A crop row mower incorporating an “L” member having a column and having a foot, the column having upper and lower ends, and the foot having a distal end; a wheel connected operatively at the distal end of the foot; a first rotary blade mounted at the lower end of the column; a hydraulic motor mounted at the upper end of the column; a first drive shaft extending along the column, the first drive shaft operatively interconnecting the hydraulic motor, and the first rotary blade; and a mounting bracket fixedly attached to the column's upper end, wherein the mounting bracket is adapted for pushing or pulling the “L” member in a proximal direction.

The permanent lawn mower, or inground lawn mower, is designed to be an alternative to conventional mobile mowing. Its focus is small grassy areas that are dangerous or impractical to mow by other means. In a first embodiment, the system includes three primary components: a drive unit that supplies rotational motion; a cable that carries rotational motion away from the drive unit, and one or more cutting heads that convert the rotational motion into a cutting action. In a second embodiment, the drive unit is combined with the cutting head, avoiding the need for a cable to carry rotational motion.

A stalk puller to be used with or without a mower/shredder utilizes a pair of independently mounted discs converging along their lower edge to grasp and pull stalks from the ground as the stalk puller is moved down the row by a prime mover. At least one of the discs is urged against the other by a spring such that the associated disc may allow rocks and debris to pass between the discs without damage. The spring mounting reduces adjustments due to normal wear as well as damage from debris.

A haulm cutting apparatus includes lateral and vertical guiding means or surfaces and a first, rotatable shear rotatable around an axis of rotation extending in a direction with a vertical component. The apparatus further includes a counter shear for cooperation with the first, rotatable shear, and the first, rotatable shear and the counter shear are positioned in a side-by-side relationship relative to a direction of travel during operation.

A cutting disc for a machine for harvesting stem-like plants includes a number of elements which together can be attached or are attached to a bracket forming a circular ring with an outer cutting edge. At least one of the elements is attachable to the bracket in a first position, in which a first edge of the element forms the outer cutting edge, and in a second position, in which a second edge of the element forms the outer cutting edge. No matter whether the element is in the first of second position, a circular cutting edge is made up.

Providing objective analysis of performance results of power equipment devices are detailed throughout this disclosure. Image data of vegetation cut by a power equipment device can be captured and uploaded to a server for analysis. Data pertinent to the performance results, such as environment conditions, mechanical parameter settings, type of vegetation or turf, and so forth can be submitted with the image data in some disclosed aspects. Analysis results, optionally in conjunction with adjustment data for adjusting mechanical settings of the power equipment can be provided in response to the image data.

A striper arrangement (200) for striping a lawn (1) configured to be arranged on a robotic work tool (100). The striper arrangement (200) comprises a striper mat (10) and a holding arrangement (300) for holding the striper mat (10) in contact with a N surface of a lawn (1) and is configured such that the striper mat (10) is movable in upwards and downwards direction; and further configured to bias the striper mat (10) in downwards direction by a biasing force (BF), such that movement of the striper mat (10) in upwards direction is restricted until a counter force (CF) exerted by the striper mat (10) onto the holding arrangement (300) exceeds the biasing force (BF). The counterforce (CF) is the force exerted by the striper mat (10) onto the holding arrangement (300) when the striper mat (10) transits from a convex bent shape to a concave bent shape or vice versa. A robotic work tool 100 comprising a striper arrangement (200) for striping a lawn (1).

A track-type moving device having one or more track mechanisms. The track mechanism may include a guide wheel, a driving wheel, a track, and/or a tensioning mechanism. The tensioning mechanism may include an adjusting member and/or an elastic member. The elastic member may provide a driving force that enables the adjusting member to move.
