Adjust the mower while tractor is parked on level ground 
or driveway.  Make sure tires are properly infl ated (See 
“PROD UCT SPECIFICATIONS” section of this manual).   If 
tires are over or underinfl ated, you will not properly adjust 
your mower.

•      Raise mower to its highest position.
•         At the midpoint of both sides of mower, measure height 

from bot tom edge of mower to ground.   Distance “A” 
on both sides of mower should be the same or within 
1/4" of each other.

•     If adjustment is necessary, make adjustment on one 

side of mower only.

•      To raise one side of mower, tighten lift link ad just ment 

nut on that side.

IMPORTANT:

  DECK MUST BE LEVEL SIDE-TO-SIDE. IF THE 

FOLLOWING FRONT-TO-BACK ADJUSTMENT IS NECESSARY,

To obtain the best cutting results, the mower housing 
should be adjusted so that the front is approximately 1/8" 
to 1/2" lower than the rear when the mower is in its high-
est position.

“D” directly in front and behind the mandrel at bottom edge 
of mower housing as shown.

both front links are equal in length.  

•      If links are not equal in length, adjust one link to same 

length as other link.

links an equal number of turns.

•     When distance “D” is 1/8" to 1/2" lower at front than 

rear, tighten nuts “F” against trunnion on both front 
links.

•      To raise front of mower, loosen nut “F” from trunnion on 

both front links. Tighten nut “E” on both front links an 
equal number of turns. The two front links must remain 
equal in length.
