Mack LR (Low-Cab-Forward Refuse)
Low cab forward, refuse-specific • Production 2015–present
About the Mack LR (Low-Cab-Forward Refuse)
The Mack LR is a purpose-built low-cab-forward refuse truck. Distinct from the TerraPro (which has a low-entry conventional cab), the LR is a true cab-over-engine design optimized purely for refuse. Available with right-hand drive (for curbside operations), left-hand drive, or dual-drive configurations. The LR was the first Class 8 truck to use a stand-alone battery electric powertrain — the Mack LR Electric — which is in commercial service with various US municipalities.

Design and engineering

Generations and major changes
Market position and popularity
LR is a leading refuse chassis in North America. Major refuse operators (Waste Management, Republic Services, Waste Connections, Casella) use LR fleets. The LR Electric is one of the first commercially-deployed Class 8 electric trucks in commercial service.
Who buys this truck
