Wet Bale Marker - Wet Bale Management

The Bale Marker is the easy and cost effective method to mark the bales that have high moisture spots. The Wet Bale Marker can be linked directly into Moisture Pro System or the fully Automatic Applicator. The Wet Bale Marker will spray a red food grade colour onto the bale flakes that have moisture readings above the alarm point. Marking high moisture bales allows the operator to store only bales within their preferred moisture range into the stack.  All the marked bales can be stored separately as the quality of these high moisture bales will be reduced and so they will dry out and not damage surrounding bales that are within the operators preferred range.
