Mack Trucks introduced at the World of Concrete the new Mack mDRIVE rolling start and auto neutral features for trucks equipped with Mack’s mDRIVE and mDRIVE HD automated manual transmissions.
“Mack’s mDRIVE transmissions serve a wide range of customers, including paving and concrete applications,” said Tim Wrinkle, Mack construction product manager. “Now updated with rolling start and auto neutral, mDRIVE transmissions are even better suited to those tasks.”
The Mack mDRIVE rolling start feature allows drivers to shift the transmission into drive without engaging the truck’s service brakes, eliminating the possibility of creating a bump in the paving surface, a critical benefit for paving applications.
The new auto neutral feature allows the driver to automatically shift the mDrive transmission into neutral while the parking brake is set. This helps improve jobsite safety by reducing the possibility of the truck moving while remote throttle controls are in use. Both new features are standard on all Mack mDRIVE and mDRIVE HD transmissions.
Mack's mDRIVE and mDRIVE HD automated manual transmissions are engineered to work exclusively with Mack’s MP series engines.
The mDRIVE HD 13-speed configuration offers a low reduction gear ratio designed for easier starting on steep grades or when the truck is under heavy load. The 14-speed configuration (available only in an overdrive configuration) adds a second ultra-low-speed reduction gear designed for curb pouring applications or low-speed, heavy-haul maneuvering. Both transmissions offer up to four reverse gear ratios..
Mack mDRIVE is standard in Pinnacle models and mDRIVE HD is standard in Granite models.
