Case 621F, 721F Wheel Loaders Meet T4-F Standards

May 22, 2015

Models 621F and 721F wheel loaders meet Tier 4-Final emissions standards with a 6.7-liter engine using SCR technology that improves fuel efficiency up to 20 percent, according to the company. The 162-horsepower 621F and 179-horsepower 721F are available in tool carrier (XT) and extended reach (XR) versions.

Four programmable power modes allow users to match machine output to available engine power. Heavy-duty axles have auto-locking front and open rear differentials.

An optional “Efficiency Power” package has a five-speed transmission with lock-up torque converter for faster roading speed, acceleration and shorter cycle times, the company says.

Cabs have full climate control and a joystick steering option that helps reduce operator fatigue, the company says. Floor-to-ceiling windows enhance visibility. All service points are grouped and located throughout the machine for easy access.
