Only one end of blade
moldboard cutting or
“working.” 1. Moldboard not level. Adjust tractor 3 pt. linkage to level
lift arms.
Blade moves side to
side. 1. Anti-sway bars, blocks, or chains
missing.
2. Anti-sway chains loose.
Install anti-sway bars, blocks or
chains.
Adjust chains.
Angle shift pin breaks
or bends. 1. Hitting solid objects.
2. Ramming blade into “solid” snow/ice
or dirt piles.
3. Using too large tractor.
Drive carefully and check work
area.
Stop dangerous practice.
Use proper size tractor for blade
rating.
Blade catches
cracks/joints in hard
surface driveways.
PLOWING SNOW PROBLEMS:
1. Need optional skid shoes. Add skid shoes.
Blade plows most loose
stone/gravel into grass
at side of driveway. 1. Skid shoes not adjusted properly. Adjust skid shoes so cutting edge
clears.
Front of tractor moves
sideways when blade is
angled. 1. Too much material being handled.
2. Tractor too light.
Reduce material load.
Add front weights.
Use larger size tractor.
I N S T R U C T I O N S (continued)
When using the rear blade in a reverse position use
extra care - DO NOT RAM REAR BLADE into dirt
piles! Tractor lift arms and the rear blade are not
built to take high impact loads in this position. RAM-
MING backwards can also dislodge operator from
seat and/or tractor controls, resulting in possible
serious injury or death.
C A U T I O N !
Watch for and avoid hidden obstructions, i.e.,
buried pipes, rocks, concrete piers, or uneven slabs
of concrete, when operating, or blade damage may
occur. This is especially true when removing snow.

O P E R AT I O N
Check for ditches, stumps, holes, or other obstacles
that could upset tractor or damage blade. Always turn off
tractor engine, set parking brake, lower blade to ground
before dismounting tractor.
Attaching the blade to the tractor increases the overall
length of the working unit. Allow additional clearance for
the blade to swing when turning.
Your rear blade can be used for all types of blade
work, including casting, side ditching, leveling, terracing,
grading, bulldozing, and snow removal.
1. CASTING: The blade should be angled horizontally –
only enough to allow the 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.
2. 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 adjustable turnbuckles on the tractor 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.
3. 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 0˚ vertical angle, i.e., the lift arms
on the tractor 3-point hitch should be parallel to the
ground.
The cutting pitch of the blade should be the oppo-
site of that used in side ditching and casting, with the
cutting edge behind the top edge of the moldboard.
This adjustment is made with tractor center link.
4. 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
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.
5. BULLDOZING: When bulldozing, the blade is in
reverse position. Depending on the job, the casting,
side ditching, or leveling position may be used. Snow
removal can also be done with the blade in this
position (blade in reverse, cutting edge away from
tractor).
(NOTE: Most blades are damaged in this position –
use extra care – DO NOT RAM blade into snow or
dirt piles!)
6. GRADING: Grading is a combination of casting, side
ditching, and leveling. Snow removal can also be
done with the blade in this position (cutting edge
toward the tractor).
These suggestions are generalities; best results will be
obtained after some experience.
NOTE: Do not load either end of the blade heavily. Try
to balance the load on both ends of the blade.

The designed and tested safety of this machine
depends on it being operated within the limitations as
explained in this manual. Be familiar with and follow all
safety rules in the manual, on the blade and on the
tractor.
The safe operation of this machine is the responsibility
of the owner / operator. The operator should be familiar
with the blade and tractor and all safety practices before
starting operation. Read the safety rules.
Never let anyone stand between the rear of the tractor
and the rear blade while the tractor is backing up to con-
nect to the blade. Always stand to the side until tractor
has come to a complete stop and the brakes set or the
tractor shift placed in “PARK”.
