TO ADJUST ATTACHMENT CLUTCH
(See Fig. 26)
The electric clutch should provide years of service. The
clutch has a built-in brake that stops the pulley within 5
seconds. Eventually, the internal brake will wear which may
cause the mower blades to not engage, or, to not stop as
required. Adjustments should be made by your nearest
authorized service center/department.
• Make sure attachment clutch and ignition switches are
in “OFF” position.

TO ADJUST BRAKE (See Fig. 27)
Your tractor is equipped with an adjustable brake system
which is mounted on the side of the transaxle.
If tractor requires more than six (6) feet stopping distance at
high speed in highest gear on a level dry concrete or paved
surface, then brake must be adjusted.
• Depress clutch/brake pedal and engage parking brake.
• Measure distance between brake operating arm and nut
“A” on brake rod.
• If distance is other than 1-1/2", loosen jam nut and turn
nut “A” until distance becomes 1-1/2". Retighten jam nut
against nut “A”.
• Road test tractor for proper stopping distance as stated
above. Readjust if necessary. If stopping distance is
still greater than six (6) feet in highest gear, further
maintenance is necessary. Contact your nearest au-
thorized service center/department.
