Economical Discovery Series hydraulic excavators, designed to deliver “more dig for the dollar,” are now available in two-wheel-drive and four-wheel-drive models. Developed by Gradall Industries in collaboration with Freightliner, Discovery Series D 152 and D 154 models are budget-priced and designed for excavating and maintenance work frequently performed by governments and specialty contractors.

The first crossover excavator machines, Discovery excavators are equipped with the versatile telescoping, full-tilting Gradall boom that can rotate attachments 220 degrees to handle more jobs, more efficiently – even under bridges and trees where mini excavators, backhoes and tractor loader backhoes can't operate. With productive 220-degree attachment rotation and 25-foot reach, the Discovery Series machines are adept at grading, culvert replacement, landscaping, mowing, vegetation control as well as removal and replacement of curbs, gutters and sidewalks.

The D 152 with two-wheel-drive and the D 154 with four-wheel-drive meet specific travel and repositioning needs, operating on pavement, dirt, sand, mud or snow. On jobsites, the machines can be repositioned from the upperstructure operator cab, traveling at speeds up to 7 mph. Traveling to jobs or back to the equipment yard, Discovery Series excavators can be driven at highway speeds.

Discovery Series excavators are powered by a single Cummins 6.7 liter engine – emission compliant in all 50 states – with 220 gross hp and 520 ft. lbs. of torque.

With a compact, near-zero tail swing, Discovery Series excavators can easily handle ditching and grading work along two-lane roads with only minimal traffic flow interruption. For full working stability, the excavators have front axle lockout cylinders and do not require outriggers, even when working at either side or to the rear of the machine.

The advanced Bosch Rexroth designed hydraulic system has pressure-compensated, load-sensing valves with reliefs on all circuits. This system supplies the right amount of hydraulic power for the job at hand while also conserving fuel.

The roomy upperstructure operator cab features all-electric joystick controls, heating and air conditioning and an in-cab switch that lets the operator choose the Gradall, Deere or SAE joystick pattern.

The standard Freightliner M 2 chassis day cab has two fixed or air ride seats, an automotive style flat dash with easy-to-read LED backlit gauges and controls, adjustable steering column, electric powered windows, dual reading lights, radio and advanced heating and air conditioning systems.

Product support for Discovery Series models is available from the extensive networks of Gradall and Freightliner distributors.

All Gradall excavators are designed, built and supported by Gradall Industries, Inc., with processes that meet ISO 9001-2008 standards. Gradall Industries is wholly owned by the Alamo Group.
