Rotary Mower Assembly for Post-Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mower designs fail to make a clean and neat cut completely around fence posts and other vertical posts, with few successful solutions in the market.
Innovation Solution
A mower design featuring a support structure mounted to a tractor, with a mower assembly comprising multiple rotary blade units that rotate around the post, allowing two units to engage and cut on one side while the others reposition to engage the next side, ensuring a complete cut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single mower unit is used to mow around posts, then the device complexity is reduced, but the manufacturing precision and completeness of the cut deteriorates
Solution Approach 1:
The mower assembly is divided into multiple independent mower units (at least two, preferably four) that can be selectively positioned and engaged. Each mower unit operates independently to cut grass on different sides of the post, allowing complete circumferential coverage without requiring a single complex mower mechanism.
2Manufacturing precision
If multiple mower units are used to ensure complete cut around post, then the manufacturing precision improves, but the device complexity increases
Solution Approach 1:
Each mower unit is designed with universal functionality to perform the same cutting operation on different sides of the post. The mower units are interchangeable and can be positioned at various locations (front, rear, left, right) of the support structure, allowing the same basic unit to serve multiple functions in completing the circumferential cut.
3Productivity
If the mower assembly rotates to reposition mower units, then the productivity improves by reducing repositioning time, but the device complexity increases
Solution Approach 1:
The mower assembly incorporates a rotation mechanism that allows the entire assembly to rotate about the support structure, enabling dynamic repositioning of the mower units. This dynamic capability allows the mower to efficiently transition from cutting grass on one side of a post to the next side, improving productivity when multiple posts are present without requiring manual intervention.

AI summary
A mower assembly is provided for cutting around a post. A support structure supports the mower assembly in cantilever fashion. The mower assembly includes a plurality of mower units with each mower unit having a rotary blade. Two or more mower units cooperate to engage and cut around a post and, during the process, the entire mower assembly rotates about an axis enabling the mower units to encircle and efficiently cut grass and other vegetation about the post.
