445 - Simply solid

The proven header for harvesting thin-stemmed crops. The simple, practical design of the rotary intake system, consisting of four intake and two transport drums, ensure that service and maintenance work is kept to a minimum.

Wide range of applications

Wide range of applications: Maize, sorghum, sunflowers, whole crop silage, oilseed rape, hemp, pampas grass, etc. Two mechanically driven crop dividers for heavily laid crops, height adjustable crop lifters.


The outer cutting rotors are folded hydraulically to give a transport width of 2.47 m. The transport guard is fitted with flashing lights and position lights. When folded, the cutting units may partially cover the headlamps on some self-propelled forage harvesters. It may be necessary to re-position the headlamps to conform with the prevailing highway regulations. Counterweights must be fitted in compliance with applicable government inspection survey regulations.


Row independent cutting system

Row independent cutting system with high speed cutting rotors and freewheel mechanism. Cuts across the entire cutting width by means of enclosed saw type rotor blades with replaceable segments. Fast rotating cutting rotors also cut under heavy circumstances, for example, weeds or whole crop silage. 


Tungsten carbide coated saw type blades, manufactured with quality certification, self sharpening, lower load placed on clutches and transmissions. Available as service set.


The 400pro series features special shaped cleaners. The sharp edged maize stubble is broken up by the cleaners placed under the cutting rotors. This not only protects the tyres of the forage harvester, but also speeds up the decomposition of the stubble.

Drum Pointers

The Pro series from Kemper now have a new patented tooth shape with a ‘claw’ that securely grips and holds the plants and guides them straight into the feed channel. This new drum design latches every single plant even on headlands.

The bonus in equipment

Stress-free operation – thanks to the automatic row guidance with the new KEMPER Sensor.

The new sensor in the central crop divider assists steering.

A magnet is embedded in the plastic. The black sensor measures the distance and obtains a steering signal.

Advantages of the new KEMPER Sensor

- Increased working speed thanks to automatic row guidance

- Lower stress on the driver, bringing improved performance

- Full driver-concentration on what is important

- The harvester does not lose its track even when a row is missing

- Innovative software compensates for missing signals

- Low-wear, zero-servicing design of the steering system


2-speed transmission

A 2-speed transmission for optimised intake speed - especially with larger chopping lengths.

Liquid cooled friction clutch

Liquid cooled friction clutch: The KEMPER solution for optimal power transmission prevents overheating, provides longer service life than standard type clutches - available as a field installed kit.

Increased durability and minimal wear

Professional customers prefer Kemper harvesting headers because of their high versality and operational reliability. They achieve a higher annual throughput and are expecting a longer service life and a minimum maintenance during the season. Kemper has taken this into account and offers longlasting, heavy-duty components for all critical wear parts of the Pro series. This applies to parts like saw blades, skid shoes, pointers and various feeding drums.
