ExactFeeder II bale chopper and reservoir

Automated round bale chopper with integrated feed table

The ExactFeeder II bale chopper and reservoir is the second generation of our automated bale chopper, developed on experiences and principles from the well-known FlexiFeeder. The improvements for the ExactFeeder II include sophisticated PLC, internet connection, load cells and a new knife drum capable of holding 60 knives.

Product Overview

ExactFeeder II bale chopper and reservoir is developed to be a part of automated feeding systems, delivering steady flow, high capacity and well cutting of forage.

The machine may be used as a stand-alone chopper and reservoir, or in a semi or fully automated system. Used with a TMR-mixer or feeding wagon, the ExactFeeder II will contribute to a more flexible and effective utilization of the feeding system.

Reinforced drums

ExactFeeder II is delivered with reinforced knife and spiked drum, to withstand the wear an automated system is exposed to.

It is equipped with 20 knives as standard to ensure good cutting and high capacity. The knife drum is capable of holding up to 60 knives and is rotating at 380 rpm.

By changing the type or number of knives, the ExactFeeder II can be customized to suit your forage mass.

Are your knives good enough?

The knives are regarded as the heart of the machine.

Over time, the knives will become dull. This is observed by longer cutting time and poorer cutting, and is fixed by sharpening the knives. After repeated sharpening, the knife may be worn out. Check height and shape by comparing the knife with our knife wear template.

Straw or frozen mass?

Making the forage rotate in the chopper is fundamental for optimal function. Straw or frozen grass may in some cases rotate poorly in older machines.

The remedy in these cases may be to to weld knobs to the carriers on the conveyor.
