THE 3.5 Heavy Duty Rear Loader

3.5 CUBIC YARD HEAVY DUTY REAR LOADER

The McNeilus Heavy Duty 3.5 Rear Loader delivers performance and durability with a 3.5-cubic-yard hopper for added capacity and fast pack-on-the-go hydraulics to boost route efficiency. Its powerful compaction handles up to 1,000 pounds of refuse per cubic yard, while AR200 and AR450 abrasion-resistant steel reinforces high-wear areas for long-lasting performance. Optional Excalibre™ cylinders with hardened nitrided rods and a patented tool steel shaver reduce hydraulic contamination. Built for demanding routes and tight schedules, the Heavy Duty 3.5 not only performs but retains top resale value—making it a smart investment for any fleet.
