INTELLIGUARD™ METAL DETECTOR PROTECTS CUTTERHEAD AND LIVESTOCK
The available IntelliGuard metal detector protects the cutterhead and livestock from ingestion of iron-based metal objects.

When stray metal is detected, a sensor in the lower feedroll sends a signal to a solenoid, which causes a pair of locking pawls to stop the feedrolls.

The sensor then alerts the operator to the metal location in the feedrolls by LED lights on the monitor.

A red light and alarm on the control (shown) alert the operator when metal has been detected.

Diagnostics and calibrations
The self-diagnostic system allows the operator to test the metal detector to ensure it is operating correctly.

IntelliGuard can be calibrated and adjusted for maximum sensitivity under various crop, field, and machine conditions.

If feedroll damage occurs, IntelliGuard can be recalibrated to account for the damage and still maintain the ability to sense ferrous metal.

EXCLUSIVE DURA-DRUM™ CUTTERHEAD ENCLOSED-DRUM DESIGN SAVES FUEL, POWER, AND MONEY
The cutterhead is equipped with 48 individual knives on the 3975 Pull-Type Forage Harvester (PTFH) and 36 individual knives on the 3955 PTFH.

The segmented-knife design allows material to move away from the cutterhead more efficiently. The produces a high-quality cut (even through heavy mats) while using less horsepower.

The slotted mounting holes allow the knife to retract if rocks or other obstructions are encountered.

To replace the damaged knife, simply loosen the mounting bolts.:
- No need to replace additional knives to balance the drum
- Saves time and minimizes repair costs
