The cutting height is the d istance between the blade
and the ground. The blades are 7-3/4” below the top
of the deck rail on the GM1060S (8-3/4” below the top
of the deck rail on the GM1072S). To check cutting
height, place a straight edge along top edge of deck
rail as shown in Figure 4.
Measure from bottom of straight edge to the ground
at locations A and B. Subtract 7-3/4” on GM1060S
(8-3/4” on GM1072S) from measurement B to
determine cutting height.

Tractor Top Link Adjustment
(Figure 3 & Figure 5)
Adjust tractor top link so mower is level at 16”
between caster wheel and ground (dimension C,
Figure 5). This will allow the mower to follow g round
contour.
Front Caster Wheel Interference Check
(Figure 5)
IMPORTANT
J Do notoperatetractor and mower until
this interference check has been per-
formed. If you change tractors, you must
perform the check for that mounting.
Perform this check with all of the spacers and springs
above the caster wheel arm. This will place the caster
wheels in their highest position and provide the lowest
cutting height for the mower.
Raise m ower with tractor hydraulics to 16” at
dimension C or maximum height of tractor lift,
whichever is less.
Pivot both front caster wheels forward and check that
there is clearance between caster wheels and tractor
tires. If there is interference, you must not use front
caster wheels on the mower with this tractor .

Front Roller (Optional)
The caster wheels and side skids effectively reduce
scalping in most cases. However, you may encounter
areas where the caster wheels and/or side skids drop
into depressions and allow center of mower to contact
ground and scalp. An optional front roller may be
installed to minimize scalping.
