Two new machines join the Bobcat family of M-Series loaders – the S750 skid-steer loader and A770 all-wheel steer loader.
The S750 joins the Bobcat M-Series loader line, delivering 11 feet of vertical lift and features a 23-gallons-per-minute standard hydraulic flow. The skid-steer loader has an operating weight of 8,730 pounds, a rated operating capacity of 3,200 pounds and is powered by an 85-horsepower turbo-diesel engine.
Bobcat’s A770 offers both all-wheel steer and skid-steer drive options by simply pressing a switch and boasts a vertical lift path and 3,325 pounds rated operating capacity and a 6,650-pound tipping load. The design provides superior lift height (132 inches), reach (31.5 inches), and dump angle (42 degrees) for easy truck loading.
The A770 that replaces the A300 model meets the needs of users who require the low ground disturbance, reduced tire wear and faster travel speed of a small wheel loader, but also the maneuverability and versatility of a skid-steer.
It comes standard with two-speed transmission and a travel speed of 12.3 mph in high range and 7.1 mph in low range. The A770 is equipped with a 92-horsepower, liquid-cooled Tier 3 diesel engine and has an operating weight of 9,460 pounds.
The A770 has a turning circle diameter of 12.6 feet in AWS mode and 7.2 feet in skid-steer mode.
Both M-Series machines boast new features that were added to the optional deluxe instrumentation panel. The panel monitors key loader functions, and the keyless start helps prevent theft. The new 5-inch, full-color LCD screen offers better readability and interaction. Easy-to-read virtual sweep gauges allow the operator to quickly read and understand the machine’s performance.
The auxiliary hydraulic quick couplers are mounted directly to the front plate of the lift arm to provide a solid mounting, and hoses are routed through the loader arms for better protection. A guard bar extends in front of the coupler for added protection.
Keeping the loaders cool when working long hours is important in prolonging the service life of the machine. That is why Bobcat redesigned the cooling system on the M-Series for increased efficiency and higher performance. The new design also makes it easier to clean out the cooling system, with an oil cooler that swings up, allowing the operator to clean the area between the oil cooler and the radiator.
A unique cab-forward design on both models moves the operator closer to the attachment and provides unmatched visibility in all directions. Visibility is provided to the cutting edge of the bucket or the corners of an attachment because the cab door is the largest available on the market. The cab door threshold has been lowered and the overall surface of the door has increased more than 40 percent to provide improved visibility and make it easier for operators to enter and exit the cab. Windows on the sides and rear of the cab are larger to provide more visibility to the tires and to the rear. The larger top window makes it easier and more comfortable for the operator to see the attachment with the lift arms raised, an advantage when loading trucks or performing other tasks.
Bobcat M-Series loaders have a new one-piece seal that goes all the way around the door and fits into a special curved pocket. This minimizes the amount of dirt and dust that might enter the cab, creating more enjoyable working conditions and making it easier to clean the cab.
Noise is another factor affecting operator comfort, and Bobcat reduced the sound level of M-Series loaders by more than 60 percent. New engine mounts improve isolation to decrease vibration and reduce sound levels. www.bobcat.com
