7. Re-install the deck drive belt in the lower groove of the double sheave.
8. Remove the discharge chute from the deck. Discard the mounting hardware, but
save the discharge chute for use during side discharge operation. The chute pivot
pin (Item 21) and hairpin (Item 22) may be stored in the pivot holes on the discharge
chute during bagging operation.
52 inch units only (60 and 72 inch units skip to step 17)
9. Remove the belt guide on the blower (see Figure3)
10. Install the belt (Item 13) included in the completing kit onto the blower assembly as shown.
11. Reinstall the belt guide removed in step 9.
12. If the Ultra Vac is being installed on a Lazer Z with a serial number less than 260,000, it is
recommended to replace the steel blocker plate mounted across the bottom of the blower
with the small filler plate (Item 26) included in the completing kit. Use the hardware that
was removed when removing the large blocker plate. Failure to install a blocker plate
will create a thrown object hazard that could injure or kill bystanders, or cause
property damage. This modification should not be done if the Ultra Vac blower will be
mounted on a Lazer Z with a serial number of 260,000 or higher.
13. The front right deck stiffener must be trimmed for belt clearance on 52" Lazer Z units.
Measure and mark the deck stiffener per Figure 4. Trim off the indicated portion of the
stiffener. Touch up the trimmed area with Exmark red touchup paint – P/N 1-850337.
