Mack Trucks expanded its vocational offering to medium-duty customers with an optional Allison 3000 RDS Series transmission – a key addition for those who need to haul more payload or use a live-power PTO, including 4×2 refuse, tank and dump applications.

The live-power PTO, for example, will allow trucks to move while using the PTO at the same time.

When equipped with the Allison 3000 RDS, the truck sees a gross vehicle weight rating of 33,000 lb. And with up to a 50% increase in available gross combination weight ratings reaching 45,000 lb., an MD Series dump truck is able to pull utility trailers loaded with small excavators.

The transmission adds to the previously available Allison 2500 RDS.

Mack only recently re-entered the medium-duty market, and the first MD Series units rolled off the Virginia assembly line as recently as September 2020 after delays relating to Covid-19, but the OEM has produced 5,000 of the trucks overall. Last year, it ramped up from just 50 trucks in January to a 9% market share in December – ending the year with a 3.7% market share overall.
