Service Dealer’s Guide to Great Quality of Cut 4 - 21
Checking and Adjusting the Blade Level
60-inch (152.4cm) Mower
The mower blades should also be level side-to-side
within about 3/16 inch (4.76mm). The adjustment is
made on the gage wheels as shown (Figure 66).

Adjusting Front-to-Rear Pitch
All the cutting units for this series tractor should be
adjusted so that the blade is approximately 1/8 inch
(3.1mm) lower in front.
To adjust the pitch, turn the adjusting nut on the rear of
the mower attachment. To raise the front of the mower,
turn the adjustment nut clockwise. To lower the front of
the mower, turn the nut counterclockwise (Figure 67).

Adjusting Transport Blade Pitch
Because the attachment lift is used when the PTO drive
is engaged, blade pitch in transport must be adjusted
to extend PTO drive belt life. This adjustment also
provides for adequate transport height. In the transport
position, the blade tip should be about 1/4 inch
(6.3mm) lower in front than in the rear. If adjustment is
necessary proceed as follows:
1. Start the tractor, lower the attachment lift to take
pressure off the adjustment cams. Stop the engine
and remove the key.
2. Loosen the cam nuts and equally rotate the
left-hand and right-hand cams down to raise the
front of the mower, or up to lower the front of the
mower (Figure 68). Tighten the nuts. Repeat as
necessary.
