Operation

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 baffle 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 baffle 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, first 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 baffle to reduce plowing. Lowering front adjustable baffle 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.
