Case M Series Crawler Dozers

October 17, 2013

Case M Series crawler dozer line includes five hydrostatic-drive models, the 750M (92 horsepower), 850M (112 horsepower), 1150M (127 horsepower), 1650M (150 horsepower), and 2050M (214 horsepower).

Key features found on M Series dozers include increased drawbar pull and horsepower ratings over predecessor models, the first SCR technology built into a dozer (850M through 2050M), fuel savings up to 14 percent according to Case, new versatile controls, and a pressurized cab. An advanced load management system 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.  

The Tier 4-Interim SCR engines on models 850M through 2050M are built by Fiat Powertrain Technologies (FPT). The 750M, designed primarily for the rental market, uses a cooled EGR engine that is also produced by FPT. This emissions treatment requires DPF maintenance but no end-user involvement in filling DEF.

New control customizations allow the operator to better tailor machine performance to job site conditions, including the ability to set blade sensitivity (1150M through 2050M), steering sensitivity and shuttle sensitivity to smooth, moderate or aggressive. This allows the operator to adjust machine responsiveness and controls to their preferences and ground conditions. A new electro-hydraulic joystick further simplifies operation by providing better feel and responsiveness to the operator, Case says. Fingertip blade shake allows for quick blade cleaning, and a grading mode reduces blade speed by 40 percent for increased accuracy. Each M Series dozer is also compatible with blade control technologies from Leica Geosystems, Topcon and Trimble to match operator preference.
