Two-Stage Mower Layout for Overgrown Vegetation and Finish Cut
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lawn mowers are inadequate for thick, overgrown vegetation, requiring multiple machines or incomplete maintenance, leading to increased labor and time costs.
Innovation Solution
A vehicle equipped with a two-stage cutting system, comprising a flail mower for coarse cutting and a rotary mower for finishing, allowing a single machine to perform both stages effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional brush hog is used to clear thick, overgrown, or tall vegetation, then the vegetation can be cleared effectively, but the finishing cut quality is insufficient
Solution Approach 1:
The cutting system is segmented into two distinct stages: a first cutting configuration (brush hog) for coarse cutting of thick, overgrown, or tall vegetation, and a second cutting configuration (finishing blade setup) for providing a quality finishing cut. This segmentation allows each stage to be optimized for its specific function, resolving the contradiction between vegetation clearing capability and finishing cut quality.
Solution Approach 2:
The patent combines both the brush hog cutting configuration and the finishing blade setup into a single vehicle, integrating two previously separate machines. This merging allows the vehicle to perform both coarse cutting and finishing cut functions simultaneously, eliminating the need for a second vehicle while maintaining both productivity and cut quality.
2Manufacturing precision
If a second vehicle with a finishing blade setup is used to follow the brush hog, then more complete maintenance is achieved, but labor and time costs increase
Solution Approach 1:
The patent merges the functions of two separate vehicles (brush hog and finishing mower) into a single integrated vehicle. The vehicle includes both a brush hog with rotary blades for coarse cutting and a finishing blade setup for quality finishing cuts, allowing one operator to perform complete maintenance in a single pass, thereby reducing labor and time costs while maintaining high maintenance quality.
Solution Approach 2:
The single vehicle is designed with multi-functionality, capable of performing both coarse vegetation clearing and precision finishing cuts. This universal design eliminates the need for multiple specialized vehicles and operators, reducing both time loss and labor costs while achieving complete maintenance.
3Ease of manufacture
If only a brush hog is used to maintain the field, then cost effectiveness is improved, but maintenance completeness deteriorates
Solution Approach 1:
The patent combines the brush hog and finishing mower into a single vehicle, making the more complete maintenance capability cost-effective by eliminating the need for a second vehicle and operator. This integration maintains the cost effectiveness of using a single vehicle while achieving the maintenance completeness previously requiring two vehicles.
Solution Approach 2:
The vehicle is designed with universal cutting capabilities that include both coarse cutting for thick vegetation and finishing cut capabilities. This multi-functionality allows a single vehicle to provide complete maintenance, making comprehensive field maintenance cost-effective without sacrificing maintenance completeness.

AI summary
A system and method according to one embodiment are provided in a vehicle to perform a two-stage cut of grass or other vegetation in a field or lawn. The first stage may be a coarse cut stage, and the second stage may be a finish cut stage. The first and second stages may be conducted by separate cutting configurations. For instance, the first cutting configuration or coarse cutting configuration may be a flail mower configuration, and the second cutting configuration or finish cutting configuration may be a rotary cutting configuration.
