10.6 Chopping system
The McHale Fusion 3 is equipped with a 23 knife chopping system for fine cutting. If
a coarser chop is required 11 of the knives can be removed, or all of the knives can be
removed, if desired, see “Chopper unit knife removal & installation” on page 43. The
knife buttons on the control box will move the knives into the feeding channel or retract
them. It is recommended to switch the chopping device off when baling very dry
material.
In order to protect the chopping device against overload and damage, hydraulic
accumulators are connected to the actuation circuit.
10.7 Selectable knives
Selectable knives are available as an option on the McHale Fusion 3 Baler & Wrapper.
The operator can select between 0, 11, 12 or 23 knives from the control box. The knives
must be fully down, before selecting the desired set of knives. See Section “Knives
Operation” on page 62.
NOTE: Keep the knife slots clear of material
To keep the knife slots clear of material, it is recommended to switch the
knives on and off several times daily. To do this, press “knife selection”
once (Softkey A), while the control box is in automatic mode. This will
move the knives to the opposite position. One more press will move the
knives back to the original position. See “Knives Operation” on page 62
for proper control unit operation of the knives.
