AJAX AF 7XE vs Schwing Stetter AM 4: Which Transit Mixer Fits Your Site?
The AJAX AF 7XE and the Schwing Stetter AM 4 both carry ready-mixed concrete to site, but they turn the drum in different ways. The AF 7XE has its own separate engine just to drive the drum, so mixing stays steady even when the truck slows down in traffic. It also carries more concrete per trip than the AM 4. The AM 4 is the smaller, lighter machine of the two, built for smaller sites and easier parking.
If you supply bigger sites and want a mixer that keeps mixing evenly in stop-start traffic, the AF 7XE is worth the extra care its second engine needs. If your sites are smaller and you want a simple, light mixer that is easy to own and run, the AM 4 fits that need well.

Questions buyers ask about the Schwing Stetter AM 4 vs AJAX AF 7XE

Ans.
The Schwing Stetter AM 4 suits a small, first-time buyer better. It is lighter, simpler, and has one engine to look after instead of two, which keeps ownership easier.
