Product Overview

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 Nos. 600,000 with Triton

decks: Make sure that the adjustable dog leg bafﬂe is

closed to match the intake into the Ultra Vac Blower.

5. Tube

WARNING

3. Weight

If the blower intake opening is not correct 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.

Operation

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.

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.

Figure 5

4. Hairpin

1. Hood

• 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.

2. Blower

3. Tube

5. Clevis Pin

6. Bag

3. Remove the belt cover by loosening the knobs

(see Figure 6).

• 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 SN 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.

the discharge tube assembly by slipping the upper

end into the hood, then sliding the lower end over

the blower discharge opening. Use the latches to

retain the lower end to the blower.

WARNING

Loading a unit on a trailer or truck increases

the possibility of backward tip-over.

Backward tip-over could cause serious injury

or death.

8. For Units 600,000 and Higher with Triton

Decks: Adjust position of dog leg bafﬂe to match

the intake of the Ultra Vac blower bafﬂe adjusted

too wide may allow objects to be thrown from

under deck. Bafﬂe adjusted too narrow may cause

plugging issues.

• Use extreme caution when operating a

unit on a ramp.

• Use only a single, full width ramp; Do

Not use individual ramps for each side

of the unit.

For units with a 2 post ROPS installed: Install

the weight.

• If individual ramps must be used, use

enough ramps to create an unbroken

ramp surface wider than the unit.

Note: The portions of the Ultra Vac bagger that

are not bolted to the mower are designed to be

installed or removed in their entirety. Do Not

operate the mower with only a portion of the

Ultra Vac installed.

• Do Not exceed a 15° angle between ramp

and ground or between ramp and trailer

or truck.

• Avoid sudden acceleration while driving

unit up a ramp to avoid tipping backward.

Transporting

• Avoid sudden deceleration while backing

unit down a ramp to avoid tipping

backward.

Transporting a Unit

Use a heavy-duty trailer or truck to transport the

machine. Lock brake and block wheels. Securely

fasten the machine to the trailer or truck with straps,

chains, cable, or ropes. Be sure that the trailer or truck

has all necessary lighting and marking as required by

law. Secure a trailer with a safety chain.

Loading a Unit

Empty grass bags before attempting to load

unit on trailer or truck. Use extreme caution when

loading units on trailers or trucks. One full width

ramp that is wide enough to extend beyond the rear

tires is recommended instead of individual ramps for

each side of the unit. The lower rear section of the

tractor frame extends back between the rear wheels

and serves as a stop for tipping backward. Having

a full width ramp provides a surface for the frame

members to contact if the unit starts to tip backward.

If it is not possible to use one full width ramp, use

enough individual ramps to simulate a full width

continuous ramp.

CAUTION

This unit does not have proper turn

signals, lights, reﬂective markings, or a

slow moving vehicle emblem. Driving on a

street or roadway without such equipment

is dangerous and can lead to accidents

causing personal injury. Driving on a street

or roadway without such equipment may also

be a violation of State laws and the operator

may be subject to trafﬁc tickets and/or ﬁnes.

Ramp should be long enough so that the angles

between the ramp and the ground and the ramp and

the trailer or truck do not exceed 15°. A steeper angle

may cause mower deck components to get caught as

the unit moves from ramp to trailer or truck. Steeper

angles may also cause the unit to tip backward. If

loading on or near a slope, position the trailer or

truck so it is on the down side of the slope and the

ramp extends up the slope. This will minimize the

Operation

ramp angle. The trailer or truck should be as level

as possible.

Important: Do Not attempt to turn the unit

while on the ramp, you may lose control and

drive off the side.

Avoid sudden acceleration when driving up a ramp

and sudden deceleration when backing down a ramp.

Both maneuvers can cause the unit to tip backward.

Maintenance

Note: Determine the left and right sides of the machine from the normal operating position.

WARNING

While maintenance or adjustments are being

made, someone could start the engine.

Accidental starting of the engine could

seriously injure you or other bystanders.

The engine can become very hot. Touching

a hot engine can cause severe burns.

Allow the engine to cool completely before

service or making repairs around the engine

area.

Remove the key from the ignition switch,

engage parking brake, and pull the wire(s)
