Knife pressure too high
This tells the operator that the hydraulic pressure holding up
the chopping knives is too high for baling which could lead
to knife or machine damage. This warning will be seen if
manually raising the knives with max. pressure. (See ‘Knife
operation’)
Knives are too low
This will be displayed if the knives lower even slightly while
baling to warn the operator of less than optimum crop
chopping.
The knives may be blunt or a hydraulic problem may be
causing the knife pressure to drop too low allowing the
knives to retract.
This warning is shown on selectable knife machines when
the second set of knives lower even slightly while baling to
warn the operator of less than optimum crop chopping.
