Important: T he cur v ed par t of the blade
must be pointing up w ard to w ard the inside
of the mo w er to ensur e pr oper cutting .
2. Install the cur v ed w asher (cupped side to w ard
the blade) and blade bolt ( Figure 40 ). T or que
the blade bolt to 35-65 ft-lb (47-88 N·m).
Leveling the Mower from
Side-to-Side
T he mo w er blades m ust be lev el from side to side .
Chec k the side-to-side lev el any time y ou install
the mo w er or when y ou see an unev en cut on y our
la wn.
1. P osition the mo w er on a flat surface .
Diseng ag e the PTO , set the parking brak e , stop
the engine , and remo v e the k ey . Disconnect
the spark plug wire(s) from the spark plug(s).
2. Chec k the air pressure of all four tires . If
needed, adjust to the recommended inflation;
refer to Tire Press .
3. Set the height-of-cut at 3 inc h (76 mm).
4. Carefully rotate the blade(s) from side to side
( Figure 43 ). Measure betw een the outside
cutting edg es and the flat surface ( Figure 43 ).
If both measurements are not within 3/16 inc h
(4.75 mm), an adjustment is required; refer to
ste ps 5 and 6.

5. R emo v e the hair pin cotter and w asher from
the lev eling brac k et ( Figure 44 ). T o lev el the
blade(s), re position the lev eling brac k et(s) in
a different hole and install the w asher and
hair pin cotter . ( Figure 44 ). A front hole lo w ers
the blade height and a rear hole raises its
height. Adjust both sides as required.

6. Chec k the front-to-rear blade slope; refer to
Adjusting the F ront-to-R ear Blade Slope .
Adjusting the Front-to-Rear
Blade Slope
Chec k the front-to-rear blade lev el any time y ou
install the mo w er . If the front of the mo w er is
more than 5/16 inc h (7.9 mm) lo w er than the
rear of the mo w er , adjust the blade lev el using the
follo wing instr uctions:
1. P osition the mo w er on a flat surface .
2. Diseng ag e the PTO and mo v e the control
lev ers to the neutral loc k ed position and apply
the parking brak e .
3. Stop the engine , remo v e the k ey , and w ait for
all mo ving par ts to stop before lea ving the
operating position.
4. Chec k the air pressure of all four tires . If
needed, adjust to the recommended inflation;
refer to Tire Pressure .
5. Chec k and adjust the side-to-side blade lev el
if y ou ha v e not c hec k ed the setting; refer to
Lev eling the Mo w er from Side-to-Side .
6. Measure the length of the rear tr union rod
( Figure 45 ). If the rod length is not 11-1/2 inc h
(29.2 cm), remo v e the clevis pin and cotter
pin from the end of the rod ( Figure 45 ),
loosen the jam n ut, and tur n the y ok e until the
11-1/2 inc h (29.3 cm) dimension is obtained.
