Harvesting in a broad field

 

For a broad field, the method of middle harvesting is 
suggested to improve the harvesting efficiency. 
 

 

 

 

3. Preparation before harvesting 

 

 

The Reaping section, conveying chain, cutters, 
threshing section, drive belt and other moving 
parts may cause accident or personal injury 
during cleaning and checking. Therefore, 
make sure to turn off the engine and engage 
the brake pedal lock before cleaning and 
checking.

 

 

Cutter and chain oiling

 

 

 

Be sure to turn off the engine before oiling the 
moving parts, or personal injury may be 
caused. Add oil to cutters and chains before 
operation and every 2 hours during operation. 

 

 

 

 

 

 

 

Auxiliary assist grain deck and grain 

bag

 

 

 

The auxiliary assist grain deck can bear the 
maximum load of 180kg. If overloaded, the 
deck may break and cause personal injuries. 
Do not pile any filled grain bags on it. 

 
1- Raise the auxiliary receiving platform to the operating 

position. 

 

2- Hang 20-30 bags on the fixed hooks. 
3- Mount 1 sack on each outlet. 
4- Open the grain discharging shutter.

4. Harvesting 

 

Moving in and out of the field

 

 

 



  Use the  “Forward” gear for 

ascending and  “Reverse” for 
descending a steep slope, and drive 
slowly. Otherwise, the machine may 
fall over. 
Set the range shift lever to “Low” and 
main shift lever to “1” to cross 
straightly the ridge. 



  Use the ramp boards if the ridge is 

over 10cm high. 

 

Harvesting by the ridge

 

 
Harvest manually within the areas 30cm from the ridge. 

 

Pay attention to the crops not harvested near the ditch 
and outside the track. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

Order of operation

 

 

(1) Adjusting the swing separator pieces

 

The swing separator is used to separate grains from 
chaff after threshing. Adjust the angle of chaff sieves of 
the screen according to the crop variety and threshing 
condition. 
 
1- Remove the left rear cover of the threshing section. 
2- Unfasten two bolts to take down the cover plate of 

swing separator. 

 

 

 
3- Turn the chaff sieve clearance adjust lever to change 

the angle of chaff sieves.

[Reference] 
Adjust the lever to “Standard” when delivery. 
 
4- Replace the cover plate after adjustment.

(2) Adjusting the screening air volume

 

 

 

Loosen the fixing bolt and move the damper up and 
down to adjust the air volume. Remove the damper in 
case of poor screening. 
Close the damper in case of much back loss. 
If light grain is still a loss from the back side of the 
machine even when the damper is completely closed, 
attach the winnower shutter (accessory) and decrease 
the screening air volume. 
 
 

(3) Adjusting the end plate of swing 

separator up and down 

 

 

Loosen the 4 fixing bolts at the end of swing separator 
to move the adjustment plate up and down. Move the 
plate upward in case of much scattering at the rear of 
the machine, or downward in case of poor screening. 
 
 
 

 

(4) Put the range shift lever to “Standard”, 

“Low” or “High” according to the 
condition of crop. 

 

 

 

(5) Use the accelerator lever to adjust the 

engine speed to the point that 
tachometer hand falls in the “Green 
Zone” of tachometer. 

 

 

[Precaution] 
Threshing may be incomplete and low in efficiency, and 
the threshing section may be blocked if the engine speed 
is below the rated level. The percentage of broken grain 
may rise if the engine speed is too high. 
 

(6) Put the threshing clutch lever and 

header clutch lever to “ON”.

(7) Operate the main shift lever to lower 

down the header to prevent missing 
any rice spike during harvesting.

 

 

 

 

 

(8) Adjust the reel by height control switch 

the lift button to ensure that the reel 
tines touch the stalk below spike when 
cutting, and the reel is in the position 
available for gripping crops. 

 

 

 
 

 

 

 

 

 

 

 

(9) The reel can be flexibly adjusted 

forward and backward by changing the 
position of pin hole.
