Adjustable Grader
Blades
Adjustable Grader blades have tilt, angle and
offset capabilities. To make adjustments, loosen
bolts, make the necessary changes, and
retighten all nuts securely. The lift arms on the
tractor can be used for additional adjustments
(see below).
Fixed Grader Blades
Casting
The blade should be angled horizontally - only
enough to allow material to slide along it easily.
The vertical angle (tilt) of the blade must be set
to suit conditions. This is controlled by the lift
arm leveling assembly (turnbuckle) on the
tractor 3-Point hitch.
Side Ditching
The horizontal angle should be at its sharpest.
This is obtained by removing the shift pin and
turning the moldboard so that the last hole in the
circle plate is in line with the shift pin hole, then
replace the shift pin. It is suggested that the
blade be set in an offset position and then use
the shorter blade side to be the cutting side. This
reduces the load movement on the end of the
blade.
The vertical angle of the blade (tilt) is adjusted
by means of the adjustment turnbuckles on the
tractors 3-Point hitch. For the sharpest angle,
lengthen the center link on the tractor as far as
possible. Also, lower the adjustable leveling
turnbuckle as far as possible.
Leveling
The blade should be straight across, (i.e. 90° ) to
the line of travel of the tractor, in other words 0°
horizontal angle. There should be a 0° vertical
angle, the lift arms on the tractor’s 3-Point hitch
should be parallel to the ground.
The cutting pitch of the blade should be the
opposite of that used in the side ditching and
casting, with the cutting edge behind the top
edge of the moldboard. This adjustment is made
with the tractor center link.
Terracing
Use a combination of ditching, casting, and
leveling. The first cut is into the hillside in the
ditching position. Continue until the terrace is at
the proper depth, then switch to the casting
position until the terrace width is established. It
may be necessary to use the leveling position to
complete the job.
Bulldozing
When bulldozing, the blade is in the reverse
position. Depending on the job, the casting, side
ditching, 0° leveling position may be used. Snow
removal can also be done with the blade in this
position (blade in reverse cutting edge away
from the tractor).
When using blade in a reverse position, use
extra care - DO NOT RAM BLADE into dirt or
snow piles! Tractor lift arms are not equipped
to take high impact loads in this position.
Grading
Grading is a combination of casting, side
ditching, and leveling. Snow removal can also
be done with the blade in this position.
Watch for hidden obstructions, like buried
pipes, rocks, concrete piers or uneven slabs
of concrete when operating the Grader Blade
as damage to the unit can occur. This is
especially true with snow removal.
Maintenance
Before servicing the Grader Blade, engage
the parking break or place the transmission in
“PARK”, shut off tractor, and remove key.
1. Make certain any safety and instruction decals
are attached to the Grader Blade 3-Point
hitch. If they are lost, damaged, or painted
over, order replacements from Behlen
Country at 1-800-447-2751.
2. Telescoping parts must be kept clean and
lubricated.
