DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll baler which collects collected grass, such as cut grass, threshed straw, and leaves it on the ground, compresses it into a roll-shaped bale, and packs it. The size can be changed.

[0002]

2. Description of the Related Art In a roll baler, a roll-shaped bale is compressed and packed by a roll baler pulled by a tractor, and the bale packed by the roll baler is lifted and moved by a lift device attached to the front of the tractor. There are large roll balers and small roll balers, which are self-propelled roll balers and can be used to manually load compressed and packed bales into a truck. In these large and small roll balers, the size of the bale to be compressed and packed is substantially constant.

[0003]

The size of a small roll baler is considered so that the bale packed in a compressed package can be manually loaded on a truck or the like, but the grass to be collected is raw. If it is wet or wet, the bale packed in the package will be heavy and it will be difficult to handle it manually. Therefore, an object of the present invention is to make it possible to easily change the diameter of a bale to be compression-molded in order to facilitate handling of a packed bale according to the state of a collection.
