Safety  
Slope Operation  
DANGER  
Use Extreme caution when mowing and/or turning  
on slopes as loss of traction and/or tip-over could  
occur. The operator is responsible for safe operation  
on slopes.  
There are rotating blades in the blower and  
under the mower deck. Blade contact can  
cause serious operator or bystander injury  
or even death.  
• Do Not reach into blower unless rotation  
indicator has stopped. Disengage PTO,  
stop engine, remove key, wait for all  
moving parts to stop. engage parking  
brake.  
DANGER  
Operating on wet grass or steep slopes can  
cause sliding and loss of control. Wheels  
dropping over edges, ditches, steep banks, or  
water can cause rollovers, which may result  
in serious injury, death or drowning.  
• Never operate mower unless discharge  
deflector, entire grass collection system,  
or mulch kit is installed.  
• Do Not mow slopes when grass is wet.  
• Do Not mow near drop-offs or near water.  
• Stop engine, wait for all moving parts to stop,  
remove key and engage parking brake:  
• Do Not mow slopes greater than 15  
degrees.  
– Before checking, cleaning or working on the  
mower.  
• Reduce speed and use extreme caution  
on slopes.  
– After striking a foreign object or abnormal  
vibration occurs (inspect the mower for  
damage and make repairs before restarting  
and operating the mower).  
• Avoid sudden turns or rapid speed  
changes.  
• See inside the back cover to determine the  
approximate slope angle of the area to be mowed.  
– Before clearing blockages.  
– Whenever you leave the mower.  
• Use a walk behind mower and/or a hand trimmer  
near drop-offs, ditches, steep banks or water.  
(Figure 3).  
WARNING  
Hands, feet, hair, clothing, or accessories can  
become entangled in rotating parts. Contact  
with the rotating parts can cause traumatic  
amputation or severe lacerations.

Safety  
• Remove or mark obstacles such as rocks, tree  
limbs, etc. from the mowing area. Tall grass can  
hide obstacles.  
• Watch for ditches, holes, rocks, dips and rises that  
change the operating angle, as rough terrain could  
overturn the machine.  
• Avoid sudden starts when mowing uphill because  
the mower may tip backwards.  
• Be aware that loss of traction may occur going  
downhill. Weight transfer to the front wheels  
may cause drive wheels to slip and cause loss of  
braking and steering.  
• Always avoid sudden starting or stopping on a  
slope. If tires lose traction, disengage the blades  
and proceed slowly off the slope.  
• Follow the manufacturer’s recommendations for  
wheel weights or counter weights to improve  
stability. Always install and remove the Ultra Vac,  
including counter weights, as instructed. Failure  
to do so will cause a reduction in stability or  
traction. Do Not operate the mower with only a  
portion of the Ultra Vac installed.  
• Use extreme care with grass catchers or  
attachments. These can change the stability of the  
machine and cause loss of control. The stability  
and traction of the machine will change as the  
Ultra Vac hopper fills with grass clippings. Use  
progressively greater care on slopes as the hopper  
fills.  
Maintenance and Storage  
• Disengage drives, set parking brake, stop engine  
and remove key or disconnect spark plug wire.  
Wait for all movement to stop before adjusting,  
cleaning or repairing.  
• Use care when checking blades. Wrap the blade(s)  
or wear gloves, and use caution when servicing  
them. Only replace blades. Never straighten or  
weld them.  
• Keep all guards, shields and all safety devices in  
place and in safe working condition.  
• Check all bolts frequently to maintain proper  
tightness.  
• Frequently check for worn or deteriorating  
components that could create a hazard.  
• All replacement parts must be the same as  
or equivalent to the parts supplied as original  
equipment.

Operation  
on the deck. Verify that all rotation indicators  
have stopped before clearing blower assembly or  
mower deck  
Operation  
Note: Determine the left and right sides of the  
machine from the normal operating position.  
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.  
Pre-Start  
Make sure you understand the controls, their  
locations, their functions, and their safety  
requirements.  
4. Reinstall bags, close and latch hood before  
continuing mowing.  
Ensure the blower, belt cover, bags, tube and hood  
are in good condition, properly attached, and latched.  
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.  
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.  
• 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.  
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.  
• 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.  
Adjust dog leg baffle to match intake  
opening.  
Refer to the Maintenance section and perform all the  
necessary inspection and maintenance steps.  
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.  
Operating Instructions  
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.  
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.  
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. 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  
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.

Both maneuvers can cause the unit to tip backward.  
• 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.  
• If individual ramps must be used, use  
enough ramps to create an unbroken  
ramp surface wider than the unit.  
• 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.  
• Avoid sudden deceleration while backing  
unit down a ramp to avoid tipping  
backward.  
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.  
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
