Since entering the excavator market in 1987, Mustang has focused on providing the right mix of compact excavators for the market. The brand-new addition to Mustang’s compact excavator line, the 550Z, enhances its North American excavator offering with its 5.5 metric ton size. This new model provides excellent performance while lowering fuel consumption and operating costs.
The new 550Z is equipped with a 47.6 hp (35.5 kW) Yanmar Tier 4 certified, turbocharged diesel engine which features an electronic throttle for precise control. Cost savings are made possible with the ECO mode and auto deceleration features. When activated by the flip of a switch inside the cab, ECO mode will reduce the engine speed by 10 percent without sacrificing power, while auto deceleration decreases the engine speed to idle after four seconds without hydraulic movement. These two features provide a combined result of 20 percent reduction in fuel consumption.
The operator’s station has many features to enhance productivity and controllability. The controls on the 550Z include a proportional auxiliary hydraulic rocker switch which enhances attachment options. This allows the operator to adjust the hydraulic flow for optimal attachment performance. The operator can easily select standard ISO or an optional backhoe control pattern with a turn of a mechanical lever. A boom offset swing of 68 degrees in both directions allows for digging a square hole without repositioning the machine. An integrated digital display located in a highly-visible area features recordable maintenance history with adjustable time intervals and reminders. The display unit also records hours used for the past 90 days and can be monitored without starting the engine.
An angle blade with float and bolt-on cutting edge is a factory installed option. Using the rocker switch on the blade lever, the hydraulic angle blade can be angled 25 degrees to push material aside as the machine moves forward, eliminating the need for repetitive repositioning. The blade can be simultaneously angled and raised or lowered to reduce the amount of time backfilling.
The operator’s station offers multiple ergonomic and convenience features. A four-way adjustable seat offers custom height, weight and backrest positions with a retractable belt. An optional cab enclosure, with heat or heat/air-conditioning systems, provides comfort and protection in extreme weather conditions. The front window can be stowed overhead for additional airflow when weather permits, and also increases visibility and communication with bystanders when needed. Tool-free component access is made possible by large swing-out doors on the back and right-hand side of the machine. These compartments reveal the entire engine and daily maintenance points; radiator, oil cooler, battery and fuses. Remove the cab floor panels, kick plates and tip the seat back to reveal the starter, alternator, fuses, control module and control valve. A left-side front panel reveals the control pattern selector and the left-side rear panel is a handy lockable toolbox for operator necessities.
The Mustang 550Z zero-tail-swing compact excavator is positioned in the North American market to meet the needs of construction, utilities, telecommunication, landscaping and rental industries. Mustang zero-tail-swing compact excavators excel in applications such as grading and excavating, trenching, digging, demolition and recycling, cabling and light utility construction. Their compact nature and zero-tail-swing design make them ideal in situations where space is limited.
“The new 550Z zero-tail-swing excavator from Mustang provides operators with additional dig depth and power without sacrificing economical fuel consumption,” says Nathan Ryan, product manager for Mustang Compact Excavators. “Its electronically controlled Tier 4 emissions-certified Yanmar engine has fuel-conserving features that result in up to 20 percent fuel savings. The 550Z comes standard with the features our customers enjoy on the rest of the lineup, including proportional auxiliary hydraulic controls, digital display, Power-A-Tach and control pattern selection valve. Optional features include a time-saving angle dozer blade and a factory-installed hydraulic thumb, which is an extremely useful feature for landscaping and demolition.”
