Cutting Deck Removal and Installation
Removal
1. Park machine on a level surface with the cutting deck
in the fully raised position. Stop engine, engage park-
ing brake and remove key from the ignition switch.
NOTE: When the cutting deck is in the raised position,
pull link torsion spring tension is reduced making it much
easier to disconnect pull links from machine.
2. Disconnect pull link from each side of machine (Fig.
1):
CAUTION
Be careful when disconnecting the pull links.
The pull link torsion springs may cause some
rotation of pull links during the removal process.
A. Remove shoulder screw that secures retainer pin
to carrier frame.
B. Carefully slide retainer pin from carrier frame and
pull link.
3. Note location of HOC pin in HOC bracket for assem-
bly purposes (Fig. 2). Remove HOC pin from HOC
bracket.
4. Start engine and fully lower cutting deck. Stop en-
gine and remove key from the ignition switch.
WARNING
Do not start the engine and engage the PTO
switch when the PTO drive shaft is discon-
nected from the cutting deck. If the engine is
started and the PTO shaft is allowed to rotate,
serious personal injury and machine damage
could result. If the PTO drive shaft is discon-
nected from the cutting deck, remove fuse F1
(15 amp) from fuse block to prevent uninten-
tional engagement of the PTO clutch.
5. To prevent unintentional engagement of the PTO
clutch, remove fuse F1 (15 amp) from fuse block.
