Skid Steer Mounting Structure for Offset and Centered Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing universal quick attach hookup designs for skid steer loaders are not compatible across different manufacturers, requiring users to adapt new machines to fit their existing inventory of attachments, and the transition to the SAE J2513 standard has left older machines with the 1994 narrow-design coupling standard unsupported, necessitating the use of adapter kits.
Innovation Solution
A hookup design that incorporates two pairs of holes sized according to the SAE J2513 standard, allowing for centered and offset alignments, with a wider receiver and side tabs to ensure secure coupling, enabling attachments to be easily switched between alignments without the need for adapter kits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the SAE J2513 standard is adopted for hookup design, then coupling robustness and versatility are improved, but compatibility with older machines using the 1994 narrow-design standard deteriorates
Solution Approach 1:
The hookup design is segmented into multiple alignment options: a first alignment for centered coupling and a second alignment for offset coupling. This segmentation allows the same hookup structure to serve different coupling needs and maintain compatibility across different machine types while achieving robust coupling.
Solution Approach 2:
The hookup design achieves multi-functionality by incorporating both centered and offset alignment capabilities within a single universal interface. This allows the same hookup structure to work with both older 1994-standard machines and newer SAE J2513 machines, eliminating the need for adapter kits and maintaining broad compatibility while providing enhanced coupling robustness.
2Device complexity
If only centered alignment is provided, then coupling simplicity is improved, but operational versatility deteriorates
Solution Approach 1:
The hookup design incorporates dynamic adaptability by allowing the attachment to be coupled in multiple alignments (centered or offset) depending on the operational requirements. The jam structure can engage with the receiver in different positional relationships, enabling the system to adapt between simple centered coupling and versatile offset coupling without increasing structural complexity.
3Adaptability or versatility
If adapter kits are used for older machines, then compatibility is improved, but device complexity and cost increase
Solution Approach 1:
The hookup design achieves multi-functionality by incorporating both centered and offset alignment capabilities within a single universal interface. This allows the same hookup structure to work with both older 1994-standard machines and newer SAE J2513 machines, eliminating the need for adapter kits and maintaining broad compatibility while providing enhanced coupling robustness.

AI summary
A mower-to-skid steer loader mounting structure is affixed to the top panel of a heavy-duty mowing deck. The mounting structure has a top flange, and, a bottom flange. The bottom flange extends between a spaced first and second edge and is formed with a first and second pair of close-together rectangular holes, the first pair being disposed close to the first edge and the second pair closer to the second edge but not as close as between the first pair and first edge. Wherein the outboard hole of the first pair and the inboard hole of the second pair allow the mowing deck to be mounted offset relative the skid steer loader, while the inboard hole of the first pair and the outboard hole of the second pair allow the mowing deck to be mounted centered relative the skid steer loader.
