When using the rear blade in a reverse position, use extra care. Do not ram rear blade into piles of dirt.
Tractor lift arms and the rear blade are not built to take high impact loads in this position. Ramming backwards
can also dislodge operator from seat and/or tractor controls, resulting in possible serious injury or death.
Always ease the tractor into the load. It may be necessary to reposition and take less “bite” on the material to
move it safely.
Watch for and avoid hidden obstructions, i.e., buried pipes, rocks, concrete piers, uneven concrete slabs,
stumps, etc., when operating.
INSTRUCTIONS
TRACTOR REQUIREMENTS
AND PREPA R ATION
The UB Series Rear Blades will fit most Category I
tractors equipped with a standard 3-point hitch. These
blades are designed for use on tractors up to 50
horsepower. For use on larger tractors, extra care is
required and it is strongly suggested that purchasing a
heavier rear blade be considered.
Check the tractor’s 3-point hydraulic lift system. It
should operate up and down smoothly and hold its
position when set. Refer to your tractor owner’s manual
or dealer for any adjustments necessary to put the 3point hydraulic lift system in good working order. (I&T
shop manuals will list most specifications and adjustment
instructions – available from most farm equipment
dealers.)
Tractor should be equipped with stabilizer bars,
adjustable sway chains, or sway blocks to keep the
implement from swinging side to side.
Smaller size tractors may need front counter weights to
counter-balance the weight of the implement.
It is recommended that the tractor be equipped with a
Rollover Protection System (ROPS) and a seat belt that
is used.
CAUTION!
Be sure your tractor is in good condition and
properly equipped with counter weights. Read all the
safety precautions and make sure all tractor
operators are familiar with the safety rules of tractor
operation.

ASSEMBLY AND MOUNTING
It is suggested that you mount the main frame on the 3point hitch of your tractor before assembling the blade as
follows:
1. Lower the 3-point hitch on your tractor to facilitate
mounting of the main frame of the blade to the tractor.
2. Insert the lift arm pins on the main frame into the ball
sockets in the lift arms of the tractor 3-point hitch. Pin
in place with linch pins (not furnished).
3. Attach the mast of the main frame to the tractor by
installing the tractor center (or top) link with a top link
pin (not furnished). Pin in place with a linch pin (not
furnished).
The main frame of the blade is now installed on the
tractor. You are ready to proceed with assembling the

INSTRUCTIONS (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. RAMMING backwards can also dislodge operator from
seat and/or tractor controls, resulting in possible
serious injury or death.
CAUTION!
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.
CAUTION!
O PE R ATION
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 3point 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 opposite 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.
GENERAL SAFETY
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 connect 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”.
OWNER SERVICE
TRANSPORTING
Pay particular close attention to the Safety Messages
regarding transport. Avoid unnecessary injuries and
equipment damage by exercising cautious, conscientious travel procedures.
Attaching the blade to the tractor increases the overall
length of the working unit. Allow additional clearance for
the blade to swing when turning.
Raise the blade as high as possible for transporting.
Always transport blade with blade centered on tractor.
Never attempt road travel with blade offset into the traffic
lane.
MAINTENANCE
W ARNING!
▲ Lower blade to ground or block securely, turn trac-
tor engine off, remove key and set brakes or place
shift lever in “Park” position.
▲ Before working underneath, raise 3-pt. hitch to
highest position and block blade securely.
Hydraulic system leakdown and failure of
mechanical or hydraulic system can cause equipment to drop.
STORING SAFELY
• Never store equipment with fuel in the tank inside a
building where fumes may reach an open flame or
spark. Allow engine to cool before storing in an
enclosure.
• Always store blade in a clean, dry location away from
children or livestock.
• Storage location should be level and solid to make
hitching and unhitching easy.
OPTIONS
The optional skid shoes provide cutting height adjustment to reduce the chance of blade or surface damage
during snow removal. This option is very helpful when
plowing gravel or loose stone driveways.
OPTIONAL
MODEL SK-6 SKID SHOE INSTALLATION
Attach the skid shoe mounting bracket to the 2nd and
3rd cutting edge holes from each end of the moldboard.
Insert the skid shoe in the mounting bracket and secure
with the 1/2” – 13NC x 11/2” long square head set screw
and jam nut. Be sure the skid shoes are turned so the
adjustment holes match the point of the set screw. See
parts illustration.
▲ Keep all persons away from operator control area
while performing adjustments, service or maintenance.
▲ Do not run engine indoors – exhaust gases
contain carbon monoxide, an odorless and deadly
poison.
Inspect the blade for loose, damaged or worn parts and
adjust or replace if needed.
Repaint parts where paint is worn or scratched to
prevent rust.
Check all bolts and nuts to be sure they are tight.
At the end of the working season or when the blade will
not be used for a long period, it is good practice to clean
off any dirt that may have accumulated on the blade and
any of the moving parts.
Check the shift pin for excessive wear and replace if
necessary.
Always store blade in a clean, dry location away from
children or livestock.
Optional end plates provide a “boxed” blade for grading. This is helpful when spreading dirt or loose stone or
just leveling an area. It keeps the material from sliding off
the end of the blade.
OPTIONAL
MODEL EP-38 END PLATE INSTALLATION
The end plates mount to the inside of the blade using
the end cutting edge hole and the hole in the moldboard
directly above it. Replace the cutting edge bolt with the
longer 5/8” – 11NC x 2” long carriage bolt provided. On
earlier models it may be necessary to match drill the
upper 11/16” Dia. hole in the moldboard. Install the upper
5
/8” – 11NC carriage bolt. See parts illustration.

SAFETY PRECAUTIONS
MOST ACCIDENTS OCCUR BECAUSE OF NEGLECT OR CARELESSNESS.
AVOID NEEDLESS ACCIDENTS BY FOLLOWING ALL OF THE SAFETY PRECAUTIONS LISTED BELOW.
• Machinery should be operated only by those who are
responsible and are authorized to do so.
• Stop the engine, lower all equipment, lock the brakes,
and remove the ignition key before dismounting from the
tractor.
• Never stand between tractor and implement while tractor
is being backed to hitch.
• Loose fitting clothing should not be worn, to avoid catch-
ing on various parts.
• Detach implement in area where children normally do not
play.
• When performing adjustments or maintenance on an
implement, first lower it to the ground or block it securely
at a workable height.
• Only a qualified operator should be permitted on tractor
when in operation; no riders allowed.
• Make certain everyone is in the clear before starting
tractor or raising or lowering equipment.
• Operate the tractor and implement only while seated in
the driver’s seat.
•
Reduce speed when transporting mounted implements
to avoid bouncing and momentary loss of steering
control.
• A heavy load can cause instability of the tractor. Use
extreme care during road travel. Slow down on turns and
watch out for bumps. Tractor may need front counterweights to counter-balance the weight of the implement.
• Reduce speed on hillsides or curves so there is no
danger of tipping.
• Avoid driving too close to the edge of ditches or creeks.
• Do not transport implement on public roads without
reflectors and slow moving vehicle emblem in daylight
and with approved warning lights at night and other
periods of poor visibility.
• Due to the width of some implements, use extra caution
on highways, farm roads, and when approaching gates.
• Always be sure the implement is in the proper position for
transport.
• Keep alert and watch the front as well as the rear when
working with the implement.
