4. Measure distance between end of compression
spring bracket (C) and front edge of brake rod stop
tabs (D).
• If distance is less than 2 mm (0.08 in.)—
5. Tighten lock nut (E) until distance between end of
compression spring bracket (C) and front edge of
brake rod stop tabs (D) is 7.5—8 mm (0.30—0.32
in.)
6. Once above measurement is obtained, cycle clutch/
brake pedal.
7. Remeasure distance, it should be the same. This
brake setting should hold the tractor stationary on a
17° slope.
If distance is greater than 8 mm (0.32 in.)—
8. With park brake set, gradually loosen lock nut (E)
until distance of 7.5—8 mm (0.30—0.32 in.) is
obtained.
9. Cycle park brake and measure distance again (see
Step 7).
10. If tractor fails either brake test, inspect brake
assembly components, replace as necessary, and
repeat all adjustment procedures and drive tests.
