Actual front axle load
The actual front axle load can be determined by:
•weighing.
•calculation:
The actual front axle load may never exceed the maximum
permissible front axle load.
The actual front axle load may never be less than the minimum front
axle load (M). In case the minimum front axle load (M) is not
mentioned in the tractor manual, the minimum front axle load (M) has
to be at least 20% of the unladen tractor mass (A).
In case the minimum front axle load is not met, you have to add front
ballast.
To calculate the minimum required front ballast:
Attention:
In case front ballast is mounted directly at the tractor, replace “F + G”
in the formula by the “Distance from the centre point of the front axle
to the gravity point of the ballast”.
Always check the maximum permissible mass, permissible axle load
and permissible tractor tyre load after mounting front ballast.
Actual rear axle load
The actual rear axle load can be determined by:
•weighing.
•calculation:
The actual rear axle load may never exceed the maximum permissible
rear axle load.
The actual rear axle load may never be less than the minimum rear
axle load (N). In case the minimum rear axle load (N) is not mentioned
in the tractor manual, the minimum rear axle load (N) has to be at least
45% of the unladen tractor mass (A).
In case the minimum rear axle load is not met, you have to add rear
ballast.
To calculate the minimum required rear ballast:
Attention:
In case the front ballast is mounted directly at the tractor, replace “F +
G” in the formula by the “Distance from the centre point of the front
axle to the gravity point of the front ballast”.
Always check the maximum permissible mass, permissible axle load
and permissible tractor tyre load after mounting rear ballast.

Attachment to the
tractor
Since the hitch brackets are reversible, the hitch frame is suitable for
both cat. I and II.
- Cat. I: small diameter pins on the outside.
- Cat. II: large diameter pins on the outside.
Prior to attaching the machine to the tractor, ensure the draft links are
on equal level!
If necessary the PTO drive shaft between the tractor and machine
should be shortened to prevent damage when it is in its shortest
position.
> Check the length of the PTO drive shaft, shorten the drive shaft if
necessary.
Care must be taken to ensure the PTO drive shaft is not shortened too
much, see the instructions that come with the PTO drive shaft.
Always use stabilisers or check chains when attaching the machine to
the tractor, to prevent sideways movement of the hitch frame
damaging the pto drive shaft.
Dependent on the length of the top link, either the front or the rear hole
in the hitch frame can be used.
Transport
Set machine as follows:
> Lift and secure jack stand (1) (if jack had been lowered before).
> Lower machine and start a rh turn. Then pull up and engage lever
(2) under bracket pin (3) from tractor seat using cord (4).
> Ensure both deflectors (5) are positions max. inward and secured;
lift machine to transport position.

Operation
Ope rat ion
General instructions
for use
To enable the machine to follow ground contours correctly, the
hydraulic lift lever should be in float position during work, so that the
lift arms can move freely up and down.
For a good action, the speed of the PTO should be between 400 and
540 rpm depending on the circumstances. This prevents excessive
wear, limits leaf losses and reduced crop pollution.
To limit the working angle of the PTO drive shaft, it is advisable to
make left-hand turns only, especially when raking.
Always make sure that the tines have been fitted correctly.
Adjustments for spreading
and tedding
> Lower machine and start a rh turn.
> Then pull cord (4) to disengage lever (2) from bracket pin (3).
> Set all tines to tedding position (6).
> Use the lower holes (7) for wheel height adjustment: to avoid strips
being left between the rotors (e.g. in a short and difficult crop) it is
advisable to use a higher hole.

Operation
17
> Then lower machine completely and drive a little forward, until the
centre slot at front of hitch frame appears clearly visible (arrow,
fig.).
In this position the forward side of the rotors is nearest the ground.
> Now operate machine at full working speed (350-540 rpm at the
pto) and adjust top link, so that the tine tips are just touching the
stubble in front of the rotors.
Forward inclination of rotors can be set as required for the
circumstances by varying wheel height in conjunction with top link
length!
To prevent the crop being moved too far to the side, especially when
working around the boundary of the field, the tedding width of the
machine can be restricted by the deflectors (5) which can be set
laterally, using stays (8).
Each deflector (5) also can be set into two vertical positions by rotating
the nylon blocks (11) through 180°. Use the upper position under
abrasive conditions.

18
Operation
Adjustment for raking
> Lower machine and start a rh turn.
> Then pull cord (4) to disengage lever (2) from bracket pin (3).
> Set all tines to raking position (9).
> Use the upper holes (10) for wheel adjustment. In long stubbles the
use of the lower holes can be advantageous for better pick-up and
clean raking.
> Lower machine completely and drive a little forward, until the
centre slot at front of hitch frame appears clearly visible (arrow,
fig.).
In this position the forward side of the rotors is nearest the ground.
> Now operate machine at full working speed (350-540 rpm at the
pto) and adjust top link, so that the tine tips are just touching the
stubble in front of the rotors.
Forward inclination of rotors can be set as required for the
circumstances by varying wheel height in conjunction with top link
length!

Operation
19
> Set deflectors as required using stays (8).
Always make certain that the distance between the deflectors is large
enough, especially in a heavy crop to prevent material from being
pulled out of the swath. When you place the deflectors as shown in fig.
the swaths are laid down close together in the first operation. These
swaths are easily put together afterwards.
Each deflector also can be set into two vertical positions. This can be
achieved by rotating the nylon blocks (11) through 180°. Use the upper
position under abrasive conditions.

Maintenance
Maintenan ce
Attention:
Warranty and liability claims of damages caused by inadequate
maintenance (e.g. insufficient lubrication) will be rejected!
General
After a few hours of a new or overhauled machine check that all nuts
and bolts are tight. Special attention should be paid to those holding
the tines and bolts securing the rotors, located under the top of the
rotors. Recheck regularly.
Tines
The HAYBOB 300 has 4 different tines
•'PZ 107E' (5x) = lh, narrow
•'PZ 110E' (5x) = lh,wide
•'PZ 224E' (5x) = rh, narrow
•'PZ 225E' (5x) = rh, wide
Above mentioned tines are Super C quality tines. The cheaper and
lower quality "B"-tines can be obtained by adding an "E" to the part no.
(e.g. PZ107E).
Always ensure that these tines have been fitted correctly, for example:
•The blue marked tines on the left-hand rotor, the yellow marked
tines on the right-hand rotor.
•Narrow and wide alternately fitted.
•Short finger to the top, long finger to the bottom.
•The bend of the tine should be pushed close to the attachment bolt
(see arrow).
