Case M Series Dozers
Case Construction Equipment said its new M Series of crawler dozers went through more than 12,500 hours of machine testing by dozens of customers before they were released into the market.
The new M Series, which will be shown at ConExpo, includes the 92 hp 750M, 112 hp 850M, 127 hp 1150M, 150 hp 1650M and the 214 hp 2050M models. The dozers were designed from the ground up and take into account extensive customer research, testing and feedback related to durability, productivity, controls, comfort and serviceability, said John Bauer, brand marketing manager for Case Construction Equipment.
He said dozens of customers tested the machines during development and their insights were used to help improve the designs. Those real-world tests were on top of the “tens of thousands of hours” in design development and testing, White said.
Enhancements to the line of dozers include improved drawbar pull, which go from 42,913 lb. for the 750M and 850M, 48,000 lb. for the 1150M, 61,200 lb. for the 1650M and 80,979 lb. for the 2050M and what Case said was the first implementation of selective catalytic reduction (SCR) technology built into a dozer.
The engines on models 850M through 2050M are manufactured by Fiat Powertrain Technologies (FPT) and incorporate SCR technology to meet Tier 4 interim standards. SCR technology was chosen because it offers advantages in terms of maintenance since there is no regeneration or diesel particulate filter to maintain. It also offers fuel efficiency improvements, said Brad Stemper, solutions marketing manager for Case.
The 850M incorporates the 4.5 L F4HFE413P diesel FPT engine. The 1150M and uses the 6.7 L F4HFE613F diesel FPT engine. The 1650M incorporates the 6.7 L F4HE6132 diesel FPT engine and the 2050M—Case’s largest dozer—uses the 6.7 L F4HFE613W diesel FPT engine.
The 750M is designed primarily for the rental market and is powered by FPT’s 3.4 L F5HFL413J diesel engine, which uses cooled exhaust gas recirculation (EGR) to meet Tier 4 interim standards. This emissions treatment requires diesel particulate filter maintenance but no end-user involvement in filling diesel exhaust fluid (DEF).
