2. Ensure the blower, belt cover, bags, tube and hood are in good condition, properly
attached, and latched.
5.2 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 “idle” 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.
3. To remove the bags, 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 bags by inverting them.
4. Reinstall bags, close and latch the hood before continuing mowing.
5.3 BAGGER REMOVAL FOR SIDE DISCHARGE:
1. Shut off the deck drive, stop engine and wait for all moving parts to stop. Remove spark
plug wire(s) or remove key.
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 hood.
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.
