A riding lawn care vehicle may include: (a) a frame to which a pair of front wheels and a rear wheel assembly of the riding lawn care vehicle are attachable; (b) an engine mounted to the frame substantially between the front wheels; (c) a steering assembly having steering levers operably coupled to respective ones of the front wheels of the riding lawn care vehicle via respective hydrostatic drive pumps driven by the engine; (d) a support platform coupled to the frame rearward of the engine to support a standing rider; and (e) a front mount assembly configured to detachably couple the riding lawn care vehicle to an attachment that enables performance of a yard maintenance activity, where (f) a majority of the support platform is disposed rearward of an axis of rotation of the front wheels and forward of an axis of rotation of the rear wheel assembly.

A grass mowing machine for high power applications includes a controller monitoring a total implement load of multiple implements connected to lift arms on a grass mowing machine. The controller determines if the total implement load consistently exceeds available power. If the total implement load consistently exceeds available power, the controller disables at least one but not all of the implements, and provides a signal to at least one but not all of the lift arms to raise the implements.

Systems and methods for cutting grass and other materials using a disk-shaped cutting web. The cutting web has a center portion that is attachable to a rotating shaft adapter. The center portion may be a solid annular disk having a keyed aperture that allows it to be mounted on a spindle of a rotating shaft adapter. The cutting web has multiple strings that are connected to the center portion and extend outward from it in a generally radial direction (away from the center of the disk). The strings intersect with each other to form junctions at which they are joined, thereby forming a web that can be rotated at high speed to perform a cutting function. The strings of the web can have sharp or serrated edges and may be colored to increase the visibility of the web.

Systems and methods for using interchangeable tool attachments in multi-use tools. In one embodiment, a multi-use tool includes a motor, a shaft and a shaft adapter at the end of the shaft. The motor has user controls (e.g., on/off switch or throttle) that control the motor to drive the shaft and cause it to rotate. The shaft may include a rigid tubular outer member with a flexible inner shaft. The shaft adapter is coupled to the end of the rotating portion of the shaft. The shaft adapter has a mounting flange that rotates with the adapter at the end of the shaft. An interchangeable tool attachment is secured to the mounting flange, and rotation of the shaft adapter and mounting flange causes the tool attachment to rotate as well. Many different tool attachments can be interchangeably secured to the mounting flange to provide corresponding, different functions to the tool.

A wheel for a lawn mower robot includes a structure in which grass seeds can be discharged during a rotation of the wheel. Accordingly, grass seeds are shown as the lawn mower robot travels while performing a lawn mowing task. Therefore, a task of mowing the lawn and a task of sowing seeds can be performed in a unified manner. Thus, the lawn can be managed more efficiently.

An apparatus, system, and method of securing attachments to a utility vehicle, particularly a stand-on, zero-turn mower. The apparatus includes an A-shaped mounting assembly having a base with first and second ends and a tubular member extending outwardly from the first end. The tubular member defines a bore that receives a shaft extending from the attachment. The mounting assembly is positioned vertically above a mower deck but on an opposite side of the frame of the mower relative thereto. The second end of the mounting assembly and part of the mower deck are secured to the frame using the same connectors. A hydraulic actuator engages a forwardmost end of the assembly and is actuatable to raise or lower the assembly relative to the frame, pivoting the assembly about the connectors. The attachment and mower deck are substantially simultaneously operable to perform separate landscaping tasks while the mower moves across a surface.
