Coarse Adjustment Procedure
When adjusting the deck level, the coarse adjustment 
procedure should be used to make the majority of 
the adjustment and the Fine Adjustment Procedure 
should be used to complete the adjustment.
 1.  Park machine on a flat, level surface.  Disengage 

the PTO, stop the engine and engage the parking 
brake.  Rear tires must be inflated to 18 psi (1,24 
bar); front tires to 25 psi (1,72 bar).

 2.  Lock the deck lift pedal in the 5” (12,7 cm) 

position.  Place the deck height adjustment pin in 
the 4” position and lower deck the lift pedal until 
the arm contacts the pin.

 3.  Place 2 x 4 blocks under each corner of the 

mower deck with the 3-1/2” sides being vertical.  
See Figure 49.

 4.  52” Models Only:  Loosen the nuts and allow the 

front of the deck to rest of the 2 x 4’s.  Slide the 
chains down in the slots until the chains and tight 
and tighten the nuts.  See Figure 50. 

 4a. 61” Models Only:  Adjust the front eyebolts until 

the chains are tight and the deck is still resting on 
the 2 x 4’s.  Tighten the jam nuts.  See Figure 50.

 5.  Loosen the nuts and allow the rear of the deck to 

rest on the 2 x 4’s.  Slide the chains down in the 
slots until the chains are tight and tighten the nuts.  
See Figure 50.

 6.  Remove all 2 x 4 blocks from under the mower 

deck.

 7.  See Figure 51.  Position the outside mower blades 

so they face front-to-back.

 8.  Measure from the front tip of the blade from the 

cutting edge to the ground.  Measure from the 
rear tip of the blade from the cutting edge to the 
ground.  Repeat this process for the other side of 
the machine.

 

•  The measurement should be 4” (10,2 cm).
