First and Second Hole From Center

• This position is used for cleaning shallow ditches. • Processing and moving large windrows.

• Used with articulation to build narrow flat bottom ditches and backfill curb radiuses.

Third Hole From Center

• This position is used for cutting ditch back slopes and high bank slopes. • Cleaning deep ditches. • Grading and dressing fill slopes. • Disposing of sod and oversize rock on backslopes.

• Use with articulation to grade on steep slopes. There are two recommended techniques for repositioning the linkbar. The first technique is for repositioning to the first or second hole either side of center. The second technique is for repositioning to the third or farthest hole from center. Assume the ditch or slope to be worked is to your right.

1. To reposition to the first or second hole either side of center, shift the drawbar/circle assembly to its maximum position towards the ditch/slope to be graded. Ground the moldboard by placing both lift cylinders in the float position. With the moldboard grounded, release the centershift lock pin with the toggle switch. When the light on the front console is illuminated, the pin is retracted.

With the lift cylinders still in the float position, move the centershift away from the ditch/slope to be graded. Example: If the centershift was moved to the right before grounding the moldboard and pulling the pin, now move the centershift to the left. As the centershift cylinder is either retracted or extended (depending on the direction the linkage is being moved), the linkage will roll around freely moving the linkbar sideways. Line up the hole using the gauge on the back of the right lift-cylinder mount. Insert the pin with the toggle switch. When the light on the console goes out, the pin is in. Now sideshift the drawbar towards the slope to be cut and use the lift cylinders to adjust the slope angle to be cut.

2. To reposition to the third or farthest hole from center, start with the same procedures as listed above to release the pin. Once the pin is released take the lift cylinders out of float. Simultaneously lower the right end of the blade, move the center shift to the left and raise the left end of the blade. This will allow the linkbar to move into the third hole position.
