4. OPERATION:

4.1 PRE-START

4.1.1 Read the operator's manual for your mower and familiarize yourself with all
controls before operating the machine. Make sure that you understand the
controls, their locations, their functions, and their safety requirements.
4.1.2 Ensure the blower, belt cover, door mesh, tube and hopper are in good condition,
properly attached, and latched.
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.

4.2 MOWING

4.2.1 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.
4.2.2 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
4.2.3 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 4.1 Transporting for additional
information regarding loading a unit on a truck or trailer.
4.2.4 Close and latch the door before continuing mowing. Do not engage the cutting
blades while the door is in the open position.

4.3 BAGGER REMOVAL FOR SIDE DISCHARGE:

4.3.1 Disengage the PTO, stop engine and wait for all moving parts to stop. Remove
spark plug wire(s) or remove key.
4.3.2 Remove the discharge tube by releasing the latch at the blower. Slide the tube
off the blower outlet and remove the upper end from the hopper.
4.3.3 Remove the Belt cover by loosening the knobs. For 60" units the outboard knob
does not need to be removed completely to remove the belt cover.
