TILLER TINES
TfNE SERVICE: The SNAPPER IRT4 Series
2 TILLER has R.H. and L.H. tines. Check both tines
periodically for loose or missing fasteners. Replace the
assembly when blades are badly worn or damaged.
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 check, remove
L.H. wheel and drive belt guard. Measure the length
of the IDLER PULLEY SPRING at the end of the control
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 extension, 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 and 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.
