The D7E is especially popular in Waste applications because of its productivity, maneuverability and demonstrated fuel efficiency. The Electric Drive system, powered by a Cat C9.3 ACERT engine, is designed to deliver quantum leaps in improved productivity and fuel efficiency. The D7E is more productive* – moving 10 percent more material per hour. Up to 30 percent better fuel economy, plus greater productivity, means you can move up to 35 percent more material per gallon/liter of fuel.

A quiet, spacious cab with center-post design gives you outstanding visibility all around the machine. Operators can also enjoy added comforts like manually adjustable armrests and a heated/ventilated seat option. Cab-mounted heating, ventilation and air conditioning (HVAC) system provides efficient cooling.
Ergonomic controls are fully adjustable and designed for low-effort. Speed Recall allows operators to pre-set the desired forward and reverse travel speed, and then resume that speed simply by pressing a button. Implement Lock-Out prevents inadvertent operation of hydraulic attachments.

Waste Handling Guarding and Seals
Cat Waste Handlers are designed and equipped from the factory to handle the unique challenges of landfill work.
Heavy duty hinged radiator guard helps protect fan and radiator. Designed to resist material penetration from straight-in and under the blade. Tight mesh helps prevent material entry during reversing fan purge cycle.
Optional Waste Handling Attachments
Rugged, three-part cooling system features a highly efficient aluminum bar plate radiator. Single-plane design allows easier cleaning and wide fin spacing helps reduce plugging. In cooler conditions, the hydraulic demand fan reduces speed to conserve power, save fuel and decrease sound levels. Automatic reversing fan efficiently removes debris from the cooling cores without the operator leaving the cab.
D7E waste handlers are offered in two track shoe widths. The 660 mm (26 inch) shoe has greater compacting and shredding characteristics and higher ground pressure. The 914 mm (36 inch) shoe provides greater flotation in soft underfoot conditions. Trapezoidal hole shoes are recommended for trash applications. The shoe is specially designed to shed waste that can otherwise contribute to accelerated internal track wear.
A wide, straight landfill blade easily handles heavy or bank materials. It features a ½ inch wear plate on the moldboard and an integrated 610 mm (24 in) trash rack. With the rack, this blade has a capacity of 12.3 m3 (16.1 yd3). Ask your Cat dealer about other blade options.
Multi-shank rippers with integrated striker bars can make short work of loosening and preparing cover material. Cast-in ripper mounts allow a ripper to be mounted quickly and easily.
The D7E meets U.S. EPA Tier 4 Final/EU Stage IV/Korea Tier 4 emission standards. Emissions reduction technology on the D7E is designed to be transparent, with no action required from the operator. Regeneration runs automatically in the background while you work. Selective Catalytic Reduction utilizes Diesel Exhaust Fluid (DEF), which can be conveniently refilled when you refuel. A gauge on the dash shows your fluid level. When the machine is turned off, a pump will automatically purge the DEF lines to help prevent freezing. A symbol on the dash and a light/symbol on the Ground Level Service Center indicate when the purge is complete and that it is safe to turn off the electrical disconnect. If the engine/aftertreatment temperatures are high, a Delayed Engine Shutdown will activate automatically to cool the machine and then purge the lines. For complete aftertreatment information, please refer to your machine’s Operation and Maintenance Manual.
