Adjustments to the knives in big baler

-Know and explain the different knife drawer options
-
-Adjust the knife drawer to work in the field

-Change the knives in the knife drawer
1. Center the knives in the rotor
Loosen (2)             Adjust and center knifes 
  to rotor with (3)       tighten (2)
To centre the crop cutting knives, the locking plate of
the knife drawer can be adjusted.
2. Adjustment of knife frame latching hooks

retract cilinder                 loosen (4)
adjust X=1mm with (6)     tighten (4)
2.Adjustment of knife frame latching hooks.
Retract knife frame hydraulic cylinders completely. Adjust with eyebolt ref.6 a clearance   of X=1mm between latching hook ref.2 and latching plate ref.3. Adjustment to be made on both sides of the machine

3. Knife replacement
Lower the knife drawer hydraulically from  tractor
Slide open the knife drawer
Replace the knives – place false knives when knive is removed
Follow reverse way to close the drawer
remark : It is no longer necessary to unlock the knives.
 

4. Knive sharpening
Field test results indicate the knives can best be
resharpened after approximately 500 bales in clean
crop conditions. In contaminated crop conditions
resharpening may be necessary after 200 bales.
Grind on the smooth side of the knife only, never
on the notched side.
When reinstalling the knives, make sure they
regularly change position in the machine, i.e. middle
ones on the outside and vice versa, to equal out their
wear pattern

5. Knife drawers available

Crop flow adjustments in big baler

Covered in this chapter :
- principles of feeding (packer, packer cutter, rotor cutter)
- double knot principle
-Setup the sensor plates according to the machine type
-Adjust the stuffer
-Explain and adjust the stuffer brake
-Adjust the crop holding fingers to the correct settings
1. Sensor plates
2. Stuffer 
Before loosen the bolts to change the adjustment.
  Place vizegripe on sensor plate (under pre-chamber) to limit the
    sensor plate travel at the right spot.
  Adjust bracket  in the middle of the slotted holes and adjust 
    dimension Z =10mm by lengthening or shortening the linkage 1 .
TIC S’07 : accelerated stuffer (improve top fill)
                   reinforced shuttle pivot arm
                   revised lobe (less
agresive

3. Shuttle feeder               
4. Stuffer brake
It must be possible to clear clutch dog arm away from roller.
The brake spring length is initially set at 35 mm
(1 3/8’’). Check and adjust the brake as follows:
1. With the baler operating at normal speed, check
if the stuffermoves steadily and without abnormal
shocks.
2. Ensure that the stuffer returns and remains in the
home position. Observe the stuffer clutch after
making these adjustments and check if it is
possible to clear clutch dog arm (3) away from
roller (4) by hand.
Final adjustment:
After one hour working:
• the clutchmust not overheat. If it does, reducethe
spring setting by loosening adjusting nuts (2)
 half a turn.
• If the stuffer fork does not remain steady in the
home position, increase the spring setting by
tightening adjusting nuts (2)  half a turn.

5. Crop holding fingers
1. Pull crop holding fingers until rubber stops are touching charge chamber. At
    this point tips of crop holding fingers should be flush with front edge of slots in
    cross beam. If not adjust with shims at rubber stops.
2.Trip stuffer mechanism. The tips of the crop holding fingers should withdraw 0
    to MAX. 10 mm. If not adjust with rod.

3. Check if Y = =/- 10 mm. If not adjust by moving rubber stop.

Monitor in big baler part 5 5. Menu structure

A. Overview



B. Mainscreen 1 & 2
When you press the mainscreen 1 or 2 button 2x you enter the working mode.
As before, the icon of the baler will change in a load and a capacity indicator from the moment you exceed a PTO speed of 600 rev/min. 
On the top of the main screen you can see a number of icons which indicate which options are installed and/or active. You can have :
-An indication for greasing system
-An indicator for fans. Until 600 rpm you will see a cross through the symbol indicating that the fans are installed but not active
-An indication for maintenance that has to be done
-An indication for the position of the knives..
Each time the same : if an symbol pops up with a cross over it, it indicates that this particular option is installed but not active because some conditions havent been fullfilled.

To switch the automatic and manual mode, you can select the upper right button and you can change the density with the + or – buttons.

Depending the options which are installed, you can have a number of icons popping up in the menu structure at the right side.
 to switch your worklights on or off, for the flashlight on/off or if an electrical bale length system has been installed – a button to knot manually.
If one of these buttons are not visible, this indicates that the option is not set to installed in the machine setup screen. Adjust if necessary. 

C. Field settings
This menuitem is only visible when a electrical bale length kit is installed or when a moisture kit is installed AND in the machine setup page is set to installed.
In this screen, you can calibrate your bale length. In the first box you fill in your desired bale length. You make a few bales (preferrable at least 3) and measure these bales. Make an average of the length and fill this in in the second box. Your bale length system is now calibrated.
In the 3rd box, you can set a minimum moisture level which is acceptable during the work.
If the moisture drops under this value you will get an warning.
In the 3th box, you can set the maximum moisture level which is acceptable during the work. If the moisture exceeds this value, you will get an warning (Moisture too high).

With the On/Off button you can activate/deactivate the warnings. 

D. Memory page

When pressing 2x on the memory page, you enter it.
In the mainscreen, you have the overview of the saved memories.
The number of icons you see on the screen (such as uncut bales, cut bales, moisture, bale length) depends on the installed options and are not always visible.
On the field :
-With memory “0” selected, you give in a job name in the “job name” field and start baling.
-Each time a bale is dropped, the counter increases.
-At the completion of the field you can edit the number of bales (e.g. Subtract an open bale). This has to be done in memory “0”. All other memories will not be editable.
-You press the store button (disk in the right upper corner) and at that moment your active job is shifted to memory page 1. The data that was in memory 1 shifts to 2, 2 to 3 ...
-The memory “0” is reset to 0 and is ready for a next job.
In total we have a memory space of 20 places available. If you exceed that number, you loose your 21th data

E. Service interval
Pressing the service interval button 2x brings you in the service interval page.
With the button in the middle you can tell the system that your maintenance has been done. There is a button for the 10h, 50h, 100h, 250h and 2500 bales service interval. You can also see a counter which shows how many hours already passed since last service check.
With the buttons on the right, you can have a summary of dates and amount of total bales and hours when last service has been done

F. User settings

In the user settings menu, you can adapt some configurations. This screen is mainly for the driver and contains :
-Oiling interval (only visible when installed in the machine setup) can be changed to high, normal, low, test to meet the field conditions you are working in. This setting changes the waiting time between 2 oiling pulses.
-Greasing interval : same as for the oiling interval.
-Show warnings : enabling this function will give you a popup when a warning occurs
-Show service interval : enabling this function will give you a popup when service needs to be done.
-Sound enabled : enabling this function will enable the sound of the monitor. (on warnings) 

G. Machine setup
In the machine setup screen you can setup the configuration of your machine. Flashlight installed, moisture installed, pickup stop ...
Pay attention that not all parameters are changeable. To change a number of parameters you need to enter a dealer mode. 

H. Information
The information screen shows you some totals (bales and hours) of your baler. You can also find the serial number of your baler in this screen and also the machine type and cutter type are displayed. There are no changeable items in this screen. 

I. Active errors

Pressing 2x the active error button, a summary of the active errors are displayed.
Each error is represented by 3 things :
-An error code
-An indication of which sensor / output is malfunctioning
-A short description of what is happening (e.g. Line open, voltage too low ...)
You cannot delete the active errors. You can only use the up and down arrows to scroll the complete list. 
J. Error overview

In the error overview screen, you will have an summary of all errors which were and still are active. After each error there is a checkbox.
To delete : 2 possibilities :
-Select the wanted errors with the checkbox and press the delete button (2nd from top)
-Press the ‘delete all’ button (3rd from top) and all errors will be deleted.
-
Errors which are still active popup immediately back on the screen and have to be solved first.

K. Screen setup

To setup your workscreens, you can select a number of parameters in the screen setup pages. Screen setup 1 is for main screen 1, screen setup 2 for main screen 2.
The number of parameters in the list will depend again on the installed options. 

L. Diagnosis inputs
In this page you can see all inputs that come into the BCM. In this way you can diagnose a defect sensor, broken wire ...
For a number of sensors (mistie sensor and load sensor) you also have a calibration button which guides you through the calibrations.
The monitor does noet indicate the 5 zones any more but gives only an indication ‘high’, ‘low’, ‘defect’.
Voltage <5V : OK low
Voltage >6,5V : OK high
Voltage = 8V : disconnected
Voltage = 0V : shorted to ground
Voltage = 12V : shorted to 12V
