3. ASSEMBLY INSTRUCTIONS

3.1 UNCRATE MOWER

3.2 INSTALL DRIVE WHEELS

3.2.1 Mount drive wheels with the valve stem to the outside of the unit. Secure using
four (4) 1/2-20 x 7/8" UNF wheel bolts (installed in hubs) or 1/2-20 wheel nuts
(installed on studs in hubs) for each wheel. Torque to 95 ft-lbs (128 N M).
NOTE: Earlier models require the UNF wheel bolts. Later models have studs
installed in the wheel hub and require wheel nuts.

3.3 CHECK TIRE PRESSURE.

3.3.1 Check tire pressure in caster and drive tires. Proper inflation pressure for all four
(4) tires is 13 psi (90 kPa). Adjust if necessary.

3.4 INSTALL SEAT RETAINING ROD (Standard Seat) or SEAT (Suspension Seat)

3.4.1 For all units with a standard seat: Tilt seat up. Remove 5/16" nyloc nut from bolt
attaching seat retaining rod to seat frame. Remove ignition keys attached to bolt.
Remove retaining rod from seat and insert the "L" shaped end of the rod into the
hole directly above the left-side hydraulic pump mounting hardware (the "L" must
be positioned to the right). Position the seat retaining rod to the outside of the
mounting tab on the seat frame and secure with 5/16"x 1" bolt and nut. Tighten
until snug, then loosen just enough so the rod pivots freely.
For all units with a suspension seat: The seat base
frame with adjustable tracks and seat retaining rod
are already attached to the unit. Remove the
suspension seat from front of crate and discard
the hardware. Position the seat with the front set
of holes on the studs in the adjustable tracks; be
sure the left and right tracks are aligned (See
Fig.1). Loosen the vinyl curtain frame at the rear
by pushing down and ahead out of the hole.
Secure the seat with four 5/16 whizlock nuts.
Reattach the vinyl curtain frame. Connect the
terminal at the end of the wire tied to the seat
frame to the switch in the bottom of the seat.
