A vegetation cutter for cutting vegetation circumferent an obstacle. The vegetation cutter comprises a frame comprising a dock for receiving the obstacle; at least one cutter that is moveable in a cutting trajectory whereby vegetation circumferent a docked obstacle is cut; and a driver for moving the at least one cutter in the cutting trajectory. A method for cutting vegetation circumferent an obstacle.

A method for mowing around an obstacle. A mower arm is pivotally connected to a supporting member supportively connect to a supporting vehicle. A pivotal arm is pivotally connected to the mower arm. A cutter head is connected to the pivotal arm, the cutter head comprising a first cutter and a second cutter. A release mechanism comprising a holding plate is located on the pivotal arm and an actuator is located on the mower arm, the holding plate comprising at least one hole, the actuator engaging the at least one hole in the holding plate to hold the pivotal arm in a first position such that the first cutter is in a relatively leading position to the second cutter.

An apparatus for mowing grass. The apparatus has a plurality of cutting devices for mowing the grass. The apparatus has a plurality of carrying arms which are arranged offset with respect to one another with regard to the transverse axis of the apparatus, and are supported such that they can be pivoted up and down in each case individually, and carry in each case one of the plurality of cutting devices. The apparatus has a plurality of supporting elements which support in each case one of the plurality of carrying arms on an underlying surface, and are arranged in front of the respective cutting device with regard to a forward moving direction of the apparatus. The apparatus can have the advantage that the leading supporting elements do not push any cuttings in front of them, and a risk of the apparatus being jacked up is decreased.

A three headed cutter is comprised of a cover assembly under which are located the three cutting head assemblies. The cover assembly, along with the cutting head assemblies, are designed so as to rotate around impediments, the cover assembly pivots around a central axis. The three headed cutter has a connecting member which connects it to the tractor by way of an articulated boom arm. The boom arm connects with the connecting member at a pivot point, from which a biasing means is also connected. The biasing means and pivot point allow for the cover assembly to take in the shock of hitting an impediment by having the boom arm move at its pivot point so as to move the cover without damage just before the start of its rotation around the impediment. Each of the three cutting head assemblies consists of a twin blade member and a caster. The caster rotates with the cutting head assemblies. The cover assembly is further supported by a support wheel which takes on the load from the connecting member and the articulated boom arm. The central axis has a motor from which extends downwardly a shaft member, which itself connects to a multiple track pulley which has three belts, one for each cutting head pulley, which themselves connect directly to the cutting head by way of a short shaft member. Tension pulley assemblies, which consist in a pulley and biasing means assembly, keep tension on the belts.

Disclosed are solutions for an autonomous vehicle to real-time detect and determine dynamic and/or obscured obstacles to support navigation and services to within a desired proximity of said obstacles. Certain such implementations are specifically directed to autonomous mowers, for example, capable of real-time object detection to determine location and orientation of solar panels in a solar farm, for example, and based on the location and orientation of such solar panels further determine the location of their corresponding posts that may be otherwise obstructed from direct detection by the autonomous mower's other sensing systems possibly due to vegetation growth around the posts or other reasons.

A lateral offset mower implement may include a mower support frame, a pivot head, a curtain support apparatus, and a curtain. The mower support frame has a first end attached to a work vehicle and a second end spaced from the first end along a central longitudinal axis of the mower support frame. The pivot head is coupled to the mower support frame proximate the second end thereof. The pivot head defines a first curtain axis, and the first curtain axis is vertical during operation. The curtain support apparatus has a primary curtain support member attached to the pivot head and extending away from the pivot head to a distal end. The curtain is supported by the curtain support apparatus. The primary curtain support member is pivotably attached to the pivot head for relative rotation between the primary curtain support member and the pivot head about the first curtain axis.
