Description
Overview:
The Courage 15 Throttle Linkage is a genuine Kohler part designed to connect the governor to the carburettor throttle lever and deliver smooth, accurate engine speed control. Made from formed steel for strength with a durable metallic finish, this linkage restores precise response from idle through full throttle. It is suitable for a wide range of Kohler engines used on ride‐on mowers, zero‐turns, compact construction equipment and other small machines. Compatible with popular models such as KS530 and KT740, it provides an OEM‐correct fit and geometry for dependable running and long service life. OEM No. 2515811‐S ensures you are fitting the exact replacement specified by Kohler for consistent performance and easy installation.
Key Features:
- Genuine Kohler OE linkage for correct fit and operation (OEM 2515811‐S)
- Formed steel construction for rigidity and long‐term durability
- Accurate governor-to-carburettor control for stable idle and top‐end RPM
- Factory bend geometry helps prevent binding and hunting under load
- Compatible across many Kohler horizontal and vertical shaft engines
- Straightforward swap with basic hand tools; minimal downtime
- Helps resolve poor throttle response caused by worn or bent linkages
- Corrosion-resistant finish suitable for outdoor power equipment
- Designed to work with existing Kohler clips and carburettor levers
- Supports reliable performance in both garden and light construction machinery
Typical Applications:
Used on Kohler-powered ride‐on lawn tractors, zero‐turn mowers, compact utility equipment, generators, pumps and similar machinery where steady governed speed is essential. Ideal as a direct replacement during carburettor service, governor repairs or when correcting erratic RPM, surging, sluggish throttle, or inconsistent idle caused by a damaged or stretched linkage.
