The baler packages the hay or straw into bales.
Bales are either round or rectangular.
The baler in the photograph produces round bales.
Baling is done because it is easier to handle the hay and straw.
Large bales are moved by forklifts.
The round baler produces cylindrical bales of 1.2m wide by 1.2/1.5m diameter.
The round bales can weigh 200kg for straw and up to 350kg for hay.
Making The Bale
The baler machine accumulates material as the tractor drives across the field.
When the bale chamber is full the farmer stops driving forward.
The machine then wraps six or more turns of string around the bale.
The string is then cut but not knotted.
(Some balers wrap two turns of plastic netting round the bales.)
The bale is then discharged through the rear gate of the baler.
The bale rolls down the ramp and away from the baler.
The rear gate is then closed and the tractor can be moved forward again for the process to be repeated.
