A device for harvesting asparagus growing from a asparagus field that includes a frame displaceable over the asparagus field by a drive means in which frame is at least provided with cutting means for cutting the asparagus to be harvested close to the surface of the field, and stabilizing means for stabilizing the asparagus relative to the cutting means.

An outdoor power unit, such as a mower or snow thrower, having a supplemental battery charging station mounted thereon is provided. The outdoor power unit utilizes a flywheel/alternator arrangement to output a selected voltage. The voltage is directed to the supplement battery charging station. The supplemental batteries are thereby charged at the charging station as the outdoor power unit is driven forward or in another direction. The outdoor power unit also includes a rack (which may be in the form of a hook) to carry a battery powered supplemental lawn maintenance tool, such as a weed trimmer, hedger, edger, or leaf blower, amongst others.

A mower having a supplemental battery charging station mounted thereon is provided. The mower utilizes a flywheel/alternator arrangement to output a selected voltage. The voltage is directed to the supplement battery charging station. The supplemental batteries are thereby charged at the charging station as the mower is driven forward or in another direction. The lawn mower also includes a rack (which may be in the form of a hook) to carry a battery powered supplemental lawn maintenance tool, such as a weed trimmer, hedger, edger, or leaf blower, amongst others.

An agricultural working device, such as a mulcher, is improved with a working rotor which is driven by a drive shaft and a cutting rail with a cutting edge which can be directed towards the working rotor. Sensors for acquiring parameters of working rotor and/or cutting rail are provided. An electronic control apparatus is provided with at least one encoder to set the cutting rail. A method for setting the position of a cutting rail of a working device, such as a mulcher, relative to a working rotor, is configured in such a way that the rotational speed of a drive shaft and the rotational speed of the working rotor are measured and compared with one another. When a ratio of the rotational speeds differs by a predefined threshold, a change in the position of the cutting rail is brought about.

A lift-suspended mower for an agricultural vehicle. The lift-suspended mower includes a frame, one or more cutting devices that are movably mounted with respect to the frame for cutting crop material on a ground surface, a first wheel mounted to the frame for contacting the ground surface and supporting the frame above the ground surface, and a first suspension system interconnecting the first wheel to the frame. The first suspension system includes (i) an actuator that is selectively actuable to either raise or lower to a predetermined degree the first wheel relative to the frame or vice versa, and (ii) a device for permitting the first wheel to move toward the frame when a pressure exerted by the first wheel onto the ground surface increases, wherein the device operates independently of the actuator.

A harvester has a main frame defining a front and a rear, and an inlet for receiving first portions of a crop. The inlet is disposed proximate the front of the main frame. The harvester also includes a separator for processing the first portions, at least one outlet downstream of the separator for ejecting the processed first portions, a boom extending proximate the front of the main frame for reaching un-processed crop, and a topper coupled to the boom for cutting second portions of the crop. The topper includes a cutter for cutting the second portions, a conveyor for receiving the second portions from the cutter, and an outlet disposed proximate the conveyor. The conveyor is configured to transport the second portions towards the outlet for ejecting the second portions towards the field.

Provided is a mower unit mountable to a traveling vehicle body. The mower unit includes a mower deck, a plurality of blades supported to the mower deck to be rotatable about vertical rotational axes, and a rear vacuum plate disposed rearwardly of rotational locus circles of the plurality of blades and attached to a lower face of the mower deck. The rear vacuum plate includes a plurality of arcuate portions formed arcuate to extend along the respective rotational locus circles of the blades and a convexly curved portion curved to extend into a triangular gap portion formed between two adjacent rotational locus circles, the convex curved portion bridging opposed ends of two adjacent arcuate portions. The convexly curved portion and the arcuate portions are connected to maintain a continuous curve.

A tractor assembly includes a tractor having a first set of wheels and a second set of wheels, a mower-conditioner assembly coupled to the tractor, a shield coupled to the conditioner at a location rearward thereof, and a crop moving assembly coupled to either the tractor or mower-conditioner assembly. The mower-conditioner assembly includes a mowing mechanism configured to cut a crop and a conditioner configured to crimp the crop. The shield deflects the crimped crop rearwardly therefrom and forms a windrow of a first width. The windrow is disposed directly behind the tractor and includes a device for spreading the windrow in at least one direction to form a second width. The second width is greater than the first width.

A system and method for an autonomous lawn mower comprising a mower body having at least one motor arranged to drive a cutting blade and to propel the mower body on an operating surface via a wheel arrangement, wherein the mower body includes a navigation system arranged to assist a controller to control the operation of the mower body within a predefined operating area, wherein the mower body further includes a signal detecting module arranged to detect a signal representative of a navigational marker.
