Safety Information
Keep alert and watch the front as well as the rear when working with the implement.
When maneuvering close to buildings or passing through narrow areas, be sure to allow sufficient clearance
for the implement.
Do not operate close to ditches or creeks. Slow down when operating over rough ground.
Always be sure the implement is in the fully raised position when in transport.
When adjusting the angle of the moldboard assembly, be sure that your feet are never under the rear blade.
Use extreme caution when backfilling deep holes or trenches.
Be careful to avoid catching the rear blade on stumps or other immovable objects.
Use care when working on slopes.
Avoid excessive speed during operation.
Make adjustments only when the implement is attached to the tractor.
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.

TRACTOR REQUIREMENTS
AND PREPA R ATION
INSTRUCTIONS
ASSEMBLY AND MOUNTING
The Model MCB-6 Rear Blade will fit most Category I
tractors equipped with a standard 3-point hitch. The rear
blade will fit Category 0 3-point hitch tractors when
equipped with Category 0/I pull pins.
The pins need to be installed to the inside of the 3-point
frame for use with Category 0 tractors.
The model MCB-6 Rear Blade is an economy blade for
use on Category I tractors up to 30 horsepower in size.
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.
Be sure your tractor is in good condition. Read all
the safety precautions and make sure all tractor operators are familiar with the safety rules of operation.
CAUTION!
A-frame top link and lower hitch holes in order to allow
your hitch pins to pass through them. A-frame should
be positioned square to the frame when tightening
hardware.
2. Attach rear blade hitch frame to tractor 3-point hitch
using a 3/4inch (Cat I) top link pin and linch pins
furnished by customer.
3. The moldboard, cutting edge, and moldboard frame
are a one piece weldment. Remove the hex nylock
locknut and flat washer from the one inch diameter
spindle bolt. Insert the bolt through the large hole at
the rear of the 3 pt. hitch frame. Slide the flat washer
on the spindle bolt and then re-install the one inch
hex nylock locknut. Only tighten until lightly snug (the
moldboard should be able to rotate by hand but have
little to no vertical movement).
NOTE: If the moldboard to hitch frame connection
becomes loose after blade use, this looseness can be
removed by tightening the one inch locknut.
Once the moldboard assembly is mounted to the 3 pt.
hitch frame, turn the moldboard assembly to your desired
operating angle and insert the angle adjustment shift pin.
NOTE:Always use the tractor anti-sway bars, blocks, or
chains to prevent blade side-sway. This is a must when
using the blade in a reverse position.
Your Rear Mounted Blade is now assembled and
mounted on your tractor. It is ready to go to work for
you.
1. Attach the upper 3-point A-frame members, to the 3point hitch lugs as shown on page 7, with hardware
as indicated. DO NOT tighten hardware. Align the

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!
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.
CAUTION!
OPERATION
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.
MAINTENANCE
1. Periodically check all bolts and tighten where
necessary.
2. Check the shift pin for excessive wear and replace if
necessary.
3. Repaint parts where paint is worn or scratched to
prevent rust.
4. Store rear blade in a clean, dry place.
