Blades

The condition of the blades will greatly effect the quality of the cut. The blades should be sharpened and bal-

anced 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 mini-

mize vibrations. Bent blades are a sign of a blade impact. If a bent blade is found, the blades must be replaced and
the spindles inspected for bent shafts and cracked housings.

Blades come in a variety of styles; side discharge, mulching, bagging, combination, there are even de-thatching

blades on the market. The decks available for the 2000 series comes with what Cub Cadet calls 3 in 1 blades. This
means they can side discharge, bag and mulch.

The cutting deck on a 2000 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.

To remove the blades:

Remove the deck as described in the deck removal
section of this chapter or lift the mower using a pro-
fessional grade lift.

Block the blade with a piece of wood to prevent it
from spinning.

NOTE: MTD blade holding tool 490-850-0005 can

be used to hold the blade while removing the
blade nut. See Figure 8.4.

Remove the blade nuts using a 1 1/8” wrench.
See Figure 8.5.
