CUTTING DECKS AND LIFT SHAFT
144
Cleaning the deck
Cleaning debris off of the deck should be done
every time the deck is removed. It is routine mainte-
nance that will make the deck easier to work on and
prolong the life of the deck and spindles.
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
vulnerable to diseases.
Blades need to be examined for damage before
sharpening. 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 I-series comes
with what Cub Cadet calls a 3 in 1 blade. This means it
can side discharge, bag and mulch.
The cutting deck on the I-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.
Debris build up on the mower deck
is an unsafe condition. The debris
traps heat in the spindles causing
damage to the spindle bearings. Debris around the
belt can over-heat.
