Deck Lift Rod Timing Adjustment - Ferris 5900631 Operator's Manual

DECK LIFT ROD TIMING
ADJUSTMENT
1. Park machine on a flat, level surface. Disengage
the PTO, stop the engine, and engage the parking
brake. Make sure that all of the tires are properly
inflated.
2. Place a level (A, Figure 24) on top of the cutting
height indicator (E) and adjust the cutting
height indicator up or down with the deck height
adjustment handle (B) until the cutting height
indicator is level.
3. Loosen, but do not remove the height indication
plate hardware (C) that secures the height
indicator plate (D). Manuever the height indicator
plate up or down until the cutting height indicator
points to the 3.25" (8,26 cm) mark. Tighten the
height indication plate hardware.
4. Refer to Figure 25. To check the deck lift rod
timing, measure and record the distance between
the lift pivots and the rod pivots. Repeat for the
other side of unit.
5. If the measurements for the rods and pivots are
equal, no further adjustment is required. If the
measurements are NOT equal (greater than 1/8"
(3,17 mm) difference), adjustment is required,
continue with Step 6.
6. Block up the mower deck until all hanger chains
are slack.
7. Refer to Figure 26. To adjust the lift rods the
1/2-20 steel clevises (C, Figure 26) will need to
be adjusted. Loosen the 1/2-20 jam nut (B) that
tightens against the clevis. Remove the cotter
pin (E), and the clevis pin (D) that are connected
to the front deck lift pivot (A). Turn the clevis to
adjust the length of the rod. Reinstall the clevis
pin and the hair pin. Tighten the 1/2-20 jam nut.
Measure and record the distance between the lift
pivots and the rod pivots. Repeat the process until
the measurements are equal.
