3 General description
3.1 How the round baler functions
The functions of the roll-baler are controlled via the control box (installed in the tractor cab), machine
box (on the right-hand side of the machine), and a single- and double-acting controller.
The functions lift/lower pick-up and swivel cutting knives in/out (only featured on 125 OC) are preselected
by way of a hydraulic multi-way valve plus pull rope in the tractor cab. The tying options are selected
with the control and machine box. The roll-baler compresses the swathed green feed, hay and straw
into round bales. A pick-up reel lifts the swathed crop and feeds by way of a baffle plate pressure
(optional) to the conveying channel. The conveying augers mounted on the outside of the conveying
drum narrow down broad swaths to the width of the compressing chamber. The conveying drum is
fitted with double tines in a spiral arrangement (transport tines on 121 R / 125 R) to ensure that the
compressing chamber is continuously and uniformly filled.
When equipped with the high-performance „OptiCut 14“ cutting assembly and swivelled-in cutting
knives, the crop is passed over up to 14 knives and cut. Each knife is individual protected by a foreign-
object guard which automatically moves the knife back into the cutting position when encountering a
foreign object. The roll chamber compresses the crop into firm and stable bales.
The compressing pressure can be selected according to the prevailing harvest conditions and the
requirements expected of bale density. Tying can be started automatically or manually. Twine or netting
can be used for tying, depending upon the given configuration. The rear gate is opened by the driver
when tying has been completed, and the bale rolls out of the compressing chamber.
The bale can be gently deposited outside the rear gate area by an optionally available bale roller
chute.
The rear gate is then closed again and a new baling operation can commence.
