Dual Front-Folding Toolbar Assembly for Narrow Row Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seeding tools with multiple ranks face issues with ground following, row pairing, accessibility for maintenance, and transportation due to the lack of space for achieving narrow row spacing on a single toolbar.
Innovation Solution
A dual front-folding toolbar assembly that allows both toolbars to fold towards a hitch assembly, enabling transition between a planting configuration and a transport configuration, with pivotable and slidable sections to optimize row unit placement and reduce width for easier transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple ranks of planting units are used to achieve narrow row spacing, then row spacing is reduced, but accessibility for maintenance and ground following deteriorates
Solution Approach 1:
The toolbar is divided into multiple independent ranks (first toolbar assembly and second toolbar assembly), each capable of being folded independently toward the hitch assembly. This segmentation allows operators to access individual ranks for maintenance while preserving narrow row spacing during operation.
Solution Approach 2:
The toolbar assemblies are made dynamically foldable between planting and transport configurations. During planting, ranks are extended for optimal row spacing; during transport or maintenance, ranks can be folded toward the hitch assembly to improve accessibility and ground following.
2Manufacturing precision
If multiple ranks of planting units are used to achieve narrow row spacing, then row spacing is reduced, but transportation becomes more difficult
Solution Approach 1:
The toolbar assemblies are designed to be dynamically reconfigurable between planting and transport configurations. In the planting configuration, the first and second toolbar assemblies are extended to provide narrow row spacing. In the transport configuration, both toolbar assemblies fold toward the hitch assembly, significantly reducing the overall width and improving transportation efficiency.
3Length of moving object
If toolbar assemblies are folded towards the hitch assembly, then transportation is improved, but row unit placement becomes more complex
Solution Approach 1:
The folding mechanism is segmented into multiple independent components: the first toolbar assembly with its center section and forward side wings, and the second toolbar assembly with its center section and rearward side wings. Each segment can be folded independently toward the hitch assembly, simplifying the overall control while achieving compact transport configuration.
Solution Approach 2:
The folding mechanism uses dynamic pivotal connections between toolbar sections and the hitch assembly, allowing smooth transition between planting and transport configurations. The pivotal coupling enables controlled folding motion while maintaining structural integrity during both configurations.

AI summary
An agricultural assembly that has a frame, a hitch assembly coupled to the frame and configured to selectively couple the frame to a work machine, a first tool bar assembly configured to receive at least one row unit assembly, the first toolbar assembly being foldable in a first direction towards the hitch assembly and a second tool bar assembly configured to receive at least one row unit assembly, the second toolbar assembly being foldable in the first direction towards the hitch assembly. The agricultural assembly is movable between a planting configuration and a transport configuration and both the first tool bar assembly and the second tool bar assembly fold towards the hitch assembly as the first tool bar and second tool bar transition from the planting configuration to the transport configuration.
