The present invention relates to a no-till stem and root extractor system that has directionality, extracting the root ball from the soil. A conveyor chain crop remnant extractor assembly has a pair of flexible conveyor chains, a pair of coupling conveyor arms, two pairs of rotatable wheels, a pinch cylinder, and a plurality of cross-slat bars. As the device moves along the crop remnants, the pair of flexible conveyor chains, guided and retained by the two pairs of rotatable wheels, pull the stalks and root balls from the earth, pinch, and pulverize the complete crop remnants.

A mower can dynamically adjust the cutting height of a mower deck based on a mower's location. As a mower travels over an area of grass to be cut, a control system can track the current location of each mower deck on the mower. The control system can compare the current location of a mower deck to a boundary of one or more sections defined within the area to thereby determine which section the mower deck is within. When the control system detects that a mower deck has crossed or will cross into a section, it can identify a particular cutting height assigned to the section and dynamically adjust the cutting height of the mower deck to the particular cutting height. When a mower includes more than one mower deck, the control system can be configured to independently adjust the cutting height of each mower deck based on its location.

A mower blade assembly attaches to a rotatable spindle and includes a mounting plate which defines a first pin aperture. The mounting plate and a retaining plate are attached to the rotatable spindle. The retaining plate defines a second pin aperture. A movable pin plate comprises a pin. A blade is selectively attachable to the mounting plate. The blade defines a retaining plate aperture and a third pin aperture. A biasing member urges the movable pin plate from a disengaged position to an engaged position. The pin is engageable with the pin apertures for mounting and retaining the cutting blade to the mounting plate. The blade is attached by moving the blade over the retaining plate aperture, urging the movable pin plate to the disengaged position, rotating the blade, and releasing the movable pin plate. Another embodiment includes a force finger.

A local coordinate system in which the turfed area is digitized, and a marking area is divided into elementary cells to form a matrix, and the pattern to be marked is broken down into a mosaic of pixels associated with the elementary cells of the matrix. Next, for each elementary cell of the matrix, tasks to be performed by the marking devices are determined according to a value of the pixel associated with said elementary cell, to mark the pattern to be marked on the marking area; and the movement of the vehicle over the turfed area is controlled so as to cover all of the elementary cells, and the marking devices are controlled so as to perform the tasks to be performed in each elementary cell.

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 verge-cutting mower device (20, 30), for example for maintaining roadside verges, has at least one frame (16) intended to be mounted on an automotive agricultural machine (10) and on which there is mounted a piece of cutting/grinding equipment (20) intended to mow or grind plants. The cutting/grinding equipment (20) is actuated using an electric motor (33).

Some crops, such as soybeans, grow close to the ground, having a low canopy relative to that of weeds growing interspersed in the crop. A farm implement removes weed growth above the crop canopy. The implement has a chassis with at least three wheels connected to the chassis, a cutting mechanism, mounted at a front end of the chassis, a means for collecting weed growth cut by the cutting mechanism, mounted on the chassis, means for generating and selectively applying rotational torque to at least one of the at least three wheels and means for a user to guide the chassis down the rows in which the crop is grown.

An improved advertising system can include a location having a substantially large expanse of living greenery, a predetermined design for an advertisement, and a chlorophyll-based agent. The location can be observable by viewers at a predefined minimum viewing distance. The chlorophyll-based agent can be used to paint the predetermined design on the living greenery. The chlorophyll-based agent can be non-detrimental to the health of the living greenery. The predetermined design painted on the living greenery with the chlorophyll-based agent can be only viewable by viewers at the predefined minimum viewing distance. Living greenery treated with the chlorophyll-based agent can be visibly distinguishable from and shinier than neighboring untreated living greenery. When a viewer is nearer than the minimum predefined viewing distance, a difference in shine and color between the treated living greenery and the untreated living greenery can be substantially unnoticeable.
