B. Monitor options


No monitor and use the monitor of a VT tractor (e.g. Intelliview II or Intelliview II plus)

Infoview II monitor – Black and white monitor
Full Isobus 11783

Intelliview III monitor – Colour touch screen monitor
Full Isobus 11783

C. Rear view camera


With the IntelliviewTM III monitor, an optional cameral can be fitted to keep track of the baling process

Integrated automatic oilier
A.Oiler
An automatic central lubrication distribution system takes oil from the pump and provides a constant regulated oil supply to the drive chains
The fixed displacement system ensures that each chain receives the correct amount of lubrication
Doses controlled with an electrical motor commanded by BCM-VT.
Do NOT put motor continuously ON. This will burn out the motor

Basic components in big baler part 7 8. Knotter

8. Knotter
A.Knotter drive shaft + protection
Protected with shearbolt. (replace every 2500 bales)
Knotters are shaft driven from the stuffer gearbox
Knotter & driveline protection is provided by a shearbolt
Contains the sensor for PTO rpm control.
Sensor receives signal of crowngear inside gearbox (z = 68 ; n = 11/68)

C. Stack assembly

Knotters are not painted but treated with special black anodising for reliable knotter performance from 1st bale onwards.
Easy accessible through flip-up cover and removable side shields
A sensor (new position) on the guard will indicate to the operator that the guard is in the open position by displaying a warning message on the monitor

D. Twine finger

E. Knotter brake
Large diameter knotter brake disc offers a smoother quieter cycle, reduced knotter shearbolt breakages and reduced needle damage.
Function: - To keep constant load on needles during tying cycle.
                  - Help to hold needles in fix position.
                  - Prevent needles from overrunning.
Spring length 32 mm

Basic components in big baler part 5 6. Rotor

6. Rotor
improved rotor scraper design
= improved function & stronger design = fewer blockages and greater output
• teeth spacing reduced from 16.5mm to 11mm
= improved cut and greater efficiency
= reduced power consumption

Feeder opening on rotor cutter machines is wider than the bale
This wider opening helps to feed crop to the sides of the bale ensuring better filled bales
Rotor cutter BB9060 – 1000 mm wide
Rotor cutter BB9070/BB9080 – 1400 mm wide
Rotor turns at 86 rpm
The rotor tines are paired, with one shorter than the other to
  - help crop flow
  - prevent rotor blockages
Behind the rotor, scrapers maintain the rotor clean. 

• More durable scraper beam• Deep drawn feeder floor for smoother crop flow (instead of welded assy – rotor cutter units only)

B. Rotor cutout clutch

The  clutch needs greasing every 250 hrs

C. Knives
1. Standard knife                                                                            1. Rotor units
2. Straw knife
3. False knife
Hard faced knives as DIA

D. Knive drawer

0.8m rotor medium cut – 11 knives
0.8m rotor short cut option – 23 knives
1.2m rotor medium cut – 17 knives
1.2m rotor medium cut – 33 knives
Medium cut is sufficient for more than 80% of the customers.
When replacing knives, there is no longer need to unlock the knives. 

E. Knife protection

Basic components in big baler part3 4- feeding

4- FEEDING
A. Stuffer gearbox
Stuffer gearbox is driven by the LHS halfshaft from the main gearbox.
Goals of the stuffer gearbox :
- activate the stuffer
- drive the knotter gearbox
- drive the hydraulic pump for the density system.

Check the oil level with the glass
B. Stuffer + shearbolt
Is synchronised with plunger, stuffer gearbox and trip mechanism.
Protected with shearbolt and sensor.
The position of the pivot point of the stuffer has changed which delivers a gradual increasing speed of the stuffer and so a better top fill.
The shape of the stuffer bar changed from square to round. Also the dimension increased.
The stuffer teeth have a sawteeth shape which eliminates crop accumulation on the precompression chamber.
The routing of the greasing and sensor wiring loom changed to avoid that the lines are broken during the stuffing.
The material of the stuffer teeth  is hardox
C. Precompression chamber

“Fill flow kit “  improves “top filling” : standard on rotor units, option on packer cutter units
Stuffer trip sensor fingers repositioned (in centre of floor base) – no jamming with stones, giving improved crop flow and higher daily output
D. Crop holding fingers
These are driven from the RHS of the baler and will open when the stuffer is moving. Crop holding fingers and stuffer are mechanically linked. 
E. Sensor plates – Stuffer trip mechanism
Stop can be repositioned according press type
F. Sensor plates – Stuffer trip sensitivity

Controls the size of flakes injected into the bale chamber.
Lever in forth notch (from the rear) to start is ok for most conditions.
G. Stuffer brake

3 springs adjusted to 35 mm

Basic components in big baler part2 PICKUP

Basic components in big baler part2 PICKUP 
3. Pickup
A. Pickup width + slip clutch
Pickup width between 1.98m and 2.40m as type of big bler
Four bar pick up assembly.
Two centering augers.
Raised and lowered hydraulicaly from tractor (single working cilinder)
Optional: PU stop system on rotor units. If stuffer shearbolt fails a signal from BCM VT controls a solenoid. That solenoid blocks the PU at the RHS drive sprocket.
B. Slip clutch
Pickup slip clutch - Standard + packer machines set at 1000 Nm (earlier at 800 Nm) and for rotor machines at 1450 Nm.
This setting is not adjustable
Slip clutch needs burnishing each year.
Watch out with pickupstop for burned clutch plates.

C. Pickup floatation
Upper colar : set maximum height
Lower collar : adjust ground force. Adjust this one with special tool. 
1. Raise PU completely
2. Loose height setting collar and slide to right
3. Lower PU again
4. Insert special tool in 4 slots and behing force setting collar ring.
5. Relocate force setting ring as required
6. Raise PU again and place special tool back on its place.
7. Reinstall height setting collar.
D. Centring augers
Packer and packer cutter machines have the big undershot auger. undershot because the crop is pushed down as the auger turns.
Rotor machines have the small overshot auger. Overshot because the crop is lifted as the auger turns.
Centring augers run at 233 rpm

E. Pickup wheels
the minimum clearance should be 30 mm but in stony terrain it can be set at 50 to 80mm
The height of the pickup wheels can be set without a spanner. Just unleash the pin, change height and reattach the pin. (Like on combi '08)
remarks :
- possibility to mount a stone trap before the pickup so that projected stones cannot destroy the cab of the tractor. 

F. Tines
Standard and packer cutter pickup tines are springs,
Rotor cutter machines are more solid and ar mounted on rubber blocks.
Also check if the pickup tines are not bended
Also check if the pickup tines touch the pickup guards.
BB9050/BB9060 : 112 tines
BB9070/BB9080 : 128 tines or 136 tines on rotor cutter models
Pickup runs at 140 rpm

G. Pickup guards
Pickup guards are tightened at the bottom to allow crop, which entered the pickup, to evacuate. This was also the case in '07 '08 machines. Before we had crop accumulation in the pickup.
The pickup tines cannot touch the guards as the tines wear out and brake easily.
H. Windguard


Plate windguard
Holds crop firmly in contact with pick up tines.
Adjustable with single chain.
Tines bolted on.
Roller windguard also holds the crop in contact with the tines.
The roller windguard is not driven. This windguard is used in large volume straw crops where blockages can occur. 

A. Stuffer gearbox

Stuffer gearbox is driven by the LHS halfshaft from the main gearbox.
Goals of the stuffer gearbox :
- activate the stuffer
- drive the knotter gearbox
- drive the hydraulic pump for the density system.
Check the oil level with the glass
