3.4.7 Remove the plastic belt cover. Pull the spring loaded idler back and slip the belt
over the top spindle deck sheave.
3.4.8 Install the plastic belt cover. The rear of the cover is slotted and can slip behind
the plastic knob on the belt shield stud. The plastic knob does not need to be
removed. The front horizontal plastic knob for the plastic belt cover must be
installed after the cover has been positioned.
The front vertical plastic knob on the original steel belt cover can be used
for plastic belt cover.
3.4.9 The hopper inlet has ribs to engage the spiral reinforcement of the flexible tube.
Using a marker or paint pen, mark the flexible tube approximately 4" from the
end. Insert the end of the tube into the hopper inlet, and rotate clockwise to
engage. Rotate and thread the tube into the hopper inlet up to the 4" mark. It may
be easier to "push" the tube into the inlet rather than rotating. (See Figure 6.)
3.4.10 Slide the lower end of the tube assembly onto the blower outlet adapter and
rotate to lock in place. Install the lock pin through the tube and blower adapter.
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.
