GENERAL INFORMATION

Bale Formation Overview [25786363]

Bale makeup

The baler is designed to make cylindrically shaped bales

not exceeding 800 kg (1763.7 lb) composed of 3 distinct

layers of varying density.

Level 1, the outer crop layer, is the most dense, providing

good weathering characteristics to the bale.

Level 2 consists of higher density layers, without damage

to the crop.

Level 3 is a low density core, allowing the crop to breath.

The thickness of these layers compared to each other will

be altered by changing the overall full bale density.

ZIL10FCRB001AAA

The quality of the bale is wholly dependent upon many

variables, including the type and variety of crop, how the

crop was prepared, size and shape of the windrow, mois-

ture content, feeding rate and the operator driving tech-

nique, and selected bale density.

NOTE: The thickness of these layers compared to each

other will be altered also by changing the overall full bale

density on the monitor in the tractor.

Windrow size - Feeding the windrow - Bale

formation

Windrow size

Good, uniform bales are made by feeding either full bale

chamber width windrows of 110 - 130 cm (43.3 - 51.2 in),

or narrow windrows of half or less the chamber width, 70

cm (27.6 in) or less. Avoid medium sized windrows of 80

- 100 cm (31.5 - 39.4 in), which are between half and full

chamber width. As the operator crosses this size windrow

to alternately feed material into the side ends of the bale,

material is continuously fed into the centre of the bale.

This will result in barrel-shaped bales. On the other hand,

oversized windrows of more than 140 cm (55.1 in) wide

will increase the risk of blockages in the pickup.

In order to avoid crop losses and ensure good bale forma-

tion, try to obtain flat, even windrows of 0.3 - 0.4 m (11.81

- 15.75 in) high. This will result in higher density, lower

power consumption and better conservation characteris-

tics, compared to high irregular windrows.

General operating tips

•

For good bale starts, reduce the forward speed at

the beginning of bale formation.

•

For well shaped and dense bales, reduce the for-

ward speed near completion of bale formation. This

will allow some relaxation time for the incoming crop

to be well compressed, resulting in a tight, water-

proof outer layer with good conservation character-

istics.

•

Prevent stones, boards or other foreign materials

from entering the baler to avoid damage to the ma-

chine components.

•

Do not backup the baler over the windrow to prevent

material from being wedged between the floor roll

and the pickup frame.

•

Avoid driving the pickup wheels over the windrow

(especially when baling on the headlands), as this

may cause blockages and wrapping around the

pickup wheels and centering augers, as well as

between the pickup side sheets and the windguard.

•

On wide pickup models, keep in mind that the pickup

centering augers only serve to take up irregularities

in the windrow. So, when feeding the sides of the

bale chamber, do not drive on the augers to avoid

blockages in this area.

6 - 4

6 - WORKING OPERATIONS

Feeding the windrow

Full bale chamber width windrows

120 - 140 cm (47.2 - 55.1 in).

Full width windrows are desirable since no weaving or

crossing the windrow is needed. The windrow should be

even and rather flat, without too much of a crown in the

middle, as this will result in barrel shaped bales.

Drive straight over the centre of the windrow to obtain

well-shaped cylindrical bales with properly filled and

dense bale ends.

Narrow windrows

60 - 70 cm (23.6 - 27.6 in).

When baling narrow windrows, start bale formation in the

centre to enable rotation of the bale during its formation.

Then start feeding the left and right side of the bale cham-

ber alternately by running 6 - 8 s on one side, then cross-

ing over to the other side for another 6 - 8 s and so forth,

Figure 2. Watch the bale density indicators during bale

formation to correct the weaving pattern, if needed.

When the bale is near completion, feed the windrow in the

middle of the pickup before stopping the forward motion.

ZIL10FCRB814AAA

Do not weave continuously as shown in Figure 3. If the

left/right shifting is too frequent, the ejected bale will be

barrel-shaped, causing stability (twine end wraps falling

off), transport and stacking problems. Furthermore, bar-

rel-shaped bales put high loads on the middle of the con-

veyor bars and on the chain, and increased wear or even

damage may result.

Medium-sized windrows

80 - 100 cm (31.5 - 39.4 in).

Avoid medium sized windrows! When crossing these

windrows to fill the other side of the bale, material is con-

ZIL10FCRB815AAA

tinuously fed to the centre. At the end of bale formation,

more material will be fed in the centre of the bale resulting

in barrel-shaped bales (Figure 3), causing stability (twine

end wraps falling off), transport and stacking problems.

Furthermore, barrel-shaped bales put high loads on the

middle of the conveyor bars and on the chain rollers, and

increased wear or even damage may result.

Oversized Windrows: Wider than 140 cm (55.1 in).

Too wide a windrow may lead to blockages at the pickup

sheets, the pickup centering augers and the feeder area,

as well as to problems with bale ejection.

Pickup height

On machines fitted with the accessory pickup gauge

wheels, adjust the gauge wheels with bolts (2) to obtain a

minimum pickup tine to ground clearance of 30 mm (1.2

in). Increase the pickup height in stony or uneven field

conditions.

Adjust suspension chain (1) with a little slack.

In extremely rough or high stubble conditions, it is even

recommended to work with the pickup wheels off the

ground. Lift the pickup completely and adjust the pickup

height as explained below.

On machines without gauge wheels, adjust the pickup

height with chain (1). To change the pickup height, grab

the handle (3) (Figure 1) and lift the pickup manually to

relocate the chain in the notch (1), Figure 1.

On machines equipped with the pickup hydraulic lift fea-

ture, the pickup can be lifted with the tractor hydraulics to

adjust chain (1). For road transport, lift the pickup com-

pletely and engage the chain as high as possible. Then

lower the pickup hydraulically and place the valve lever in

the neutral position.

(1.2 in). Adjust the ground clearance as described for the

standard pickup.

ZIL10FCRB786AAA

Pickup fixed height position

For special conditions such as rough straw fields, the

pickup flotation linkage provides the possibility to work

Baler Preparation [31337303]

Check that the twine tubes, net knife is in the home po-

sition, that the pickup is lowered and that the tailgate is

latched.

Set the throttle at half speed.

Turn on the PTO.

The lower starting speed will reduce the chance of shear-

ing the driveline shearbolt, on some units, and reduce

peak loads on the driveline.

Increase the throttle to the rated speed.

Do not operate at more than the rated speed, less will

save wear on the baler.

ATTENTION: Do not allow stones, boards or other foreign

material to enter the baler. Damage to the baler may re-

sult.

Do not back over windrows. Crop could become wedged

between the pickup frame and the floor roll.

Driveline protection [25789250]

NOTE: The PTO Driveline protection on this baler varies

between the pickup fitted and or optional Cut out clutch

1. Wide angle with optional cut-out clutch 1300 N·m

2. Single joint PTO with shearbolt 1100 N·m

3. Wide angle PTO with shearbolt 1100 N·m

Where the baler driveline is protected from overload and

damage by a shearbolt (1) in the PTO driveline, and the

shearbolt breaks, the power transmission from the tractor

to the baler will be interrupted and the machine will start

bulldozing the crop in front of the pickup.

Then proceed as follows:

6 - WORKING OPERATIONS

PTO cut out clutch (Optional)

A two cam-type cut-out clutch in the PTO drive shaft, just

in front of the gearbox in the cross beam of the baler,

protects the driveline and the baler from overload.

The clutch is factory-set at 1300 N (292.3 lb) torque and

does not require adjustment or maintenance.

In case of overload, the clutch will automatically break

loose and stop driving the baler.

A noise will be heard, the baler will stop operating and

start bull dozing the windrow in front of the pickup.

This will mostly happen when a big lump is fed into the ma-

ZIL10FCRB055AAA

chine at the end of the bale formation process. Too high

setting increases the chance of overloading the clutch.

When the clutch breaks loose proceed as follows:

Stop tractor forward motion immediately and re-

verse for a few metres.

Shut off the tractor PTO completely this will reset the

cut-out clutch.

Reduce the engine speed to somewhere just above

engine low idle speed.

Reengage the tractor PTO (at low engine speed) in

a start stop manner, trying to clear the blockage.

Normally the blockage will clear itself after a few

attempts. Increase the PTO speed back to 540 RPM

and continue baling.

NOTICE: In case of heavy blockages (ex stones) the

clutch may not fully reengage and continue hammering

or the tractor may shut down. Do not continue to run

the baler like this as fast wear or even damage to the

driveline may result.

The twine storage box can carry up to 6 balls of twine,

depending on twine ball size:

•

4 balls of 285 mm (11.2 in) diameter

•

5 balls of 270 mm (10.6 in) diameter

•

6 balls of 225 mm (8.9 in) diameter

ZIL10FCRB777AAA

Open the front upper access door and place 2 to 6 twine

balls in the storage box, as shown in Figure 1.

If 6 balls are used, tie the inside end of each outer ball C

directly to the outside end of ball B. Tie the inside end of

ball B to the outside end of ball A, after routing it through

the metal eyelet (1) in the twine box roof. Tie the twine

tails together with a small square knot and cut off the tails

of this knot.

Twine ball divider plates (2) assist in keeping the twine

balls in place. They can be removed and relocated in

other holes to hold 6 or 5 twine balls in place. When 4

balls of 285 mm (11.2 in) are used, only the middle divider

plate can be used.

Figure 3 (only 2 balls are installed for clarity)

Route the end of each twine ball through their respective

eyelet (1), through the twine tensioner (2) and through the

porcelain guide (8).

Then wrap the twine around the twine pattern pulley (3),

route it through the eyelet (7), in between both feed rolls

(6) and through the eyelet (5): the last part of this proce-

dure is made easier by the possibility of turning the rolls

(6) upwards, after shifting the threaded rod (4) forwards.

Leave a tail of about 15 - 20 cm.

NOTE: The pattern pulley has 6 twine grooves with 3 dif-

ferent diameters, 2 grooves per diameter. It is very im-

portant to always wrap both twines around the same di-

ameter, but using different grooves. When wrapping the

twines around the pattern pulley, make sure the left and

right twines do not cross each other (risk of entangle-

ment). After having routed the twines correctly, take up

slack in the twine routing between the twine tensioners

and the feed rolls.

ZIL10FCRB778AAA

Number of twine wraps

The pattern pulley has a double twine groove at 3 different

diameters.

The larger the twine groove diameter, the higher the num-

ber of wraps that will be placed around the bale.

The smaller the diameter, the lower the number of twine

wraps that will be placed around the bale.

Every groove roughly corresponds with a certain number

of twine wraps:

•

Small diameter groove = 14 wraps

•

Middle diameter groove = 18 wraps

ZIL10FCRB832AAA

•

Large diameter groove = 22 wraps

NOTE: The specified number of wraps only serves as a

guidance. The real number of wraps will be determined

by the amount of slip of the twines on the pattern pulley.

This depends on a number of external factors such as

temperature, type of twine used and twine tension.

The number of wraps is independent of the PTO speed

during wrapping, as the wrap cycle is driven by the running

twines. Altering the PTO speed during wrapping will only

change the duration of the wrap cycle. Therefore, it is

advised to keep the PTO speed at 540 RPM.

TWINE PLACEMENT

To control twine placement at the bale's edges, adjustable

twine stops (1) can be relocated in 4 different positions.

This requires the use of a spanner.

6 - WORKING OPERATIONS

TWINE WRAPPING PROCESS

After a bale has been formed in the bale chamber

the full bale alarm will sound (optional). Engage the

wrapping cycle manually (using the starting cord) or

electrically (from the control box) and stop the tractor

forward motion.

DO NOT DISENGAGE THE PTO

Once the twine has been picked up by the rotating

bale:

Release the Starting cord or

Action the Wrapper switch.

From now on, the wrap cycle runs completely auto-

matically.

Watch the spreader hooks move to the middle to

pick up the running twines. Then they will move

to the outside, lay the end wraps, change direction

and move to the middle again where the twines will

be cut by the twine knives. During the wrap cycle,

watch for rotation of the pattern pulley and proper

guidance of the running twine.

NOTE: If a twine is not picked up by the bale or by

one of the spreader hooks, the bale will be wrapped

only on one side. Do not eject the bale, but proceed

as follows:

WARNING

Entanglement hazard!

Disengage the Power Take-Off (PTO), turn off

the engine, and remove the key. Wait for all

movement to stop before leaving the opera-

tor's position. Never adjust, lubricate, clean,

or unplug machine with the engine running.

Failure to comply could result in death or se-

rious injury.

W0227A

A. Leave the tractor and cut the twines manually.

B. Remove the twines from the pattern pulley and

rotate the pulley manually and COUNTER CLOCK-

WISE to finish the cycle and bring the spreader

hooks back to the home position (spreader hooks

moving to the middle as the twine starts running).

ALWAYS rotate the pulley counter-clockwise.

C. Reroute the twines as described in "Loading twine".

D. Get back in the tractor. Restart the tractor, reengage

the PTO and restart the wrap cycle while feeding a

little crop into the pickup.

6 - WORKING OPERATIONS

When wrapping is finished and the twines are cut,

the pattern pulley will stop turning.

Open the tailgate to eject the bale. Do not disen-

gage the PTO

Close and latch the tailgate. Watch the density in-

dicators fall back to "zero" density. On machines

equipped with the electric control box system (stan-

dard on wide pickup models, accessory on standard

pickup models), a short "beep" will be heard as the

tailgate latches.

Check the result for bale density and wrap pattern.

If the wrap pattern is not acceptable, change the

pattern on the pulley, or change the placement of the

end wraps by relocating the twine stops. Continue

baling.

Twine Installation [25789153]

Twine wrapping

In extreme conditions, such as very dry and slippery straw,

the twine tails may have difficulties to start on the bale. In

these conditions, do not stop immediately at the "full bale"

signal (visual or audible), but keep feeding the windrow at

reduced forward speed until the twines are picked up by

the bale. Watch the start of both twines which is visible

through the front guard. Then stop immediately to let the

entire wrap cycle take place.

Too much twine tension will cause the twine to depress

into the bale and may result in excess spoilage in those

areas. In this case, release the tension on the twine ten-

sioners (1).

6 - WORKING OPERATIONS

Bale shape

The final bale shape is completely controlled by the op-

erator. Feeding the material as specified previously will

reduce the number of odd-shaped bales. Barrel-shaped

bales result when too much material is fed into the centre

of the bale. Cone-shaped bales will result if less material

is placed on one side of the bale, compared to the other

side.

In both cases, a bale is produced with poor handling and

weathering characteristics. Certain areas on the bale will

not be dense enough to keep rain and snow from penetrat-

ing deep into the bale. Learn to feed the material equally

into both ends of the bale.

To make tight weather-resistant bales, feed the material at

a rate which allows the bale to pack uniformly. Weave on

the windrow as necessary to fill the ends of the bale. Wrap

the bale with a sufficient number of wraps to maintain bale

integrity after ejection.

Bale Storage

When storing bales outside, place the bales in an area

which is higher than the surrounding ground level, rela-

tively dry, with ample sun exposure and air movement.

Allow 0.6 - 1.0 m (23.62 - 39.37 in) space on all sides of

the bale for air movement. Place the bales so prevailing

winds blow against the round portion of the bale and not

the ends.

Bales may also be stored in rows end to end, with 0.6 -

1.0 m (23.62 - 39.37 in) between rows.

6 - 22

6 - WORKING OPERATIONS

Bale ejection [30275497]

Bale ejection

When the twine wrap cycle is finished, the pattern pulley

will stop turning as the twines are cut. At this time, operate

the tractor hydraulics to open the tailgate and eject the

bale.

The bale ejector (1) (accessory) rolls the bale out of the

bale chamber far enough to allow closing of the tailgate

without having to move the tractor forward.

If the bale does not roll far enough to allow the tailgate

to be closed, increase the tension on the bale ejector

springs. If the bale rolls too far, which may result in un-

rolling of the twines, then decrease the tension on the bale

ejector springs.

ZIL10FCRB118AAA

For machines not equipped with a bale ejector, back up

the tractor a few metres prior to bale ejection. After eject-

ing the bale, move the tractor forward again, thus prevent-

ing the tailgate from closing on the ejected bale.

ATTENTION: Never eject or store round bales where they

could roll downhill. Make sure the handling equipment will

not upset and will hold the bales in all operating condi-

tions.

In extreme cases (e.g. bale sticking in the bale chamber),

it may be necessary to:

•

Investigate if the tractor has sufficient hydraulic

power to open the tailgate quickly enough.

•

Decrease full bale density.

•

Install extra wedging plates (1) underneath the ex-

isting plates left and right inside the tailgate (Figure

2).

Close and latch the tailgate and watch the density indica-

tors fall back to "zero" density.

ZIL10FCRB781AAA

On machines equipped with the electric control box sys-

tem (optional), a short "beep" will be heard as the tailgate

latches.
