Cab Surface
1. DECK SOUND BARRIER
Mounting surface preparation: adhesivebacked sound barrier should be applied to a
clean, dry surface at room temperature. Although the mounting surface may appear
clean, it is required that the surface be cleaned with isopropyl alcohol or an acetone or
ammonia-based cleaner immediately prior
to application of the sound barrier material.
Allow cleaned surfaces to dry thoroughly.
Good surface contact is required to achieve
bond. Failure to follow these steps can result
in the separation of the sound barrier material from the mounting surfaces.
NOTE: paint thinners or products with any
oil in them will not work and are detrimental
to the proper cleaning of the underside of the
fender. NOTE: clean rags are very important. Oily rags will leave residue.
1.1 Remove the ROPS (Roll Over Protection Structure)
structure, the operator seat, the control lever handles, the
differential lock, forward - reverse and brake pedals
from the mower. Remove the operator deck by removing
the two bolts at the back of the deck and the four nuts (2
each side) from the frame supports under the left and
right foot wells. Open the hood, lift the deck up off of the
front mounting studs, tip the back of the deck up and
move to the rear lifting off of the park brake lever and
the steering column cover. Reference Kubota mower
service manual for a more detailed description.
1.2 Remove the grab handle from the left side by removing the two (2) hex nut/washer combinations (SEMS)
from underneath the fender. Discard hardware and handle. See fig. 1.2.
1.3 Position the operator deck upside down on a soft
table to prevent scratching. Remove all 10 plastic pine
tree clips (5/side) that hold the floor mats in place. Discard these 10 small, short plastic clips. 16 larger, longer
plastic pine tree clips are provided in the hardware bag
along with 16 fender washers (1/4” I.D.).
1.4 Note: dry fitting the pieces to get a feel for location
is suggested before peeling back the protective paper.
Place the main piece of sound barrier on a flat table with
the adhesive side up. Cut the center rear section of the
adhesive backing paper 15” from the rear edge as shown
in fig. 1.4.
1.5 Position the main piece of the deck sound barrier in
place as shown in fig. 1.5. Lift up one section at a time,
peel the adhesive backing paper off and adhere the sound
barrier to the deck. DO NOT remove 15” of backing
paper of rear center section that was cut in step 1.4.
1.6 Position the left and right pieces of sound barrier as
shown in fig. 1.6, peel the adhesive backing paper off
and adhere to the deck as shown.

1. DECK SOUND BARRIER (cont’d.)
Use of the supplied plastic pine tree clips and
fender washers (qty.: 16 of ea.) is strongly
advised to help secure the sound material
around the bends in the fender and will help
prevent the sound material from prematurely coming loose. See figures 1.7.1, 1.7.2, and
1.7.3.
1.7 Before re-installing the floor mats, use the 5 existing
holes per fender side as guides to drill 9/32” diameter
holes through the newly installed sound material. Also
drill 3 new holes (9/32” diameter) per side as shown in
figure 1.7.3. Approximate locations are sufficient as
shown. Install 8 plastic pine tree clips per side as shown
with the thin head side up top and the fender washers
below the deck surface sandwiching the sound material
lightly (not shown). Note: no need to over-compress the
sound material with the fender washers.
1.8 Reinstall the deck, pedals, ROPS, and operator seat.
IMPORTANT: the bolts on the ROPS structure must
be torqued properly to meet original equipment safety standards. These four (4) bolts (M14 diameter) are
to be torqued to 91-108 ft.-lbs. (124-147 N-m).
DO NOT install the nuts on the front foot well mounting
studs that were removed in step 1.1, but retain them for
later use. Tuck the slit in the center rear section around
the knob and make sure to pull the seat switch wire up
through the cutout before securing the deck.
1.9 The small piece of sound barrier from the kit can be
stuffed in place under the access door for the transmission filler cap. Do not adhere it to the door. Remove this
piece when checking transmission fluid. See figure 1.9.

2.2 Have one 10mm x 1.25 x 20mm long hex head
bolt ready. Remove one of the two large clamping
hand knobs from the middle of the upright of the roll
bar while holding the “U” shaped bracket in place. See
figures 2.2 and 2.2.1. Install the new hex head bolt
through the hole in the “U” shaped bracket and tighten
in place. Note: washers are not used here. Repeat for
opposite side. Discard the hand knobs.
