Hydraulic A-Frame Mounting Assembly for Simultaneous Landscaping Tasks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Landscaping vehicles lack a universal connector for securely attaching a variety of attachments to the front end, requiring different connectors for each type of attachment and limiting the versatility of use.
Innovation Solution
A hydraulically operable A-frame mounting assembly that uses existing components to secure attachments to the mower frame, allowing for the simultaneous operation of multiple landscaping tasks without extensive retrofitting of vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different connectors are used for each type of attachment, then each attachment can be securely mounted, but the device complexity and number of components increases
Solution Approach 1:
The patent implements a universal mounting assembly with a single connector design that can accommodate multiple types of attachments (aerators, dethatchers, snow blowers, etc.) through interchangeable mounting plates. Each mounting plate is configured for specific attachment types, but all attach to the same universal connector on the A-frame, eliminating the need for multiple different connectors while maintaining secure mounting for each attachment type.
2Adaptability or versatility
If a universal connector is designed to accommodate all attachment types, then versatility increases, but the ease of manufacture decreases
Solution Approach 1:
The mounting system is segmented into modular components: a universal A-frame connector, interchangeable mounting plates, and attachment-specific interfaces. Each mounting plate is a separate, easily manufactured component that can be produced independently and swapped as needed. This segmentation allows the universal connector to remain simple in design while still achieving versatility through the combination with different mounting plates.
3Ease of manufacture
If existing vehicle components are utilized for mounting, then ease of manufacture improves, but the adaptability to different attachments may be limited
Solution Approach 1:
The A-frame mounting assembly is designed as a universal interface that leverages existing vehicle frame mounting points while providing adaptability for various attachments. The universal connector on the A-frame can accept different mounting plates, each designed for specific attachment types, thus maintaining ease of manufacture by using existing components while achieving versatility through the modular plate system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the secure attachment of various devices to the front end of landscaping vehicles, allowing for simultaneous performance of multiple tasks like mowing and aerating, without the need for extensive modifications to existing vehicles, enhancing operational efficiency and versatility.
Implementation Method 1
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

AI summary
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 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.
