A method of defining an end travel limit of an electric actuator includes sensing an electric current of the electric actuator while moving the electric actuator from a first position to a second position. A maximum travel current of the electric current sensed during movement of the electric actuator between the first position to the second position is increased by a factor to define a maximum calibration current. The electric current is then sensed while moving from the second position toward an end travel position of the electric actuator. Movement of the electric actuator is stopped at a fault position when the electric current equals the maximum calibration current. The end travel limit of the electric actuator is then defined as a function of the fault position.

A pick-up attachment for a harvesting machine includes a pick-up rotor having pick-up tools for picking crop up from the ground. The pick-up rotor is connected to at least one guide element on the ground that guides the pick-up rotor to the ground. The pick-up rotor along with the at least one guide element is suspended on the machine frame of the pick-up attachment by control arms, so as to swing. Each control arm is connected to the pick-up rotor with one end, in an articulated manner, and to the machine frame with the other end, in an articulated manner, so that during push travel of the pick-up attachment, a push point forming the attack point of a thrust direction vector defined by the control arms is arranged below the contact point that forms between the ground and the guide element, when the pick-up rotor assumes a certain position.

A machine 10 for harvesting horticultural products, in particular leafy vegetables, comprises a support structure 20 mainly extending predominantly along a movement direction M of the machine 10, between a first end 11 and a second end 12; cutting means 30 mechanically associated with said support structure 20, arranged at said first end 11and configured to cut said horticultural products; conveying means 40 mechanically connected to said support structure 20 and extending, along a conveying direction R, between a harvesting portion 41 arranged near said first end 11, and an outlet portion 42arranged near a receiving area of said support structure 20, and configured to convey said cut horticultural products along said conveying direction R; motorisation means 50mechanically associated with said conveying means 40 and configured to move them so as to convey said cut horticultural products; wherein said conveying means 40 comprise a first carrier 60; and a second carrier 70 arranged counter-facing said first carrier 60 by a predetermined distance so as to define an upwards tunnel 80 of said horticultural products; wherein said first and second carriers 60, 70 being arranged inclined with respect to a horizontal plane substantially parallel to the ground; and wherein said first and second carriers 60, 70 extending along said conveying direction R so as to allow a harvesting of said horticultural products along said conveying direction R from a starting height near the ground to a collection height greater than said starting height.

A walk-behind is configurable in a grass catching mode, wherein a debris container is attached to the mower in a grass collecting configuration to permit the collection of grass clippings. The mower may further be configured such that the debris container is stored on the mower in a stowed configuration. The debris container may be partially or fully supported by a handle of the mower when in the stowed configuration.

A mobile platform comprises a header, a biomass processor, and a guidance system. The header is configured to harvest biomass. The biomass processor is configured to compact the biomass into a multitude of compressed biomass pieces. The guidance system is configured to guide the mobile platform at a speed determined by the operating capacity of the mobile platform.

A grass collector is provided with a grass collector body which includes a storage space for storing grass clippings formed inside the grass collector body and a communication air passage having a first end connected to a rear part of the storage space to allow the storage space and the outside to communicate with each other; a duct which has a first end connected to a front part of the grass collector body and guides grass clippings to the grass collector body; and a dustproof net provided in the communication air passage.

A system for collecting biomass for the production of ethanol is disclosed. Also disclosed is a method for collecting biomass. The method comprising: harvesting biomass with a combine, wherein a first portion of the biomass is substantially forced against the ground and a second portion of the biomass passes through the combine and forming bales comprising the second portion of the biomass. According to an aspect, the bales comprise a majority of the second portion of the biomass and a small part of the first portion of the biomass.

A mobile platform biomass harvester has a header, a biomass processor, a storage container, a guidance system, an engine, an electric generator, and a guidance system. The header harvests biomass. The biomass processor includes a shredder, a press, a dryer, and a densifier. The densifier compacts the biomass into a multitude of compressed biomass pieces. The storage container receives compressed biomass pieces from the biomass processor. The guidance system guides the mobile platform at a speed determined by the operating capacity of the mobile platform. The engine generates shaft power. The electrical generator converts the shaft power to electricity to power the guidance system.
