Riding Mower Linkage Mounting with Segmented Pillars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing riding-type mowers face difficulties in mounting the linkage mechanism on uneven ground surfaces due to the need for simultaneous coupling of upper and lower links, which requires significant force and is cumbersome, especially when the ground is not flat.
Innovation Solution
The design allows individual coupling of upper and lower links to pillars, with a posture maintaining mechanism to ensure proper alignment and a lightweight, simple structure for the mounting brackets, including swingable components and stoppers to maintain the desired posture, and tension rods to facilitate easy mounting and dismounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If both upper link and lower link are coupled simultaneously to the coupling body, then the end parts of upper link and lower link can move synchronously, but the mounting operation becomes difficult and requires large force
Solution Approach 1:
The coupling body is divided into two separate coupling bodies - one for the upper link and one for the lower link. This segmentation allows each link to be coupled independently to its respective coupling body, eliminating the need for simultaneous coupling and reducing the force required during mounting operations while maintaining synchronous movement through the linkage mechanism
2Adaptability or versatility
If the linkage mechanism is placed on uneven ground surface, then the coupling bodies mounting locations tend to be deviated, but adjustment becomes burdensome requiring large force
Solution Approach 1:
The coupling bodies are designed with adjustable mounting positions and orientations on the support frames. This dynamic adjustment capability allows the coupling bodies to be repositioned to compensate for deviations caused by uneven ground surfaces, enabling proper alignment without requiring excessive force or complex adjustment procedures

AI summary
A riding-type mower is provided, in which upper links and lower links of linkage mechanisms can be coupled with less operator's force to a pair of pillars fixed to a body side. The riding-type mower includes a cockpit (20) having an operator's seat (21) and formed on a body frame (1) supported against the ground surface by front wheels (2a) and rear wheels (2b), a pair of left and right pillars (3) fixed to the body frame (1) and extending above the operator's seat (21), the pillars (3) being separated from each other in body lateral direction, a linkage mechanism (4) having a pair of left and right upper links (4A) and lower links (4B), the links being detachably and separately mounted to the corresponding pillars (3), and a grass container (5) held by the linkage mechanism (4).
