Align Dimple Here
mounting pin. The mount pin can be installed in
two positions. For 60” decks, SN 599,999 and
lower, the pin should be installed as far away from
the bumper end as possible. For all 72” decks
and 60” and 66” decks SN 600,000 and higher,
the pin should be installed close to the bumper
end (See Figure 13).
FIGURE 13
28. Install the belt (Item 13) onto the blower by
working it around the impeller sheave.
FIGURE 14
All units:
29. Mount the blower on the deck by sliding the
mounting pin into the tube at the rear right corner
of the deck. Swing the blower closed. Adjust the
position of the front pin to engage the slot in the
front of the deck. Use the latch to lock the blower

not need to be removed. On 72” units the
cover has a hole, and the plastic knob must
be installed after the cover has been
positioned.
On Units SN 600,000 and Higher with Triton
decks:
32. Adjust dog leg baffle to match Ultra Vac
blower intake opening. Adjusting too wide
may allow objects to be thrown from under the
mower deck at high speed. Adjusting too
narrow may cause plugging issues.
WARNING
POTENTIAL HAZARD
♦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.
WHAT CAN HAPPEN
♦Thrown objects or blade contact can cause
serious injury or kill you or bystanders.
HOW TO AVOID THE HAZARD
♦Adjust dog leg baffle to match intake opening.
Assemble the Tubes
1. Slip upper and lower tubes together.
2. Insert upper tube into hopper seal – push in
then pull out so that seal is extended outward.
Align dimple on upper tube with end of hopper
seal and position vertically between the two
screws as shown in Figure 15.
FIGURE 15

Page 11 of 13
109-4195 Rev. A
3. Set deck in lowest cutting position.
4. Slide lower tube onto blower and latch (make sure
that upper tube does not move out of alignment).
5. Drill 7/32 holes in lower tube using upper tube holes
as reference. See Figure 16.
6. Remove tubes from unit and assemble the upper
(Item 2) and lower tubes (Item 3) using (3)
#10-24 x .75 hex washer head screws (Item 4), (3)
#10 washers (Item 6) , and (3) #10-24 nyloc nuts
(Item 5). Screw head should be installed to the
inside of the tube to provide minimum obstruction to
flow. Make sure that the upper and lower ends are
oriented properly as tubes are assembled. (Parting
lines roughly lined up.)
FIGURE 16
7. Slip the upper end of the tube assembly into the
hood opening. Slide the lower end of the tube
assembly over the blower outlet and align the notch

Install the Weight Plates
All units SN 599,999 and Lower and Liquid
Cooled XS units SN 600,000 and Higher only.
Weight plates not required for air cooled units
SN 600,000 and Higher.
1. The four weight plates (Item 33) must be installed
under the front panel of the floor pan. These
weights give proper balance to the machine when
the removable portions of the bagger are
removed.
Units below SN 600,000 with the 2 post foldable
ROPS installed require additional mounting plates
(Item 42) and a front weight (Item 41) to be
installed. The front weight is removable and
retained by using hairpins (Item 43).
Units SN 439,999 and Lower:
2. Locate the position of the mounting holes. Clamp a
weight plate to the front of the floor pan (See Figure
17). The ears on the weight plate should be
towards the bottom (upside down from the actual
mounted position). Align the bottom edge of the
weight plate with the bottom edge of the floor
pan front panel. Center the weight plate side to
side. Mark the position of all four holes using a
center punch.
3. Drill 3/8 inch holes at the points marked.

For units 439,999 and Lower without a ROPS
installed:
4. Install the four weight plates behind the front
panel using the 5/16-18 x 1.50 screws, 5/16
washers and 5/16-18 whizlock nuts (Items 34,
35, and 36). The weight plates will only fit
with the ears located near the bend in the floor
pan (See Figure 18). The decal on the
outside of the floor pan will still be visible with
the weight plates mounted.

For units SN 439,999 and Lower with a ROPS:
5. Install (4) weight plates behind the front panel and
(2) weight mounting plates (Items 33, and 39) as
shown in Figure 16 using (4) 5/16-18 x 2.0
screws, (4) 5/16 flat washers, and (4) 5/16-18
whizlock nuts (Items, 34, 35, and 36).
6. Hook weight plate assembly (Item 42) over the top
of the weight mounting plates and secure with two
hairpins (Item 43) as shown in Figure 19.

7. Locate the position of the mounting holes by
aligning the template (P/N 103-5865) on the front
face of the floor pan as shown in Figure 20.
Clamp the template in place. Using a center
punch, mark the positions of the holes on the floor
pan. Flip the template over and repeat on the
other end of the floor pan face.

For Lazer XS Liquid Cooled units SN 600,000
and Higher:
10. Locate the position of the mounting holes by
aligning the template (P/N 103-5865) on the front
face of the floor pan as shown in Figure 18.
Clamp the template in place. Using a center
punch, mark the positions of the holes on the floor
pan. Flip the template over and repeat on the

12. Install the four weight plates behind the front
panel using the 5/16-18 x 1.50 screws,
5/16 washers and 5/16-18 whizlock nuts
(Items 34, 35, and 36). The weight plates will
only fit with the ears located near the bend in

2. Install the removable weight assemblies over
the caster arms. On some 60” units one
weight has a wide mounting bracket and one
has a narrow bracket. They will only fit the
machine one way. Weights for all other units
are interchangeable left and right.
3. Install a clevis pin (Item 19) and hairpin (Item
20) on each caster weight to retain them.
4. Tighten knob on weight assembly until the
weight is clamped securely to the caster arm.

Operation
Pre-Start
1. Read the operator’s manual for the mower
and Ultra Vac to familiarize yourself with all
controls before operating the machine. Make
sure that you understand the controls, their
locations, their functions, and their safety
requirements.
2. Ensure the blower, belt cover, bags, tube and
hood are in good condition, properly attached,
and latched.
Run In
1. Verify that the blower drive operates correctly
prior to delivery to customer.
2. The Ultra Vac blower operates when deck
drive is engaged. Be sure that all persons are
clear of the mower deck and blower before
engaging the cutting blades. Set the throttle
to “midway” position. Pull outward on the
PTO switch to the “ROTATE” position.
3. 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.
