Case Construction Equipment’s 621F and 721F wheel loaders now meet Tier 4 final emissions standards. Like the Tier 4 interim models, each model is equipped with a selective catalytic reduction (SCR) solution that treats emissions separately with diesel exhaust fluid (DEF) and does not require the engine to re-circulate exhaust gas. This improves fuel efficiency by up to 20% greater than previous solutions, lowers exhaust temperatures and fuel consumption, and provides excellent throttle response and simplified maintenance without sacrificing power, according to the company. It also requires no diesel particulate filter (DPF) regeneration or maintenance.

Each new Tier 4 final wheel loader delivers best-in-class horsepower with a 6.7L engine. The 621F and 721F wheel loaders produce 162 and 179 net rated hp, respectively.

The 621F and 721F wheel loaders have four programmable power modes that allow users to match the machine output to available engine power. The loaders include heavy-duty axles with auto-locking front and open rear differentials for optimal traction. The axle design also helps reduce tire wear, especially on hard surfaces, according to Case.

The 621F and 721F wheel loaders feature cabs with full climate control. Floor-to-ceiling windows provide excellent visibility to attachments. All service points are easily grouped and located throughout the machine for easy access.
