| description | When harvesteing ley there is always mechanical losses from the harvest machines. During
the last years the roundbalers with knives,cutting the material-are more common, This use
increase the mechanical losses of material.
MATERIALS AND METHODS
The roundbaler which used in this test was a Krone Vario Pack 1500 Multi Cut. This
roundbaler has 17 knives. The theoretical length of cut was 64 mm. During the test we
stretched a rubber tarp under the balechamber and collected the materials which fell down
from the balechamber. We collected all of the material from the tarp after every bale and
weighed the loss. The DM was tested in both the bale and the mechanical losses.
RESULTS AND DISCUSSION
The loss of material increased when we used 17 knives. The weight of the loss was 7,3 kg
DM for a one round bale. When we didn´t use the knives the losses decreased to 1,3 kg DM.
If you transform this sum to kg7ha by it was 80,6 kg/ha with the use of knives and 14,6 kg/ha
without, which will be 2,1% and 0,3% of the crop harvested. |

Spill under vallskörd är ett problem som inte har uppmärksammats på samma sätt som tex. spill vid skörd av spannmål och rotfrukter. Under de senaste årtiondet har det blivit vanligt att man använder rundbalspressar för att ta hand om vallfodret och då sker det ofta i form av ensilage, man pressar grönmassan och plastar in balen med sträckfilm. Rundbalspressarna har de senaste åren utrustats med snittaggregat för att bättre kunna packa grönmassan i balen och för att balen skall vara lättare att ta isär. I och med att man börjat använda snittaggregat har spillet ökat under själva pressningen av balen (Andersson.Odat). Men det är inte bara där som det sker spill. Det upp kommer även spill vid slåtter, vändning och strängläggning av vallfodret (Bengtsson.1983).
