Roller Basket Finishing Attachment for Tillage Implements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tillage implements face challenges in maintaining efficient ground engagement and residue flow due to issues with tool orientation, alignment, and folding mechanisms, leading to obstacles during transport and operation.
Innovation Solution
The design incorporates a finishing attachment with a support arm and cross-bar system that allows for pivotal movement, anti-tangle brackets, and adjustable downforce mechanisms, along with an offset disk gang arrangement to enhance ground-following capabilities and reduce frame depth, facilitating better residue flow and folding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the implement uses a hinged wing configuration for folding, then transportability is improved, but tool entanglement and folding complexity increase
Solution Approach 1:
The implement is divided into a main frame and separate hinged wings that can fold independently. Each wing is segmented with its own hinge mechanism allowing it to fold inward separately, reducing the overall complexity of the folding system while maintaining transportability.
Solution Approach 2:
The finishing attachment is extracted and mounted on the rear of the main frame, separate from the hinged wings. This extraction allows the wings to fold without interference from the finishing tools, eliminating entanglement issues while preserving the folding capability for transport.
2Productivity
If the implement maintains extended wing configuration for ground working, then ground coverage is improved, but frame depth and transport size increase
Solution Approach 1:
The wings are designed with dynamic folding capability, allowing them to transition between an extended operational configuration for ground working and a retracted transport configuration. This dynamic adaptation enables the implement to achieve both extended ground coverage during operation and reduced frame depth for transport.
3Reliability
If the support arm is positioned far from the frame for better ground following, then ground engagement is improved, but folding clearance and tool entanglement increase
Solution Approach 1:
The support arm and finishing attachment are extracted from the traditional wing-mounted position and relocated to the rear of the main frame. This extraction positions the support arm away from the folding wings, providing sufficient clearance during folding operations while maintaining effective ground following capability during operation.
Solution Approach 2:
The support arm is positioned in a different spatial dimension relative to the wings, mounted on the rear frame rather than on the wings themselves. This dimensional repositioning allows the support arm to maintain its ground-following function while avoiding interference with the folding wings, eliminating entanglement.
4Device complexity
If the roller basket is fixed to the cross-bar, then structural simplicity is improved, but ground following and orientation adjustment are limited
Solution Approach 1:
The roller basket is mounted with a pivot connection to the cross-bar, allowing it to rotate and pivot dynamically in response to ground conditions. This dynamic mounting enables the roller basket to adjust its orientation and follow the ground profile, improving ground following capability while maintaining relatively simple structural connections.

AI summary
A finishing attachment for a tillage implement has a support arm configured to mount to the frame so that a long dimension of the support arm extends in a fore-aft direction of the implement. A cross-bar having a long dimension extending transverse to the fore-aft direction is coupled to a free end of the support arm. A roller basket is mounted to the cross-bar for rotation with respect to the cross-bar. A pivot bracket couples the free end of the support arm to the cross-bar. The pivot bracket forms a pivot axis extending substantially in the fore-aft direction of travel about which the roller basket pivots.
