Handling Instructions
Tightening torques
Standard tightening torques
Bolts and Nuts
A number of bolts are used in each part of this machine.
Be sure to re-tighten the bolts and nuts, because they may be loosened at the earlier stage of the
use.
As to the bolts and nuts without any special instruction, tighten them in appropriate tightening torque
with proper tool.
Too much tightening may cause the looseness or damage of the screw.
The strength of tightening is determined by types of screws, strength, the friction of thread face or
base face and others.
The table below is for the galvanized or parkerized bolts.
In case that the strength of internal thread is weak, it is not applied.
Do not use rusty or sand attached "screw."
Otherwise, it may cause insufficient tightening even if you apply the specified tightening torque.
The friction of the screw face becomes higher and the tightening torque is canceled out by the
friction, therefore sufficient tightening cannot be applied.
If "screw" is wet by water or oil, do not tighten it with normal tightening torque.
If the screw is wet, the torque coefficient will get smaller and it may result in too much tightening.
Too much tightening may cause looseness by the screw stretched or result in damage.
Do not use a bolt experienced too much burden.
Using the impact wrench requires the skill.
Do exercise as much as possible for steady tightening.

Handling Instructions
With the cutter adjustment nut, adjust the
3.
engagement between the reel cutter (cutting
cylinder) and the bed knife (bottom blade) so
that newspaper (one sheet) will be cleanly
cut by the edge of both blades when the
blades in their entirety come slightly into
contact with each other.
Insert a strip of newspaper into the space
4.
between the reel cutter (cutting cylinder) and
the bed knife (bottom blade) at an angle of
90 degrees. Then, rotate the reel cutter
(cutting cylinder) counter-clockwise (when
you face the mower unit from the left) to
check the sharpness of the blades.
Check the sharpness of the entire range (at
three or four points between the left and right
ends) of the reel cutter (cutting cylinder).
･
If there is a gap between the blade edges:
Loosen (rotate counter-clockwise) the
cutter adjustment nut to apply more
contact pressure between the reel cutter
(cutting cylinder) and the bed knife
(bottom blade).
･
If the reel cutter (cutting cylinder) is too
tight to turn:
Tighten (rotate clockwise) the cutter
adjustment nut to reduce the contact
pressure between the reel cutter (cutting
cylinder) and the bed knife (bottom blade).
･
If the blades still cannot cut well:
Perform back lapping of the reel cutter
(cutting cylinder).
Adjustment of Cutting Height
Adjust the cutting height to fit your cutting work.
This applies the set cutting height that differs
from the actual cutting height.
Cutting Height and Blade Thickness of Bed Knife (Bottom Blade)
The recommended minimum cutting heights
are based on those of common greens.
These values are affected by the conditions of
the greens and the machine specifications.
If the green undulation is hard, set it a little bit
higher in order not to damage the green
surface.
The recommended minimum cutting height
according to the blade thickness of the bed
knife (bottom blade) is as indicated below.

from the ground.
Allowing the front groomer to go into the
ground may damage the groomer shaft.
If the front groomer goes in too deep, the
engine and drive components may become
overloaded, which may cause malfunction and
damage.
When using the grooming brush, adjust it to
the same height as the cutting height.
If the grooming brush is too low, it may quickly
become damaged.
Set the slide caliper to the required cutting

Note:

(IGCA can be installed onto the LM18GC/
LM56GC.)
IGCA is located above the mower.
The IGCA is a mechanism that prevents the
mowing attitude of the mower from changing,
even when there is an increase in the volume
of clippings entering the grass catcher.
It eliminates as much as possible the transfer
of rough handle movements causing changes
in the mower's attitude.
Since the mower is stabilized while the lawn is
mowed, even if the handle is treated roughly,
the cutting height does not change from the
start of mowing the green to the end.
Stable lawn mowing work can be performed
regardless of the operator's skill level and
machine proficiency level, enabling all greens
to be mowed at a uniform cutting height.
The groomer clutch lever is located on the
upper side of the right frame and has three
positions.
When the lever is set to the "Normal " position,
the groomer rotates in the same direction as
the reel cutter (cutting cylinder).
When the lever is set to the "Reverse "
position, the groomer rotates in the opposite
direction as the reel cutter (cutting cylinder).
When the lever is set to the "Stop" position, the
groomer will not rotate.

The cutting height fluctuates due to the upand-down movements of the mower caused
by the weight of the grass catcher.
Solution:
The mower and grass catcher operate
independently.
Therefore, the mowing attitude of the
mower is not affected, even when the
grass catcher becomes heavier from the
added weight of grass, thatch, sand, etc.
The operator can mow at a uniform cutting
height from the start of mowing the green
to the end.

Issue 2:
The cutting height is uneven due to the upand-down movements of the mower caused
by the operator's handle movements.
Solution:
The grass catcher and handle are linked,
eliminating as much as possible the
transfer of rough handle movements
causing changes in the mower's attitude.
By adjusting the link rods, the handle can
remain centered in the handle adjuster,
and uniform mower contact pressure can
be achieved.
Effect 1:
Regardless of skill level, any operator can
mow at a uniform cutting height, as long as
the handle can be adjusted within the range
of the hole in the handle adjuster.
This is effective when accelerating very
quickly or mowing undulations.

Back Lapping of Reel Cutter (Cutting Cylinder)
Back lapping is work similar to sharpening a
cooking knife. If the edges of the reel cutter
(cutting cylinder) and the bed knife (bottom
blade) become blunt and make cutting difficult,
both the reel cutter (cutting cylinder) and the
bed knife (bottom blade) should be
simultaneously sharpened by reversing the reel
cutter (cutting cylinder) with an abrasive paste
applied.
However, back lapping is a temporary measure
and would not restore the sharpness
completely.
If the edges of the reel cutter (cutting cylinder)
and the bed knife (bottom blade) become blunt
and make cutting difficult, follow the steps
below to perform back lapping.
Both the reel cutter (cutting cylinder) and the
bed knife (bottom blade) are edged tools.
Handle them carefully, since they could cut
your hands and feet.
1 Newspaper
2 Back lapping powder
3 Gel compound
4 Brush
Note:
The mixing ratio for the abrasive, in volume,
is one part back lapping powder (#200 #400) to three or four parts oil.
Have a lapping machine or the lapping
2.
handle ready.
When handling the reel cutter (cutting
cylinder) or bed knife (bottom blade), wear
gloves to protect your hands.
However, pay attention not to let the reel
cutter (cutting cylinder) catch your gloves, etc.
Otherwise, you may injure your hand or
fingers.
Check the sharpness of the blade by checking
the blade engagement after cutting grass.
Maintenance
During back lapping, the reel cutter (cutting
cylinder) rotates.
Keep hands and feet away from moving parts.
Do not perform back lapping with any other
persons.
Have the following items ready: Strips of
1.
newspaper, Abrasive [Back lapping powder
mixed with oil; or gel compound (Baroness
genuine abrasive)], Brush.
Stop the engine.
3.
Set the traveling/working selector lever to the

Sharpening of Reel Cutter (Cutting Cylinder)
Both the reel cutter (cutting cylinder) and the
bed knife (bottom blade) are edged tools.
Handle them carefully, since they could cut
your hands and feet.
Wear gloves when touching edged tools to
avoid cutting your hands.
The sharpening of the reel cutter (cutting
cylinder) consists in maintaining its roundness
and creating a relief (second edge face).
This work should be performed if the
sharpness cannot be restored, even after back
lapping, or if the relief (second edge face) has
worn away.
Sharpen the reel cutter (cutting cylinder) when
the sharpness cannot be restored, even after
back lapping, or when the relief (second edge
face) has worn away, there is full contact or
back lapping takes too much time.
In addition, if the reel cutter (cutting cylinder)
becomes worn and its shape conical, perform
cylindrical grinding to return it to a cylindrical
shape.
Note:
The outer diameter of the reel cutter (cutting
cylinder) shaft is 25.4 mm.
