Kuhn Rundballenpresse / Round baler

A round baler such as the VB3195 picks up swathed forage using a tine pick-up and feeds it into a bale chamber, where rollers, belts or chains shape it into a round bale. On a variable chamber, the bale grows from the inside outward up to the set size, while a fixed chamber always produces the same diameter. A cutting rotor ahead of the chamber shortens the stalks and thereby increases bale density; at the end of the cycle, the machine ties the bale with net or twine.

Size depends on the tractor power needed for the pick-up, bale chamber and, where fitted, the cutting rotor. On the road, the trailed implement is subject to the general rules on width, lighting and marking.

On a used machine, what counts is the condition of the belts or rollers in the bale chamber for wear and cracking, the tension and wear of the chains, the sharpness and completeness of the cutting rotor's knives, and the condition of the pick-up tines. The net or twine binding unit and the bale-chamber bearings should also be checked. It is also worth checking the tailgate's hydraulic hoses and the chassis tyres, which on a round baler are exposed to unusually high loads.
