Turfgrass Brushing Assembly with Pivot Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Turfgrass mower cutting units are inefficient due to debris and the diagonal or horizontal orientation of grass blades, which can prevent cutting as the mower passes over bent grass.
Innovation Solution
A turfgrass brushing assembly that includes a frame assembly with pivot couplings and a brush holder, allowing for adjustable positioning and angle adjustment to stand grass blades vertically before cutting, ensuring effective cutting by the mower.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed brushing assembly is used, then the structure is simple, but the adaptability to different grass orientations and cutting heights is poor
Solution Approach 1:
The brushing assembly incorporates pivot couplings that allow the brush holder to rotate and adjust its angle dynamically. This enables the brush to adapt to different grass orientations (diagonal, horizontal, vertical) while maintaining a relatively simple overall structure. The dynamic adjustment capability resolves the contradiction by providing versatility without requiring multiple fixed configurations.
Solution Approach 2:
The assembly is divided into separable components: a frame assembly, a brush holder assembly, and pivot couplings. This segmentation allows independent adjustment of each component, particularly the brush holder angle, providing adaptability to various cutting conditions while keeping the base structure simple and modular.
2Ease of operation
If the brush holder assembly is fixed in position, then the device complexity is reduced, but the ability to adjust cutting height and brush angle is limited
Solution Approach 1:
The brush holder assembly is designed with rotational freedom through pivot couplings, allowing easy angular adjustment without complex mechanisms. The operator can simply rotate the brush holder to the desired angle, and the pivot coupling maintains the new position, providing ease of operation without adding significant structural complexity.
3Adaptability or versatility
If the brushing assembly is permanently coupled to the mower, then the structural stability is high, but the flexibility to adjust brush configuration is reduced
Solution Approach 1:
The brushing assembly is designed as a modular system with distinct components (frame, brush holder, pivot couplings) that are coupled through standardized interfaces. This segmentation provides both stability during operation and flexibility for adjustment, as the modular connections maintain structural integrity while allowing reconfiguration when needed.

AI summary
A turfgrass brushing assembly and system is disclosed. A frame assembly may be configured to removably couple to a mower cutting unit, and may have a cross member and two opposing side plates. Each side plate may include an array of holes and a pivot coupling configured to pivotally couple the turfgrass brushing assembly to the mower cutting unit. Each side plate may be releasably coupled to a different end of the cross member through at least one hole of the array of holes. A brush holder assembly may be adjustably coupled to the frame assembly, and may have a brush block coupling configured to couple to a brush. An angle adjustment assembly may be coupled to the brush holder assembly and the cross member. The angle adjustment assembly may pivot to adjust a relative angle of the brush holder assembly with respect to the frame assembly.
