The all-new Mustang zero-tail-swing excavators consist of five models — the 170Z, 270Z, 350Z, 450Z and 800Z (pictured). Designed around a Yanmar interim Tier 4 engine, the machines are true zero-tail-swing machines, with no cab overhang beyond the tracks in any direction.

The Mustang 270Z, 350Z, 450Z and 800Z excavators are equipped with a hydraulic quick coupler, making attachment changes as simple as flipping a switch, the maker said. Plus, the pin-grabber style hydraulic coupler works with the majority of excavator attachments, putting tools already in the fleet to use.

“Mustang zero-tail-swing compact excavators meet the reach, dig depth and lift capacity requirements of builders, landscapers, general contractors, plumbers and excavation crews nationwide,” said Nathan Ryan, product manager for Mustang compact excavators. “Consumers are looking for more zero-tail-swing models in the 1.7 to 8.0 metric ton capacity range than ever before. This new compact excavator product offering from Mustang addresses the demand we have recognized in the mini-excavator market.”

The hydraulic system on the new excavators incorporates two variable pumps and two gear pumps. The pump oil flows are combined and redirected where needed allowing for simultaneous operation without loss of hydraulic power. An operator can save fuel when full performance is not necessary by reducing engine rpm by 10 percent using the Eco mode on the 800Z. The mode is easily activated and deactivated with a toggle switch.

Mustang’s zero-tail-swing excavators are equipped with rugged, high-strength booms constructed with a single boom-pin design and thick side-plates with internally routed lines. Heavy-duty cylinder guards protect exposed cylinders from damage. Longer, offset crawler tracks enhance stability and provide smoother travel. Tracks are short-pitched to reduce wear, fatigue and damage. The angled crawler frame reduces soil buildup on the undercarriage.
