Grass Collector Front Bottom Plate Horizontal Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grass collectors with a two-section construction, where only the rear container section is pivoted upward, have a limited collecting capacity due to the sloped bottom of the front container section, which restricts the overall collecting volume.
Innovation Solution
A grass collector design featuring a front container section with a substantially horizontal bottom plate and a rear container section pivotably supported about a pivot point in the rear upper region, allowing the rear section to cover the front section's opening and pivot to allow cut grass to fall, thereby increasing the collecting volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the front container section has a sloped bottom portion, then the weight to pivot is reduced, but the collecting capacity is limited
Solution Approach 1:
The grass collector is divided into two separate container sections: a front container section with a sloped bottom for efficient discharge, and a rear container section with a substantially horizontal bottom plate for increased collecting capacity. The rear section can be pivoted independently about a pivot point located in the upper rear portion of the front container section, allowing each section to be optimized for its specific function while working together as a unified system.
2Ease of operation
If the entire collector is swung upward, then the discharge function is achieved, but the weight to pivot increases
Solution Approach 1:
The collector is segmented into two independently pivotable sections. Only the rear container section needs to be pivoted upward for discharge operations, significantly reducing the weight that must be moved compared to pivoting the entire collector. The front container section remains stationary or can be independently managed, optimizing the ease of operation while minimizing the effort required.
Solution Approach 2:
The system transitions from a static, monolithic collector structure to a dynamic, modular configuration where the rear container section can be independently pivoted. This dynamic segmentation allows the operator to discharge grass by moving only the necessary portion of the collector, improving operational efficiency and reducing physical effort.

AI summary
A grass collector adapted to be attached to a rear of a riding-type mower for receiving cut grass from a mower unit through a duct, the grass collector including a front container section having a rearwardly facing opening and adapted to be attached to the riding-type mower, the front container section carrying a first bottom plate having a substantially horizontal position. A rear container section is supported pivotably about a pivot point located in a rear upper region of the front container section and pivotable between a first position wherein the rear container section substantially covers the opening of the front container section and a second position pivoted from the first position to allow cut grass to fall, the rear container section having a second bottom plate having a substantially horizontal position.
