Bobcat M-Series Excavator Design Improves Performance, Comfort, Maintenance

Construction Equipment Guide

Bobcat’s M-Series excavators are re-engineered to deliver increased performance in a lighter machine. Throughout each model are enhancements that save time and labor and make operators more comfortable, according to the manufacturer.

The new E32 and E35 M-Series excavators are in the 3-to-4-ton (2.7 to 3.6 t) weight class. These two machines follow the introduction of the new M-Series E80, which is in the larger 6-to-8-ton (5.4 to 7.2 t) weight class.

Ultimate Digging Performance

Bobcat 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 metering for smooth control of machine functions. With the new advanced hydraulic system, Bobcat was able to increase the arm breakout force by 10 percent over previous models.

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

Bobcat designed the M-Series excavators to use X-frame undercarriages. This new undercarriage has increased ground clearance and enables 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 on the E32 and E35 boost the machines’ productivity. Auto-shift travel shifts the machine out of high range and back automatically, which provides 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. Included with Bobcat’s angle blade is the bolt-on replaceable cutting edge that is easy to rotate and simple to replace, providing lower operating costs, according to the manufacturer.

Quieter Operation and All-Day Comfort

The E32 and E35 also include an auto-idle feature. The auto-idle feature, which can be enabled at the operator’s discretion, automatically causes the engine to return to idle if the excavator’s functions are not used for a period of four seconds. The machine automatically returns to the preset throttle position after the operator starts working again. When work is paused, fuel is saved and sound levels are reduced.

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 percent. New directional lug tracks also offer a smoother ride.

Operator Comfort

A significant contributor to excavator productivity is the comfort of the operator. Bobcat has designed the cab so the operator is comfortable in the machine, whether spending one hour or a whole day at the controls. 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. The 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 rotary knob.

The new E32 and E35 excavators also feature an integrated slew brake. The brake eliminates the need to manually engage a slew brake when transporting the machine, and provides infinite brake positioning.

Options and Specifications

Popular excavator 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 also are lockable to prevent vandalism.

The E32 and E35 have 33.3 hp (24.6 kW) engines, dig depths of 10 ft. 2 in. (3.1 m) and a dump height of 11 ft. 3 in. (3.4 m).

The E32 has a reach at ground level of 16 ft. (4.8 m), and the E35 has a ground-level reach of 16 ft. 9 in. (5.1 m).
