The project du jour is to refurbish the cutting parts on the draper headers. John has brought in replacement “sections” for the knife in each header– the JD 640FD and the MacDon FD75. Each is 40 feet wide. The JD requires 120 and the MacDon uses 160 of the little triangular sections. When this is complete, the cutting parts of each header will be like-new.
The MacDon draper header is out today. The knife has been pulled out to be rebuilt in the shop.
These little triangles are called ‘sections’, and these are what we’re replacing today.
Brandon and John bolt the sections to the MacDon knife in the shop. When done, it will be slid back into place in the header. We also store a spare knife in a special holder in each header.
Here is the John Deere version of a ‘section’. Each one fastens to the knife with 4 little bolts
Here, Brandon removes the old sections, and installs the new.

Winter projects like this are a good preventive maintenance idea. It makes for a more productive field time next harvest time!
