Cutterbar Spindle Shear Pin
To prevent damage to the cutterbar and drive systems,
each disc is attached to a spindle containing a shear
pin (A). If the disc contacts a large object such as a stone
or stump, the pins will shear and the disc will stop rotating
and move upwards while remaining attached to the spindle
with a snap ring (B).
IMPORTANT:
•
Ensure correct orientation of the shear pins during
replacement.
•
Spindles
