Tiller Tines; Belt Replacement - Snapper RT5 Series Service Manual

TILLER TINES
The tines are bolted securely to the tine shaft with a
special shear bolt (Snapper #1-4586) and locknut
(9-0289) on each side. Keep spares on hand in case a
bolt shears off or becomes lost while tilling.
The Snapper Tines are sharpened on front and rear
edge for forward or reverse rotation. The point of the
tines should be the leading edge under all condi¬
tions except when used in the forward mode for
cultivating (Refer to TINE SELECTION for details).
BELT ADJUSTMENT & REPLACEMENT
BELT TENSION ADJUSTMENT:
Stand tiller on end
and swing belt cover up to provide access to belt
and idler. Pull clutch control to handle bar and
observe where idler arm is positioned under the tiller
frame. With the belt tight, the idler arm should be ap¬
proximately parallel to the cross member. If at an
angle, adjust idler at driven pulley by loosening
capscrew and shifting position of idler until arm is
pulled parallel.. The spring should be extended 5".
Retighten capscrew on idler after adjustment.

OFF-SEASON STORAGE
Thoroughly clean all external surfaces and tines
before storing the Tiller. The Tiller may be stored on
end, however, the following steps must be taken.
BELT REPLACEMENT:
To replace the belt, stand
tiller on end, swing belt cover up to provide access
to belt and idler, move shift lever between position R
and 1. Remove capscrew, washer and lockwasher
from the V idler under frame then slide idler down
bolt to allow slipping belt on and off the pulley.
Remove belt by slipping off pulleys and pull out of
the frame. To install replacement belt, thread belt
thru opening in back of frame, route belt around
engine pulley, idlers and belt guide then slide V idler
back and secure with the fasteners removed earlier.
Use care to insure that belt is kept straight over tiller
pulley and idler and in desired tilling mode. Readjust
belt tension as required.
DRIVEN DISC SERVICE
If the wheels loose traction, stand the tiller on end
and check the rubber driven disc. Poor traction
could be caused by an excessively worn driven disc
or by improper positioning of the disc. If the rubber
disc appears in good condition, shift the transmis¬
sion into reverse then into #1 forward position. In
both settings, the rubber disc should be located out¬
side of the indentation in the center of the metal
drive disc. If the rubber disc rides on the edge of in¬
dentation in either setting, loosen the screws
holding the shift detent to the frame then tilt the de¬
tent until the rubber disc is outside the edge of the
indentation. Securely tighten the detent screws. The
disc should be about equal distance from the outer
edge of the indentation in both reverse and #1 posi¬
tions when properly adjusted.
Replace the driven disc if worn unevenly or if worn
down to the point where it no longer makes firm con¬
tact with the drive disc. To replace, remove the three
flange nuts, slip the old disc off the hub then install
the replacement and secure with the three flange
nuts.
1. Drain gasoline from fuel system and drain the
engine crankcase oil (refer to engine manual for
details).
2. After standing the Tiller on end, check the plugs in
the chain case for leakage. After extended period,
some grease may seep thru upper bearing races.
3. At the start of the new season, replenish engine
crankcase oil and add gasoline to the fuel tank after
returning the Tiller to its wheels.
4. Before starting, move the ENGINE CONTROL to
OFF and pull rope starter slowly several times. If ex¬
cessive resistance is felt, remove the spark plug and
pull rope starter rapidly to spin the engine and clear
oil from the cylinder. Clean and reinstall the spark
plug before attempting to start the engine.
