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 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.
The 38,510-pound G946C motor grader is now Tier 4-Final equipped, and features a heavy-duty circle, moldboard and drawbar, with a blade pull at base of 24,957 pounds.
The new all-purpose 982M, which recently was added to the Cat Medium Wheel Loader range, is similar, says Caterpillar, to the 980K 12-ton Aggregates Handler.
The Cat MH3037 is the third model in a new wheeled-material-handler range that Caterpillar is introducing in the greater-than-25-ton size class.
