To make front-to-rear adjustment
NOTICE: Always level the deck side-to-side before making a front-
to-rear adjustment.
1. Position both blades so that the ends point toward the front
and back of the mower (Fig. 24a).
2. Measure the distance from the tip of one blade to the ground
(see Fig. 24b). For best results, the front tip of the blade should
be from 5/64 in to 25/64 in (2 mm to 10 mm) lower than the
rear tip.
3. If front-to-rear adjustment is needed, use a 23/32 in (18 mm)
open-end wrench or adjustable wrench (not supplied) to adjust
the four nuts on the suspension linkage (two for each side)
(Fig. 24c).
NOTICE: Make sure to turn the corresponding nuts on both sides
equally to avoid altering the side-to-side measurement.
4. Measure again to verify that the front tip is now 5/64 in to
25/64 in (2 mm to 10 mm) lower than the rear tip. If not,
continue to adjust and measure until they are.
5. Retighten the nuts. The recommended torque for the nuts is
38-42 ft-lb (52-57 N.m).
