If bales are hard and well formed they can be stacked vertically but loose and misshapen bales with low solid content should not be stacked higher than one layer as this could easily cause deformity and the danger of runoff will be increased Bales can also be stored on their sides The layer of plastic is thicker here providing greater protection against piercing Bales should be covered with a tarpaulin or a fine mesh net to protect against birds and small rodents If the plastic is pierced it must be sealed with weatherproof hard wearing tape preferably under the outermost layer of plastic Ensure that the hole is adequately sealed The best wrapping results are obtained by harvesting the grass early drying it out to 30 40 solid content If there is a danger of rain bale and wrap the grass anyway taking care not to mix any earth in with the grass Using a baler which produces even firm bales wrapping the bales soon after baling never later than two hours afterwards using a good type of plastic and six layers of plastic This removes the need to use preservatives storing bales in the shade to reduce the danger of air leakage 4 0 4 1 4 2 4 3 4 4 NB 4 5 4 6 SETTING UP MOUNTING OF THE MACHINE Due to transport the prestretcher may not be mounted when delivered THE PRESTRETCHER is to be mounted on the right side of the machine It is adjustable different heights afte
