Impact wrenches are powerful hand-held tools that use a hammering action to apply high levels of torque to bolts and other fasteners. They are commonly used in automotive, construction, and home maintenance tasks such as changing lawn mower blades.
Using the proper size impact wrench for the job is essential, as using a wrench that is too small can result in stripped bolts or damage to the lawn mower, while a wrench that is too large may be cumbersome and difficult to control. So here we discuss the correct size impact wrench for lawn mower blades. Let’s get started-
Understanding impact wrench sizes
Impact wrenches come in a range of sizes, with the most common being 1/2 inch, 3/8 inch, and 1/4 inch. These sizes refer to the square drive size, which is the part of the wrench that holds the socket. The size of the impact wrench is related to its torque output, with larger wrenches generally able to apply more torque.
Selecting an impact wrench with the appropriate amount of torque for the task at hand is crucial. If the wrench does not have enough torque, it may not be able to loosen or tighten the fastener properly. On the other hand, if the wrench has too much torque, it may cause the fastener to strip or the lawn mower to be damaged.

Determining the Right Size Impact Wrench for Your Lawn Mower Blade
When selecting an impact wrench for changing your lawn mower blade, you must consider a few different factors-
- To determine the correct size impact wrench for your lawn mower blade, you will need to measure the size of the blade and the bolts that hold it in place. The size of the bolts is usually indicated by the bolt’s diameter, which can be measured using a tape measure or a bolt gauge.
- Once you know the size of the bolts, you can determine the necessary torque for removing them by consulting the manufacturer’s recommendations or using a torque chart. These charts list the recommended torque values for various sizes and types of bolts. It is essential to follow the recommended torque values to ensure that the bolts are tightened or loosened correctly and that the lawn mower is not damaged.
- Another crucial factor is the power source. Impact wrenches are available in corded and cordless models. Corded impact wrenches are generally more powerful but require a nearby outlet, while cordless impact wrenches offer more mobility but have less power.
- Another factor to consider is the overall size and weight of the impact wrench. A larger and heavier wrench may be more challenging to control and cause fatigue if used for an extended period. On the other hand, a smaller and lighter wrench may not have enough power for the task.
It is always wise to try out a few different sizes of impact wrenches to determine which one feels most comfortable and effective for the task.
Size recommendations for different lawn mower blades
Here are some size recommendations for different types of lawnmowers:
- Small lawn mowers (16″, 17″, 18″): 1/2 inch impact wrench
- Medium lawn mowers (19″, 20″, 21″, 22″ ): 3/4 inch impact wrench
- Large lawn mowers (23″, 24″, 25″, 26″ ): 1-inch impact wrench
Remember that these are general lists, and the size of the bolt on your specific lawn mower may differ. It’s essential to measure the diameter of the bolt to ensure you get the correct size impact wrench.
Tips for using an impact wrench on a lawn mower blade
When using an impact wrench to change a lawn mower blade, it’s essential to follow some safety precautions to protect yourself and the tool.
- Wear protective eyewear to protect your eyes from debris.
- Always wear safety gloves to protect your hands from the impact wrench and sharp edges on the blade.
- Ensure the lawn mower is turned off and the spark plug wire is removed to stop the mower from unexpectedly starting while working on it.
- To attach the impact wrench to the bolt on the lawn mower blade, align the socket on the impact wrench with the bolt and press down firmly until it is securely in place.
- It’s always vital to make sure the socket is fully seated on the bolt to prevent slippage, which could lead to injury.
- If the bolt on the lawn mower blade is stuck and won’t loosen, you can try a few things. First, try penetrating oil to loosen the rust and help the bolt turn more easily. You can also try using a breaker bar, which is a long bar with a socket on one end that can provide additional leverage to loosen the bolt. If these methods don’t work, you can use a stronger impact wrench or seek the assistance of a professional.
