Cutterbar; Replacing Knife Section - MacDon D65 Operator's Manual

5.5 Cutterbar

The cutterbar is located on the front of the header. It supports the knife and guards which are used to cut the crop.
WARNING
Keep hands clear of the area between guards and knife at
all times.
CAUTION
To avoid personal injury, before servicing machine or opening
drive covers, refer to 5.1 Preparing Machine for Servicing, page
119.
CAUTION
Wear heavy gloves when working around or handling knives.

5.5.1 Replacing Knife Section

Inspect the knife sections daily and ensure they are firmly bolted to the knife back and are not worn or damaged (worn or
damaged sections leave behind uncut plants). Worn or damaged sections can be replaced without removing the knife from
the cutterbar.
NOTE:
Coarse serrated knife sections last longer than fine serrated sections in dirty or sandy conditions. Fine serrated knife
sections perform better in fine-stemmed grasses and plants that contain more fibrous stems.
1. Shut down the windrower, and remove the key from the ignition.
2. Stroke the knife as required to center knife section (A)
between the guards.
3. Remove nuts (B).
4. Remove the bars and lift the knife section off the knife bar.
5. Remove splice bar (C) if the knife section is under the bar.
6. Clean any dirt off the knife back and position the new knife
section onto the knife bar.
IMPORTANT:
Do NOT mix fine and coarse sections on the same knife.
