NOTE: 

There has been some issues with the 

deck belt rubbing on the Deck Hanger Link/Anti-
Sway Rod on tractors with the 46” cutting deck. 
(Model 13AQ683H163) This has been corrected 
on later production by moving the deck anti-
sway bracket higher. If you are experiencing belt 
damage contact MTD Customer Service for a 
hanger link with a bend in it. See Figure 6.

NOTE: 

Check the tractors tire pressure before 

performing any deck leveling adjustments.

5.1.

Perform deck leveling by removing the hairpin 
clip from the front left hanger bracket and adjust 
the ferrule up or down to set side to side level. 
See Figure 7.

SETTING THE DECK WHEEL HEIGHT (ON     
MODELS SO EQUIPPED).

6.1.

Select the height position of the cutting deck by 
placing the Deck Engagement / Lift Lever in any 
of the five different cutting height notches on the 
right side of the frame.

6.2.

Adjust the deck wheels so that they are between 
1/4 inch and 1/2-inch above the ground when 
the tractor is on a smooth, flat surface such as a 
driveway and the height adjuster is in the lowest 
position.

WARNING: 

Keep hands and feet away from the 

discharge opening of the cutting deck

NOTE: 

 The deck wheels, on models so 

equipped, are an anti-scalp feature of the deck 
and are not designed to support the weight of 
the cutting deck.

7.

DECK ENGAGEMENT ADJUSTMENT

NOTE: 

The deck must disengage when the deck 

engagement/lift lever is in the blade stop posi-
tion.

Adjust as follows.

7.1.

With the engine off, place the deck engagement/
lift lever in the top cutting position (not BLADES 
STOP position). See Figure 8.
