Front-Folding Toolbar for Planter Transport Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural planters face challenges in balancing field requirements with transportation parameters, as they often become either too wide for transportation or have undesirable distances between the planter and tractor, especially with increasing size and wider row unit spacings.
Innovation Solution
The design incorporates a front-folding toolbar configuration with pivotally connected center and side frames, draft tubes, and a stacking toolbar assembly that allows the implement to be compact in the working position and narrow in the transport position, enabling efficient conversion between operational and transport modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the planter is designed with larger size and wider row unit spacings to accommodate field requirements, then the planting width and row unit capacity are improved, but the lateral width becomes too wide for transportation purposes
Solution Approach 1:
The patent applies a front-folding toolbar configuration where the toolbars are pivotally connected to the center frame, allowing them to be positioned transversely during planting operations and folded longitudinally during transport. This dynamic repositioning enables the planter to accommodate larger row unit spacings in the field while reducing lateral width for transportation, directly resolving the technical contradiction between planting capacity and transportability.
2Length of moving object
If folding planters forwardly and/or rearwardly fold one or more wing frame members to minimize lateral width for transportation, then the transport width is reduced, but the distance between the planter and tractor becomes undesirable in certain field conditions
Solution Approach 1:
The patent segments the planter structure into a center frame and separately pivotally connected left and right toolbars. This segmentation allows the toolbars to be independently positioned - remaining in a transverse configuration during planting to maintain proper distance from the tractor, while being foldable to a longitudinal configuration during transport to minimize lateral width. The pivotal connections enable this segmented, flexible positioning that resolves the contradiction between transport width and operational effectiveness.

AI summary
An agricultural implement which can be configured in a work position and a transport position. The agricultural implement includes a center frame defining a frame axis. The agricultural implement also includes a left toolbar and a right toolbar respectively pivotally connected to the center frame. The agricultural implement also includes a left draft tube and a right draft tube respectively pivotally connected to the left and right toolbars. In the work position the left draft tube is pivotally folded relative to the left toolbar and in the transport position the left draft tube is pivotally unfolded relative to the left toolbar. In the work position the right draft tube is pivotally folded relative to the right toolbar and in the transport position the right draft tube is pivotally unfolded relative to the right toolbar.
