to tip back ward.

6. Tips and Troubleshooting

Your Exmark Ultra Vac has been designed to be the m ost pr oductive bagging system on the
market. The following tips have been collected to help you get the most out of your Ultra Vac
right from the star t .

6.1 When mowing in areas with sandy soil, use low lift blades on the cutting deck and
higher cutting heights t o minimize wear on the blower components.

6.2 When mowing in wet conditions, such as just af ter a rain or in heavy dew, use low
lift blades on the cutting deck to minimize plugging of t he blower.

6.3 When the bags g et full, the sound of the blower will change and there will be slight
blowout from the front right corner of the deck . Emptying the bags at this point will
minimize the potential for the tube to plug.

21

6.4 If there is excessive blowout from the deck, check t o make sure that the rear
screen in the hood is clear of grass build up. I t is recommended that the screen
and mesh portions of the bags be cleaned regularly to maintain proper air flow.
This is especially important in wet conditions.

6.5 During dry conditions check engine air cleaners and clean cooling f ins mor e
frequently. The Ultr a Vac has been designed to minimize the impact of dust and
debris on the mower, but bagging can be a dir t y environment.

6.6 During dry conditions, switching to a lower lift blade may reduce blowout without
hurting quality of cut.

6.7 Maintaining a ground speed that does not pull down the engine RPM will allow for
the highest productivity and best quality of cut . Bogging the engine RPM down by
going too fast will cause plugg ing and quality of cut issues.

6.8 When storing t he Ult r a Vac, it is recommended that any build up in the blower be
cleaned out. Dry grass build up may cause problems with the impeller when the
unit is put back into operation.

6.9 If the blower drive belt snaps or breaks frequently, check the alignment of the idler
arm per section 5. An arm that is bent out of position can cause the belt to jump
off of the idler and be cut by the sheaves.

6.10 If the idler pulley contacts the deck sheave, check the alignment of the idler arm
per section 5. Also check the mounting t ube on t he deck and the mounting pin on
the blower for bending or excessive wear. This condition is more lik ely to occur
with smaller deck sizes.

6.11 T he condit ion of the belt drive is critical to proper operat ion. A sticking idler arm or
worn belt may cause plugging or blowout. Replace the belt when the idler arm is
riding on or near the stop.
