SERVICE AND ADJUSTMENTS

FRONT-TO-BACK ADJUSTMENT (See Figs. 16 and 17) 

IMPORTANT:

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

FOLLOWING FRONT-TO-BACK ADJUSTMENT IS NECESSARY, 
BE SURE TO AD JUST BOTH FRONT LINKS  EQUAL LY  SO 

MOWER  WILL STAY LEVEL SIDE-TO-SIDE.     

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.

Check adjustment on right side of tractor.  Measure dis tance 
“D” directly in front and behind the mandrel at bottom edge 
of mower housing as shown.
•      Before making any necessary adjustments, check that 

both front 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 mower loosen nut “E” on both front 

links an equal number of turns.

TO LEVEL MOWER HOUSING

Adjust the mower while tractor is parked on level ground 
or driveway.  Make sure tires are properly infl ated (See

your mower.

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.
