Disassembly (Fig. 9)
1. Park machine on a level surface, lower cutting deck
(or implement), stop engine and remove key from the
ignition switch.
2. Remove front panel under the operator seat (Fig.
10).
3. If removal of brake handle (item 12) is necessary:
A. On both sides of machine, unlatch spring pin from
brake linkage yoke. Remove spring pin from yoke
and brake handle brackets.
B. Support brake handle to prevent it from shifting or
falling.
C. Remove cap screws and lock nuts that secure
flange bearings to frame.
D. Remove brake handle and flange bearings from
machine.
4. Remove additional parking brake components as
necessary using Figure 9 as a guide.
Assembly (Fig. 9)
1. Assemble parking brake components as necessary
using Figure 9 as a guide.
A. If brake linkage yoke was removed from front
brake rod, install yoke onto rod so that center to cen-
ter length is from 8.290” to 8.350” (21.1 to 21.2 cm)
(Fig. 11).
B. Make sure that cap screws (item 10) used to se-
cure flange bearings (item 17) are installed from the
outside of the frame to the inside.
2. After assembly of brake system, apply parking brake
and check length of compression spring on rear brake
rod. Spring length with brake applied should be from
2.880” to 3.000” (7.4 to 7.6 cm) (Fig. 12). If necessary,
adjust spring length with hex nuts on rear of brake rod.
3. Check operation of parking brake and parking brake
switch.
4. Install front panel to the machine (Fig. 10).
1. Front panel 2. Washer head screw
