Adjustable Leaf Blower Duct on Ride-On Mower Deck
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ride-on mowers lack an effective and integrated solution for blowing off fallen leaves while in operation, as they typically require manual adjustment and do not consider leaf blowing functionality.
Innovation Solution
A ride-on mower design incorporating a mower unit with a rotary blade and a leaf blower unit, where the fan drive power transmission mechanism is simplified and the air discharge opening direction can be adjusted by the operator, allowing for effective leaf blowing without protruding components that could collide with obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fan drive power transmission mechanism and shroud are arranged to not protrude outward from the mower deck, then the risk of collision with obstacles is reduced and the design remains compact, but the leaf blower functionality may be compromised
Solution Approach 1:
The duct is made adjustable rather than fixed, allowing it to be positioned at multiple angles. This enables the air discharge opening to be oriented effectively for leaf blowing while keeping the fan drive power transmission mechanism and shroud within the mower deck boundaries, preventing protrusion and collision risk
2Device complexity
If the air discharge opening direction is fixed, then the structure is simpler, but the operator cannot effectively control the leaf blower for different cleaning scenarios
Solution Approach 1:
The duct is designed with adjustability, allowing the operator to change the air discharge opening direction according to different cleaning needs. This dynamic adjustment capability provides operational flexibility without significantly complicating the overall structure
Solution Approach 2:
The duct is separated into adjustable segments or sections, allowing independent adjustment of the air discharge opening direction while keeping the rest of the leaf blower unit structurally simple and integrated
3Shape
If the leaf blower unit components are arranged compactly under the mower deck, then the overall design is more compact and safer, but the available space for component arrangement is limited
Solution Approach 1:
The fan drive power transmission mechanism and shroud are arranged within the mower deck boundaries, nesting components efficiently within the available space. The duct extends from this nested arrangement to provide the necessary air discharge function without requiring additional external space
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the operator to control the leaf blower while driving, effectively cleaning fallen leaves with reduced risk of collision and maintaining a compact design that protects the fan drive power transmission mechanism and shroud under the mower deck.
Implementation Method 1
The leaf blower unit includes a fan, a fan drive power transmission mechanism for transmitting rotational power from the blade drive power transmission mechanism to the fan

AI summary
A ride-on mower including a frame unit supported to the ground through front wheels and rear wheels, a drive unit for supplying drive power to the front wheels and/or rear wheels, a mower unit, and a leaf blower unit. The ride-on mower is also provided with a blade drive power transmission mechanism for transmitting drive power to a blade of the mower unit, and a fan drive power transmission mechanism for transmitting rotational power from the blade drive power transmission mechanism to a fan. An adjustment mechanism is provided for adjusting the direction of an air discharge opening of the leaf blower unit. The leaf blower unit is arranged on a mower deck of the mower unit.
