Updated: Nov 15, 2023

When it comes to erecting fences, installing signposts, or building structures in the great outdoors, post knockers play a vital role. Often referred to as post drivers, these tools are essential for securing posts firmly into the ground, ensuring stability and longevity. In this article, we will explore the functionality, types, and best practices of post knockers, equipping you with the knowledge to master this essential skill.

Understanding Post Knockers (Post Drivers)

Post knockers, commonly known as post drivers, are specialized tools designed to drive wooden, metal, or plastic posts into the ground. Their primary purpose is to achieve a sturdy and durable foundation for various structures, including agricultural fences, road signs, gardens, and more. These tools provide a more efficient and reliable alternative to traditional manual methods, saving time and physical effort.

Types of Post Drivers

a. Manual Post Knockers: Manual post drivers are basic and commonly used tools in construction and agricultural settings. They are operated by hand and rely on human force to drive the post into the ground. While these are suitable for occasional use, they may be labour-intensive for large-scale projects. b. Pneumatic Post Drivers: Pneumatic post drivers utilise compressed air to drive posts into the ground. These drivers are more powerful than manual ones, making them ideal for handling heavy-duty tasks. They are commonly used in commercial construction and fencing projects. c. Hydraulic Post Drivers: Hydraulic post drivers are the heavyweights of the post knocking world. They are powered by hydraulic systems, often mounted on machinery such as tractors or excavators. These drivers can handle large posts and are the go-to choice for professional contractors.

Key Features of Post Knockers

a. Impact Energy: The impact energy determines how forcefully the driver hits the post. Higher impact energy ensures efficient and swift post installation. b. Weight: The weight of the post driver affects its ease of use and portability. Lighter models are more convenient for smaller projects, while heavier ones are better suited for more significant tasks. c. Vibration Reduction: Advanced post knockers come with vibration reduction features, reducing operator fatigue and minimizing stress on the equipment.

Tips for Using Post Knockers Effectively

a. Safety First: Always wear appropriate safety gear, including gloves, goggles, and ear protection, when operating a post driver. b. Choose the Right Driver: Select the post driver based on the type and size of posts you will be working with. Consider the terrain and the scale of the project. c. Prepare the Site: Clear the area o


f any obstacles and ensure the ground is level and free from rocks and debris. d. Technique: Use a consistent and controlled driving technique to ensure the post goes in straight and level. Avoid striking the post off-center. e. Maintenance: Regularly inspect and maintain your post driver to ensure its longevity and optimal performance.


Mastering the art of post knockers, or post drivers, is a valuable skill for anyone involved in outdoor construction and fencing projects. Understanding the different types of post drivers, their key features, and best practices for using them will not only improve efficiency but also ensure the stability and durability of your structures.
