McHale V6750 - Netting System; Bale Density Gauge

McHale V Series Baler

Knife pressure too high warning
A warning will always be shown when the knife pressure is above working pressure.
Lower the knives, then raise again to reset to the normal working pressure.
9.9 Netting system
In an automatic cycle the control box emits a single beep when the bale reaches 90%
(adjustable) of the set diameter. Further to this when the bale diameter reaches 95%
of the diameter the moving roller under the netter unit is triggered and the roller moves
to it’s inward or netting position. The box will then emit a series of beeps when the bale
has reached it’s predetermined diameter, this alerts the operator that netting is about
to start. Note: The operator must stop the forward movement of the tractor at once!
Next a continuous beep informs the operator that the netting has started. After the
preset number of net layers are applied to the bale, the net is cut. The tailgate can then
be opened to eject the bale from the bale chamber, this will also reset the netter knife
and the moving roller. Once the bale is ejected the tailgate can then be closed and once
the tailgate is fully closed a single beep will inform the operator that the door locks are
engaged and baling can resume.
9.10 Bale density gauge
The bale density gauge is used to indicate the pressure
applied to the belt tension rams (on the small side). When
the tailgate is closed, and no material in the baling chamber,
the pressure shown on the gauge is known as ‘starting
pressure’. This pressure will then increase due to the oil in
the cylinders being forced through the density valve as
material begins to fill up the baling chamber. The density
pressure is irrelevant for approximately the first 600 mm of
bale formation, as the density is regulated by the tension
springs. The density will then rise to the core density setting
and after that the needle should rise to the set bale density
and remain there until the bale is complete. Pressure should
never go above 210 bar, if it does consult your McHale
dealer. Crop type and bale density will also affect the net tension on the finished bale.
WARNING: Do not bale if the knife pressure is too high!
Do not bale if the knife pressure is too high as machine damage will
occur!
