Stand-on Mower Winged Deck Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stand-on mowers are limited by a single deck configuration, restricting cutting width and weight distribution, which affects their performance and maneuverability.
Innovation Solution
A stand-on mower design featuring a main deck with rotational blades positioned forward of the rear wheel axis and one or more deck wings, with a majority of the weight supported by rear wheels, allowing for enhanced cutting width and improved weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a single deck configuration is used, then the mower structure is simple, but the cutting width is limited
Solution Approach 1:
The deck is segmented into a main deck and one or more deck wings that can be independently configured. The deck wings are detachably coupled to the main deck, allowing the cutting width to be extended by adding wings while maintaining a relatively simple base structure. This segmentation enables the cutting width to be increased without proportionally increasing overall system complexity.
2Area of moving object
If the deck size is increased, then the cutting width is improved, but the weight distribution is adversely affected
Solution Approach 1:
The deck system is divided into a main deck and detachable deck wings. This segmentation allows the weight of the extended cutting components to be distributed in a controlled manner, with the wings being coupled at specific locations that consider weight balance and operational stability.
Solution Approach 2:
The deck wings are designed to be detachably coupled, allowing the configuration to be dynamically adjusted. Operators can add or remove deck wings based on cutting width requirements, and the system adapts its weight distribution accordingly. This dynamic configurability allows optimization of weight distribution for different operational scenarios.
3Area of moving object
If deck wings are added, then the cutting width is increased, but the maneuverability is reduced
Solution Approach 1:
The detachable deck wing configuration enables dynamic adjustment of the mower's operational characteristics. When narrow spaces require maneuverability, deck wings can be removed or folded. When wide cutting is needed and space permits, wings are attached to maximize cutting width. This dynamic adaptability resolves the contradiction between cutting width and maneuverability.

AI summary
A stand-on mower may have a deck with at least one deck wing. The mower may include a stand-on operator platform, a rear wheel axis positioned forward of the stand-on operator platform, a main deck having main deck blades with rotational axes positioned forward of the rear wheel axis, one or more deck wings, and front wheels positioned forward of the rotational axes of the main deck blades.
