1. Dimple
4. Set the deck in the lowest cutting position.

latches. (Make sure that the upper tube does not
move out of alignment).
Use the chart below as a guide for the approximate
overlap between the upper and lower tubes.
Deck Size

6. Drill three 7/32 inch holes in the lower tube using
the upper tube holes as reference.
7. Remove tubes from the unit and assemble the upper
and the lower tubes using three #10-24 x 3/4 inch
hex washer head screws, three #10 washers, and
three #10-24 nyloc nuts. The screw head should
be installed to the inside of the tube to provide
minimum obstruction to flow. Make sure that the
upper and the lower ends are oriented properly as the
tubes are assembled. (Parting lines should roughly
be lined up.)

Adjusting the Blower Drive Belt
Position
1. Read the operator's manual for the UltraVac and
mower before performing this adjustment. Make
sure that you understand the controls, their locations
their functions and safety requirements.
2. Ensure the blower, belt cover, bags, tube and hood
are in good condition, properly attached and latched.
3. Run the unit with the PTO and the blower engaged
for two minutes.
4. Disengage the PTO, stop the engine and remove
the key.
5. Remove the belt cover and check to make sure that
the belt is riding near the center of the flat idler on
the idler arm. If the belt is not riding near the center
of the idler, remove the blower, and bend the idler
arm slightly.
6. Reinstall the blower and belt cover and perform
steps 3-5 again to verify belt position.

install the ROPS pin assembly.
