Skid Steer Rake Variable Scarifiers Terrain Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current skid steer rakes have fixed scarifiers, requiring manual adjustment and additional attachments for varying depths and processes, leading to inefficiencies and inconsistent results, and often rely on maintenance-intensive hydraulic systems.
Innovation Solution
A skid steer rake with variable scarifiers that can be deployed and retracted during operation, integrated clod-cleaving wheels for soil smoothing, and a cultipacker subframe for adjusting to uneven terrain, allowing for adjustable depth and process modulation without halting operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed scarifiers are used in rake attachments, then the structure is simple and reliable, but the user cannot adjust the depth of scarification or modify the configuration during operation
Solution Approach 1:
The scarifiers are designed to be movable rather than fixed, allowing them to be positioned at different depths and angles during operation. The linkage system enables dynamic adjustment of scarifier depth and orientation without requiring complete disassembly or complex hydraulic systems.
Solution Approach 2:
The scarifier assembly is divided into separate, independently adjustable components that can be positioned and locked at various depths. This segmentation allows individual scarifiers to be adjusted without affecting the entire system, providing versatility while maintaining mechanical simplicity.
2Adaptability or versatility
If multiple attachments are used to accomplish different soil processes, then each process can be performed with specialized equipment, but the overall device complexity and number of components increases
Solution Approach 1:
The rake attachment is designed to perform multiple soil preparation functions including scarification, grading, and leveling through a single integrated system. The adjustable scarifiers and rake tines can be configured for different operations, eliminating the need for multiple specialized attachments while maintaining capability across various soil processes.
3Extent of automation
If hydraulic systems are used to operate rake implements, then automated control and adjustment are achieved, but additional maintenance and energy consumption are required
Solution Approach 1:
The patent replaces hydraulic control systems with a purely mechanical linkage and lever system for adjusting scarifier depth and position. This mechanical substitution eliminates hydraulic pumps, hoses, and fluid management requirements, reducing maintenance needs and energy consumption while maintaining adequate control capability for field operations.

AI summary
The invention provides a skid steer rake capable of adjustment and modulation during use, without any need to halt operation of attached machinery. The skid steer rake is configured with a plurality of scarifiers capable of deployment and retraction during course of use of the device, as well as a landscape rake and a plurality of clod-cleaving wheels. The scarifiers can be latched in various positions depending on the user's needs. The skid steer rake can be operated in a push or pull configuration, if necessary. Another embodiment of the skid steer rake is configured to have clod-cleaving wheels adjustable to the uneven terrain while maintaining contact of the scarifiers and the skid steer rake with the ground surface.
