Bobcat introduces M-Series compact excavators

Part of Bobcat's M-Series, the new E32 is a conventional tail swing excavator that has been re-engineered to reduce the overhang by 45% from previous excavators of comparable size.

Bobcat's new E32 and E35 M-Series excavators are in the 3- to 4-t (3.3- to 4.4-ton) weight class and follow the introduction of the new M-Series E80, which is in the larger 6- to 8-t (6.6- to 8.8-ton) weight class. With the M-Series introduction, Bobcat is instituting a new numbering system for excavators. The new machine numbers now correspond to the excavator’s weight in metric tons. For example, the “32” in E32 is for 3.2 t (3.5 ton).

Bobcat says it has completely re-engineered the design of M-Series excavators, reducing the weight to create a lighter machine. A new load-sensing piston pump and closed center-valve system deliver improved metering for smooth control of machine functions. With the new advanced hydraulic system, Bobcat was able to increase the arm breakout force by 10% over previous models.

The E32 is a conventional tail swing excavator and was re-engineered to reduce the overhang by 45% from previous excavators of comparable size. The E35 is a zero tail swing excavator more suitable for working on space-constrained job sites, such as next to buildings or other obstacles.

M-Series excavators use X-frame undercarriages for increased ground clearance and better shedding of debris for easier cleanup when work is finished. Dirt and other debris easily pass through this undercarriage, making cleanup faster and leaving less debris on the trailers.

The new Auto-Shift travel feature on the E32 and E35 shifts the machine out of high range and back automatically, providing an on-demand power boost when pushing into a pile. Operators get more tractive effort without having to manually control the throttle or drive.

Backfill work goes faster with an accurate, productive angle blade. The E35 features an optional angle blade that provides simultaneous up/down and angle adjustment. Exclusive to Bobcat’s angle blade is the bolt-on replaceable cutting edge that is easy to rotate and simple to replace, providing lower operating costs.

Both the E32 and E35 include an Auto-Idle feature that can be enabled at the operator’s discretion. It automatically causes the engine to return to idle if the excavator’s functions are not used for a period of 4 s. The machine automatically returns to the preset throttle position after the operator starts working again.

The new engine, air intake, cooling, and exhaust systems, along with an entirely new pump and valve system, lower sound levels, resulting in a more comfortable, quieter machine. The overall sound levels have been reduced by more than 50%. New directional lug tracks also offer a smoother ride.

A significant contributor to excavator productivity is the comfort of the operator. On the new E32 and E35, the boom swing control has been removed from the floor and placed on a thumb switch on the left joystick, which is easier to operate and opens up space on the floor for the operator’s feet. New larger travel pedals also fold up for more floor space.

New adjustable armrests allow the operator to move the rests to a more comfortable position. For precise engine speed adjustments, Bobcat added a new easy-to-use rotary knob.

An integrated slew brake eliminates the need to manually engage a slew brake when transporting the machine and provides infinite brake positioning.

Options previously offered on Bobcat excavators are still available on M-Series models, including long arm, enclosed cab, climate control, auxiliary hydraulics, angle blade, and Hydraulic X-Change mounting systems for quickly switching between the 16 attachments approved for use on the machines.

A lockable toolbox and pocket console keep tools and paperwork close at hand and secure, while rear and side access doors and fuel fills are also lockable to prevent vandalism.

The E32 and E35 have 33.3-hp (25-kW) Kubota engines, dig depths of 10.17 ft (3 m), and a dump height of 11.25 ft (3.4 m). The E32 has a reach at ground level of 16 ft (4.9 m), while the E35's is 16.75 ft (5.1 m).
