BLADE ARTICULATION

The dozer blade is designed with +/- 5 degrees of 

lateral articulation to allow the blade to follow the 

contour of the ground. If the blade is not following 

the ground contour, adjust the articulation with the 

following steps:

Blade Articulation Adjustment

1.  With the tractor on a flat, level surface, raise 

the blade.

2.  Loosen the articulation joint bolts by one turn 

on each side until the blade can be fully articu-

lated by pushing down on the edge of the 

blade. The pivot plates should always remain 

fully in contact with each other; there should 

never be a gap or play in the joint.

  CAUTION

Do not over loosen the articulation joint.  

Doing so could cause the blade to fall off 

during use causing damage to the blade or 

property.

3.  Then lower the blade, and it should easily self 

level to make full contact with the ground as it 

is lowered.

Blade Articulation Lock

The blade articulation can be locked to render the 

blade fixed. 

1.  On a flat surface, lower the blade to rest on the 

ground. 

2.  Fully tighten the bolts on both sides of the 

articulation joint.  

3.  Raise the blade and push down on one side; 

the blade should not move.

  CAUTION

Do not lock the articulation at an angle oth-

er than parallel to the ground.  Doing so 

could  cause  significant  damage  to  the 

blade or property.
