Case adds 650L to crawler dozer line.

Case Construction Equipment has added the 650L to its crawler dozer line. The 650L delivers 74 net horsepower through a Tier 3-certified, four-cylinder, 4.5-liter turbocharged Case Family IV engine with electronic fuel injection for maximum fuel efficiency and easier starts in cold weather. A high-pressure common-rail injection system delivers excellent combustion. A charge air cooler reduces emissions and provides a cleaner and more efficient fuel burn.

The lower operating height allows the 650L to work around low overhangs, while its lighter weight is ideal for work in soft soil conditions. The shorter track means easier turning, making the machine extremely maneuverable on the job site. The compact size also makes the crawler dozer easy to transport from job to job.

For operation between buildings with narrow lot lines, Case also offers a 90-inch blade for more precise work.

The adjustable operator settings allow the customer to set the steering, shuttle and maximum speed based on personal preference or application. The Case system has dual hydrostatic pumps that deliver power to each track through large drive components. This allows operators to push more material through the turn, reducing the number of passes required to move material.

The seat on the 650L tilts easily for access to the hydrostatic system. The new design reduces the machine's operating height by five inches. Optional hydraulic test ports are now available on the 650L for fast diagnosis and easy troubleshooting.

Options

The optional cab on the crawler dozer is isolation mounted from the main frame to cushion against noise and vibration, increasing comfort and productivity. The mechanical suspension seat is standard, with an optional air suspension seat. A high-capacity air conditioning system is standard with cab units. The narrow dash and tapered hood allow exceptional visibility to the blade, making it easy to gauge material flow under the blade.

The low-effort, single-lever PAT blade control increases productivity with simultaneous, multifunction control. The operator can pitch the blade to match the material being worked.

The undercarriage features a double-reduction with planetary final drive for high tractive effort and long life. There are two track options available for the 650L crawler dozer. The Case Lubricated Track (CLT) is sealed and lubricated, with an oil reservoir in each pin. The Case Extended Life Track (CELT) uses a large diameter hardened bushing, which provides outstanding durability and undercarriage life in abrasive soil conditions.

The rigid undercarriage allows for precise track alignment and easy grading. The 650L is available in Long Track (LT), Wide Track (WT), and Low Ground Pressure (LGP) configurations to match operating condition. A 49-degree sloping track frame cover, along with ample space between the track and the machine, helps shed material and makes undercarriage cleaning easy.

Swing-out access doors and sight gauges for ground line maintenance and fluid level checks mean the operator will be spending less time servicing the machine and more time getting the job done. The front grill also swings out, along with an access door to the engine for easy servicing. Swing-up access doors reduce the time it takes to change the hydraulics and hydrostatic transmission filters.

Operating weights on the 650L are 16,250 pounds on the LT, 16,800 pounds on the WT and 17,550 pounds on the LGP. 866.542.2736, www.casece.com
