4.5 CHECK MOWER BLADE
See Figures 5 and 6.
Regularly check mower blades for wear and that lock
washer is fully compressed by cap screw (requires
25-30 ft-lbs (33-40 Nm) of torque on cap screw).
When blade needs sharpening:
1. Block blade to prevent rotation.
2. Remove cap screw, lock washer and blade from
shaft.
3. Sharpen both ends of blade at original angle (25
removing equal amounts of material from each end
to maintain proper blade balance. New blades are
balanced to within 1.3 in. oz. at factory. DO NOT
grind around corner at tip of blade. If cutting edge
of blade cannot be sharpened in a straight line to
within 1/8 of an inch of its end, replace blade with
Ariens replacement blade only.
4. Install blade, lock washer and tighten cap screw
25-30 ft-lbs (33-40 Nm) until lock washer is fully
compressed.
IMPORTANT: If mower is used under sandy soil
conditions, replace blades when air lifts become
eroded.

4.7 CHECK ENGINE/BLADE CONTROL
The engine/blade control must stop the engine and
blade within 3 seconds after the bail is released. If the
engine or blade continues to run, adjust or repair
control immediately.
Engine control must stop engine ignition, at 3/4" to
1-1/4" from handlebar as control is released.
4 - 23
Page 24
To check (Figure 7):
1. Start engine and slowly release control until engine
stops firing.
2. Measure distance between handlebar and control
at the point that engine stopped firing.
3. Turn cable nuts at handlebar mount clockwise if
measurement is more than 1-1/4" or counterclockwise if measurement is less than 3/4".
4. Turn nuts against mount to lock in position.

4.9 CHECK DRIVE CONTROL
Check operation of drive control. The drive must
disengage completely when the bail handle is
released. Adjust bail travel if necessary. See Figure 10.
When the wheel drive control is squeezed toward the
handlebar, the extension spring, located at the bottom
end of the traction cable, must start to extend when the
control is between 1-1/2" and 2" (3.8 and 5 cm) away
from the handlebar. To check:
1. Squeeze the wheel drive control toward the
handlebar until the spring starts to open.
2. Measure the distance between the wheel drive
control and handlebar at the handlebar indentation.
3. To obtain the proper adjustment, turn the cable
nuts. Turn clockwise if the measurement is more
than 2"; counterclockwise if the measurement is
less than 1-1/2". Tighten the nuts against the
bracket to lock in position. If there is not enough
thread length for adjustment, the opposite end of
the cable can be adjusted.
Three Speed Drive Control
When the wheel drive control bail is squeezed toward
the handlebar, the extension spring must start to
extend when the control bail is between 3-7/8" to 4-1/8"
away from the handlebar. The extension spring is
located at the bottom end of the traction control cable.

4.10 HANDLEBAR ADJUSTMENT
Holes in handlebar braces provide four height
positions, a service position, and a storage position
(except on profession al mod els ).
Use one of the four holes to adjust handlebar height to
a safe, comfortable position. Place bolt on handlebar
bracket through one of holes 1, 2, 3 or 4 in order of
increasing height (See Figure 11).
NOTE:
On Professional models nuts and bolts replace
pins.
For storage, rotate handlebar forward and place pins
through holes further up braces.
4.11 SPEED CONTROL BELL CRANK
The speed control bell crank holds the speed selector
rod in position after a speed has been set. The spring
washers may become loose with normal wear. If the
speed selector rod does not stay firmly in position,
adjust the speed control bell crank. See Figure 12.
To adjust:
1. Remove cover, fu lly compress the helical spring
lockwashers with lock nut and then back lock nut
off, one half turn.
2. If the speed selector rod is still too loose, tighten
lock nut by small increments until it holds its
position. Tightening the lock nut too much will not
allow the speed selector rod to move at all.
3. Align notch in left hand side of cover with bolt and
secure with knob.
