Bobcat has introduced the company’s smallest ever skid-steer loader in the shape of the S70. Replacing the company’s earlier 463 model the new S70 measures in with a trimmed width of just 901 mm, an overall length (including standard bucket) of 2,55 m and height of 1,81 m. Thus the S70 represents Bobcat’s most compact, transportable and maneuverable loader in the company’s 50 year history.

Driven by a 16,8 kW Kubota D1005-E3B-BC-3 diesel engine, a tier four system that offers -50% lower particulate emissions, Bobcat is keen to point out that the power-to-weight ratio of the S70 sets new standards for the class. Improved productivity through faster roll back and bucket dump functions should provide +10 % more efficiency in cycle times too.

As Bobcat strives to offer ever-improved machine durability the S70 features an enhanced lift arm design offering increased strength, a new micro, serpentine-style V-belt-drive with automatic tensioner, more robust components, a vibration reducing engine mount and a simpler design that uses technology from the company’s larger loaders. Additionally, the S70 features a new hydrostatic pump control centering system which benefits from a tension spring rather than the more traditional torsion spring. This improved spring system should reduce maintenance and increase uptime.

The transverse mounted engine and swing open tailgate offer ease of maintenance and easy access to standard service points. All routine maintenance components such as the oil dipstick and fuel filters are conveniently located just inside the tailgate. The tip-up operator cab - which in normal operation features both falling object protection and rollover protection - provides complete access to hydraulic and hydrostatic components for servicing.

Inside the cab, the operator has a seat belt and a seat bar that doubles as both a secondary restraint and a convenient armrest. Additional safety features include Bobcat’s patented Interlock Control System, which prevents operation of the machine’s lift and tilt hydraulic functions and the traction drive system if the operator is not in the seat with the seat bar down and the engine running. Another safety feature in the form of an ‘auxiliary interlock valve’ blocks hydraulic flow to the auxiliary lines if the seat bar is not down.

With a hydraulic flow of 33,7 l/min at 91% efficiency, the new S70 offers excellent versatility through the ability to work with an extensive range of Bobcat attachments. The quick-change Bob-Tach frame ensures that over 20 Bobcat attachments can be fitted securely and safely in seconds.
