Outfitted with the Cummins L9 engine, the MHD now features a lower option of 330 horsepower and up to 1,000 lb.-ft. of torque paired with the Allison 3500 transmission. That’s down from a standard 350 horsepower and 1,150 lb.-ft. of torque.
A new under-frame exhaust offers more options for body adaptation, potentially unlocking new applications like tankers, flatbeds, box trucks, cranes and certain municipal applications.
“It’s totally up under the frame and the rails are totally clean,” says Tim Wrinkle, Mack’s construction product manager.
The MHD model can be spec’d as a Class 7 or Class 8 vehicle, is offered in either an axle back or axle forward configuration, and is available as a 4×2 or 6×4. An axle back tractor option meets the needs of light tractor applications requiring maneuverability, flexibility and durability without extra weight.
A shorter wheelbase is also available for the MHD model in the 4Ă—2 configuration, ideal for 10-foot dump bodies commonly found in municipal applications.
Mack also announced Wednesday it is adding ground clearance for underbody scrapers to its Granite model, making it more appealing for snow removal.
