Cat 12M3, 140M3, 160M3 motor graders have been upgraded to Tier 4-Final compliance.
Cat 12M3, 140M3, 160M3 motor graders have been upgraded to Tier 4-Final compliance. The Cat C9.3 ACERT engines use SCR technology, and the necessary DEF can be filled from ground level when the machine is fueled. A standard economy mode can be used to reduce engine speed for fuel efficiency. The company cites an average fuel savings of 10 percent depending on application. Two electronic joysticks reduce arm movement by 78 percent, according to the company. A redesigned message display located in the center console of the machine monitors grade control and DEF tank levels.
The GD655-6 motor grader is a 218-horsepower unit with closed-center, load-sensing hydraulics.
The 12 models (670G/GP, 672G/GP, 770G/GP, 772G/GP, 870G/GP, 872G/GP) in John Deere’s G Series motor grader line, with net horsepower ranging from 220 to 287, now have John Deere PowerTech Tier 4-Final engines.
Extending an industry trend that targets lower-hour users with less expensive, base machines that stay under 75 horsepower to avoid DEF aftertreatment, Caterpillar has introduced the 313F L GC hydraulic excavator, a companion unit to the higher-spec'd 312E L.
The 173-horsepower Cat MH3027 material handler is the fourth and smallest in the series of wheeled material handlers that Caterpillar is introducing in the greater-than-25-metric-ton size class.
