side bumper bars to the vertical "HOT" engine
guard shield using two of the original screws,

guard plate ("HOT" engine guard on liquid cooled
units) to the rear frame of the Lazer Z unit.
10. Install the mount weldment (Item 9) loosely to the
rear of the machine using the two bolts and nuts
removed in Step 8.

CAUTION
POTENTIAL HAZARD
♦
Relying solely on mechanical or hydraulic
jacks to support the mower could be
dangerous.
WHAT CAN HAPPEN
♦
The mechanical or hydraulic jacks may not be
enough support or may malfunction allowing
the unit to fall, which could cause injury.
HOW TO AVOID THE HAZARD
♦
DO NOT rely solely on mechanical or
hydraulic jacks for support. Use adequate jack
stands or equivalent support.
12. Install the right and left hand frame brackets
(Items 14 and 15) loosely to the mount
weldment and wheel channels on both sides
of the Lazer Z frame. The flanges on the side
plates should face in towards the unit to
provide the maximum tire clearance.

13. Secure using (8) 3/8-16 x 1.00 bolts (Item 23),
(8) 3/8 spring disk washers (Item 25) and (8)
3/8-16 whizlock nuts (Item 24). Make sure
that the raised portion of the spring disk
washer faces the head of the bolt.
NOTE: On units with a ROPS installed, the
lower front screw that attaches to the wheel
motor channel must be left uninstalled. Units
with Serial Numbers 440,000 through 509,999
will have a captured bolt in this position. See
Figure 4.
NOTE: On 60" units, the lower bolt on the
wheel channel is best installed by positioning
the nut behind the hole using a deep socket
and turning the bolt through the hole into the
nut.
