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, belt cover, bags, tube and hood
are in good condition, properly attached, and latched.
For units above Serial Number 600,000 with Triton
decks: Make sure that the adjustable dog leg bafe 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 bafe 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 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 deck drive 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 remove the bags, rst shut off deck drive, stop
the engine and wait for all moving parts to stop.
Open the hood and remove the bags by lifting up
on the rear of the bag, then unhooking the front
clip. Empty the bags by inverting them.
4. Reinstall bags, close and latch hood before
continuing mowing.
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: Raise front adjustable bafe to
reduce plowing. Lowering front adjustable bafe
may prevent “chasing”. Match discharge opening
to Ultra Vac intake for best performance.
Bagger Removal for Side Discharge
1. Shut off the deck drive, stop engine and wait for
all moving parts to stop. Remove key and engage
parking brake.
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.
