Cutting Decks And Lift Shaft

Cleaning the deck
Cleaning debris off of the deck should be done every
time the deck is removed. It is routine maintenance that
will make the deck easier to work on and prolong the
life of the deck and spindles.
DANGER:
Debris build up on the mower deck is
an unsafe condition. The debris traps heat in the
spindles causing damage to the spindle bear-
ings. Debris around the belt can over-heat.
To clean the deck while it is removed:
1.
Blow all the debris off of the top of the deck
using compressed air.
2.
Scrape off the debris build up from the under
side of the deck using a plastic scraper.
NOTE:
Applying a light coating of oil to the
underside of the deck after scraping it clean will
help prevent rusting of the deck and help keep
the debris from building up on the underside of
the deck.
Blades
The condition of the blades will greatly effect the quality
of the cut.
The blades should be sharpened and balanced after
every five acres, depending on local conditions. A dull
blade tears the grass instead of cutting it. Torn grass
blades leaves a rough look and makes the grass vul-
nerable to diseases.
Blades need to be examined for damage before sharp-
ening. Blades must be balanced after sharpening to
reduce the vibrations felt from the deck.
Bent blades are a sign of a blade impact. The blades
must be replaced and the spindles inspected for bent
shafts and cracked housings if a bent blade is found.
Blades come in a variety of styles; side discharge,
mulching, bagging, combination, there are even de-
thatching blades on the market.
The cutting deck on the 900 series tractor is mounted
with a slight rake, meaning that the front of the deck is
a 1/4” - 3/8” lower than the rear of the deck. This is very
important to get the proper air flow in the deck so that
the blades can make the grass blades stand up to get
cut.
The air flow in the cutting deck is generated by the
spinning blades. If the blades are mounted upside
down, the air flow will be reversed pushing the grass
down instead of standing up.
NOTE:
Blades that are mounted upside down,
increase the risk of impacting an object.
