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 t he 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 connect ed and i n operat i ng condi t ion prior
to use for mowing. Refer to the Operator’s Manual for the mower for additional
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 chute or

entire grass collection system 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 r esponsible 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

♦

Do NOT operate mower without deflector chute or
entire bag system in place.

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.

DANGER

2

• 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 overtur n 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
QDS installed. The stability and traction of the machine will change as the
Ultra Vac QDS hopper fills with grass clipping s. Use pr ogressively greater
care on slopes as the hopper fills.

• Always install and remove the Ultra Vac QDS, including counterweights, as
instructed. Failure to do so will cause a reduction in stability or tr act ion. Do
not operate the mower with only a portion of the Ultra Vac Q DS inst alled.

1.4 SAFETY SIGNS

1.4.1 Keep all safety signs legible. Rem ove all g r ease, dirt and debris from saf et y
signs and instructional labels.

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

1.4.3 When new components ar e inst alled, be sur e that current safety signs are
affixed to the replaced components.

1.4.4 Replacement safety signs may be obtained from your authorized Exmark
equipment dealer or distributor or from Exmark Mfg. Co. Inc.

1.4.5 Safety signs may be affixed by peeling off the backing t o expose the adhesive
surface. Apply only to a clean, dry surface. Smooth to remove any air bubbles.

1.4.6 Familiarize yourself with the following safet y signs and instruction labels. They
are critical to the safe operation of your Exmark Ultra Vac QDS.

3.7 ADJUSTMENTS:

Your Ultra Vac QDS was adjusted at the factory to operate properly. However, there are

three basic adjustments that can be made, should your unit r equire them:

3.7.1 Door closi ng: The closing of the door is controlled by the two hinge links (Figure
13 – A) and the two stop screws (Figure 13 – B). The stop screws should be
adjusted so that both will be contacted when the contacting arm is straight up and
down. With the stop scr ews adjusted, t he length of the hinge links can be
changed to provide complete closing of t he door , and reasonable force on the
handle to latch or unlatch the door. Lengthen the links to reduce the for c e.
Shorten the links to increase the force. With the door closed, both links should be
slightly tight to minimize rattling.

3.7.2 Door openi ng: After adjusting the hinge links for door closing, the handle link
(Figure 13 – C) can be adjusted to obtain m aximum door opening. Lengthen the
link to open the door fart her . Shorten the link to open the door less. The
maximum door opening is limited by the contacting ar m hitting the stop (Figure 13
– D). This stop is non adjustable, and prevents over opening dam age from
occurring to the linkage.

3.7.3 Latches: Once the open and closed positions have been set, the latches (Figur e 13
– E) can be adjusted. With the door closed, the latch link should be set so that the
latch plate completely engages and contacts the latch rod welded to the door. The
latch plates should not be tight against the latch rod. They should easily “wiggle”.

FIGURE 13

4. OPERATION:

4.1 PRE-START

4.1.1 Read the operator’s manual for your mower and fam iliar ize yourself with all
controls before operating t he machine. Make sure that you understand the
controls, their locations, their functions, and their safety requirements.

4.1.2 Ensure the blower, belt cover, door m esh, tube and hopper are in good condition,
properly attached, and latched.

Note: When mowing in areas with sandy soil, use low lift blades on the cutting
deck and higher cutting heights to minimize wear on the blower component s.

4.2 MOWING

4.2.1 The Ult r a Vac QDS blower operates when deck drive is engaged. Be sure that all
persons are clear of the mower deck bef ore engagi ng t he cutting blades. Set
the throttle to “midway” position. Pull out ward on the PTO switch to the
“ROTATE” position. Accelerate to full throttle to begin mowing.

4.2.2 To disengage the PTO and blower, set the throttle to “midway” position. Push in
on the PTO switch to the “STOP” position to stop the cutting blades and blower.
The cutting blades will require a slightly longer amount of time t o com e to a
complete stop when the blower is installed on the deck. Verify that all rotation
indicators have stopped before clearing blower assembly or mower deck

4.2.3 To em pt y the hopper , first shut off deck drive. Lift up on the handle to open the
door and empty the hopper. If the unit i s t o be dri ven onto a truck or t r ai ler

with the hopper full, always back the unit up the ramp. This will reduce the
chance of rearward tip up. See secti on 4. 1 Transporti ng f or addi t ional
information regarding loading a unit on a truck or t r ai l er.

4.2.4 Close and latch t he door before continuing mowing. Do not engage the cutt ing
blades while the door is in the open position.

4.3 BAGGER REMOVAL FOR SIDE DISCHARGE:

4.3.1 Disengage the PTO, stop engine and wait f or all moving parts to stop. Remove
spark plug wire(s) or remove key.

4.3.2 Remove the discharge tube by releasing the latch at the blower. Slide the tube
off the blower outlet and remove the upper end from the hopper.

4.3.3 Remove the Belt cover by loosening t he knobs. For 60” units the outboard knob
does not need to be removed completely to remove the belt cover.

4.3.9 Remove the hair pins and clevis pins holding the hopper assembly to t he m ount
weldment.

4.3.10 Lift the hopper assembly off the mount.

4.3.11 The removable weights must be removed from above the caster wheels (and front
of floor pan for unit s with a 2 post foldable ROPS). To remove the caster weight s.
Loosen the clamping knobs until the weight can be m oved relative to t he cast er
arm. Remove the hairpins and clevis pins that hold the weights to the cast er
arms. Carefully lift the weights off of the caster arms.

For units with 2 post foldable ROPS: To remove the front weight , r emove the 2

hairpins that retain it and then lift it from the m ount plates.

The weights and brackets bolted to t he floor pan remain on the unit.

Note: The removable weights are heavy. Use care when lifti ng t hem. M ake sure t hat

you can hold them securely before lifting them. Use caution w hen posi t i oning
your hands so that you do not set them down on your hands or fingers.

Note: The portions of the Ultra Vac QDS bagger that are not bol t ed t o t he mower

are designed to be installed or removed in their entirety. 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 QDS installed.

CAUTION

POTENTIAL HAZARD
♦ Caster or front floor pan weights installed without

bagger may cause Loss of Tract ion and St eer ing

control.
WHAT CAN HAPPEN
♦ Loss of control can result in an accident, which may

cause Death, Injury, or property damag e.
HOW TO AVOID THE HAZARD
♦ Install caster and front floor pan weights ONLY when

bagger is installed.

4.3.12 The machine can now be used for side discharge mowing.

4.4 TRANSPORTING

4.4.1 Transporting a Unit: Use a heavy-duty trailer or truck to tr anspor t t he machine. Lock
brake and block wheels. Securely fasten the machine to the trailer or truck with
straps, chains, cable, or ropes. Be sure t hat t he trailer or truck has all 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.

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.

CAUTION

WARNING

4.4.2 Loading a Unit: If the unit is to be driven onto a truck or trailer with the

hopper full, always back the unit up the ramp. This will reduce the chance
of rearward tip up. Use extrem e caut ion when loading unit s on trailers 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 the unit starts to tip backward. If it is not possible to
use one full width ramp, you must use enough individual ramps to simu lat e a full
width continuous ramp.

19

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

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 deceleration when

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

Dump contents of hopper before transport. Do not transport the unit with the

hopper full.

5. MAINTENANCE

POTENTIAL HAZARD
♦ While maintenance or adjustments are being made,

someone could start the engine.
WHAT CAN HAPPEN
♦ Accidental starting of the engine could seriously injure

you or other bystanders.
HOW TO AVOID THE HAZARD

5.2 ADJUSTMENTS

Your Ultra Vac QDS was adjusted at the fact or y to oper at e pr operly. However, there are
three basic adjustments that can be made, should your unit r equire them:

5.2.1 Door closing: The closing of the door is controlled by the two hinge links (Figur e
15 – A) and the two stop screws (Figure 15 – B). The stop screws should be
adjusted so that both will be contacted when the contacting arm is straight up and

5.2.2 Door opening: After adjusting the hinge links for door closing, the handle link
(Figure 15 – C) can be adjusted to obtain m aximum door opening. Lengthen the
link to open the door fart her . Shorten the link to open the door less. The
maximum door opening is limited by the contacting ar m hitting the stop (Figure 15

latch plate completely engages and contacts the latch rod welded to the door. The
latch plates should not be tight against the latch rod. They should easily “wiggle”.

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 after 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 get 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.

6.4 If there is excessive blowout from the deck, check to 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 fins more
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 stor ing the Ultra 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 The condition of the belt drive is critical t o proper operation. A sticking idler ar m or
worn belt may cause plugging or blowout. Replace the belt when the idler arm is
riding on or near the stop.

Owner’s Responsibilities

The Exmark turf equipment, including any defective part,
must be returned to an authorized Exmark service dealer
within the warranty period. This warranty extends only to

maintenance, whether performed by a dealer or by you, is
at your expense.

As a condition to this warranty, customer shall have read
the operator's manual and shall have completed and
submitted to Exmark Warranty Company, within the
prescribed time, the Exmark warranty registration.

General Conditions

The sole liability of Exmark and Exmark Warranty Company
with respect to this warranty shall be repair and replacement
as set forth herein. Neither Exmark nor Exmark Warran ty

or damage, including but not limited to, any incidental
or consequential loss or damage.

In particular, we shall have no liability or responsibility for:

• Expenses related to gasoline, oil or lubricants.

• Travel time, overtime, after hours time or other

extraordinary repair charges or charge relating to
repairs or replacements outside of normal business

There are no understandings, agreements, representations,
or warranties, express or implied, including but not limited to
any regarding the merchantability (that product is fit for
ordinary use) or fitness for use (that product is fit for a
particular purpose), not specified herein, respecting the
equipment which is the subject of this warranty.

Some states do not allow exclusions of incidental or
consequential damages, or limitations on how long an
implied warranty lasts, so the above exclusions and
limitations may not apply to you.

This warranty gives you specific legal rights, and you may
also have other rights which vary from state to state.
