An autonomous robot lawnmower includes a blade assembly including blades, a drive system to drive the blades through a cutting area having a cutting width, and a lateral blade guard including at least four bars spaced apart from one another by no less than 1 mm and no more than 15 mm. The at least four bars are positioned between the blades and a mowable area when the robot lawnmower is supported on the mowable area. The at least four bars extend across a portion of the cutting width and extending rearward and forward of the cutting area.

A zero-turn vehicle is provided. The zero-turn vehicle includes a frame, an engine supported on the frame and configured to output rotational power, two or more driving wheels rotatably mounted to an underside of the frame, and a guard having a first end and a second end. The first end of the guard is fixedly secured to the frame by a hinge mechanism, and the second end of the guard is configured to engage the frame by a latching mechanism. In a first position, the second end of the guard is engaged with the frame by the latching mechanism, such that the engine is covered by the guard. In a second position, the second end of the guard is disengaged from the frame by the latching mechanism, such that the guard is rotatable about the hinge mechanism so as to expose the engine from the guard.

A protective enclosure or cab for an operator of a walk-behind or mechanical device, such as a snow blower, engine-driven snow thrower, ride-on tractor, or the like, is provided. The protective enclosure or cab includes an inflatable frame structure which supports a plurality of transparent, flexible windows or a single sheet of transparent material such as a curtain. When inflated, the protective cab is detachably coupled to the walk-behind or mechanical device and surrounds an operator of the walk-behind or mechanical device protecting the operator from the environment such wind, rain, snow or the like, while providing an unobstructed view of the surrounding environment. When deflated, the protective enclosure or cab can be folded into a small volume to be placed in a storage device which can be coupled to the walk-behind or mechanical device.

A work vehicle includes: a chassis; a housing carried by the chassis and including a cowl; a power take-off extending through the cowl and configured to connect to a power source; and an attachment movably coupled to the housing and including: at least one driven element coupled to the power take-off; and a shield assembly associated with and covering the power take-off. The shield assembly includes a rigid section defining a first diameter and a flexible section coupled to the rigid section and defining a second diameter that is greater than the first diameter. The flexible section is configured to fit over and maintain overlap with the cowl during tilting of the attachment.

The present invention provides an electric tool comprising a body, an operating component, an output shaft, and a stop mechanism. An arresting disc is disposed on the output shaft, and a groove is formed on the arresting disc; the stop mechanism comprises a protrusion, for example, a pin, which is operable so that the protrusion extends to insert into the groove to lock the output shaft. A stop mechanism of the present invention is easy to operate, delivers good safety performance, and has a relatively simple structure, which allows convenient production and subsequent maintenance. Further, a stop mechanism of the present invention automatically springs back to a non-stop position at which it detaches from the output shaft or the transmission gear of the transmission mechanism when the external force is lost, which prevents possible damage to the output shaft or transmission mechanism when a user starts the electric tool before releasing the stop mechanism.

An agricultural work machine configured to avoid anomalies is disclosed. Agricultural work machines may encounter anomalies, such as obstacles (e.g., tires) or irregularities in the crop (e.g., weeds), which can reduce the quality of the harvested crop. Manually steering the agricultural work machine requires the constant attention of the vehicle operator. Thus, the agricultural work machine is configured to include sensors to generate one or more images (such as images of various regions of the agricultural work machine), an image processing system to process the images and a control unit to avoid the anomalies (e.g., avoid the identified anomalies, to drive in tracks, and/or to stop the agricultural work machine).

A lawn mower plow or accessory warning device for diverting and saving honey bees and other endangered insects. The device components include a plate for removably securing the warning device to the mower deck; a manner for removably connecting and securing the plate to the deck; a warning emitter; and a way for securing a warning emitter to the plate Alternative mechanical designs and light, sound, electro-magnetic force and spray devices are shown as alternative embodiments. The warning device alerts the pollinating bees of the oncoming mower so the bees can survive by flying away and averting their demise by the mower. Alternative devices for warning are sound, light, smoke, spray and Electro Magnetic force/pulse generators placed with the mowers.

A method for the operation of a self-propelled agricultural working machine has at least one working element and a driver assistance system for generating control actions within the working machine. A sensor arrangement for generating surroundings information is provided, and the driver assistance system generates the control actions based on the surroundings information. The sensor arrangement comprises a camera-based sensor system and a laser-based sensor system, each of which generates sensor information regarding a predetermined, relevant surroundings area of the working machine. The sensor information of the camera-based sensor system is present as starting camera images. The starting camera images are segmented into image segments by an image processing system according to a segmentation rule, and the segmented camera images are combined by a sensor fusion module with the sensor information from the laser-based sensor system.
