service with engine and blade running. STOP

secure away from spark plug. Engine and

3. Slide driven disc assembly over to 1/8” from
outside edge of drive disc. Maintaining the 1/8”
measurement, remove any misalignment from the
transfer rod linkage and the driven disc assembly
anchor point. This can be done by loosening nut and
rotating the transfer rod ball joint clockwise on the
transfer rod until alignment with the driven disc
assembly anchor point is achieved. Retighten ball
joint nut. Insert ball joint into anchor point and reinstall
the connector hex nut and tighten securely. See
Figure 4.8. Move ground speed control to the first
speed position, then back to the sixth speed position.
Recheck the 1/8” measurement described previously.
Reinstall driven disc spring to driven disc assembly.
