Understanding the Governor on Lawn Mowers
The governor on a lawn mower plays a crucial role in maintaining the engine’s speed and power. It automatically adjusts the throttle position to ensure the engine runs at optimal RPMs, preventing it from over-revving or stalling.
Purpose of the Governor
The primary purpose of the governor is to regulate engine speed. When the engine speed increases, the governor reduces the throttle opening, allowing less fuel and air into the engine. Conversely, if the engine speed drops, the governor opens the throttle to increase power. This balance ensures that your mower operates efficiently and effectively, enhancing its overall performance.
Types of Governors
Governors come in a few different types, each with its specific function.
- Mechanical Governors: These rely on centrifugal force. As engine speed increases, spinning weights move outward, closing the throttle. Mechanical governors provide consistent performance in various mowing conditions.
- Electronic Governors: These use sensors and computer systems. They adjust throttle position based on actual RPM data. Electronic governors offer precision control and adapt quickly to changes in load.
- Flyweight Governors: These are a type of mechanical governor that uses weights to control throttle position. They are commonly found in smaller engines.
Understanding the type of governor on your lawn mower is essential for effective adjustments. Each type requires different maintenance and tuning approaches.
Tools Needed for Adjustment
You’ll need specific tools and safety equipment to adjust the governor on your lawn mower. These tools help ensure a smooth and efficient process.

Locating the Governor
- Consult the Manual: Refer to your mower’s manual for specific instructions related to the governor’s location.
- Find the Engine: Open the engine compartment. The governor typically attaches near the carburetor or throttle linkage.
- Identify the Type: Recognize whether your governor is mechanical, electronic, or flyweight. Each type presents unique adjustment points.
- Start the Engine: Fire up the mower and let it run for a few minutes. This warms up the engine and gives you a clearer picture of the governor’s performance.
- Use the Tachometer: Measure the engine’s RPMs with the tachometer. Identify if the RPMs are within the manufacturer’s specified range.
- Adjust the Throttle Linkage: Loosen the locking screws on the governor arm. Adjust the throttle linkage to increase or decrease engine speed as needed.
- Tighten Everything: After making the necessary adjustments, tighten the screws securely. Ensure all connections are firm to prevent future issues.
- Recheck RPMs: After adjustments, run the mower again and check the RPMs. Confirm they meet the recommended settings to optimize performance.
