LeeBoy 685D - Operating a Scarifier; Replacing Scarifier Teeth

Operating a Scarifier
Use the following procedure for scarifying roads or
other areas using the optional rear scarier:
1. Raise the moldboard at least one foot (.304 m) off
the ground to allow unrestricted movement. Rotate
the moldboard so that it is perpendicular with the
frame and pitch the blade forward halfway.
2. Position the grader ahead of the working area and
ensure the front wheels are vertical.
3. Slowly move the grader forward.
If the rear wheels lose traction, raise
the scarier until the wheels regain traction.
4. At the starting point for the job and while still moving,
lower the scarier.
• If equipped with a rear scarier, use the rear
scarier lever shown in Figure 4-46.

5. When nished with the rst pass, raise the scarier
by pulling rearward on the scarier lever.
6. If more passes are needed, repeat the procedure.
DO NOT remove more than ve teeth
as the force against the remaining teeth could shear
them off.
Replacing Scarifier Teeth
The scarier tooth supports are adjustable and secured
with pin locks.
Always support the scarier and other
attachments using a block or sling before servicing.
1. Raise the scarier. Support the scarier on
blocks or use a sling for support.
2. Using a pry bar or lock pin tool, remove the shank
lock pin and tooth from the scarier frame. (Figure
4-47)
• If only removing tooth, be sure to store tooth
shank and locking pin together for later use.

hammer if you wish to hammer the lock pin back into
place to prevent damage.
