Fuel efficiency is the focus of Case’s 621F wheel loader, which boasts a 10% increase in fuel economy from the E Series. Four power modes adjust the Tier IV engine to provide just the right amount of power for any job. A dual-mode shutdown function and fuel-saver mode further improve efficiency by setting the desired shutdown time in five-minute increments and limiting idle time, respectively. Precision maneuvering in tight spaces is possible via the Case PowerInch system. Attachments include F Series buckets with Case SmartFit bucket teeth and bolt-on edges.
