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.
CAUTION: Blades are sharp. Protect 
your hands with gloves and/or wrap 
blade with heavy cloth.
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.

Adjust the mower while tractor is parked on level ground

level at front cor ners of mower.  Distance “A” on both 
sides of mower should be the same.
•     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.
•      To lower one side of mower, loosen lift link ad just ment 
nut on that side.
