4.4 Crop cutting system
4.4.1 General
Feed drum (1) with double tines configured in
a spiral (2) ensures a regular drawing cut of
the blades (3).
The OptiCut cutting system gives the option
to have the crop cut to a theoretical length of
70 or 45 mm at a maximum of 14 or 23
cutting points. The complete blade unit can
be retracted from the conveyor channel using
hydraulic power. The number of blades can
be chosen freely to obtain the desired cutting
length. Engaging and disengaging the blade
unit is possible at any time.
Each blade has its own protective device
against foreign objects. When a foreign
object enters the conveyor passage, the
blade is retracted into the floor of the cutting
unit and then automatically returns to the
cutting position. This function is ensured by
spiral springs on OptiCut 14 and by pre-
loaded hydraulic rams on OptiCut 23.
Note:
When there is a danger of blockage due to
excessive crop density, it is advisable to
swing out the cutting system for a short time
using hydraulic power to allow the crop to
pass through more easily.
When swinging out the cutting system at the
end of the baling process, a final layer of
uncut crop is laid around the bale. That will
minimise the loss of broken crop and
increase bale stability.
Manual engaging/disengaging of knives are done by means of the joystick.
When moving out the cutting system at the end of the baling process, a final layer of uncut crop
is laid around the bales, which can minimise losses of broken crop and increase bale stability.
Operator can select automatic disengaging/re-engaging of knives from the user menu of the
control system. When chamber sensor is indicating bale chamber is full, knife unit will
automatically be disengaged. Continue baling for a few meters to complete bale with a layer of
uncut material, stop baling and continue binding and film wrapping. When discharging bale
knives will automatically return to cutting position.
The hydraulic lock valve on the right-hand side of the machine (at the rear of the pick-up) is to
be closed when the cutting system is used for an extended period in the disengaged position.
