9.2. Side-to-side measurement: See Figure 9.2.
• Orient the outer pair of blades fore-and-aft.
• Check the vertical play on each element of the
blade assemblies to be measured. There will be
some up and down travel at the blade tips, gen-
erally between 1/8” and 1/4” (3.175mm and
6.35mm). If the amount of play significantly
exceeds this range, or is not consistent between
blade elements, identify the cause and correct it.
• Aerodynamic down-force overcomes the centrif-
ugal force that keeps the blades perpendicular to
the spindle axis at mowing speeds: the blades
operate at the lower end of the available play.
• Measure the distance to the ground from the left
and right rear blade tips. It should be equal.
9.3. If the distance from the left and right rear blade
tips to the ground is equal, proceed to fore-and-
aft pitch measurement. If the distance is not
equal, level the deck as described under the
Side-to-side leveling sub-heading.
9.4. Side-to-side leveling: See Figure 9.4.
• The right side deck lift link is fixed in length,
while the left side link is adjustable.
• Loosen the jam nut that locks the adjustment on
the left lift link using a 3/4” wrench.
• Move the adjustment nut up or down as neces-
sary to level the deck, using a 3/4” wrench.
• Tighten the jam nut, and double-check the level.
Readjust if necessary.
9.5. Fore-and-aft pitch measurement:
• Measure the distance to the ground from the
front and rear tips of the right side blade.
• The front blade tip should be between 1/8” and
1/4” (3.175mm and 6.35mm) closer to the
ground than the rear blade tip.
• This measurement should be the same for the
left side blade too. If it is not, identify and correct
the cause.
• If adjustment is necessary, proceed as
described in the deck pitch adjustment sub-
heading.
