The disclosure provides a string trimmer. The string trimmer includes a protective shield, a first motor, a blade and a fan. The first motor is arranged on one side of the protective shield, and a first rotation shaft of the first motor penetrates the protective shield to the other side of the protective shield. The blade is arranged on the other side of the protective shield, and the blade is connected with the first rotation shaft. The fan is arranged on the same side as the first motor, and the fan is mounted on the protective shield through a second rotation shaft. Wherein, a rotation speed ratio between the second rotation shaft and the first rotation shaft ranges from 0.5 to 4. With the string trimmer of the disclosure, the rotation speed of the blade and the fan are different.

Systems and methods for growing vegetation are provided. The disclosed systems (100) and methods (1100, 1200) use rotating growth mats (102) and a cutting device (112). The rotating growth mats and cutting device can be coupled to an anaerobic digester (402) to generated methane gas using vegetation grown on the growth mats. The systems and methods may further use C artificial light sources (108) and a nutrients delivery system (110) to assist growth.

A lawn mower has an electrical port that receives current from an alternator powered by the lawn mower engine. The current and voltage sent the electrical port depend on a flywheel and stator arrangement operatively connected to the alternator. The stator may be replaceable or interchangeable to selectively determine the alternator current and voltage output. 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 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 boom mower having a frame, a boom assembly carried by the frame, a cutting mechanism operably engaged with the boom assembly, and at least one translation assembly operably engaged with the boom assembly and the cutting mechanism that moves the cutting mechanism in one or more of the first movement, the second movement, and the third movement. There is a break-away mechanism that enables the cutting mechanism to pivot relative to the at least one translation assembly.

A mower-conditioner includes first and second conditioning rolls, adjustment assembly, and a linkage. The adjustment assembly includes a first member having a first helical surface and a second member having a second helical surface in contact with each other. The linkage is coupled between the at least one adjustment assembly and the first conditioning roll. The rotation of the at least one adjustment assembly about a pivot axis causes the first conditioning roll to move via the linkage, which adjusts the distance between the first and second conditioning rolls.

A system and computer-implemented method for sensing an amount of free water in cut crop material and automatically adjusting an operating parameter of a mower conditioner to optimize the amount of free water. A sensor located at the exit of a conditioning mechanism measures an actual free water content value of the material as it exits the conditioning mechanism, a processor compares the actual value to maximum and minimum values, and if the actual value is outside this range, automatically adjusts an operating parameter, such as a gap between pairs of conditioning rollers, a pressure exerted by the rollers, or a speed of the mower conditioner, to optimize the actual value. Another sensor may be located at the entrance of the conditioning mechanism. The processor may take into account an operator-selectable value weighting the actual free water content versus a dry down time when adjusting the operating parameter.

A lawn care device including a mobile support apparatus, a grass cutting mechanism coupled to the mobile support apparatus and a lawn striping device coupled to the mobile support apparatus. The lawn striping device has a grass contacting member and at least one torsional restraining device coupled to the mobile support apparatus. The torsional restraining device is coupled to the grass contacting member. The torsional restraining device allowing a restrained pivoting of the grass contacting member relative to the mobile support apparatus.

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.
