Section 4 - ADJUSTMENTS & REPAIR 

 

WARNING 

DO NOT attempt any adjustments, maintenance, 
service or repairs with the engine running. STOP 
engine. STOP blade. Engage parking brake. Remove 
key. Remove spark plug wire from spark plug and 
secure away from plug. Engine and components are 
HOT. Avoid serious burns, allow all parts to cool 
before working on machine. Fuel Filler Cap and vent 
must be closed securely to prevent fuel spillage. 

 

4.2.2.  MOWER DECK ADJUSTMENT  

(Side-To-Side Levelness) 

Before making deck leveling adjustments, check the 
tire pressure.  Front tires 12 psi, rear tires 12 psi. If 
tires are properly inflated and mowing is still uneven, 
adjust side-to-side deck levelness. 
1.  Place Rider on a smooth level surface. 
2. Turn engine off and remove key, remove spark 
plug wire from spark plug and secure wire away from 
plug. 
3.  Place a piece of angle iron, pipe, or similar object 
under center of deck at the rear. 
4.  Remove rear hanger chains and allow center, rear 
of deck to rest on angle iron. 
5.  Measure the distance from blade tips to floor. If the 
measurement is within 1/8” from side-to-side, the deck 
attitude is satisfactory.  If difference from side-to-side is 
greater than 1/8”, continue with adjustment. 
6.  Loosen the shoulder bolt retaining the left side of 
blade pedals. 

 

 

 

FIGURE 4.3 

7. Turn eccentric “UP” or “DOWN” as required until 
blade tips are within 1/8” of each other.  See Figure 
4.3. 
8.  Tighten shoulder bolt loosened in Step 6. 
9. Readjust rear hanger chain pivots to align with 
holes in support brackets. 
See Figure 4.4. 
10.  Remove angle iron, pipe, or similar object and 
proceed to check front to rear levelness. 
 

4.2  MOWER DECK & COMPONENT ADJUSTMENTS 

4.2.3.  MOWER DECK ADJUSTMENT  

(Front to Rear Levelness -  28”, & 33” Decks) 

With the Rear Engine Rider on a smooth, level 
surface, rotate blade until blade tips are at front and 
rear of deck.  Measure the distance from blade tips 
to floor.  The distance should be the same, or the 
rear 1/8” to 1/4” lower than the front.  If the rear 
blade tip is higher or is more than 1/4” lower than 
the front, proceed with adjustment. 
 

(Front to Rear Levelness - 30” Decks) 

With the Rear Engine Rider on a smooth, level 
surface, rotate blade until blade tips are at front and 
rear of deck. Measure the distance from blade tips 
to floor. The distance should be the same, or the 
rear 1/8” higher than the front.  If the rear blade tip 
is higher or is more than 1/8” higher  than the front, 
proceed with adjustment. 
1.  Remove rear hanger chains. 
2. Turn each hanger pivot the same number of 
rotations on the eye-bolt to raise or lower the rear of 
the deck.  See Figure 4.4. 
3.  Reinstall rear hanger chains and measure blade 
tips again. 
4. Repeat steps “1” through "3” until proper 
levelness is obtained.
