4.3.6. ADJUSTING MOWER BLADE
The straightness of the mower blade(s) is essential for
smooth, even mowing. Adjust blade straightness as
follows. NOTE: Follow Steps 1 thru 4 for all deck
sizes.
1. Make sure fuel cap is on tight. Turn fuel shut off
valve (If equipped) to the “CLOSED” position. Start
engine and allow it to run until engine runs out of
fuel. Close vent on fuel filler cap. See Figure 2.3, Page
6.
2. Remove key from ignition switch.
3. Remove spark plug wire(s) and secure away from
spark plug(s).
4. Carefully stand YARD CRUISER on rear bumper.
(Adjusting the 33” Deck Blade)
5. Select a point on the deck and mark for
reference.
6. Mark blade tips as “A” and “B”.
7. Rotate blade until blade tip “A” is at deck
reference mark.
8. Measure the distance between deck lip and
blade tip. NOTE: On 33” decks, the measurement
between the blade tip and deck lip should be 3/8”.
See Figure 4.5.
9. Repeat step 8 with blade tip “B”.
10. If measurement between blade tips and deck
are different and there is more than 1/16” difference
between blade tip measurements, adjust blade as
follows:
a. Loosen jam-nuts on the ends of blade bar.
b. Adjust jack screws “IN” or “OUT” until blade
tip measurements are within 1/16” of each other
and blade tips are 3/8” away from deck lip. See
Figure 4.6.
c. Retighten jam-nuts securely.

cutting edges and deck. See Figure 4.7.
FIGURE 4.7
14. Rotate blade until blade cutting edges “B” are
together. See Figure 4.8.

between either set of blade tips, one or both blades
are bent and must be replaced with new blades.
