shaft to lower side, install the castor assembly and com-
pare blade height of all blades; refer to items 3 through 7.
Continue adding thrust washers if height still does not
meet requirements.
C. If the cutting unit is operated at 5–10 cm height-of-cut,
lower the high side of the cutting unit. Remove lynch pin
of the castor at high end of unit and remove the castor
assembly (Fig. 17).
D. Transfer one thrust washer from lower side of the castor
shaft to top side, install assembly and compare blade
height of all blades; refer to items 3 through 7. Repeat

pin, set the height-of-cut and resume operation.

REPLACING THE GRASS DEFLECTOR

1. Position the machine on a level surface, raise the cutting unit,
engage the parking brake, be sure the traction pedal is in neu-
tral position, the PTO lever in OFF position, shut engine OFF
and remove the key from the switch. Block the cutting unit to
prevent it from falling accidentally.
2. Remove two capscrews, locknuts and springs securing deflec-
tor mounts to pivot brackets.
3. To remove the pivot brackets, remove carriage bolts and nuts.
4. Reinstall pivot brackets on top of discharge opening with car-
riage bolts and nuts. Head of carriage bolts must be on inside
of the cutting unit.
5. Position deflector mounts on pivot brackets and secure parts
together with capscrews, locknuts and springs. Both locknuts
must face each other. Tighten the locknuts until they are flush
against deflector pivots.
6. Lift deflector and allow it to drop to check spring tension.
Deflector must be held firmly in full downward position by
spring tension. Correct if necessary.
