4.2.5.  MOWER DECK ADJUSTMENT (LEVELNESS) 
   SIDE-To-SIDE (48” Decks) 
Before making deck leveling adjustments, check the 
tire pressure. Check tires and add or release air as 
needed to bring pressure to 12 PSI in front and 12 
PSI in rear tires. If tires are properly inflated and 
mowing is still uneven, adjust side-to-side deck 
levelness as follows: 
1.  Place machine on a smooth level surface. 
2.  Rotate outside blades so tips are pointed to the 
sides of deck. See Figure 4.6. Measure the 
distance from blade tips to floor. If the 
measurement is within 1/8” from side-to-side, the 
deck levelness is satisfactory. If the difference 
from side-to-side is greater than 1/8”, continue to 
next step for adjustment.  
3.  Place a 2 x 4 piece of wood under the front 
middle portion of deck. Place one 2 x 4 piece of 
wood under the rear of deck on both sides behind 
the two outside blades. See Figure 4.6. 
4.  Lower deck down to rest on the three 2 x 4 
pieces of wood. Make sure there is no deck 
tension on the lift rods supporting the deck. 
5.  Loosen the bolt and nut that secures the front lift 
arm weldment to the front lift arm. See Figure 4.7.
