6. Lockrod
• Dual function:
a. Acts as a wedge when advanced between locking balls,
causing them to move outward in the ball canister and pushing
the locking balls into the ball tracks of the cutting unit (not shown).
b. Acts as a wedge when retracted using a raised, tapered key to
force the bump-off pin against the cutting unit (not shown).

• Precision, chrome alloy-steel hardened balls used to transmit
pull-back force to the cutting unit.
8. Bump-Off Pin
