Baling with large rectangular balers continues to increase year on year, with this increase in popularity has come a demand from contractors and large scale farmers to be able to produce ever more dense and compact bales, to maximise the output of the baler.

To satisfy the close tolerances on bale density, weight and bale shape required by the customer creates a need for a strong baler twine, capable of delivering the extremely high performance necessary from such demanding baling conditions.

Hi-Yield Big Bale Twine is able to offer the high knot strength needed when baling either the heaviest silage bale or the most dense barley straw bales, without letting you or the baler down. Produced under a Quality Assurance System, the exceptional quality and strength of Hi-Yield Big Bale twine is derived from a combination of top grade raw materials and manufacturing expertise; taking the highest quality resins and extruding the raw material under closely controlled manufacturing tolerances, to produce the finest yarns from which to produce top class baler twine.

Each pack of Hi-Yield Big Bale twine contains 2 individually shrink wrapped spools, with unique i/d marking to ensure full traceability throughout the life of the spool.

Large rectangular straw baling

Very careful attention should be paid to the bale pressure depending upon the type and condition of crop being baled. For instance, during periods of extended dry and hot weather, the baler may produce bales with lower density and of significantly less weight than in more humid conditions, with the same baler pressure settings. Increasing the bale density setting, in an effort to produce heavier weight bales, will exert greater tension on the twine and could lead to potential twine failures. In such circumstances it may be advisable to suspend baling until later in the day, when temperatures have dropped and humidity levels increased slightly.

Large rectangular silage baling

For baling good quality large rectangular silage bales, it is important to follow a few simple guidelines:

Ensure the crop has wilted to a minimum of 40 - 50% dry matter (DM), which will produce well formed bales as well as allowing excellent fermentation.

Ensure the twine tension is reduced as much as possible, as twine friction experienced between silage bales during baling is much greater than when baling
        straw.

Eliminate as much air as possible from the crop when baling, as it is essential that sufficient crop is packed into the top of the bale to avoid misshapen bales being
        formed, which may be difficult for an automatic bale-wrapper to handle properly.
        A reduction in forward speed will help to achieve this by increasing the number of
        wads per bale.

Bales per pack information table

Note: the above figures are only a guide and may
       vary depending upon conditions. These figures
       represent the approximate number of bales
       possible from each 2-spool pack, although more
       spoolswill obviously be required satisfy the
       number of knotters. This information should be
       used as a guide to calculate the amount of twine
        needed when baling.

Wrapping square bales

Wrapping square bales poses much more of a challenge than round bales, as the bale cross- section is continually changing relative to the plane of the film web coming from the film roll.

The ever changing bale surface shape the film is being applied to, as the bale turns, creates varying degrees of tension to the film web. When wrapping over corners, this can create uneven film stretch against the bale, meaning areas of thinner, over-stretched film at the point of greatest stress that can easily lead to tearing and film breaks.

Owing to the differing height of some bales, compared to their width, the bale may not turn uniformly on the wrapper, causing extreme variation in the film coverage of the bale and exerting extreme tension on the film at certain times of the wrapping cycle. As a consequence, it is recommended that the bale be wrapped as if applying 2 more film layers than required.

All silage square bales should be wrapped with a minimum of 6 film layers to cater for this, ensuring that everywhere on the bale has AT LEAST 4 film layers. When wrapping higher Dry Matter forage, the bale should be wrapped with a minimum of 8 layers to ensure AT LEAST 6 film layers everywhere.

Hi Yield Twine is now approved by:

The Hi-Yield brand of baler twine is very well known and respected throughout the United Kingdom as a high quality, high performance product, suitable for all baling requirements, large or small, in any and all crops.

  This fact is fully recognized by The SIMA Group, a company with more than 100 years’ experience in the manufacture and supply of machinery for baler twine production and the acknowledged world leader in this field.  All Hi-Yield brand baler twines are produced on machines manufactured by The SIMA Group.

All products bearing the  logo carry the assurance that these twines have been manufactured to The Sima Group’s specification and under the company’s strict quality control programme, guaranteeing not only the product performance but also the specification to which it was produced.  

In the very competitive and, often, confusing marketplace, where many spurious brands and makes of twine are offered, it is important to recognize and understand the quality and security that comes with a well known brand, and appreciate that SIMA Group approved baler twines guarantee the consistency and performance required, together with the assurance of security and support in the field.
