8. To reduce the weight of lifting the deck before
the counterweight spring is installed, remove
one (1) deck height hitch pin from a rear deck
support pin or alternately lift and block one
side of the deck. Decks with a deck height
adjuster installed will need to use the lift and
block technique.
Remove One Deck Height Hitch Pin
9. Re-engage the deck lock lever on the side
with the deck height hitch pin removed then
re-engage the second deck lock lever. Rein-
stall the deck height hitch pin or remove the
block.
Do not operate the machine with the deck

ening the elastic stop nuts located underneath
the lower spring hook, or contact your local
dealer if additional help is required. Refer to
