Mustang excavators were first introduced in 1999. Fifteen 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. Longer-lasting components, paired with performance based designs, make Mustang excavators a popular choice in rental, landscape and construction fleets.
The Mustang zero tail swing excavators consist of five models: the 170Z, 270Z, 350Z NXT2, 450Z NXT2 and 800Z. The machines are designed around Yanmar engines 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 270Z, 350Z NXT2, 450Z and 800Z 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, says Mustang. 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 and 800Z. The mode is easily activated and deactivated with a simple toggle switch.
Mustang zero tail swing excavators are equipped with 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, says Mustang. Tracks are short-pitched to reduce wear, fatigue and damage. The angled crawler frame reduces soil buildup on the undercarriage.
The large, walk-through operator’s stations on canopy equipped models increase operator safety and comfort. An integrated boom light on all models illuminates the area being excavated, extending the work day when necessary. Easy-to-remove side covers and a large rear access door allow access to all daily inspection and major maintenance points.
In addition to the above features, the 170Z 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. The extension blade easily expands to the same width for further stability. As a complement to the Mustang line of excavators, a full line of EDGE attachments are available, including buckets, hammers, thumbs and more.
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 of the 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.”
