6.1.5 Grinding of cutter knives
Blunt cutter knives causes increased fuel consumption and increased risk of conveyor drum
blocking. Knives might be pressed away from the conveyor drum, causing material to remain
uncut.
Grinding interval length depends highly on the type and contamination of the straw material. If
straw material is mixed with sharp and hard particles, it might be necessary to grind knives
every 250 bales.
Knives should be ground on the
plain
side only. Use a disc for knife grinding, not a regular
cutting disc.
