Abstract: A lopper or lopper head attachment may include a primary gear, a secondary gear, a ratchet gear, an engagement flag, a dampened lag bolt, and a cutting blade. The secondary gear may be enmeshed with the primary gear. The secondary gear may define a lag groove radially offset form the secondary axis. The ratchet gear may be rotatable about a secondary axis separately from the secondary gear. The engagement flag may be rotatably mounted to secondary gear to move between an unengaged position and a engaged position. The dampened lag bolt may be slidably received within the lag groove to move relative to the secondary gear between a permissive position and a restrictive position. The cutting blade may be in mechanical communication with the ratchet gear to be pivoted thereby, in the engaged position of the engagement flag, to a closed position from an open position.
