This is a CRT(counter-rotatingtine) tiller
and its tines must be mounted in the
direction shown in Figure 5-7. If
mounted with the curves in the opposite
direction, the tiller will dig poorlyand be
more likely to run backward.
Failure to comply could result in per*
sonal injuryor propertydamage.
NOTE:If the nuts are rusted, apply pene-
trating oil to the bolt and nut. Let the oil
soak in for a few minutes before loosen-
ing the nut. Always loosen the nut rather
than the bolt.
2. When installing individual tines, install
them in the reverse order from which
they were removed. The two sets of
inboard tines are installed so one tine
faces toward the transmission housing
and the other Onefaces away from it.
The single outboard tine on each side
faces toward the transmission housing.
Also be sure the cutting edges face so
they will enter the soil first when the tiller
is moving forward- this means the
cutting edges face toward the operator

CHECKING AND ADJUSTING
TENSION ON DRIVE BELTS
Follow the belt adjustment instructions
carefully. An incorrectadjustment could
result in the ForwardClutch mechanism
engaging too soon. This could cause
loss of tiller control and result in per-
sonal injuryor propertydamage.
Maintaining correct tension on the drive
belts is important to good tilling perfor-
mance and long belt life. A loose belt will
slip on the engine and transmission
pulleys and cause the tines and wheels to
slow down - or stop completely - even
though the engine is running at full
speed.A loose belt will also result in pre-
mature wear to the belt.
While checking belt tension, also check
for cracks, cuts or frayed edges. A belt
that is in poor condition should be
replaced.
The tension on a new forward drive belt
should be checked after the first two (2)
hours of operation. Thereafter, check the
tension after every ten (10) hours of
operation.
The reverse drive belt, because it is used
more sparingly, will probably not require
an initial tension adjustment until a sig-
nificant number of operating hours has
passed.
To Checkand AdjustTension
on the ForwardDrive Belt:
1. Checkingfor correct belt tension is the
same as that described in item 5, Step 4:
Attach Forward Clutch Rod. Before
checking, shut off the engine, disconnect
the spark plug wire, and allow the engine
and muffler to cool down. If, after follow-
ing the adjustment procedures, you
cannot get the correct gap on the forward
clutch rod adjustment bracket, you will
need to make a secondary adjustment as
described next.
2. Disconnect the Forward Clutch Rod (A,
Figure5-9) from the swivel plate (B) by
removing the innermost hairpin cotter
(C).
3. Unthread the Forward Clutch Rod (in a
counterclockwise direction as viewed
from the front of the unit) until one or
two threads on the rod extend abovethe
rectangular nut (D, Figure 5-10) on the
forward clutch bracket.
4. Removethe belt cover.
5. Slip the forward drive belt (E, Figure
5-9) off the engine-driven forward drive
pulley by pushing it off (away from
engine) with your left hand while pulling
engine starter rope with your right hand.
6. On the left side of the unit (from oper-
ator's position) remove the hairpin cotter
from the clevis pin (F, Figure5-I I) that
connects the forward idler arm (G) to the
forward adjustable link (H). Push inward
on the forward idler arm (G) and remove
the clevis pin (F).
7. Thereare two holes in the forward
adjustable link (H, Figure 5-11). Push
inward on the forward idler arm (G) and
install the clevis pin (F) through the inner
hole in the forward adjustable link (H)
and out through the single hole in the
forward idler arm (G). Secure the clevis
pin with the hairpin cotter.
