GRASS BAGGING
Ariens recommends grass cutting with grass bagger
without vanes before installing vanes for increased per
formance. If performance is satisfactory without vanes
(available for mowers of 32" cutting width or less), do
not use vanes. The vanes use more power and generate
more noise. Use vanes only if satisfactory performance
cannot be obtained without them. Generally, broadleaf
grasses can be cut and bagged without vanes. The
finer grasses may require the use of vanes. In extremely
wet conditions, vanes may also be of help.

• TIGHTEN DETENT SCREWS THROUGH
HOLES TO HOLD SHIFT LEVER IN GEAR .
FIGURE 4
DISK BRAKE ADJUSTMENT - FIGURE 5
Once each season, or if the brake begins to slip and
does not hold the tractor, it is necessary to adjust the
disk brake located on the lower left side of the transaxle
assembly. See Figure 5. Adjust as follows:
1. Position the tractor on a smooth level surface and
place the speed selector lever in “NEUTRAL" so
the tractor can be pushed by hand to check the
brake.
2. Adjust the setscrew in the brake jaw assembly
clockwise until the brake just starts to lock. This
can be felt by pushing the tractor by hand. Leave
the brake pedal up during this adjustment.
The tension on the brake pedal itself is adjustable. If the
brake pedal does not return or feels loose, adjust the
nut on the end of the brake rod just inside the frame
next to the parking brake slot. Tighten the nut until the
spring adjacent to the nuts is 1 % inches in length.
FRONT WHEEL TOE-IN ADJUSTMENT - FIGURE 6
Proper toe-in of the front wheel is necessary to assure
proper steering and to reduce tire wear. Correct toe-in
is when the front of the wheels are Vs" to Vi" closer
together than the rear of the wheels (measured at the
horizontal center line of the rim flanges).
If the steering develops a wandering characteristic or if
excessive tire wear develops, the toe-in of the front
wheels should be checked. If the toe-in is not correct,
adjust as follows;
1. Turn steering wheel until the rear edge of the
steering pivot is perpendicular (90 degrees) to the
tractor frame as shown in Figure 6.
2. Adjust length of tie rods until distances from
steering arm to frame (A and B) are equal and so
distance C is between Vs" to Vi" less than
distance D.
NOTE: USE FOLLOWING PROCEDURE TO SHORTEN
OR LENGTHEN TIE RODS.
1. Loosen jam nuts on ends of tie rods. Figure 6.
2. Remove the locknuts and pull out the ball joints.
Rotate tie rods until distances A and B, Figure 6,
are equal and distance C is Vs" to Vi" less than D.
3. Tighten jam nuts securely. Replace ball joints in
holes and secure with locknuts.
