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
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
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.
