A method obtains a pollution condition of at least one component of a gardening and/or forestry apparatus. The method includes the steps of: obtaining at least one pollution parameter which describes at least one source of pollution prevalent during an operation of the gardening and/or forestry apparatus; obtaining the pollution condition of the component based on the obtained pollution parameter; and outputting and/or transmitting information based on the obtained pollution condition.

An agricultural working device, such as a mulcher, is improved with a working rotor which is driven by a drive shaft and a cutting rail with a cutting edge which can be directed towards the working rotor. Sensors for acquiring parameters of working rotor and/or cutting rail are provided. An electronic control apparatus is provided with at least one encoder to set the cutting rail. A method for setting the position of a cutting rail of a working device, such as a mulcher, relative to a working rotor, is configured in such a way that the rotational speed of a drive shaft and the rotational speed of the working rotor are measured and compared with one another. When a ratio of the rotational speeds differs by a predefined threshold, a change in the position of the cutting rail is brought about.

A plant-trimming apparatus comprises two spaced-apart end plates, a rotatable tumbler, a rotatable reel comprising a reel shaft and reel blades, two bearing blocks, each detachably connected to a respective end plate and rotatably supporting a respective end of the reel, a motor arranged to drive the reel and the tumbler, a bed bar assembly comprising a bed bar and a bed knife, the bed knife being in operative engagement with the reel blade for cutting of plant material from the tumbler, and a manually-operated locking mechanism operable to secure the bearing blocks and the bed bar assembly to the end plates. The apparatus can be easily disassembled for cleaning and re-assembled, without using tools.

An electro-mechanical device cuts plant stems at a desired angle after a stem is inserted into a stem shaft and a sensor triggers activation of a blade along a blade path at a desired angle. A portable device powered by batteries can be used with plantings where they are growing or a powered device can be used for line production or high volume work.

A cutting tool includes a blade having opposing front and back edges and inner and outer ends and defining at least two cutting loops, each cutting loop having a sharpened cutting edge and extending from an opening at the back edge and sloping therefrom toward the front edge and outer end at a loop angle of between about 35 and 55 degrees, the cutting loops each also having a depth from the back edge of between about 0.2 inches and 0.75 inches; and a handle at the inner end of the blade.

A whole plant bucker having a bucking member with sides extending from a base plane to a height, a plurality of slot openings formed within the sides such that the slot openings converge to an input opening, and an angle between the sides and the base plane that is greater than zero. The input opening receives the trunk of a whole plant, and the slot openings receive branches of the plant and strip off plant material as the plant is fed trunk first through the input opening and as the branches move through the slot openings. A floor standing bucking machine and a hingeably closeable bucking tractor attachments are disclosed.
