Self-Adjusting
1. Remove inner parts box and handle from
crate. Remove outside frame work so
that the mower is setting on the pallet.
2. On a 36" mower, use 3 – 5/16" X 1 3/4"
bolts and 3 – 5/16" whizlocks and bolt the
bumper into place. (On the 48" there are
4 - bumper bolts required.)The whizlocks
should go to the inside of the deck.
When assembling a 48" mower, make
sure that the bumper is flush with the
deck on both ends of the bumper.
3. Using 6 – 3/8" X 1" bolts (3 – used for
each caster) and 6 – 3/8" whizlock nuts,
bolt the casters into place. Position
whizlock nuts to the inside of the deck.
4. Using 2 – 5/16" X 1" bolts with 2 – 5/16"
flat washers and 2 – 15/16" nyloc nuts,
take the shifter lever with grip and bolt
onto the top side of the shifter bracket on
the transmission. Place the 5/16" flat
washers on the slotted hole side of the
shifter bracket under the 5/16" nut.
Position the shift lever so that it slides
freely along the top side of the shifter
plate but still hits the stop for reverse.
5. Mount the gas tank using the 2 – nylon
hold down straps, pulling tension on the
buckles until secure. Attach the fuel supply
from the tank to fuel filter on the engine.
Attach vapor recovery line on engine to
the vent barb on the tank, Secure all connections
with hose clamps.
6. Using the remaining 4 - 3/8" X 1" bolts
and the 4 – 3/8" nyloc nuts, bolt the

7. Using drive rods provided, turn them into
the 5/16" swivel located in the left and
right hand idler engagement bracket.
Adjust the rods so that there is
approximately 1/4" to 3/8" between the
rod and the bottom of the thumb latch.
Rods should be locked in place by using
4 – hair pin cotters and by placing a 5/
16" flat washer to be inside of the drive
handle between the drive lever and hair
pin cotter. (See fig.2)
8. With the thumb latches locked in the
neutral position, adjust the brake swivel
until you feel a slight resistance when
hooking it back to the idler assembly.
Remember with thumb locks in the
neutral position, you should be able to
free wheel the machine. When the
thumb locks are rotated all the way to the
lock position, the brake should lock the
wheel. At this time, you may also hook
up the blade engagement rod, adjusting
the length of the rod so the bell crank will
not bottom out in the slot.
9. At this point, oil and fuel engine. Make
sure that the air pressures in the rear
tires are equal at (12 psi). Adjust the
front tire pressures to (20 psi). Your
mower is now ready for use.
Final Check / Adjustment
1. Adjust the brake control rod to obtain
“free wheeling” with the drive levers in
the neutral position and positive braking
when the drive levers are squeezed close
to the handle grips. Shorten the effective
length of the brake rod to increase
braking.
2. Check air pressure in drive wheels (12
psi) and caster wheels (20psi). This is
critical for appropriate mower tracking.
3. Check for proper belt tension (see belt
tension guide).
Keep a 1/8" to 1/4" clearance between
belt guides and belts. Be sure the drive
control rod is properly adjusted in the
thumb latch. (See Fig 2.)
3. After a 10 hour “Break-In” period go
through steps 1 thru 3.
4. Proper adjustments must be maintained
to insure safe, trouble free, long life
operation of the mower. After completing
the foregoing instructions and
recommended procedures you are ready
to put the mower into operation.
CAUTION:
Excessive belt tension may cause damage!!
