We have prepared some recommendations on what to look for in case of problems with the shape of the bales. Shape, line condition and driving technique always play a role.
Large parcels of land are now usually harvested with several threshers with different working widths or threshing gears. Consequently, the rows will also be baled differently. Currently, the worst pressing rows are after axial combines in the case of working widths over 11m.
The operator's driving with the baler machine in line has an effect on the final shape of the bale:
- Bad guidance function of the baler machine → check service settings (displayed on the terminal).
- Operator does not respect the shape of the lines → according to the guidance (non-functional or damaged display).
- Ideal row shape - ideal raking of small rows into one large row by means of a centre stacker, which ideally forms an even row.
- Wrong bale shape - twists into a roll shape - twine will crack from the side gradually cracking all of them.
- Bale coming off the ramp during the pressing run at the moment of a sharp turn. Subsequently, due to the heavy sideways impact, the twine will crack.
Twine breaks exceptionally on one bale!
- Hasn't the bale already been pressed once?
Bale collapsed.
- Problem high weight density of the bale, as the mass is over-pressurised, it is compressed even more and the twine cannot support this weight. After a while, tension occurs and all the twine cracks at once behind the knot. The reason for this is that, although it doesn't seem like it, the overmolded material, once it has been compressed, subsequently expands more and does not hold the strength of the twine.
Examples of an improperly filled bale due to poor bunching technology or failure of the operator to respect the shape of the line.
Example of a bale being deposited when the baler is turning sharply on the headland. Subsequently, the impact may cause a part of the twine to break and the bale to disintegrate.
