4. Loosen the jam nuts on bolts (A), and turn the bolts to
rotate the cam to the desired position. Viewed from the
right side, rotate the cam clockwise to obtain more
aggressive tine action.
NOTE:
The factory setting at forward adjuster bolt should be
12 mm (15/32 in.) lower than at rear adjuster bolt. If tine
aggressiveness has changed, then the adjuster bolt offset
may not equal factory settings. Always measure the
adjuster bolt offset and maintain throughout the vertical
adjustment.
