Krone Big Pack 127 / MultiCut, Operating Manual, Page: 21 / 132

II - 11
Safety
The conveyor feed rakes (4) fill the conveyor channel.
The crop is pre-compressed by the action of the rakes.
Der Fülldruck im Förderkanal wird von Tastreche (16)
abgetastet. Bei Erreichen eines bestimmten Druckes
wird der Tastrechen zurückgeschwenkt und a feeder
rake transports the crop further into the bale channel.
The baling ram thrust is controlled automatically by the
hydraulic cylinder (9) at the bale channel flaps. When the
set pack length has been reached, the knotter me-
chanism star wheel projecting into the bale channel is
actuated. The
Big Pack 88 is equipped with 4 knotters
(7) and the Big Pack 127 and 128 with 6 knotters (7).
The packs are deposited by a two-part pack chute (10).
In the bale channel the pre-compressed crop is pressed
to a highly compressed big pack by the baling ram (6).
The length and of course the density of the pack are
infinitely variable.
Big packs can therefore be produced for the most varied
of requirements.
Special Equipment
Swath distributor:
A swath distributor is available as an extra to ensure an
even feed of the bale channel with narrow swathers.
Hydraulic folding bale chute with rollers:
Especially when using the big baler for baling grass
silage, the rollers in the bale chute make it easier to
deposit the bales.
Compressor:
If hydraulic brakes are used on the big baler, a
compressor can be installed as an extra for knotting
device cleaning.
MultiCut:
The MultiCut cutting system is available particularly for
silage recovery or when short bailing material is needed.
A size reduction to as little as 45 mm is possible using
this.
Wide pick-up:
To better deal with wide harvester-thresher swaths, the
big baler can optionally be delivered with a wide pick-up
(2.4 m).
Anhängung Exportvarianten:
Je nach landesspezifischen Anforderungen stehen eine
drehbare Zugöse oder eine Hitch-Anhängung zur Verfü-
gung.
Double knotter
Bei der Bergung von Silage hat der Doppelknoter gegen-
über dem Einfachknoter einige Vorteile. Das Garn liegt
während des Pressens nicht im Knoter. Dadurch bleiben
sowohl Knoter als auch Garn während des Pressens
verschleißfrei. Die Bindeeinrichtung mit Doppelknoter ist
allerdings aufwendiger im Aufbau und in der Wartung/
Einstellung.
The BIG PACK Baler must be driven by a tractor with at
least a 65 kW (85 bhp) power output.
The BIG PACK Baler is hitched to the trailer coupling or
the swinging drawbar.
The swinging drawbar is fitted with a height adjustment
feature so that the big pack baler can operate in a
horizontal position.
The drive to the BIG PACK is via a PTO shaft which
transmits the torque from the tractor via a flywheel mass
(11) to a straight bevel gear pair (12). The maximum
input speed of 1000 rpm may
not be exceeded, as there
is a risk of the machine being damaged.
The PTO shaft is equipped with a wide angle joint on the
tractor side. The operating instructions for the PTO shaft
are located at the PTO shaft. Before putting the big pack
baler into operation, the operating instructions for the
PTO shaft should also be read. These detail in particular
the shortening of the PTO shaft as well as any repair
and maintenance work.
The 2 m (2,4 m) wide pick up (2) collects the crop
cleanly.
A height-adjustable baffle plate (1) ensures error-free
collection and helps prevent blockages. The baling
material is carried via 2 filling augers (3), which are on
the left and right side of the pick-up, to the rake drum
(13) or the cutting rotor (14) and blades (15).
The pick up can be raised and lowered with the tractor
hydraulics. The feeler wheels on the pick up are height-
adjustable so that the optimum pick up collection height
is always reached.
