摘要： A chopper system and method for cutting crop material with a rotating first drum having first blades and a counter-rotating second drums having second blades. Blade pairs with one first blade and one second blade contact one another and cut the crop material. The blades of each blade pair contact one another for at least ten degrees of rotation. The blades can have beveled cutting edges, and the blade pairs can make bevel to bevel contact. The initial contact of the blade pairs during each rotation can form a swipe angle of 15 degrees or less. The initial contact of the blade pairs during each rotation can have the acute end of the first blade contact the second blade near the middle of the beveled edge. During each rotation, the acute end of the second blade can contact the back of the first blade.

摘要： A walk reel mower has a pivotal rear traction drum that can be selectively disposed in two different mowing positions that allow a single mower to cut grass on golf course greens as well as tee boxes with no degradation in cutting or power performance. The reel cutting unit has a pivotal rear shield to allow the rear shield to be pivotally adjusted to maintain its radial spacing relative to the orbit of the reel at a desired amount as the reel diameter decreases due to wear. The ground speed of the walk reel mower is automatically slowed during turns of the mower by a mechanical cable assembly that links a user operable throttle control and throttle reducing control to a prime mover throttle. Finally, the leverage provided by the mower handle assembly when placed in a lowered position is used by the user to more easily deploy a kickstand.

摘要： A blade cartridge for a horizontal rotary mower includes airfoil blades and diverter blades that alter airflow within the blade cartridge and prevent grass clippings from accumulating. The horizontal rotary lawnmower may be adapted to engage a cleaning station with brushes or cleaning pads to remove grass clippings while the horizontal rotary lawnmower blade assembly is operated in reverse. The cleaning station may automatically engage a reverse operation. The cleaning station may also hone the blades of the blade assembly while operating in reverse.

摘要： The invention relates to a device for comminuting, collecting and transporting of comminuted material, comprising a frame that is designed to be supported by a vehicle, a tool carrier rotor that is accommodated by the frame by means of an axis that is substantially parallel to the treated bottom and perpendicular to the driving direction of the vehicle, a drive that moves a shaft which is kinematically connected to the tool carrier rotor, and a cover that surrounds the tool carrier rotor on the upper side and that is connected to a feed channel. According to the invention at least one blower is provided in the cover and/or in the channel, which blower supports the flow of the material crushed by the tool carrier rotor, wherein at least two blowers are provided that are parallel to one another, that rotate in opposite directions, and that have a common chute.

摘要： A lawnmower with a plurality of blade holding elements in a horizontally rotating blade assembly holds a plurality of replaceable blades in a blade channel. The blade assembly is covered by a blade assembly guard that is only open underneath at a point where blades in the blade assembly would cut grass during normal operation. A blade assembly access panel in the upper portion of the blade assembly guard allows blades to be easily replaced.

摘要： In a mower of the cross-flow blower type the rotor of the blower has a plurality of sections with predetermined blades of at least two adjacent sections of opposite helix angle and having cutting edges which overlap in the axial direction and are angularly spaced about the rotor axis in the overlap region, thereby producing counteracting axial components of air velocity. Preferably at least one blade in each section is shorter than the rotor length and advantgeously all blades in a section are shorter, with ends angularly spaced from and overlapping the ends of the blades of adjacent sections. Preferably each section has blades of opposite helix angle to produce counteracting components of air velocity in each section. Advantgeously each section of the rotor is formed of an integral sheet bent to form end supports and a pair of blades of opposite helix angle. The blades are preferably of the hook type with the leading edges of the hooks serrated. Marked reduction in blower noise can be attained, with good mower performance.

摘要： A power rake attachment for a power sweeper includes a rake assembly composed of rake half sections with each half section having two shaft clamping members with semi-circular loop portions. The half sections are assembled around the power shaft without removal of the shaft by securing the clamping members in opposed relationship around the shaft with bolts. The clamping members of each half section are interconnected by cross bars which carry spaced ground engaging tines.
