3. To empty the hopper, first disengage the PTO.
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 Ultra Vac 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 Ultra Vac at this point will minimize
the potential for the tube to plug.
Collection System Removal for Side
Discharge
1. Empty the hopper.
CAUTION
The hopper assembly is heavy when it is full,
which may make it difficult to remove the
hopper assembly from the unit. The entire
hopper assembly may fall, which may cause
injury.
Prior to removing the hopper assembly from
the unit, first empty the contents.
2. Disengage the PTO, stop engine, wait for all
moving parts to stop, and remove key. Engage
parking brake.
3. 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 hopper.
