the 5/16” x 1” capscrews and flange locknuts. Install
each lever (grip inward) to the outside of each mount
angle with 5/16” x 1” capscrews, flatwashers and
flange locknuts. Adjust the levers so they are in line
with each other. Refer to picture below.
Battery

Additional wire tie straps are shipped to secure
wiring hardness as needed.
Items to Check:
Check oil level in the engine (see engine manual)

Check tightness of all fasteners, including bolts,
lug nuts, and setscrews.
Check tire pressure.
BASIC DECK ASSEMBLY
(Refer To Exploded Drawing On Next Page)
A. Remove the deck from the crating. Layout
hardware in the bolt bag.
B. Align the grass discharge shield with mounting
holes on the right side of the deck. Attach with
either two or three 3/8” x 1” capscrews and 3/8” lock-
nuts. Tighten these fasteners tight and back off 1/8
turn to allow the shield to float.
C. Attach the deck lift handle assembly to the
deck adjusting height plate with a 1/2” x 1-1/4” cap-
screw and locknut. Tighten fastener tight and back
off 1/8 turn to allow pivoting.
D. Attach the clevis end of the short rod assem-
bly to the deck mount with clevis spring pin. Align
the flattened end of the short rod assembly with the
mounting ears on the lift handle assembly. Install
the 3/8” x 1-1/8” linkage pin and one 1/8” cotter pin.
E. Install the last link of the four link chain to the
rear hanging brackets located on the back of the
deck. Secure with two 3/8” x 1” capscrews and lock-
nuts.
F. Position the lift arm weldment such that the u-
shaped cuffs extend between the ears on the pivot
tube and fasten with two 3/8” x 3” carriage bolts and
two locknuts. The carriage bolts should be posi-
tioned such that the bolts are installed from the bot-
tom and the nut is tightened on the top.
54” OR 60” DECK TORSION BAR
A. Attach the deck bracket with 3/8 x 1” cap-
screws, as shown below. Fasten the turnbuckle
between the deck bracket and the torsion bar lever.
With the deck in the fully raised, position, turn the
turnbuckle so as to extend its length. The more it is
extended, the more the torsion bar will be preloaded
and the easier the deck will be to raise. The maxi-
mum center to center length of the turnbuckle should
never exceed 6 inches.
BASIC DECK MOUNTING
A. With the foot plate raised, attach the PTO
driveline to the lower spline shaft of the power unit.
Move the mower deck to the front of the power unit.
Install the 3/16” x 1” key into the shaft of the gear-
box. Extend the driveline attaching the smooth yoke
to the shaft of the gearbox. Position end of yoke
approximately 1/4” from deck. Torque the two
setscrews to 31 ft./lbs.
B. Move the deck closer to the power unit being
careful not to over extend the power shaft. Align the
lower hole of the lift arm weldment with the slotted
hole in the power unit frame and pin with the two
1/2” x 2-1/4” clevis pin, flatwashers, and 1/8” x 1-1/2”
cotter pins.
C. Rotate the deck lift handle past the lowest
possible position and install the two deck locking
pins and cotter pin in the deck hanger brackets.
D. Rotate the deck lift handle back toward the
tractor and locate in the highest cutting position.
