FRONT-TO-BACK ADJUSTMENT (See Figs. 22 and 23) 

IMPORTANT:  DECK MUST BE LEVEL SIDE-TO-SIDE.  IF THE 
FOLLOWING FRONT-TO-BACK AD JUST MENT IS NECESSARY, 
BE SURE TO ADJUST BOTH FRONT LINKS EQUALLY SO 
MOWER WILL STAY LEVEL SIDE-TO-SIDE.

To obtain the best cutting re sults, the mower blades should 
be adjusted so the front tip is ap prox i mate ly 1/8" to 1/2" 
lower than the rear tip when the mower is in its highest 
position.

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.

•      Measure height from bottom edge of mower to ground 

level at front cor ners of mower.  Distance “A” on both 
sides of mower should be the same.

nut on that side.

•      To lower one side of mower, loosen lift link ad just ment

Check adjustment on right side of trac tor.  Position any blade 
so the tip is pointing straight forward. Measure distance "B" 
at front and rear tip of the blade.
•      Before making any necessary ad just ments, check that 

both front plate links are equal in length.

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

length as other link.

•     To lower front of blade, loosen nut “C” on both front 

links an equal number of turns.

NOTE:  Each full turn of nut “C”  will change distance. “B” 
by approximately 3/16". 
•         When distance “B” is 1/8" to 1/2" lower at front than rear, 

tighten nut “D” against trunnion on both front links.

•      To raise front of blade, loosen nut “D” from trunnion on 

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