Three New Mid-Sized Models Added
to Bobcat M-Series Compact Excavator Line

The new E42, E45 and E50 models join the Bobcat® M-Series compact excavator line in the 4 to 5 t weight class. All three feature improved performance and operator comfort.

The E42 is a Conventional Tail Swing unit with an operating weight of 4194 kg. The E45 features Zero Tail Swing and weighs 4570 kg, while the E50 is a Minimal Tail Swing model weighing 4843 kg. The E42 and E45 come with a 41,8 hp liquid-cooled diesel engine while the E50 is equipped with a 48,8 hp engine.

Redesigned hydraulics with a load-sensing pump and closed center-valve system provide improved, refined control of machine travel and work-group operation. The new hydraulics combined with re-engineered boom geometry also result in increased bucket breakout forces. Cushioned work-group cylinders offer smooth end-of-stroke for precise control.

The E42, E45 and E50 also include an auto-idle feature which, if activated by the operator, automatically returns the engine to idle if excavator functions are not used for a period of four seconds, saving fuel and reducing jobsite noise. The engine automatically returns to the preset throttle position as soon as the operator starts working again. For precise engine speed adjustments, a new easy-to-use rotary knob has been added to the controls.

Integrated slew brakes hold loads still and steady on slopes for more accurate placement. The need for the operator to manually engage the slew brakes during transport is eliminated, making it easier to load and position the machine.
In addition, Bobcat’s exclusive in-track swing frame keeps the swing castings and cylinders within the width of the tracks when digging in an offset position, helping the operator dig flush against an obstacle. When other compact excavators work in an offset dig position, their components extend outside the tracks and reduce their ability to dig in tight areas.

All of the new models are available with a long arm option that maximizes dig depth, reach and dump height clearance. Other popular options include pad-ready steel tracks, a hydraulic angle blade, second auxiliary hydraulics, hydraulic clamp and Hydraulic X-Change attachment mounting systems for quickly switching between the 16 attachments approved for use on the machines.
