Rear Attachment Settings
Spike Drag Settings
1.
On the spike drag, start with 5 links hanging from the
chain in drag arm bottom slot. (This is the starting
point for worst conditions). The cleaner the ground,
the shorter the pull chain may be pulled up. On the
spike drag, one of the links in the first row of angles
is turned over. This allows the trash to start flowing
through the drag easier by changing the angle of the
first row of teeth. Always make sure that the drag is
never pulling off of the hang chains. If so, shorten
pull chains
