Checking and Adjusting the Blade Level
Adjusting Side-to-Side Level with Mower Suspended
The distance from the outside blade tips to the ground
should be equal within 3/16 inch (4.6mm) (Figure 56). If
not, an adjustment is in order.

1. Loosen adjustment bolt on one side and rotate
hangar bracket to raise or lower mower.
2. After adjusting, tighten bolt and check side-to-side
level.
IMPORTANT: If hangar is rotated to the end of
adjustment on one side and mower is not level,
adjust the opposite side.
Front-to-Rear Pitch
All mowers for the 260 series tractor use the same
pitch measurement. The blade should be 0-3/8 inch
(0-9.4mm) lower in front than in the rear. If it is not
within this specification an adjustment is necessary.
1. To adjust the front-to-rear pitch, loosen jam nut on
front adjustable link. Note: The 42-inch (106.6cm)
mower comes with one adjustable link standard,
although someone could have installed a second
one. The 48-inch and 52-inch (121.9cm and
132.0cm) models have two adjustable links
(Figure 57).

2. Rotate the bolt on front adjustable link(s) to
change the blade pitch. To raise the front of the
mower, shorten the adjustable link by turning bolt
clockwise. To lower front of mower, turn bolt
counterclockwise.
3. When front-to-rear pitch is correct, tighten jam nut.
Recheck side-to-side mower level (see “Adjusting
Side-to-Side Level with Mower Suspended”).
Blade Tracking—All 260 Series
On mowers with multiple blades, not only do the blades
need to be a minimum of 1/8 inch up from the bottom
edge of the housing, but they must also line up where
the tips come together. Take the two blade tips and
point them towards each other. They must be within
1/8-3/16 inch of level with each other, or both must be
the same distance from the blade to the ground
(Figure 58).
