Abstract: An apparatus for controlling animal pests has a housing having a passage extending into the housing, the passage having a front wall and a rear wall, an impacting member movable across the passage from the front wall to the rear wall, the impacting member having a slidable arm extending out from the rear wall and having a free distal end having an impactor extending downwardly from the free distal end of the arm at the front wall, a retraction mechanism having a first support and a second support with the first support being integral with the rear wall, and a spring connected to the second support and the arm, a sensor positioned within the passage for providing a signal representative of the sensing of the presence of the animal pest, and the impacting member is operable to be released to rapidly move across the passage.

Abstract: An apparatus for controlling animal pests comprises a housing having a passage extending into the housing from an entrance, an impacting member movable across the passage and a planar sensor spaced apart from the kill bar by a predetermined distance along the passage towards the entrance, the planar sensor configured to sense the presence of the animal pest across a sensing plane across the passage wherein the impacting member is operable to be released to rapidly move across the passage when the planar sensor indicates the presence of the animal pest as passed through the sensing plane.

Abstract: A method and apparatus for controlling animal pests wherein the apparatus comprises a housing having a passage extending into the housing from an entrance, an impacting member movable across the passage, at least one scanner positioned to scan the animal pest a processor. The processor is operably coupled to the at least one scanner and the impacting member and is configured to receive information from the scanner and adjust at least one operating parameter of the impacting member wherein the impacting member is operable to be released to rapidly move across the passage. The method comprises scanning with the scanner the animal pest and adjusting with the processor, at least one operating parameter of the impacting member.

Abstract: A replaceable cutter tooth for mounting to a saw blade has a concave front cutting surface extending from and between opposite kerf forming linear side edges, and from and between a radially inner curved edge, radially inner when mounted on a saw blade, and a radially outermost curved cutting edge.

Abstract: A replaceable cutter tooth for mounting to a saw blade has a concave front cutting surface extending from and between opposite kerf forming linear side edges, and from and between a radially inner curved edge, radially inner when mounted on a saw blade, and a radially outermost curved cutting edge. A groove extends in the radial direction from the radially inner curved edge to the radially outermost curved edge, generally medially between and substantially parallel to the side edges so as to reduce the surface area of a front face of the front cutting surface of the tooth for ease of re-sharpening in the field.
