Mower Slope Portion Oblique Movement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mid-mount mower configurations face challenges in smoothly transitioning slope portions between storage and use positions due to potential contact with vehicle wheels, especially on work vehicles with short wheelbases, leading to inefficient operation and potential damage.
Innovation Solution
The mower design incorporates front and back slope portions with supporting and linking mechanisms that allow for oblique movement between storage and use positions, minimizing contact with vehicle wheels by using elongate holes and shafts, and manual operating portions for easy operation, ensuring the slope portions can be efficiently moved and positioned without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the slope portion moves horizontally between storage and use positions, then the structure is simple, but the slope portion contacts vehicle wheels causing operational inefficiency and potential damage
Solution Approach 1:
The slope portion's movement path is changed from horizontal to oblique by introducing vertical displacement through the linking portion mechanism. The slope portion moves along an oblique trajectory combining horizontal and vertical components, which elevates it above the wheel path and prevents contact while maintaining operational smoothness
2Productivity
If the wheelbase of work vehicle is short, then the mower is more compact, but the slope portion is more likely to contact wheels during movement
Solution Approach 1:
By changing the movement trajectory from horizontal to oblique with vertical component, the slope portion operates in a different spatial dimension that avoids the wheel path. This dimensional change allows compact mower design on short-wheelbase vehicles without sacrificing operational reliability
3Productivity
If the slope portion moves horizontally, then the mechanism is simpler, but operation is less smooth and efficiency is reduced
Solution Approach 1:
The oblique movement path achieved through the linking portion mechanism enables smooth operation and high working efficiency. The additional vertical dimension in movement trajectory, while adding mechanical complexity, provides the necessary clearance and smooth transition that horizontal movement cannot achieve

AI summary
There are included a passage portion provided at an upper surface portion of a mower deck, front and back slope portions and provided at front and back portions of the passage portion, front and back supporting portions supporting the slope portions in such a manner that the slope portions are movable in the front-back direction and swingable in the up-down direction, and front and back linking portions that are supported in such a manner as to be swingable in the front-back direction about axes extending in the left-right direction and that are connected with the slope portions. Operating the front and back linking portions in the front-back direction causes the front and back slope portions to be operated to the storage and use positions.
