Operation

Operation
Note: Determine the left and right sides of the
machine from the normal operating position.

Pre-Start

Make sure you understand the controls, their
locations, their functions, and their safety
requirements.
Ensure the blower, door mesh, tube and hopper are
in good condition, properly attached, and latched.
For units above Serial Number 600,000 with Triton
or Series 5 decks: Make sure that the adjustable dog
leg baffle is closed to match the intake into the Ultra
Vac Blower.
WARNING
If the deck discharge opening and the blower
intake opening do not match correctly, it will
allow objects to be thrown in operator's or
bystander's direction. Also, contact with blade
could occur. Thrown objects or blade contact
can cause serious injury or kill you or bystanders.
Adjust dog leg baffle to match intake opening.
Refer to the Maintenance section and perform all the
necessary inspection and maintenance steps.

Operating Instructions

Mowing
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.
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. 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 the Transporting section for
additional information regarding loading a unit
on a truck or trailer.
4. Close and latch the door before continuing
mowing. Do Not engage the cutting blades while
the door is in the open position.
Tips for mowing conditions:
• 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.
• 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 the blower.
• 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
plugging and quality of cut issues.
• 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.
• For units below Serial Number 600,000:
Anti-blowout kits are available for leaf collection.
They help to prevent "chasing" the leaves. To
reduce "plowing" leaves, raise the deck slightly.
• On Triton and Series 5 Decks: Raise front
adjustable baffle to reduce plowing. Lowering
front adjustable baffle may prevent "chasing".
Match discharge opening to Ultra Vac intake for
best performance.
Collection System Removal for Side
Discharge
1. Shut off the deck drive, stop engine and wait for
all moving parts to stop. Remove key.
2. Remove the discharge tube by releasing the latches
at the blower. Slide the tube off the blower outlet
and remove the upper end from the hood.
