10.8 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. For the first
500 mm of the bale the density will 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 200 bar, if it does consult
your
McHale
dealer.
10.9 Setting the bale density
The bale density gauge is divided up into increments of 20 bar per increment and has
a yellow zone, green zone and a red zone, as a quick reference during machine
operation. When baling drier materials such as straw or hay
McHale
recommend
setting the bale density pressure between 70 and 110 bar pressure (setting 4 - 5).
When baling wetter materials, such as grass for silage, a pressure of between 110 and
160 bar pressure is recommended (setting 7 - 8). The bale density can be controlled
from the control box. The density can be set from 1 - 10. Normally a maximum of
160 bar is adequate to produce good dense bales. A higher setting may be required in
wet crop conditions. The selected density setting is displayed on the main screen.
CAUTION: Bale density pressure should not go above 200 bar
The bale density pressure should never be adjusted above 200 bar
pressure. If 200 bar is exceeded, damage to the machine components
may result.
