What is a Baler Used For and How to Transport

A round baler produces cylindrical, rolled bales that result in a ‘thatched roof’ effect that can withstand pressure from the elements. Cut plants are rolled up inside the baler using fixed rollers, rubberized belts, or a combination of the two, until they reach a predetermined size.

Round balers can have variable chambers that typically produce bales between 48-72 inches in diameter and up to 60 inches in width. Depending on the size, moisture content, and crop, these bales can weigh between 500 and 1,000 kg. Some farmers may also use roto-balers or mini round balers to produce round bales between 20-22 inches in diameter and 20-28 inches in width. These smaller bales usually weigh between 18-25 kg.

Once they reach the desired size, twine or netting is wrapped around the bale to help it hold its rounded shape. Then, the back of the baler swings open, and the full bale is discharged onto the ground. Though considered complete at this point in the baling process, some farmers choose to protect bales by wrapping them in plastic sheeting using a bale wrapper, especially if the bale will be stored outside. A bale wrapper can also help to convert a round bale of damp grass into silage.

When it comes to transport, rectangular bales are often considered easier to transport. There is little to no risk of rectangular bales rolling off a flatbed trailer for transport, and the rectangular shape means they can be stacked in solid slabs, both for transport and storage. Most rectangular balers have the option to produce bales that are twice as wide as they are long, meaning they can be stack in alternating overlapping groups in a robust brick-like structure.
