Weighing in at 9,500 and 10,920 pounds, respectively, when equipped with an enclosed cab, the new Mustang 608 and 708 articulated wheel loaders feature two-speed hydrostatic transmissions with an inching pedal, and both use a Tier 4-certified engine—a 64.4-horsepower Yanmar with a diesel particulate filter in the 608 and a 74.3-horsepower Deutz with a diesel oxidation catalyst in the 708. Standard features for the new models include digital instrumentation, Power-A-Tach attachment-mounting system, multi-function joystick, and front and rear locking differentials activated from the joystick. A heavy-duty, oscillating articulation joint provides 45-degree turning angles left and right, complemented by 10 degrees of oscillation in both directions. This design, says Mustang, promotes optimal traction and maneuverability, and since the bucket and front tires follow a constant turning radius, the rear tires follow the path of the front tires. Narrow machine widths (66 and 84 inches, respectively, with the standard general-purpose bucket) allow the new loaders access into tight, confined spaces, which, says Mustang, most skid steer loaders with comparable operating capacities cannot access.
The “Z” bar-type bucket linkage allows for mechanical self-leveling action in both the raise and lower functions, says the company, providing generous bucket-dump angles in the mid and upper range of the lift path, as well as mechanical return-to-dig and extended forward-reach dimensions. Lift height under the bucket hinge is 130.5 inches for the 608 and 136.8 inches for the 708. Static straight tipping loads when equipped with bucket and cab are 6,743 and 7,907 pounds, respectively.
A proportional auxiliary-hydraulic system is standard equipment for both models, activated via a roller switch on the joystick and having a rated flow of 18.4 gpm at pressures to 2,900 psi. An available high-flow system increases flow to 25.6 gpm. According to Mustang, “detent and pressure-relief functions are included to optimize attachment hookup and performance,” and two easily accessible auxiliary-hydraulic lines with flat-face couplers allow powering a variety of tools. In addition, the new models are available with three auxiliary-circuit options to the front and rear.
The multifunction joystick controls the boom, bucket, float detent, travel direction, differential lock, speed selection, and auxiliary hydraulic functions. For precise attachment control, says Mustang, an inching pedal allows operators to vary ground speed, while the engine maintains a fixed speed for optimum hydraulic flow.
An open canopy ROPS is standard for the 608 and 708, and a complete cab-enclosure option is available, says Mustang, for enhanced comfort and safety. Among available optional features are a “hands-free” capable radio, air suspension seat, LED work lights, rotating beacon, rear hydraulic hookup, Hydraglide ride-control system, and three-speed transmission with speeds to 19 mph.
