Exmark Ultravac Bagger 126-8680 Operator's Manual page 10

Operation
• Stop the blades, slow down, and use caution
when crossing surfaces other than grass and when
transporting the mower to and from the area to
be mowed.
• Be aware of the mower discharge path and direct
discharge away from others. Avoid discharging
material against a wall or obstruction as the
material may ricochet back toward the operator.
Stop the blades, slow down, and use caution
when crossing surfaces other than grass and when
transporting the mower to and from the area to
be mowed.
WARNING
Hands, feet, hair, clothing, or accessories can
become entangled in rotating parts. Contact
with the rotating parts can cause traumatic
amputation or severe lacerations.
• Do Not operate the machine without
guards, shields, and safety devices in place
and working properly.
• Keep hands, feet, hair, jewelry, or clothing
away from rotating parts.
• Park machine on level ground. Stop engine, wait
for all moving parts to stop, remove key and
engage parking brake:
– Before checking, cleaning or working on the
mower.
– After striking a foreign object or abnormal
vibration occurs (inspect the mower for
damage and make repairs before restarting
and operating the mower).
– Before clearing blockages.
– Whenever you leave the mower.
• Tragic accidents can occur if the operator is not
alert to the presence of children. Children are
often attracted to the machine and the mowing
activity. Never assume that children will remain
where you last saw them.
– Keep children out of the mowing area and
under the watchful care of another responsible
adult, not the operator.
– Be alert and turn the machine off if children
enter the area.
– Before and while backing or changing
direction, look behind, down, and side-to-side
for small children.
– Never allow children to operate the machine.
– Do Not carry children, even with the blades
shut off. Children could fall off and be
seriously injured or interfere with the safe
operation of the machine. Children that have
been given rides in the past could suddenly
appear in the working area for another ride and
be run over or backed over by the machine.
Mowing
1. The UltraVac blower operates when the PTO is
engaged. Be sure that all persons are clear of the
mower deck before engaging the cutting blades.
To engage the PTO, pull the switch outward to
engage the cutting blades and blower.
2. Disengage the PTO by pushing 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, first disengage the PTO, stop
the engine and wait for all moving parts to stop.
Open the hopper 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 hopper 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 UltraVac gets full, the sound of
the blower will change and there will be slight
blowout from the front right corner of the deck.
Emptying the UltraVac at this point will minimize
the potential for the tube to plug.
