The smallest of the Caterpillar wheel tractor-scraper line, the 613, has been upgraded to G-Series performance, comfort and serviceability standards. The new model features a tractor that has been redesigned from the ground up. With increases in power train efficiency, rimpull, elevator speed and travel speed, the 613G is more productive than its predecessor and can load material as much as 13 percent faster, according to the manufacturer.
The new 613G replaces the 613C II and features a cleaner, quieter and more powerful engine; a 95-gal. (360 L) fuel tank that supports 10- to 12-hour shifts; 30 percent more cab space for greater operator comfort; plus numerous improvements to the hydraulic, braking and electrical systems.
The 613G has an 11.0-cu.-yd. (8.4 cu m) heaped capacity and is suited for smaller earthmoving, road construction and site preparation jobs where its self-loading capability, spreading ability, speed and maneuverability contribute to high productivity and versatility.
High-Efficiency Power Train
Powering the 613G is a new Cat C6.6 engine with air-to-air aftercooling. It meets U.S. EPA Tier III and European Union Stage III A emissions regulations and delivers 193 flywheel hp (144 kW), a 3 percent increase over the previous model. A new torque converter increases rimpull, improving performance and maneuverability in tough materials. The combination of higher rimpull and faster elevator speed allow the 613G to fill its bowl faster than the 613C II.
New Fuel, Hydraulic, Braking and Electrical Systems
Virtually every major system on the 613G has undergone significant change. The large fuel tank enables the machine to run long work shifts without stopping to refuel. Clean-out ports, sediment drains and strainers were added to the fuel filtering system to improve cleanliness and extend component life. Fuel filters are readily accessible to simplify service and reduce maintenance time.
The hydraulic system includes a new 33.8-gal. (128 L) tank designed for easy access and better serviceability. A new pump increases elevator speed. Hose routings have been improved and use less hardware to help ensure long, trouble-free service.
Hydraulically actuated brakes replace the air braking system found on the previous model. This change improves braking performance and serviceability. The parking brake, which also is hydraulic, is effective on grades as steep as 15 percent.
The electrical system incorporates LED lights, which offer visual clarity, reliability and long life. Light guards provide extra protection in severe applications. A flexible polyurethane-coated wiring harness withstands harsh conditions. It incorporates small, replaceable sections for faster, easier service.
The machine also features Product Link, a machine tracking and asset management tool that improves fleet utilization and reduces costs.
Roomy, Comfortable Cab
The 613G comes with a standard cab that has 30 percent more space than the previous machine’s cab, standard air conditioning, a standard Cat comfort seat and low sound levels (76 dBA). The seat swivels and locks to allow comfortable viewing of the cutting edge and bowl when loading and spreading. Ergonomic implement controls and easy-to-read instrument clusters further enhance productivity.
For precise work without relying on grade stakes, the 613G can be delivered from the factory ready to install the AccuGrade system, a grade control solution that guides the operator in determining how much and where to cut or fill. The color display inside the cab is easy to read and follow. The onboard software has the same look and feel as AccuGrade used on other Cat machines, so operators can learn the system quickly and easily.
