3.6 Mower Deck Leveling Adjustment
The 721XRT Articulator mowing decks come leveled from the Lastec factory. Should deck
leveling be necessary due to shipping, usage, or maintenance, the following procedure
can re-level the decks as needed.
Leveling decks 1 and 3
Decks 1 and 3 attach to the deck cross tube by slid-
ing pivot ball joints. As of Serial Number
12381202
,
these joints can be adjusted by setting the cam
position of the deck adjustment cam.
Back off the central bolt going through the ball joint
and into the cam adjustment nut.
Do not remove
the bolt!
Pull out the deck adjustment cam nut to clear the
stop block. Rotate the cam to the desired position
to level the deck.
Tighten the central bolt. Note that the stop block prevents the cam adjustment nut from
rotating out of position.
Adjusting these decks may have an effect on Decks 6 and 7. Check for proper leveling of
all decks, and repeat if necessary.
Leveling Deck 2
Shims can be applied between the deck pan
mount and the cross tube. Shims may be
obtained from your Lastec dealer, part number
045446. These shims are 1/16th inch thickness.
