Front to Rear Deck Leveling
1. Place the mower on a hard surface that is clean
and level.
2. Set the cutting height to a high setting to allow
access to the mower blades. All points must be
at the same cutting height.
3. If the deck is equipped with pneumatic tires, ensure
that all the tires are inflated to the same pressure.
Center Deck
4. Turn the mower blades so the blade tips are at
the rear of the deck and measure the distance
between the blade tip and the surface the deck
is setting on.
5. Rotate the mower blades so the same tip is at
the front of the deck and measure again. The
blade tip should be level to 1/8” (3.2 mm) low at
the front.
6.
If the distance is greater than 1/8” (3.2 mm), the
center deck must be leveled. To begin adjust-
ments, loosen the 4) 1/2” bolts that fasten the
front of the center deck to the carrier frame.
7. Raise or lower the front of the deck until the front of
the deck has been leveled relative to the rear of the
deck for both the left and right sides of the deck.
8.
Retighten the 4) 1/2” bolts. Torque to 75 ft-lbs
(102 Nm).
Left Deck
9. Verify that the rear roller is level with the surface
that the deck is setting on. If the roller is not level
(if either the right or left end of the roller is raised
off the ground), the front and rear connecting
links require adjustment.
a.
If the outboard side of the roller is raised off
the measuring surface, the links must be
shortened. Loosen the jam nuts, unbolt the
rod ends from the center deck, and turn the
rod ends in two turns. Reattach rod ends to
center deck. Repeat until the rear roller is
level with the measuring surface, reattach
rod ends to the center deck, and tighten the
jam nuts.
b.
If the inboard side of the roller is raised off
the measuring surface, the links must be
lengthened. Loosen the jam nuts, unbolt the
rod ends from the center deck, and turn the
rod ends out two turns. Reattach rod ends
to center deck. Repeat until the rear roller is
level with the measuring surface, reattach
rod ends to the center deck, and tighten the
jam nuts.
10. Turn the mower blades so the blade tips are at
the rear of the deck and measure the distance
between the blade tip and the surface the deck
is setting on.
11. Rotate the mower blades so the same tip is at the
front of the deck and measure again. The blade tip
should be level to 1/8” (3.2 mm) low at the front.
12.
If the distance is greater than 1/8” (3.2 mm), the
deck must be leveled. To begin adjustments,
loosen the 4) 3/8” bolts that fasten the front yoke
anchor plate to the front of the center deck.
13. For the inboard blade, raise or lower the front
yoke anchor plate until the inboard blade is level
to 1/8” (3.2 mm) low at the front.
14.
Retighten the 4) 3/8” bolts. Torque to 31 ft-lbs
(42 Nm).
15.
For the outboard blade, Loosen the 1/2” bolt that
holds the tire swivel frame to the deck.
16.
Add 1/2” USS flat washers beneath the caster
wheel frame to raise the outboard front of the
deck. Remove existing washers to lower the
outboard front of the deck.
17.
When the deck is level, torque the 1/2” bolt to
75 ft-lbs (102 Nm).
Right Deck
18. Verify that the rear roller is level with the surface
that the deck is setting on. If the roller is not level
(if either the right or left end of the roller is raised
off the ground), the front and rear connecting links
require adjustment.
a.
If the outboard side of the roller is raised off
the measuring surface, the links must be
lengthened. Loosen the jam nuts, unbolt the
rod ends from the center deck, and turn the
rod ends out two turns. Reattach rod ends
to center deck. Repeat until the rear roller is
level with the measuring surface, reattach
rod ends to the center deck, and tighten the
jam nuts.
b.
If the inboard side of the roller is raised off
the measuring surface, the links must be
shortened. Loosen the jam nuts, unbolt the
rod ends from the center deck, and turn the
rod ends in two turns. Reattach rod ends to
center deck. Repeat until the rear roller is
level with the measuring surface, reattach
rod ends to the center deck, and tighten the
jam nuts.
19. Turn the mower blades so the blade tips are at
the rear of the deck and measure the distance
between the blade tip and the surface the deck
is setting on.
