Mustang Excavators — 2016 Spec Guide

The Original Workhorse Markets Six Zero Tail Swing Units

Mustang excavators were first introduced in 1999. Thirteen years of industry knowledge and market experience has produced the third generation of Mustang excavators — the Mustang zero tail swing excavators. The evolution of the Mustang excavator line over the years has led to more user-friendly features and zero tail swing designs for operation in tight places.

The Mustang zero tail swing excavators consist of six models: the 170Z NXT2, 250Z, 350Z NXT2, 450Z NXT2, 550Z and 800Z NXT2. The machines are designed around a powerful and reliable Yanmar engine to enhance engine performance and increase efficiency. Mustang excavators are true zero tail swing machines, with no cab overhang beyond the tracks in any direction. This allows the machine to operate directly against a wall or other obstruction without causing damage to the structure or machine. The Mustang 250Z, 350Z NXT2, 450Z NXT2, 550Z and 800Z NXT2 excavators are equipped with a hydraulic quick-coupler. This feature makes attachment changes as simple as flipping a switch. Plus, the pin grabber-style hydraulic coupler works with the majority of excavator attachments, putting tools you already own to use.

The hydraulic systems on the Mustang zero tail swing excavators incorporate 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 350Z NXT2, 450Z NXT2, 550Z and 800Z NXT2. The mode is easily activated and deactivated with a simple toggle switch.

An angle blade with float and bolt-on cutting edge is a factory installed option on the 350Z NXT2, 450Z NXT2 and 550Z. Using the rocker switch on the blade lever, the hydraulic angle blade can be angled up to 25 degrees to push material aside as the machine moves forward.

In addition to the above features, the 170Z NXT2 is equipped with a unique variable undercarriage which extends from 3 ft, 1 in. wide to 4 ft, 2 in. wide. This allows the machine to access narrow, hard-to-reach areas and also gives it the ability to increase stability on uneven terrain.

Advice to Buyers

“The versatility of an excavator model needs to be considered during a purchase. Ensuring that you are selecting a model that will perform in all jobsite applications is key,” explains Nathan Ryan, Mustang excavator product manager. “Select a unit that has the dig depth, lifting capacity over the front and over the side and breakout force performance for your key applications.”
