Universal Tractor Frame for Multi-Implement Hitch Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tractor implements require separate frames and attachment structures, leading to the need for multiple implements and increased storage space and costs.
Innovation Solution
A universal implement frame that connects to a tractor's three-point hitch or drawbar, allowing conversion between work functions by adding or removing parts, reducing the need for multiple dedicated frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate frames and attachment structures are used for each tractor implement, then each implement can be optimized for its specific function, but the number of implements required increases, leading to increased storage space requirements and costs
Solution Approach 1:
The patent applies universality by designing a single frame structure that can accommodate multiple different working implements through standardized mounting points and attachment mechanisms. The frame serves multiple functions: it provides structural support, enables attachment of various implements (box blades, grader blades, mower/cutters, tillers, cultivators, disc harrows, aerators, rippers, seeders), and connects to the tractor via three-point hitch or drawbar. This eliminates the need for separate dedicated frames for each implement type.
2Reliability
If separate frames and attachment structures are used for each tractor implement, then each implement has a dedicated structure, but storage space requirements increase significantly
Solution Approach 1:
The universal frame reduces storage space by consolidating multiple implement-specific frames into one shared structure. The frame maintains reliable attachment through standardized mounting points that securely hold each implement type while occupying only one storage location rather than multiple separate locations for each implement-frame combination.
3Adaptability or versatility
If separate frames and attachment structures are used for each tractor implement, then each implement is optimized for its function, but the cost and weight of individual implements increase
Solution Approach 1:
The patent extracts the frame structure from each individual implement and creates a separate, shared universal frame. This separates the structural support function from the working components, allowing the frame to be shared across multiple implements. Each implement only needs its specific working components and minimal attachment hardware, significantly reducing the weight of individual implements while maintaining functional adaptability.

AI summary
A universal tractor implement frame for attaching to the three point hitch or drawbar of a tractor including two longitudinal beams, two transverse struts arranged between and perpendicular to the two longitudinal beams, and two longitudinal stabilizers. Forward and Rear sets of frame legs are attached to the forward and rear struts, respectively and are configured to connect at their distal ends to the upper link of the tractor's three point hitch or drawbar. Connection plates are attached to the forward strut for connecting to the two lower links of the tractor's three point hitch or stabilizers. Various working tools may be attached to the beams, stabilizers, and/or to the struts of the universal frame for carrying out the work of prior art tractor implements.
