Safety -- It’s in your interest!
Safety Guidelines
Safety of the operator is one of our main concerns, however it is up to you, the opera-
tor to practice caution and safety!
To avoid personal injury, study the following precautions and insist that those working
with you follow them.
The M K Grader Blade is a very basic piece of equipment. Clear the area of people and espe-
cially children, as your attention will be concentrated on what the blade is doing, rather than
the surrounding space. Try to stay aware of your surroundings at all times!
When adjusting or replacing parts, do not place yourself or other persons or any part of your
body under a raised blade!
Replace any missing or illegible decals. Location of the decals are indicated elsewhere in this
manual.
Do not use the equipment while under the inuence of drugs or alcohol.
Review the safety instructions annually.
This equipment should not be operated by children, or those unfamiliar with the operation of
the M K Martin Grader Blade.
Do not allow persons to operate this equipment until they have read this manual and/or
were instructed by a qualied Person.
Do not paint over or deface any safety signs or warning decals on this equipment.
Please be careful with the extra weight on the back of the tractor. It may be necessary
to add extra weight to the front of the tractor to keep it balanced properly.

Operating
The 88 series blade is designed for Cat#1 3ph and is adaptable for “Quick Hitch”
The 98 series blade is designed for Cat#2 3ph and is adaptable for “Quick Hitch”
The M K Grader Blade has 5 manual pinned stops as standard angle adjustment, the blade
can be rotated180° with 5 more stops available.
Optional hydraulic angle adjustment is available to allow the operator to control the angle from
the tractor seat.
88 Series: To reverse the direction of the blade, unpin the cylinder at the front of the A frame
and turn the blade 180°, then pin the cylinder back on the other side of the A frame.
98 series: To reverse the blade, remove the hydraulic cylinder, rotate the blade 180°. Switch
the stand and cylinder bracket and install the cylinder in the new position.
Please note:
M K 88 series blade uses an 8” stroke agricultural cylinder (20 1/4” - 28 1/4” closed to open)
M K 98 series blade uses an 12” stroke cylinder (22 1/4” - 34 1/4” closed to open)
To operate the M K Grader Blade
1. Attach to tractor as any 3ph equipment.
2. Ensure all pins are secure
3. Raise the blade slightly.
4. Undo stand pin and pull the stand up to the top position and lock with pin.
5. At this time you can use the leveling adjustment and level the blade by adjusting the top
link. The blade should also be adjusted with the lower hitch adjuster until the blade is level
with the ground.
6. The blade can be made more or less aggressive by adjusting the top link. This changes the
cutting angle.
7. The blade can be rotated left or right depending on the direction that you prefer the material
to move.
8. For nishing the grade, allow the material to slip under the edge before it moves o󰀨 the end
of the blade.
This Grader Blade is not designed for excavating! Be careful when backing up as you can
now push the blade into the load causing some of the tractor weight to transfer to the blade
beam and may buckle it.

Care and Maintenance
After 1st 5 hours check all nuts and bolts and retighten if required. At 10 hours check all nuts
and bolts and re-tighten if required. Repeat at 5 hour intervals until all bolts have seated and
stay tight.
Storage of MK Grader Blade
Store MK Grader Blade in a rm, dry area, and set on blocks if the area is not rm enough to
support the equipment without sinking in. Clean o󰀨 all caked dirt and mud.
When storing for a long period and rusting may be a problem, unbolt swivel cap and apply oil
between the swivel shaft and swivel bushing, then replace the cap. This will prevent the mov-
able part from seizing up. Wipe all excess oil o󰀨 with a dry rag.
The Cutting Edge is reversible and after it shows considerable wear it can be reversed.
1 Loosen all the Plowbolts
2 Remove all bolts except the bolts at each end
3 Tilt the Grader Blade on its back and remove the remaining bolts.
Note! Cutting Edge is heavy! Handle with care and use heavy gloves!

These torques are for reference only. Not all these sizes and grades are necessarily used in this
machine. Bolts that are used as a pivot or hinge have to be used with a locknut, therefore only
tighten enough to secure the bolt and still allowing the part to rotate freely.
