• The diagram shows the closed centre brake circuit - Both brake pedals must be depressed to operate front axle and air brakes. 

• If open centre hydraulic pump, there is only one brake line ( right side ) to trailer brake valve - The front axle and air brakes will be operated when the right hand brake pedal is depressed.

 الشكل عبارة عن دائرة فرامل مغلقة تجمع فيه ذراع الفرامل عند ضغطها بين الفرامل الأمامية وفرامل الهواء

عند فتح المضخة المنتصف  يفتح خط فرامل واحد لصمام الفرامل - ستعمل الفرامل الأمامية وفرامل الهواء عند الضغط على بدال الفرامل الأيمن

Bleeding of brake system (2 persons):

LHS:

• Open F1 and depress LHS pedal until oil flows out

• Close F1, build up pressure with pedal and keep pedal down

• Slighty open F1 allowing oil and air to escape

• When flow stops close F1 before releasing the pedal.

• Repeat until flow is free of air. Then do F2 and F3

•

Brake cylinders connection:

• Open F1 of RHS circuit, depress and hold RHS pedal

• depress and hold LHS pedal

• Close F1, release RHS pedal and then the LHS pedal

• Repeat until flow is free of air.

•

RHS:

• F1 already done

•Do F2 and F3 like the LHS

15. Working modes

A. Automatic mode

B. Manual mode

C. Emergency mode

Basic components in big baler part 13 14. Hydraulic components

A.Pump + reservoir

Reservoir : 4L

                  Ambra Hydrosystem 46HV

  Sight glass to check level

air filter

Pump :  driven from stuffer gearbox

Oil reservoir: capacity 4L (1 us gallon)

        total circuit capacity 10.8 L (2.8 US gallon)

        AMBRA HYDROSYSTEM 46HV (or 46 BIO-V or  46 BIO-S)

        Sight glass to check level

Air filter: change at every oil change, after 10000 bales or annualy

B. Filter + cooler

•Filter 

•blocked filter warning indicator

•Serpentine cools down the oil

C. Density valve

•PWM (pulse width modulation)

•In automatic mode operated by the BCM and monitor

•In the event of electronic failure, the valve can be adjusted manually using an Allen key.

•This directly adjusts the pressure in the density system allowing the user to continue working. 

•This (proportional)  valve is used to control the density:

• 3 possibilities:

Automatic bale density control: the plunger load sensor measures the load applied to the bale by the plunger and a processor adjusts the pressure in the hydraulic system.(screw open ; automatic mode selected)

Manual bale density control: operator sets the hydraulic pressure in the density system from the monitor.(screw open ; manual mode selected)

Manual override bale density control: Monitor not used. The adjustment screw on the density valve has to be adjusted manually.(max 160 bar)

Pressure gauge :

• Indicates pressure in density cylinders.

• Bar and psi reading

• can be used as pressure indicator in case electronic system fails

C. Density valve + pressure gauge

A gauge at the front of the baler displays actual hydraulic pressure in the density system.

A useful visual reference to help the operator during work and also allow work to continue in case of electric failure.

Silage  40 to   70   Hay  50 to   80  Straw  60 to 100    

D. Density cylinder

•2 density cylinders compress the bale

•Density adjustable through monitor and the BCM adjusts the hydraulic pressure to maintain the preset level.

•Large diameter density cylinders

•Lowered operating pressure, but improved and strengthened design of density door balancers

•Changed geometry of the bale chamber cross section for ideal force distribution giving less unwanted bale density fluctuations

•Improved stability of density control software.

E. Bale chute

•Standard the machine comes with a roller bale chute

•Raised hydraulically from the lever at the rear RHS of the baler.

•Second last roller is now also with bearings to prevent damage in the transport position

All units will standard come with roller bale chute

Second last roller with roller bearings (last roller was already with bearings)

Reinforced front frame of the roller baler chute

F. Control levers

Rear lever: bale chute open / close

Middle lever : full balechamber eject

Front lever: only last bale eject

•Pressure relief valve 165 bar

•Non return valve for operating auto steer.

F. Lockout autosteer, knive drawer

Open : Knifedrawer open/close

Closed : Knife in/out

Open : Floating rear axle

Closed : Fixed rear axle
(only steered tandem axle

Basic components in big baler part 11 12. Oiling & greasing

12. Oiling & greasing

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

• Integrated automatic oilier

• Doses controlled with an electrical motor commanded by BCM-VT.

•Do NOT put motor continuously ON. This will burn out the motor.

B. Grease pump

•Centralised greasing is standard

•Seven main distribution blocks, 80 grease points.

•An optional automatic centralised greasing system is available

•The greasing rate can be adjusted on the monitor

•The automatic greasing models maintain the manual grease nipples for additional greasing in very dusty conditions or to clear blocked lines

•Automatic greasing system = centralised greasing system with pump.

•Pressure up to 350 bar.
