Four-Part Tractor Implement for One-Pass Soil Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Preparing a field for planting is time and labor intensive, often requiring multiple passes and slow tractor movement, especially in wet conditions, and typically involves pre-treating existing vegetation before plowing.
Innovation Solution
A four-part tractor implement system comprising a ripper with angled ripper arms, a roller with angled blades, and finishing apparatuses like discs and baskets, which can work the soil efficiently at higher speeds without needing weed treatment, aerating and mulching vegetation into the soil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional plowing implements are used, then soil preparation can be achieved, but the process is time-consuming and requires slow tractor movement at 3-5 mph
Solution Approach 1:
The implement is divided into four distinct functional sections: a ripper section with vertical shanks for deep soil penetration, a tilling section with curved blades for breaking up soil clods, a vegetation management section with cutters for handling plant material, and a finishing section with levelers for surface preparation. Each section performs a specific function that contributes to overall efficiency, allowing the system to work faster while maintaining quality preparation.
Solution Approach 2:
The patent combines multiple soil preparation functions into a single integrated implement that can perform ripping, tilling, vegetation management, and finishing operations simultaneously in one pass. This merging of functions eliminates the need for multiple separate passes and implements, thereby increasing productivity and reducing time loss while maintaining thorough soil preparation quality.
2Productivity
If traditional implements are used on wet ground, then soil can be prepared, but the process becomes even more difficult and time-consuming
Solution Approach 1:
The implement features locally optimized components for different soil conditions. The ripper section has vertically-oriented shanks specifically designed to penetrate and aerate compacted wet soil effectively. The tilling section includes curved blades that can handle sticky wet clods, and the vegetation management section has cutters capable of managing wet plant material. These localized design features make the overall system much easier to operate on wet ground compared to traditional implements.
3Manufacturing precision
If multiple passes are made for complete soil preparation, then adequate soil working is achieved, but time and labor requirements increase significantly
Solution Approach 1:
The implement integrates four distinct soil preparation functions into one unified system that can complete all necessary operations in a single pass. The ripper section breaks up compacted layers, the tilling section processes soil clods, the vegetation management section handles plant material, and the finishing section prepares the surface. This combination ensures complete soil preparation quality without requiring multiple separate passes, thereby doubling or tripling productivity compared to traditional multi-pass approaches.
Solution Approach 2:
The ripper section performs preliminary deep penetration and aeration of the soil before the subsequent tilling and finishing sections process the material. This preliminary action of breaking up compacted layers and incorporating vegetation ahead of time allows the remaining sections to work more efficiently, ensuring complete soil preparation in one continuous pass rather than requiring multiple sequential operations.
4Ease of operation
If separate weed treatment is applied before plowing, then vegetation can be controlled, but additional time and labor are required
Solution Approach 1:
The implement merges vegetation management capabilities directly into the soil preparation system. The vegetation management section with specialized cutters and processors is integrated alongside the ripping and tilling sections, allowing plant material to be cut, shredded, and incorporated into the soil simultaneously with the soil preparation operations. This eliminates the need for separate pre-plowing weed treatment passes, saving significant time and labor while maintaining effective vegetation control.
Solution Approach 2:
Instead of removing vegetation before plowing as a separate preparatory step, the system converts the vegetation into a beneficial component by cutting, shredding, and incorporating it into the soil during the main preparation pass. The plant material becomes organic matter that improves soil structure and fertility, transforming what was previously a nuisance requiring separate treatment into an asset that enhances soil quality, thereby eliminating additional time and labor requirements.

AI summary
Tractor implements can work the ground in a proper and efficient manner to ensure the ground is ready for planting. The tractor implements can be arranged in various, specific manners, in series behind a tractor, depending on field conditions. For example, the tractor may pull a single disc positioned ahead of each ripper disposed on a ripper implement. Behind the ripper, a roller implement may be disposed for lifting, rolling and breaking up the soil. An optional disc may be provided forward of each roller blade assembly. Behind the roller implement, one or more finishers, such as a disc, a multi-disc, a chopper, a basket, a double basket, a knife, a deflector, or the like, may be used to finish the worked soil. Soil prepared by such implements have been shown to significantly increase crop yield.
