Mower Deck Dual Wedge System for Vine Material Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mower deck devices face issues with vine-like materials wrapping around spindle shafts, causing interference and binding, which can lead to operational inefficiencies and damage.
Innovation Solution
A dual wedge configuration is integrated into the mower deck, with wedges positioned on either side of the spindle shaft to funnel vine-like materials away from the shaft, preventing wrapping and allowing a cutting disc to shear the materials into manageable lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional mower deck design is used, then the structure is simple, but vine-like materials wrap around the spindle shaft causing binding and operational interference
Solution Approach 1:
The patent introduces dual wedge-shaped guides as intermediary components positioned between the cutting disc and the mower deck housing. These wedges act as mediators that redirect vine-like materials away from the spindle shaft, preventing wrapping and binding while maintaining a relatively simple overall mower deck structure.
Solution Approach 2:
The solution segments the material flow control function by introducing separate wedge-shaped guides on either side of the spindle shaft. Each wedge independently manages material direction, creating segmented zones that collectively prevent material from reaching the spindle shaft, thereby improving reliability without requiring a complete redesign of the mower deck.
2Productivity
If vine-like materials are cut without guidance, then the cutting process is straightforward, but the materials wrap around the spindle shaft causing operational inefficiencies
Solution Approach 1:
The wedge-shaped guides serve as intermediary structures that channel vine-like materials along controlled paths away from the spindle shaft. This intermediary guidance system maintains straightforward cutting operation while preventing material wrapping, thereby preserving productivity without excessive complexity.
Solution Approach 2:
The patent applies local quality by positioning wedge-shaped guides only in specific areas where material wrapping is most likely to occur (near the spindle shaft), rather than implementing a comprehensive guidance system throughout the entire mower deck. This localized approach maintains cutting efficiency while minimizing added complexity.

AI summary
A mower deck dual wedge system uses a dual wedge configuration to funnel vine like material for cutting to prevent interference with a spindle shaft. The system includes a mower deck having an upper wall and a peripheral. A spindle shaft extends through the upper wall. Each of a pair of wedges is coupled to and extends from the upper wall of the mower deck. Each of the wedges has a pair of lateral sides extending from a tip. The wedges are positioned on opposite sides of the spindle shaft such that the tip of each the wedge faces away from the spindle shaft. A cutting disc is coupled to the spindle shaft and the wedges are positioned between the cutting disc and the upper wall of the mower deck. The cutting disc is rotated by the spindle shaft.
