40 Messer-Trommel

The K103888 is a 40-knife cutter drum designed to fit John Deere® 6000 series and 7200-7580 series self-propelled forage harvesters (SPFH). This drum works with cutter knives to efficiently cut harvested material.

Key Features:

This cutter drum features angled knife brackets, allowing you to use either K63136 corn knives or K69500 grass knives for versatile cutting options. It includes a Kooima Ag exclusive removable center shaft, making maintenance and replacement easier. Built for durability, it has a thicker wrap, reinforced sidewalls, and a center support plate to enhance rigidity and extend wear life.

Control Your Length of Cut – The number of knives on the drum affects the cut length:

• 40-Knife Drum (this model) – Produces a longer cut length.
• 48-Knife Drum – Provides a balanced, mid-range cut length.
• 56-Knife Drum – Produces a shorter cut length.

Installation & Replacement:

• Install according to factory settings.
• Requires K71387 hub and K19M8610 bolt (sold separately).
• Inspect regularly for wear; hairline cracks between knife brackets indicate it's time for a replacement.
• Replace the drum when knife brackets are wearing thin or if the bearing spins on the shaft.
