Forward-Discharge Mower With Grass Catch Member Behind Front Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lawn mowers that discharge cut turfgrass forward face issues with grass accumulating in the ruts of the front wheels, leading to uncut grass and poor finishing due to inefficient cutting and collection.
Innovation Solution
A lawn mower design with a blade accommodating section located rearward of the front wheels, incorporating grass catch members that guide cut turfgrass away from the wheel ruts and ensure efficient collection and re-cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cut turfgrass is discharged forward, then the ability to finely cut the cut grass is improved, but the cut grass falls into the ruts of the front wheels and is left in lumps, causing uncut grass and poor finishing
Solution Approach 1:
A grass catch member is introduced as an intermediary component between the cutter blade and the front wheel ruts. This member temporarily holds the cut grass on its upper surface, preventing the grass from falling directly into the wheel ruts while allowing it to be collected and re-cut, thus resolving the contradiction between forward discharge capability and reliable cutting completion
2Productivity
If the blade accommodating section is located rearward of the front wheels, then the grass discharge path is optimized for forward discharge, but the grass may still accumulate in wheel ruts without proper collection mechanism
Solution Approach 1:
The grass catch member serves as a mediator that receives cut grass from the rearward-positioned blade accommodating section and prevents it from accumulating in the front wheel ruts, enabling the rearward location to maintain both discharge efficiency and cutting precision

AI summary
A mower that discharges cut turfgrass forward and includes a plurality of wheels, a cutter blade that cuts turfgrass, and a blade accommodating section that accommodates the cutter blade, in which the blade accommodating section is located rearward of front wheels in a traveling direction and includes a grass catch member having an upper surface on which turfgrass cut by the cutter blade stays.
