4.Features
This energy-saving type large mowing machine with a diesel engine is manufactured for
professional use especially for slope land operation. The mowing width is 154 or 170 cm,
and the maximum output is 26.5 kW. The machine is ideal for mowing on river banks,
skiing ground and major roads, as well as in other large areas.
The rubber crawler ensure great hill climbing ability, and the low center of gravity permits
safe work even on a slope. The crawler section is provided with a seesaw roller mechanism
to cope with pitching, and the projections inside the crawler are made long to prevent
crawlers from coming off. The grease cylinder used for crawler tension adjustment is easy
to operate.
The machine travels hydraulically at variable speed. The single traveling lever permits
simple operation to move the machine forward and backward, change the speed, and turn
the machine. The position of the traveling lever can be selected from five angles, ensuring
satisfactory operation and improvement of work efficiency.
The hydraulic system permits easy adjustment of mowing height. The special structure of
the knife frame permits long grass cutting length and easy collection of cut grass. The
grass stop shaft (option) makes the cutting length shorter.
The step (simple riding unit) keeps the machine horizontal by using an angle sensor so as to
enhance safety of the operator.
The hammer knives are attached to move freely and the structer lessens impact of stones
and other obstacles when they hit against the hammer knives, hardly causing damage to the
hammer knives.
The hammer knife is made of heat-treated special tough steel, ensuring sharp cutting and
durability and permitting use of both sides by changing the right and left knives. The
hammer knives are attached by bolts and nuts, permitting easy change.
The four-cylinder diesel engine with a starter is easy to start, and the forced lubrication
system and large oil pan can withstand the instantaneous maximum inclination of 35
degrees.
The hitch method is adopted to install the mower portion, permitting easy
installation/removal of the portion.

When driving the machine on a steep slope, the machine will not stop even if the traveling
lever is released. When driving the machine on a slope, hold the traveling lever with one
hand and the handle with the other hand so that the machine can stop any time. Never release
them during traveling.
The hydraulic method, in which a solenoid valve and cylinder are used, is adopted for
mowing height adjustment. Tilt the mowing height adjusting switch on the traveling lever to
your side to raise the mowing height, and tilt it forward to lower the mowing height. The
mowing height adjusting range is 3-30 cm. The knife rotation above the range is prohibited
for safety's sake though the mower portion itself can be raised higher for the sake of
transportation or storage. Adjust the mowing height appropriately. Adjust the mower portion
lowering speed with the valve unit, which will be seen at the back of the fuel filler port when
the right side cover is opened.
9-4. Mowing height adjustment
The working speed is hydraulic variable within the range of 0-6.5 km/h for forward operation
and 0-4.5 km/h for backward operation. Adjust the speed appropriately with the traveling
lever according to the condition of the geography and grass.

Knife clutch lever
Engage the knife clutch right before starting mowing operation. Be sure to leave it
disengaged during any operation other than mowing.
Since the knife shaft rotates by the centrifugal force, engage the clutch halfway until
the rotation is normal. Do not engage the clutch completely at a stroke.
CAUTION

The step is kept horizontal at all times by the angle sensor, automatic level control box and
electric cylinder. The "step control changeover switch" at the left side of the traveling lever
permits switching from AUTO to MANUAL, and vice versa. When the step control
changeover switch is in the "MANUAL" position, the "step control manual switch" under the
step control changeover switch permits control.
However, be sure to set the step control changeover switch in the "AUTO" position during
mowing. Use the manual position only when maintaining the machine, the automatic control
circuit fails, or some other emergency arises. When the automatic circuit fails, replace the
part with a new one immediately. Do not operate the machine for mowing on the manual
control step.
9-6. Step (simple riding unit)
9-7. Transportation on public roads
For transporting this machine through public roads, follow the appropriate laws of the
country where it is moved.
9-8. Alarm buzzer
When the alarm buzzer sounds, the engine is overheated. Stop operation, and remove dust
that is jamming in the radiator or air cleaner etc.
When the machine is not to be moved, pull the side brake lever fully to your side, and the
brake will be applied to the hydraulic motor and the traveling lever will be locked at the
neutral position.
When the balance is lost, the hammer knife will vibrate because it is rotating at high speed,
which is very dangerous. Exercise care sufficiently.
9-9. Side brake
10. Hammer knife
Both sides of the hammer knife are sharpened. When one side is worn, remove the pair
of knives, and attach them reversely. The knife is attached to the knife shaft mounting
10-1. Use of both sides of hammer knife
hitch section by 11 mounting pin 32 and the nut with disc washer, and the knife can be
removed easily.
Attach the mounting pin in the same direction as before.
The knife shaft assy is balanced when shipped from our factory; therefore, unless all the
knife blades of the same weight each are replaced at one time, or unless replaced
symmetrically on the right and left portions of the knife shaft, the weight balance may be
lost and vibration may be generated.
Since the hammer knife shaft assy are rotated at high speed, pay attention to the weight
balance when replacing the hammer knife.
10-2. Replacement of hammer knife
When both sides of the hammer knife blade are worn, grind each blade in a manner that
the weight of each blade will be the same as much as possible.
When the weight balance of the hammer knife shaft assy including the knife blades is
poor, the hammer knife shaft assy will generate vibration, breaking the machine.
10-3. Grinding the hammer knife
11-1. Operation on slope
When operating the machine on a slope, move the machine upward gradually from the
bottom of the slope along the contour line.
When operating the machine on a slope, push the traveling lever forward to move the
machine forward, pull it to your side to move the machine backward, and change the angle
of the traveling lever to change the speed. Turn the traveling lever in the direction, in
which the machine is to be turned. Release the traveling lever, and the lever will be set in
the neutral position, stopping the machine. For safety, stop the machine so that it will be
positioned along the contour line. When stopping the machine vertically on a slope, the
machine may not be able to stop immediately because of the inertia of the traveling
machine. The machine is provided with a hydraulic traveling system, and the step is
provided with an automatic level control sensor. When the machine is therefore turned
toward the bottom of the slope, the machine will turn smoothly because the center of
gravity of the machine changes favorably, also ensuring the operator since this way can
avoid his position just below the machine during turn.

CAUTION
CAUTION

11-2. Precautions as to operation on a steep slope
Be sure to observe the following matters when using the machine on a
steep slope of 20 degrees and above.
Do not operate the machine when there is a risk of falling or slipping.
Before starting operation on a steep slope, check for holes, rocks, tree roots, illegal
throwaways, etc. Remove them, if any, and then carefully operate the machine.
On a steep slope, operate the machine along the contour line, and turn the machine in a
place with a small angle of inclination as much as possible.
Do not operate the machine on a steep slope of 30 degrees and above. Since the
machine is very likely to fall down sideways on such a steep slope.
When ropes are used on a steep slope while working together with an assistant worker,
the machine may move to a very steep slope with an angle of inclination that exceeds
the allowable angle and the risk of falling down sideways will increase, preventing
safe operation. As a maker of the machine, we will prohibit such operation.
12-1. Precautions as to maintenance
12. Precautions as to maintenance
Thoroughly understand the method of required maintenance.
Do maintenance in a dry, clean place.

Replace worn or damaged parts.
Do not remodel the machine. Use genuine parts for maintenance to ensure safety.
Remove dust, grease, and oil adhering to the machine.
Remove the minus (-) wiring from the battery before maintaining the electric system.
12-2. Prevention of damage due to high-pressure oil
The high-pressure oil, when sprayed over the skin, will cause serious injury.
Release the pressure before removing the high-pressure line, hose, and joints.
Check the tightness of all joints before starting operation.
Use a small piece of cardboard to check for leakage. When your skin is sprayed with high-
pressure oil, you must see a doctor within two to three hours.
12-3. (Diesel fuel) Precautions as to fuel handling
Use of fire is prohibited strictly during fuel supply.
Stop the engine to cool it outdoors before supplying fuel.
To prevent fire, keep the machine clean without dust, grease, or oil at all times.
Wipe off spilt fuel cleanly.
Refer to the battery instruction manual for the method of handling the battery.
12-4. Precautions as to battery handling
Use of fire is prohibited strictly when checking or charging the battery. The electrolyte is
dilute sulfuric acid. Do not allow it to contact your body or the machine. If the electrolyte
adheres to your body or the machine, wash it off with water immediately. Especially when
it enters your eyes or you swallow it by mistake, see a doctor immediately.
When removing the cable from the battery, remove the negative side first, and when
attaching the cable to the battery, attach the positive side first. When the sequence is
reversed, tools may touch the machine and cause a short circuit, generating sparks.
Connect the battery cables correctly to the positive and negative sides. If the direction of
connection is wrong, the battery and its electric equipment will be damaged.

16-3. Confirmation after adjustment
Stop the engine and move the respective levers to check for interference.
Check that the machine is in the neutral position and will not move even if the engine is in
the full-throttle state.
(When the side brake lever is pulled and returned)
After moving the traveling lever to move the machine, release the traveling lever, and
check that the machine will not move.
After the above-mentioned adjustment, confirm the following:
17. Engine
(Diesel fuel) Precautions as to handling of engine
a) Use diesel fuel as the engine fuel.
b) The machine is to be operated under severe conditions such as vibration, slopes, and dust.
Change the entire engine oil 10 hours after the initial operation. Then while continuing
inspection and replenishment before use, change the entire quantity every 50 hours
thereafter.
Change all the oil filters simultaneously as well.
When using the machine in a dusty place, change oil and the oil filters more frequently.
The quantity of the engine oil is 7.9 liters. Use the diesel engine oil in the service class CC
or above specified by the API standard.
c) When air is sucked in the fuel system of a diesel engine, the engine will not be started.
Inspect and maintain the diesel engine at all times to prevent entry of air into the fuel
system. Operation will be difficult when the fuel filter and electromagnetic pump filter are
clogged with dust or when water remains in them. Drain water or clean filters every 50
hours. Replace filters with new ones every 200 hours.
d) Cover the suction port of the air cleaner with polyurethane and cleaner cover at all times
during operation. Be sure to clean the air cleaner element before operation, and replace
the element with a new one every 200 hours.
e) Mix antiseptics (long-life coolant) into water, and put the mixture in the reserve tank up to
the MAX position as a radiator cooling water. Change the cooling water every 50 hours.
Check and supply the cooling water before operation. When the temperature is likely to
drop below the freezing point, use an antifreeze mixture. When the radiator fins are
clogged with dust, blow air to clean them.
Refer to the diesel engine operation manual for the method of handling the
engine.
There is a risk of a skin burn. Do not open the radiator cap during or right after
operation.
18. Hoisting
Precautions as to hoisting
a) Qualification necessary to use a crane to hoist the machine
For hoisting the machine, follow the appropriate laws of the country where it is hoisted.
b) Hoisting procedure
Lower the mower portion until it touches the ground.
Pull out the four hoisting hooks and secure them with pins. Hook the wire ropes
completely with shackles. Use wire ropes with sufficient strength. Be sure to use four
ropes of 2.5 m or more in length.
Pay attention to the position of the center of gravity during hoisting to balance the
machine sufficiently. Do not approach the machine inadvertently during hoisting.

19. Attaching/detaching the mower portion
Be sure to install and remove the mower portion in a flat horizontal place. Stop the
engine unless it is necessary to move the attachment mounting base up and down or
to move the machine forward and backward.
19-1. Removal of attachment
(The numbers in [ ] in the text correspond to the parts catalog Nos.)
Remove the intermediate shaft belt cover [17-44] and right crawler cover [6-47], and then
remove the belt [7-30] that connects the machine and the mower portion.
Remove the clip pin [6-75] and remove the lock pin [6-74].
Set the cylinder single-/double-acting changeover switch [12-40] in the "double-acting"
position, and lower the attachment mounting base.
After confirming that the hitch sections are separated, slowly move the machine
backward, and the operation is complete.

19-2. Installation of the mower portion
(The numbers in [ ] in the text correspond to the parts catalog Nos.)
While engaging the hitch sections, slowly move the machine forward, and raise the
attachment mounting base to engage the hitch sections.
After confirming that the hitch sections are engaged completely, attach the lock pin [6-74]
and secure it with the clip pin [6-75].
Set the cylinder single-/double-acting changeover switch [12-40] in the "single-acting"
position.
After attaching the belt [7-30] and adjusting the tension, attach the right crawler cover [6-
47] and intermediate shaft belt cover [17-44], and the operation is complete.
19-3. Hydraulic cylinder single-/double-acting changeover
Before starting ordinary operation, be sure to set the cylinder single-/double-acting
changeover switch in the "single-acting" position, and change it to the "double-acting"
position before installing or removing the mower portion.
Operation with the changeover switch in the "double-acting" position will cause the
hitch sections to be subjected to a load when the machine climbs over a large stone
or some other obstacle, causing machine failure.
20. Gear oil change for traveling motor
The speed reducer of the hydraulic motor for traveling is filled with 0.35 litter of gear
oil. Flush the speed reducer 50 hours after initial operation and every 200 hours after
that, and after each flushing, fill the speed reducer with a new gear oil(ISO VG140).
Unless the oil is changed according to the specified time, the motor failure will result.
Be sure to change oil as specified.
