The most common concrete mixer, used on construction sites by practically all masons for laying work, is a relatively small machine, but it's not exactly light. Positioning it might not be a problem for a strong person, but the ground needs to be flat and fairly even; on slopes or uneven terrain, getting the mixer in the right spot is far from easy.

In this article, we'll see how to modify a cement mixer to equip it with a suitable ball hitch attachment, even though, lacking certification, you can't take it on public roads. This modification still makes it extremely convenient to move the mixer around the job site, placing it where it's most useful and reducing trips with heavy wheelbarrows.

Modifying the Concrete Mixer for Easy Movement
Where the hitch attachment inevitably must go, there's the drum release pedal with its rod, plus a sheet metal guard that protects everything. To apply the tow hitch attachment in that same spot, a modification was necessary: temporarily removing the sheet metal guard to drill a through-hole in the mixer's foot, where a connecting tube can be inserted to secure the hitch.
The Modifications as a Whole
The ball hitch attachment is purchased online: you can find certified, new ones for just over 20 euros. The drawbar with the attachment is inserted and secured with a bolt and nut to a tube welded to the mixer's foot. To better handle potholes and uneven ground, a side intervention to the mixer's towing implementation is replacing the small stock wheels with those from a scrapped compact car. This also required installing the car's wheel hubs.

Step-by-Step Modification Guide
- Source the hitch: Purchase a certified ball hitch attachment (60mm is common) and a compatible drawbar.
- Prepare the mixer: Remove the sheet metal guard protecting the drum release mechanism. Locate the foot of the mixer where you'll mount the hitch.
- Drill and install: Drill a through-hole in the mixer's foot. Insert a sturdy connecting tube and weld or bolt it securely. Attach the drawbar and hitch with a bolt and nut.
- Upgrade the wheels (optional but recommended): Replace the small original wheels with larger ones from a compact car. This requires adapting the car's wheel hubs to the mixer's axle.
- Test movement: Attach the mixer to a vehicle or outdoor patio furniture dolly (if permitted) and test maneuvering on your property.
Where Can It Be Used?

Frequently Asked Questions
Can I use this modified mixer on public roads?
No. Without official certification (homologation), it's not legal to tow this mixer on public roads. It's designed for private property and job sites only.
What size hitch do I need?
A standard 60mm ball hitch (like the Unitec 10335) is commonly used. Ensure your vehicle's tow bar matches. For towing equipment, consider BBQ grills & outdoor cooking supplies trailers if you need road-legal options.
Do I have to upgrade the wheels?
No, but it's highly recommended for rough terrain. Larger wheels from a compact car improve stability and ease of movement over bumps and holes.
What tools do I need for this modification?
You'll need a drill with metal bits, wrenches, a welder (for the tube), and basic home improvement tools. Safety gear like gloves and goggles is essential.
