The 650M is replacing the 650L in Case Construction Equipment’s dozer lineup.
The 74-horsepower dozer has been updated with all of the hallmarks of the Case M-Series dozers, including a Tier 4 Final FPT engine with Diesel Oxidation Catalyst (DOC) technology. The new 650M also features an enhanced undercarriage with improved track frame, idler, sprockets, rollers and extended-life SALT HD tracks, as well as a reinforced mainframe.
The CASE 650M dozer delivers power and productivity through increased drawbar pull (17,729 kg) and horsepower rating compared to the previous model, while also reaching Tier 4 Final compliance. It also features a hydrostatic drive system, and an advanced load management system that automatically reduces track speed (increasing torque) with a heavier load on the blade, and increases track speed (reducing torque) with a lighter load on the blade, ensuring that the machine is working at optimal power and efficiency.
The 650M utilizes DOC technology while maximizing engine horse power and torque without the need for adding complication, weight or regeneration of other systems with the proven FPT powertrain. There is no DPF regeneration or associated lifetime service costs. This helps maximize uptime and performance – all with minimal maintenance.
New M-Series Control customizations on the 650M dozer allow the operator to set both steering and shuttle sensitivity to smooth, moderate or aggressive. This allows the operator to adjust machine responsiveness and controls to their preferences as well as to match ground conditions.
The 650M features a cab-forward design with standard ROPS canopy. An optional ROPS cab with floor-to-ceiling straight-panel glass doors provides industry-leading visibility down to the blade. A sloped hood and the positioning of the operator provide excellent visibility to the ground in front of the machine. The optional sealed and pressurized cab available on all M-Series dozers helps keep dust and other materials out of the operating environment.
Vibration has been reduced compared to previous generations with a retuning of both the undercarriage and the cab mounts. Noise is reduced over previous generations, down to 73 dBa, helping to reduce operator fatigue. The new undercarriage not only reduces sound and vibration found in the cab, it also features a smaller front idler, which increases visibility to the bottom of the blade for fine-grading applications. Additional features such as a factory-installed radio and environmental controls further improve operator comfort.
For harsh operating conditions, design considerations include a redesigned undercarriage with robust components, a box-style C-frame built for heavy earthmoving, and an updated cooling package that is tested under heavy load conditions and designed to optimize engine and hydraulic temperatures. The 650M cooling system was specially tuned and upgraded to deal with the hash high heat applications often associated with operating dozers in the 650M size class. Additional components, including the cylinders, electrical system and the rippers have been engineered to last in the toughest conditions.
All daily service checkpoints – including hydraulic components, filters and electrical components – are accessible from the ground and do not require hand tools for access.
