3. Check the right and left rear Drive tire pressure.
Adjust as necessary to 8-10 psi.
4. Measure blade-to-ground height at the front tip
of the right blade. To obtain an accurate mea-
sure, align blades in parallel with mower center-
line, (i.e. front to back).
5. Measure blade-to-ground height at the front tip
of the left blade. Be sure to measure at the
blade tip with the blades arranged in proper
position.
6. To level the deck, (side to side) adjust the
threaded link at the left side of the deck (Point B)
so that the blade-to-ground height at the right
front blade tip matches that of the left front blade
tip. This is done by loosening the jam nuts on
the threaded link and tightening the lower nut to
raise the deck and loosening the nut to lower the
deck.
7. Measure the blade-to-ground height at the right
rear blade tip. Again be sure to measure at the
blade tip at the rear of the right blade when
aligned along the mower centerline. The blade-
to-ground height at the rear of the blade tip
should be 1/8" to 1/4” higher than the front tip.
This is referred to as blade pitch. The same
height difference should be true for the left
blade, measured front and back.
8. To adjust the blade pitch, the deck pitch must be
adjusted. Loosen the inner jam nuts at the rear
of the horizontal threaded links. Start at Point C
to raise the rear of the deck, tighten the front
outer jam nut to raise the front of the deck.
Adjust the rear jam nut at Point C to take the
slack out of the threaded link.
9. The final adjustment would be to take the “slack”
out of the front linkage (Point C) by adjusting the
jam nuts on the threaded link. Loosen the jam
nuts and tighten the inner nut to remove “slack”.
10. In many cases it will be necessary to adjust
deck height using both eyebolt adjustments and
pitch adjustment to achieve the correct blade-to-
ground heights. If you remember that the front
right blade tip adjustment is fixed and you level
to that height, adjusting the decks will be simpli-
fied.
