OOI SERIES
TILLER has R.H. and L.H. tines. Check both tines
periodically for loose or missing fasteners. Replace
tine assembly when blades are badly worn or dam¬
aged. Use SNAPPER #4-9735 R.H. and #4-9734
L.H. tines with #1-5676 shear bolts and #9-0222
locknuts for replacement purposes.
The tines are bolted securely to the tine shaft with a
special shear bolt (SNAPPER #1-5676) and locknut
(#9-0222) on each side. Keep spares on hand in case
a bolt shears off or becomes lost while tilling. See
Figure 10. NOTE: Do not over-tighten shear bolts as
this will cause failure. Tighten 5 to 8 foot pounds of
torque maximum !
BELT ADJUSTMENT- REPLACEMENT
BELT TENSION ADJUSTMENT: To chpck, remove
LH. wheel and drive belt guard. Measure the length
of the IDLER PULLEY SPRING at the end of the con¬
trol cable. Move the WHEEL & TINE CONTROL up to
the handle bar and measure the extended length of
the spring. When properly adjusted, the spring
should extend 1/4" to 1/2" when WHEEL & TINE
CONTROL is engaged. If adjustment is required,
loosen and reposition the jam-nuts on the threaded
ends of the cable conduits. To increase spring ex¬
tension, turn the jam-nuts closer to the cable fittings.
See Figure 11.
BELT ADJUSTMENT TEST: start engine and pull
WHEEL & TINE CONTROL to handle bar then release
ana observe tines and wheel drive which should stop.
If tines or wheels continue after WHEEL & TINE
CONTROL is released, the clutch spring extension
is too great. Readjust using the foregoing procedure.
