6.7.7 Adjusting Deck Height
To prevent material from entering drapers and cutterbar, maintain deck height so that draper runs just below
cutterbar with maximum 1/32 in. (1 mm) gap (A), or with draper deflected down slightly (up to 1/16 in. [1.5 mm]) to
create a seal.
NOTE:
Measurement is at supports with header in working
position and decks slid fully ahead.

start-up or fall of raised machine, always stop engine,
remove key, and engage safety props before going
under header for any reason. Refer to the windrower
operator’s manual for instructions regarding the
