42-, 48-, 52-inch (106.6, 121.9, 132.0cm) Mowers

The side-to-level and front-to-rear pitch adjustments for
all these models are the same. However, as you raise
the cutting height, the point at which the rear gage
wheels comes off the ground is different for the 52-inch
(132.0cm) mower. There is an adjustment process
when the mower is suspended. However, if the gage
wheels are on the ground, there is no side-to-side
adjustment. If the mower is not level side-to-side with
the gage wheels on the ground, look for a worn or
damaged wheel or bent gage wheel support (the bar
that connects the gage wheels).
With the deck suspended, the height of cut range for
the 42-inch and 48-inch (106.6cm and 121.9cm)
mowers is 2-3/4–4 inches (69.8–101.6mm). For the
52-inch (132.0cm) mower, it is 3–4 inches
(76-102mm).
The gage wheels on the 42-inch and 48-inch (106.6cm
and 121.9cm) mowers are on the ground in the height
of cut ranges 3/4–2-3/4 inch (19.0–69.8mm). The gage
wheels on the 52-inch (132.0cm) mower are on the
ground in the height of cut ranges 1-1/2–3 inches
(38-76mm).
