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, or entire grass collection
system, or mulch kit is installed.

3
DANGER
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.
HOW TO AVOID THE HAZARD
♦ 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.
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.
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.

• 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 rises that change the operating
angle, as rough terrain could overturn the machine.
• Remove or mark obstacles such as rocks, tree limbs, etc. 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 clippings. Use progressively 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 traction. Do
not operate the mower with only a portion of the Ultra Vac QDS 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 sure that current safety signs are
affixed to the replaced components.
1.5.4 Replacement safety signs may be obtained from your authorized Exmark
equipment dealer or distributor or from Exmark Mfg. Co. Inc.
1.5.5 Safety signs may be affixed by peeling off 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

WARNING
POTENTIAL HAZARD
♦ An uncovered opening can expose the
operator and bystanders to blade contact
and thrown debris.
WHAT CAN HAPPEN
♦ Blade contact or thrown debris can cause
serious injury or death.
HOW TO AVOID THE HAZARD
♦ Adjust dog leg baffle to match blower
intake opening.
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 components.
3.2 MOWING
3.2.1 The Ultra Vac QDS blower operates when deck drive is engaged. Be sure that all
persons are clear of the mower deck before engaging the cutting blades. Set
the throttle to “midway” position. Pull outward on the PTO switch to the
“ROTATE” position. Accelerate to full throttle to begin mowing.
3.2.2 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 to come 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
3.2.3 To empty the hopper, first shut off deck drive. Lift up on the handle to open the
door and empty the hopper. 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. See section 3.5 Transporting for additional
information regarding loading a unit on a truck or trailer.

3.5 TRANSPORTING
3.5.1 Transporting a Unit: Use a heavy-duty trailer or truck to transport the machine. Lock
brake and block wheels. Securely fasten the machine to the trailer or truck with
straps, chains, cable, or ropes. Be sure that the trailer or truck has all necessary
lighting and marking as required by law. Secure a trailer with a safety chain.
CAUTION
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 traffic tickets and/or fines.
HOW TO AVOID THE HAZARD
♦ Do not drive a unit on a public street or
roadway.

13
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
NOT use individual ramps for each side of
the unit.
♦ If individual ramps must be used, use
enough ramps to create an unbroken
ramp surface wider than the 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.
3.5.2 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 extreme caution when loading units 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 simulate a full width
continuous ramp.
Ramp should be long enough so that the 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. Steeper 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 backward.
Dump contents of hopper before transport . Do not transport the unit with the
hopper full.

14
4. MAINTENANCE:
WARNING
POTENTIAL HAZARD
♦ While maintenance or adjustments are
being made, someone could start the
engine.
WHAT CAN HAPPEN
