Operation
1. Conditions of crops and field
Harvesting time of crops
The way to reap crops depends on the conditions of
crops and breadth of field.
Check them in advance to work efficiently.
It’s the time to harvest when most of grains and over a
half of the spike-stalk become yellow.
There will be more green rice-grain branches and less
harvest, and the total loss rate may exceed the national
standard if crops are reaped too early. On the other
hand, there will be more lodging, sprouting, broken
spike, cracked grains and loss if crops are harvested
too late.
Length of crops
The length of crops suitable for this combine harvester
is 30 to 150 cm.

[IMPORTANT]

If the harvesting height exceeds 70cm, the power
consumption will be increased and energy
efficiency be decreased; the threshing chamber
may be accumulated with dust, swing separator be
blocked, and threshing loss be increased, leading to
poor screening.

If the harvesting height is below 60cm, friction effect
in the threshing chamber will be impaired and grain
loss be increased. Put the chaff discharge adjust
lever to “Close” to reduce loss.

(11) Push the main shift lever forward to
start harvesting slowly
Reel height: To be lowered down as possible.
Reel height
Put the main shift lever to “Standard” or lower speed gears in

●
●
2- After the bag if filled with grain, close the discharging
gate and replace the bag.
[Precaution]
Check the volume of grain tank frequently during
operation. If the grain tank is excessively filled,
grain will block the outlet of lift conveyer to cause
blocking, burning of belt and other failures.
You may be rolled in the reel and
injured in the process of threshing by
feeding. So, be sure to follow the
instructions below.
A co-worker must sit in the operator
seat during operation so as to timely
stop the engine in case of
abnormality.
Roll up your cuff, and do not wear a
towel around your head, neck or waist
during operation.
The operator should stand diagonally
away from the reaping section and
feed crops gradually in small amount.
Chaff may pile up below the dust
exhauster hood during threshing by
feeding. Do not let the piled chaff
come into contact with the engine
exhaust pipe. Otherwise, fire hazard
may be caused.
Discharged straw and chaff may pile
up below the discharging section in
case of large-amount threshing while
the combine harvester is stopped. Fire
hazard may be caused by chaff in
contact with the outlet of engine
exhaust pipe. In this case, move the
machine or remove the piled chaff.

Main Factors
1) Crop variety easy to be
threshed (grains always
fall off when you grip the
spike tip)
2) Remaining lodged rice after
harvesting
1) Early harvesting, high
moisture content of rice
(over 26%)
2) High grain yield per unit
area (over 900kg per
100m2)
3) Rubber support behind the
swing separator is
improperly placed
4) Wind power of the fan is
too high
5) Openings in the chaff
sieves of the swing
separator are blocked
(under the circumstance
of wet rice)
6) Engine speed is too high
Remedy
1) Reel speed is relatively high, leading to more
threshing and high operating speed.
2) Adjust the reel height. (reel tine should not be in direct
contact with spike tip, but with spike root)
1) Move the reel forward, and pick up the lodged rice.
1) Wait for the appropriate time for harvesting.
2) Reduce the harvesting speed.
1) Reduce the harvesting speed or width as possible.
2) Put the chaff sieve clearance adjust lever to
“Open”.(as indicated in Page 50)
1) Move it upward. However, the end plate of the swing
separator plate may be affected and loss at the 3rd
outlet be increased if it is raised too much.
1) Reduce the wind power of fan. (turn the damper
properly to “Lower side”)
1) Remove the obstacles.
1) Operate at the specified engine speed.
1) Operating speed is too high
comparing to yield
1) Reduce the harvesting speed.
2) Openings in the concave
screen are blocked (under
the circumstance of wet
rice)
1) Crop variety hard to be
threshed (grains do not fall
off when you grip the
spike) (branch tension
over 150g)
2) Operating speed is too fast
comparing to yield

<Main causes of crawler damage>

Traveling/moving along steps or ridges

Traveling over bridge.

Traveling on roads with sharp bumps (steel bar,
stone etc.).
[Other precautions]

Operating temperature -20℃~55℃.

Chemicals, oil and salt in sea water may damage the track.

It is prohibited to climb up steps or cross deep ditches directly. Any steps or deep ditches should be leveled with
soil or wood.

It is prohibited to drive obliquely on a slope to prevent accidents caused by the crawler running off the rails.

It is prohibited to turn abruptly during traveling at a high speed. Otherwise, the crawler may fall off the rails and
cause accident.

It is prohibited to travel on roads in a long distance. Use a truck or other vehicles for long-distance traveling.

It is prohibited to use any ramp boards without anti-skid measures.

Check the crawler tension on a regular basis for timely adjustment. Otherwise, wear of the driving sprocket and
iron core of the track may be early.

Check the wear condition of driving sprocket, idler wheel and track roller, and replace when necessary to
prevent damage and crack of the crawler.

Try to avoid crossing the ridge or ditch during field operation, so as to prevent damage and crack of the crawler.

Timely remove the mud, straw and other foreign matters stuck in the crawler if any. Otherwise, the traveling
resistance may be increased.

Reducing the power may lead to crawler crack, inner side scratch and early wear of the driving sprocket.

The track must be correctly tensioned. It may run off the rails if it is tensioned too loosely, or break if tensioned
too tight. In case of abnormal wear of the driving sprocket, the crawler core may be drawn out and lead to
crawler damage, as shown below.
Wear condition of driving sprocket
[Note]
The driving sprocket should be replaced if the dimension measured by the calipers shown above is <20mm.
