5. MACHINE CHARACTERISTICS
5.1. General characteristics
The machine is destined for a standard, typical agricultural application, i.e. for wrapping bales
of straws and other plants intended for ensilage, wrapped up into round bales with use of baling
presses. The bale diameter must be in range from 1,2m up to 1,5m in respect its weight must not
exceed 1200kg . Foil 750mm wide is used for wrapping to provide optimum efficiency. Bales are
meant for ensilaging after wrapping.
The wrapping machine should be used in accordance with its purpose. The wrapping machine
is adapted for combined with tractors of power greater than 30 kW and class min. 0,9 equipped
with a pump allowing for oil flow on the level of 20-45 l/min and the pressure value of
150 - 200bar .
Straws and other papilionaceous plants intended for ensilaging and wrapping should be
mowed at the beginning earing phase (most preferably in the afternoon). After couple of pre-drying
hours (next day after mowing) mowed material should be collected with use of wrapping presses
considering favorable weather conditions. Bale pressing extent should be at the maximum.
In practice, directly after bailing with press (within 2 hours at maximum) the bales should be
wrapped by the wrapping machine. Bales left for longer time experience unfavorable digestion
process. After wrapping, the bales should be set (taking special care in order to not perform the
foil) for 6-8 weeks on flat and dry surface. The wrapped bales fermentation process should be car-
ried out at positive temperature values.
The bales wrapped may be stored in two layers. After two months, the hay/ensilage is ready
for feeding as a full value pasture.
