2. Measure the distance from the left front blade tip to
the ground and from the right rear blade tip to the ground.
The front left blade tip should be between 1/8" and 3/8"
higher than the right rear (factory setting). If it is between
1/8" and 3/8" you are finished with adjustment.

lowering the front of the deck using the swivel on the front
lift rod. Turning the swivel clockwise will raise the front of
the deck. Turning the swivel counterclockwise will lower
the front of the deck.
NOTE: The deck should be set so that the rear of the deck
is 1/4" lower than the front. See Figure 4.17.
