10. Install the mounting pin weldment (Item 8) to the
blower assembly using the 3/8-16 x .75 bolts (Item
15) and whizlock nuts (Item 24). Maximum deck
clearance will be provided if the bolts are installed
from below the mounting pin. There are (2) different
mounting pin weldments, install as shown. (See
Figure 12).

11. Install the belt (Item 7) onto the blower by working it
around the impeller sheave.
12. 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 in
this position. Adjust the tension on the latch to hold
the blower up to the deck, yet allow for release by
hand.
13. Pull the spring loaded idler back and slip the belt
over the top deck spindle sheave.
14. Install the plastic belt cover (Item 5). The rear of the
cover is slotted and can slip between the knob and
deck reinforcement plate. The knob retaining the
front of the original steel belt cover must be reused
and installed after the new plastic cover has been
positioned.
Assemble the Tube
1. 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 13.)

1. Orient hose adapter flange on tube with hose
adapter flange on blower housing (it only goes
on one way). Engage shoulder bolts through
keyholes in adapter flange on blower and rotate
to lock. Insert lock pin in small hole in top of
flange to lock in place. See Figure 14.

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, flexible tube and
hopper assembly 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"
