A saw bench having a first pair of legs and a second pair of legs. Between the first pair of legs and the second pair of legs are two cross members for material to be cut. A sawing kerf is formed between cross members. A first guide rail and/or a second guide rail for a sawing member is mounted on the saw bench in such a way that, during sawing of the material to be cut, the sawing member engages through the sawing kerf below a level of the material to be cut, which is held by the two cross members.

A machining tool, in particular to a rotating cutter machining tool, includes at least one cutting strand and at least one cutting strand-guiding unit. The machining tool also includes at least one cutting edge-guiding unit disposed on the cutting strand-guiding unit. The cutting edge-guiding unit has a maximum transverse extension that is equal to or greater than a maximum cutting width of the cutting strand.

Disclosed is a chainsaw capable of introducing outside air into a body casing by rotation of a cooling fan to adequately cool a control unit provided inside the body casing. The chainsaw is configured to cool a control unit provided inside a body casing by a cooling fan being rotated under driving of an electric motor, wherein a handle comprises a base portion through which the handle (30) is attached to the body casing, and a grip formed to extend from the base portion in such a manner as to be grippable by a worker; and an air inlet is formed in a counter wall of the body casing opposed to the base portion of the handle, and wherein the base portion is attached to the counter wall of the body casing to cover the air inlet in an air introduceable state.

A handheld driving apparatus is provided for mowing or cutting an object. The driving apparatus comprises: a container, an action unit and a controller. The container is configured to extend from a rear side where a user is located toward a front side where the object is located. An action unit is provided on the front side of the container and configured to drive in such a manner that a mechanical action for mowing or cutting the object can be applied to the object. A controller is configured to execute a program so as to: in a driving step, drive the action unit by controlling a drive output of the action unit to a target value, in a monitoring step, monitor a state or a behavior of the drive output with respect to the target value during the control in the driving step, and in an adjusting step, adjust the target value based on the state or the behavior during the monitoring.

An improved timber jack for raising and supporting logs off from the ground has an elongated lever arm handle member supporting a fulcrum at a distal end of the handle creating a lever of the first class. The novelty resides in having an arcuate fulcrum such that applying a force at a proximal end of the handle causes the fulcrum to roll on the ground as the log is being lifted. Less effort is required to lift a given load as compared to conventional timber jacks.

The present disclosure relates to a chainsaw 1 comprising a housing 3, a guide bar 5, projecting from the housing 3, and one or more handles 9. The guide bar 5 has a main direction of extension 15 defined by its center-line. The housing comprises an outer shell 3 made of plastic, which has at least a first 23 outer groove filled with a contrasting plastic material, wherein the groove at least partly extends straight in a transverse direction 17 that deviates less than 3 degrees from a direction perpendicular to the main direction 15 of extension of the guide bar 5. This provides an indication that facilitates precise and safe felling of trees.

A work implement is provided with a tool that has an opening. A housing part is provided and a stud bolt is screwed into the housing part. The stud bolt fastens the tool to the housing part. The stud bolt projects axially away from the housing part and projects at least partially into the opening of the tool. A transmission element is provided for transmitting transverse forces, acting transversely to the axial direction, from the tool to the stud bolt. The transmission element is a first element made at least partially of a first material with modulus of elasticity of 1 GPa to 80 GPa, or the transmission element is a second element with a spring element at least partially made of a second material with modulus of elasticity of larger than 80 GPa and with a free space for a spring travel of the spring element.

The invention relates to a device, a method and an assembly of parts produced by cutting in a block B of metal or composite material, following a determined trajectory. The device comprises a guide (3) forming said trajectory and a support (chain 9) mounted in the guide in a sliding manner, comprising a lateral blank (23) provided with at least one cutting plate (24) comprising a protruding cutting edge (25) arranged so as to carry out the cutting in a normal direction (26) in relation to the blank.
