A combine harvester is provided with left and right main frames that extend in the front-rear direction of a vehicle body, and a threshing device installed between the left and right main frames. The threshing device is provided with a threshing unit that performs a grain removal process, and a sorting unit that is provided below the threshing unit and performs a sorting process of sorting processed articles after the grain removal process has been performed by the threshing unit. A threshing frame included in the threshing unit is mounted on and supported by the left and right main frames, and a sorting unit frame included in the sorting unit is suspended from and supported by the left and right main frames.

A combine harvester is provided with: a threshing device that performs a threshing process of threshing a crop; a grain tank that stores grain obtained by the threshing process; a grain discharging device that discharges grain to be stored in the grain tank to the outside of the vehicle body; a travel driving device that drives travel of the vehicle body; and an engine that serves as a power source. The combine harvester includes a first relay shaft to which power is transmitted from an output shaft of the engine, and the power of the engine is transmitted from the first relay shaft to the grain discharging device and the travel driving device in a branched manner.

The invention provides a power head and a lawn mower. The power head comprises a motor assembly, an energy device and a housing. The motor assembly comprises a motor base and a motor fixed on the motor base. The housing assembly comprises a casing that is assembled with the motor base. The top of the casing is provided with an air inlet that is inclined backward and downward and an air inlet cavity connected to the air inlet. The air inlet and the air inlet cavity are provided with two. The air inlet cavity is a U-shaped structure with an upper opening, and the casing covers the top of the air inlet cavity to form a sealed airflow passage.

An articulated towing apparatus pulls a rotary driven implement in a forward working direction across a ground surface behind a towing vehicle. The apparatus includes a longitudinal frame pivotally connected at a leading end to the towing vehicle by a coupling frame and pivotally connected at a trailing end to a wheeled frame that supports the implement thereon. The coupling frame defines lateral and vertical pivot axes between the longitudinal frame and the towing vehicle. A drive line, connected between a power take-off of the towing vehicle and the implement, includes (i) a longitudinal drive shaft extending at a downward slope, and (ii) an output for connection to the implement that is rotatably supported on the wheeled frame.

Disclosed are apparatus and corresponding and/or associated methodology generally relating to lawn mower security systems and more particularly to providing the ability to safeguard ride-on style lawn mowers against unauthorized cranking of its engine if the mowers have push/pull mower deck or power-takeoff (PTO) switch technology. Per some embodiments, presently disclosed security components may be secured to a PTO or mower deck switch to prevent the ability to position such switch in a disengaged position. Therefore, existing safety and interlock features of the existing ride-on mower otherwise prevent someone from being able to crank the mower, which helps to guard against unauthorized use and/or theft of the equipment.

Discarded weed seeds in the chaff from the sieve of a combine harvester are destroyed by a weed seed destructor section which provides repeated high speed impacts caused by a pair of rotors each mounted in one of a pair of side by side housings which accelerate the discarded seeds onto a respective stator. A straw chopper and spreader section operate on the straw. The weed seed destructor and optionally the straw spreader is mounted so that it can be moved rearwardly away from the sieve to provide operator access between the destructor and the sieve.

A garden tool includes a power assembly comprising an internal combustion engine having a starter motor; a battery pack for supplying power to the starter motor; a connecting rod assembly having two ends; a working head assembly, the working head assembly and the power assembly being respectively arranged at the two ends of the connecting rod assembly; and a handle assembly including two handles. One of the handles is on a left side of the connecting rod assembly, and another of the handles is on a right side of the connecting rod assembly. The battery pack is detachably assembled on at least one of the handles.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The seeds are carried axially of the rotor by a controlled airstream so that they move to an axial discharge location where a discharge fan is mounted. The angle of the discharge around the rotor axis can be changed to direct the seeds to the side of the combine away from a straw chopper, towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.
