DECK LIFT
5.1.
In an advancement over the box-frame design,
the deck height and engagement functions are
isolated from one-another.
5.2.
The deck lift control, located on the right fender,
rotates a cross-shaft and two slotted bell-cranks
(lift shaft assembly) that draw up and back on
the deck lift rods.

NOTE: The slotted configuration of the bell-
crank arms suspends the deck, yet allows it to
float upward as the anti-scalp wheels encounter
bumps.
5.3.
The the deck lift links are distinct from left to
right: there are two different part numbers.
See Figure 5.3.
