21.4. Characteristics of brakes that are too tight, con-
tinued:
• High effort required to pull up the lever that
applies the parking brake. Some “phantom”
resistance may be created by the over-center
action of the interlock linkage.
21.5. Brakes that are too loose are characterized by:
• Low effort required to pull up the lever that
applies the parking brake. Some “phantom”
resistance may be created by the over-center
action of the interlock linkage.
• The mower can be pushed (or the wheels
rotated) manually, with the relief valves open
and the brake applied.
21.6. Before making adjustments, make a visual
inspection of the brake linkage. Watch the link-
age as it is being operated, and check for:
See Figure 21.6.
• Loose, broken, or disconnected linkage compo-
nents.
• Components that are binding because of corro-
sion, foreign objects, or misalignment (bent
links).
• Loss of travel because of worn bushings or hard-
ware.
21.7. Each brake adjustment nut can be reached
through an opening between the hydro service
plate and the control housing. See Figure 21.7.
• There is one adjustment point for each side of
the mower.
• Adjustment can be made using a deep 9/16”
socket.
21.8. The brake rod is moved by an output arm
attached to the brake pivot shaft assembly.
There is a compression spring on each side of
the contact point. Tightening the nut puts more
pressure on those springs, loosening the nut
reduces the pressure on the springs.
See Figure 21.8.
