Post installation is one of those jobs that looks simple until you’re halfway through it.
Ground conditions change. Access is tight. Posts drift out of line. And suddenly a “quick job” turns into rework, extra labour, or compromised results.
The Autoguide Postmaster was designed to remove those problems by doing one thing exceptionally well: installing posts accurately, safely, and efficiently.
Developed by Autoguide Equipment, the Postmaster range is a hydraulic post knocker - purpose-built for driving posts into the ground without digging holes, removing spoil, or relying on concrete to compensate for poor placement.
What Is the Autoguide Postmaster?
The Autoguide Postmaster is a hydraulic post knocker attachment designed purely for post installation.
It delivers controlled, repeatable post installation using hydraulic power from the carrier machine.
The Postmaster range includes:
Mini Postmaster – for smaller posts and lighter carrier machines
Midi Postmaster – a versatile mid-range option for common fencing and utility work
Maxi Postmaster – for larger posts, poles, and heavier-duty applications
Each model is matched to both post size and equipment requirements, ensuring safe and efficient operation on site.
Why Purpose-Built Matters
Many post installation methods rely on adapted attachments or handheld impact tools that were never designed for accuracy or repeatability.
Because the Postmaster is a dedicated hydraulic post knocker, it offers:
Greater control during installation
Improved vertical alignment
Consistent results across long runs of posts
Reduced need for correction or rework
Posts are installed cleanly and confidently - not forced into position and fixed later.
Designed for Real-World Site Conditions
Post installation rarely happens in perfect ground.
The Postmaster performs reliably across:
Clay, chalk, and mixed ground
Slopes and uneven terrain
Tight boundaries and restricted access sites
Agricultural, commercial, and infrastructure projects
By driving posts directly into the ground, surrounding soil remains compact and supportive, helping posts stay exactly where they’re installed.
Mini, Midi, and Maxi: The Right Tool for the Job
Selecting the correct Postmaster model is essential for both performance and safety.
Mini Postmaster
Ideal for:
Smaller posts
Lightweight fencing
Restricted access locations
Compact excavators and smaller carriers
Midi Postmaster
Well suited to:
General fencing work
Mid range excavators
Agricultural and commercial boundaries
Maxi Postmaster
Designed for:
Larger posts and poles
Heavy-duty applications
Larger carrier machines
Projects where stability and power are critical
This tiered range allows contractors to match the hydraulic post knocker to the task, rather than over-specifying equipment or compromising results.
Bespoke Jaws for Specialist Applications
One of the standout features of the Postmaster range is its adaptability.
In addition to standard post jaws suited to both round and square posts, bespoke jaws can be manufactured for specialist or non-standard applications, including:
Sheet metal installation
Unusual post profiles
Temporary works
Custom structural elements
This flexibility allows the Postmaster to be used across multiple sectors, often replacing several single-purpose tools on site.
Safer, Cleaner, and More Efficient Installation
Using a hydraulic post knocker instead of digging or manual impact methods helps:
Reduce manual handling
Minimise ground disturbance
Speed up installation
Deliver cleaner sites with less reinstatement
Operators benefit from improved visibility, controlled installation, and reduced fatigue over long runs of posts.
Where the Autoguide Postmaster Is Commonly Used
The Postmaster is widely used for:
Fencing and boundary installations
Agricultural infrastructure
Solar and renewable energy sites
Temporary and relocatable structures
Anywhere posts need to be installed quickly, accurately, and with minimal disruption, the Postmaster proves its value.
Frequently Asked Questions
Is the Postmaster a torque or foundation tool?
No. The Postmaster is a hydraulic post knocker, designed purely for post installation. It does not measure torque or perform foundation testing.
Can it install different types of posts?
Yes. With the correct model and jaw configuration, it can install timber, steel, and specialist post types.
Are bespoke jaws available?
Yes. Custom jaws can be manufactured for specialist applications, including sheet metal installation.
Does it reduce the need for concrete?
In many cases, yes. Driving posts directly into the ground maintains soil integrity and often removes the need for concrete altogether.
What makes a purpose-built post driver better than general-purpose equipment?
Purpose-built post drivers are specifically engineered to install posts accurately, consistently and with minimal ground disturbance, rather than adapting equipment designed for other tasks. This dedicated design helps improve alignment, reduce unnecessary handling and deliver more predictable results across a range of ground conditions. Operators also benefit from faster installation times because fewer adjustments are needed during the job. Choosing equipment designed for the application can reduce rework and improve overall site efficiency. Matching the attachment to the task often produces better long-term results than relying on general-purpose alternatives.
Can a hydraulic post driver be used for different types of post installation?
Yes, hydraulic post drivers can be used for a wide variety of applications, including agricultural fencing, highway barriers, utility work and commercial security fencing, provided the attachment is compatible with the post size and carrier machine. Many models can accommodate different post profiles without compromising installation accuracy. The suitability of the attachment should always be assessed alongside the ground conditions and the material being installed. Some systems can also be adapted with specialist jaws or accessories for more specific applications. This flexibility allows contractors to use the same attachment across multiple projects while maintaining consistent performance.
How can you achieve straighter and more consistent post installation?
Consistent post installation starts with stable machine positioning, selecting the correct attachment and ensuring the post is properly aligned before driving begins. Changes in soil conditions can affect how a post enters the ground, so operators should monitor alignment throughout the installation rather than relying solely on the initial position. Regular inspection of hydraulic components and attachment wear also helps maintain consistent performance over time. Working at a controlled pace often produces more accurate results than trying to complete installations as quickly as possible. Good preparation and correct operating techniques are just as important as the equipment itself for achieving reliable, professional results.
Final Thoughts: Built for the Job It’s Meant to Do
The Autoguide Postmaster doesn’t try to be everything - and that’s exactly why it works.
As a purpose-built hydraulic post knocker, it gives contractors a reliable, professional way to install posts across a wide range of sites and sectors.
Cleaner installs. Straighter posts. Less rework.
Sometimes the best equipment on site is the one designed to do one job properly - every time.
