5.3.9 Disc Spindles
To avoid damaging the cutterbar and its drive systems, each disc is attached to a spindle which incorporates a key
that shears if the disc contacts a large stone, a stump, or other large object. In the event of a sheared key, the disc
stops rotating, but remains attached to the spindle.
