A sugarcane harvester for harvesting sugarcane including a cutter configured to cut sugarcane into a sugarcane mat and a primary extractor disposed adjacent to the sugarcane mat configured to remove crop residue from the sugarcane mat. An elevator includes a conveyor to move the sugarcane mat to an end of the conveyor and an extractor is operatively connected to the elevator. The extractor includes a fan housing having an arm extending laterally from a sidewall of the fan housing and toward a center of the fan housing. A fan assembly is supported by the arm and is configured to remove crop residue from the sugarcane mat at the end of the conveyor. A cover assembly is fixedly connected to the support arm and subtends a fan of the fan assembly and a portion of the support arm, wherein the cover assembly directs crop debris away from the fan and the support arm.

A stalk puller to be used with or without a mower/shredder utilizes a pair of independently mounted discs converging along their lower edge to grasp and pull stalks from the ground as the stalk puller is moved down the row by a prime mover. At least one of the discs is urged against the other by a spring such that the associated disc may allow rocks and debris to pass between the discs without damage. The spring mounting reduces adjustments due to normal wear as well as damage from debris.

A device and a method for rapidly preparing carbon from straws and recycling and treating flue gas and smoke dust are provided. The device includes a pyrolysis and carbonization chamber and a collection and separation chamber which are communicated with each other through a flue gas inlet. The collection and separation chamber includes a separation area in which a sprayer is disposed. The method includes: introducing straws that are ignited outside into the pyrolysis and carbonization chamber; introducing flue gas produced by the pyrolysis and carbonization chamber in running into the collection and separation chamber via the flue gas inlet, and at least separately treating the flue gas in the separation area in the collection and separation chamber; and introducing the flue gas into the separation area, and converting main component-biomass energy in the flue gas into straw vinegar using the sprayer in the separation area.

A working machine includes a machine body, a front wheel and a rear wheel provided apart from each other in a front-rear direction of the machine body, a working portion provided between the front wheel and the rear wheel and including a power source and a cutter blade capable of being rotated around a rotary shaft by the power source, and a compaction roller provided between the front wheel and the rear wheel.

A mower (1) comprising: a blade (9) that mows grass; a power generation unit (5) that generates a driving force for rotating the blade (9); a housing (7) that covers the blade (9); and a milling unit (10) that subdivides grass mowed by the blade and discharged from the housing (7).

A lawn mower or stand-on powered drivable machine has an electrical port that receives current from an alternator powered by the engine or motor. The port receives a plug from a garment worn by the lawn mower operator. The garment includes one or more thermo-electric elements that are powered from current extending through the port. The thermo-electric (TEC) elements may be resistive heaters to warm the operator or TEC coolers to cool the operator. Furthermore, the garment may include a rechargeable battery that powers the thermo-electric elements when the plug is disconnected from the port.

A striper arrangement (200) for striping a lawn (1) configured to be arranged on a robotic work tool (100). The striper arrangement (200) comprises a striper mat (10) and a holding arrangement (300) for holding the striper mat (10) in contact with a N surface of a lawn (1) and is configured such that the striper mat (10) is movable in upwards and downwards direction; and further configured to bias the striper mat (10) in downwards direction by a biasing force (BF), such that movement of the striper mat (10) in upwards direction is restricted until a counter force (CF) exerted by the striper mat (10) onto the holding arrangement (300) exceeds the biasing force (BF). The counterforce (CF) is the force exerted by the striper mat (10) onto the holding arrangement (300) when the striper mat (10) transits from a convex bent shape to a concave bent shape or vice versa. A robotic work tool 100 comprising a striper arrangement (200) for striping a lawn (1).
