Side-Mounted Bagger for Stand-On Mower
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stand-on mowers lack efficient grass clipping collection solutions, with existing baggers either obstructing the operator's view, increasing the machine's footprint, or requiring frequent emptying, which affects efficiency and maneuverability.
Innovation Solution
A side-mounted bagger apparatus with removable bags and a hood that allows for easy emptying and reattachment, positioned to minimize interference with the mower's operation and maintain a compact footprint, featuring a duct and impeller assembly for efficient clipping collection and a pivotal spring mechanism for easy hood operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a front-mounted bagger is used, then grass clipping collection is achieved, but the operator's view is obstructed and dust is generated
Solution Approach 1:
The bagger is extracted from the traditional front-mounted position and relocated to the rear of the mower. This separation removes the source of clipping collection from the operator's immediate workspace, eliminating view obstruction and dust generation in the operator's vicinity while maintaining effective grass clipping collection capability
Solution Approach 2:
The bagger is positioned in the rear横向 space of the mower, utilizing the transverse dimension behind the operator rather than the front longitudinal space. This spatial reconfiguration allows clipping collection without interfering with the operator's forward view and reduces dust exposure to the operator
2Quantity of substance
If a rear-mounted bagger is used, then grass clipping collection is achieved, but the machine's footprint increases and maneuverability is reduced
Solution Approach 1:
The bagger is designed to nest within or alongside the mower's existing rear structure, utilizing available space efficiently. The bagger integrates with the mower's frame and components, allowing it to occupy minimal additional footprint while maintaining adequate clipping collection capacity
Solution Approach 2:
The bagger is positioned specifically in the rear transverse area of the mower, concentrating the clipping collection function in a localized region that does not significantly increase the overall machine footprint. This localized placement preserves the mower's maneuverability while achieving effective clipping collection
3Loss of time
If a large capacity bagger is used, then frequent emptying is reduced, but the mower's maneuverability and performance are adversely affected
Solution Approach 1:
The bagger is designed with a moderate capacity that balances between reducing emptying frequency and maintaining maneuverability. The removable bag design allows for dynamic adjustment - bags can be quickly removed and replaced, enabling efficient operation without requiring excessive bagger capacity that would compromise the mower's agile handling characteristics
4Ease of operation
If a side-mounted bagger with removable bags is used, then ease of emptying is improved, but device complexity increases
Solution Approach 1:
The bagger system is segmented into a stationary housing and removable flexible bags. This segmentation allows the bags to be independently removed and emptied without disassembling the entire bagger structure, significantly improving ease of emptying while keeping the overall device complexity manageable through modular design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables efficient grass clipping collection without obstructing the operator's view, maintains a compact machine size for easy storage and transport, and reduces the need for frequent emptying, enhancing operational efficiency and maneuverability.
Implementation Method 1
The bagger apparatus or grass catcher may have: one or more bags that are removably mounted on the machine's frame for collecting grass clippings, leaves and the like; a hood that covers the bags and that is easily moveable between open and closed positions; and an impeller assembly and duct for moving clippings from the cutting deck to the bagger.

AI summary
A bagger attachment for use with a stand-on lawn mower. The bagger includes, in some embodiments, an impeller, a duct, and one or more bags which are covered by a hood. The hood is attached to a pivot frame that allows movement of the hood between open and closed positions. The bagger attachment may also include a frame assembly that facilitates mounting and removal of the bagger attachment from the mower. The bagger attachment may either contain removable bags, or may include a discharge door for dumping the clippings.
