If you’re running earthmoving gear on a civil site or a residential build, you know that track failure equals immediate downtime. But one of the most common mistakes we see tradies and subbies make when ordering replacement rubber tracks is confusing Posi Track tracks with standard skid steer tracks.

While the machines might look identical from the cab, what’s going on underneath is completely different. Buying the wrong tracks won’t just burn a hole in your wallet—they simply won't fit your undercarriage.

Here is exactly why ASV tracks and standard compact track loader tracks are not interchangeable, and how to make sure you’re ordering the right gear for your machine.

What is a Posi Track?

A Posi Track is a specific type of Multi-Terrain Loader (MTL) originally developed by ASV Holdings. While the term "Posi Track" is often thrown around as a generic name for any tracked skid steer, true Posi Tracks utilise a specialised, patented rubber track undercarriage. Unlike standard machinery tracks, Posi Track tracks are non-metal core tracks made with Kevlar or heavy-duty poly cords, designed to flex over terrain and provide maximum traction with minimal ground disturbance. (Want to know more about where the design came from? Check out the [External Link: ASV Holdings History of Posi Track] for the full background).

The Difference Between CTL and MTL Tracks

To understand why the tracks won't swap over, you need to look at the two different undercarriage systems:

1. Compact Track Loaders (CTL) / Tracked Skid Steers

When most blokes talk about skid steer tracks or compact track loader tracks, they are referring to the standard CTL setup used by major brands like Caterpillar, Kubota, and Komatsu.

  • The Build: These tracks have a continuous steel cord and steel embeds (lugs) moulded directly into the rubber.
  • The Undercarriage: The steel lugs engage directly with a steel drive sprocket. The undercarriage is generally rigid, built for heavy lifting, aggressive digging, and harsh, rocky Aussie environments.

2. Multi-Terrain Loaders (MTL) / Posi Tracks

If you are driving a genuine ASV, Terex, or certain Cat MTL models, you are using the Posi Track system.

  • The Build: ASV tracks are specifically designed as non-metal core tracks. Instead of steel, they use flexible, high-tensile poly cords. The drive lugs are made entirely of rubber.
  • The Undercarriage: Instead of a steel sprocket engaging with steel lugs, Posi Tracks use a "squirrel cage" style roller sprocket that engages with the rubber lugs. The undercarriage uses a torsion axle suspension system, allowing it to mould to the ground. This gives you an incredibly smooth ride and floats over soft dirt, turf, and mud without tearing the site up.

Why They Aren't Interchangeable

It all comes down to the drive system. If you try to wrap standard steel-embedded skid steer tracks around a Posi Track undercarriage, the pitch (the distance between the drive links) won't line up with the roller sprockets. Even if you somehow forced it on, the steel embeds would immediately chew your roller sprockets to pieces.

On the flip side, putting Posi Track tracks on a rigid CTL undercarriage would result in the steel drive sprockets shredding the rubber lugs right off the track in minutes, leaving you stranded on site.

Finding the Right Fit for Your Machine

Getting the right track matters for the lifespan of your undercarriage and keeping your crew moving. If you’re working primarily on harsh rock or demolition sites, a standard CTL with steel-embedded tracks is usually the go-to. If you're doing landscaping, working on soft ground, or need high flotation and speed, the ASV Posi Track system is unmatched.
