Bale & Film Requirements
6.1 Bale requirements
The bales to be wrapped should be well shaped, dense and of suitable quality for
making silage. Substandard material will not produce good quality silage regardless of
how well the bale is wrapped.
6.2 Film requirements
Good quality silage depends on the use of top quality plastic film, in addition to well
shaped, dense bales. Low quality film material will not produce good silage regardless
of how well the machine wraps the bale. The film should be used and stored according
to the instructions of the film manufacturer.
It is recommended that a minimum of four (4) layers of film are applied to the bale. If
the material being wrapped is of a hard or stemmy nature it may be necessary to apply
six (6) or eight (8) layers to ensure a good, airtight package.
Only 750 mm film is to be used, unless otherwise stated.
The operator needs to ensure that the bale is correctly wrapped. It is good practice to
periodically check the bales after being wrapped for any torn, split or punctured plastic
film. If the stubble in a particular field has a tendency to puncture the plastic film, it is
strongly advised to wrap the bales at the stack, where there may be more control over
ground conditions.
The plastic film must be applied to the centre of the bale. If it is too low or too high adjust
the dispenser height as appropriate. See “Dispenser height” on page 62.
To determine the number of wrapping arm rotations required to cover a
bale carry out the following procedure:
1. Using manual operation, from the control box, manually count the number of
wrapping arm rotations* to cover the bale completely with plastic film.
2. Add 0.5 to this number.
Bale width: Between 1200 mm and 1270 mm wide
Bale height: Diameter from 1200 mm up to 1350 mm
