CASE 621E–821F: linkage, power modes and editions

Which E/F loader configuration is being offered?

A 621E listing can describe a bucket loader, extended-reach machine or tool carrier. The European E-series publication identifies the XT linkage separately from the Z-bar and XR arrangements. Its loader handle carries direction and downshift buttons; the alternative multi-lever controls place the shuttle on the console.

Try the arrangement fitted to the machine. A familiar model number does not tell an operator where those controls sit.

The E's electric hood exposes a rear-mounted engine, while the cooling module sits farther forward. For a cleaning inspection, the brochure describes a removable air-conditioning condenser and quick-release inner fender. Check that access, not just the outside grille.

Optional Ride Control has an automatic setting that engages above 4.8 km/h in this European publication. Its presence should be confirmed before expecting that loaded-travel function.

F-series transmission and attachment choices

CASE's Tier 4 Interim family brochure distinguishes the standard four-speed transmission from the optional five-speed lock-up arrangement offered for the 721F and 821F. POWERINCH belongs to the latter package. It lets the operator approach a loading target while keeping engine speed available for the loader hydraulics.

A four-speed machine should not be advertised as having that package without equipment evidence.

The same brochure offers XT parallel-lift tool-carrier arms on the 621F and 721F, with dual tilt cylinders and an integrated coupler. XR is the reach alternative across the family. Fork work therefore calls for the XT attachment and capacity schedule, not a bucket figure borrowed from an XR.

Commodity King is another specific package: the 621F/721F version adds cooling and protection for airborne debris.

Rated output versus peak output

The later 621F Tier 4 Final sheet separates net rated power from peak net power. Maximum mode gives 152 hp at 2,000 rpm and 162 hp at 1,800 rpm respectively. Neither is an all-mode rating.

That sheet also specifies a 120-amp alternator, whereas the Interim family equipment list prints 65 amps. Match the publication and installed electrical equipment before ordering an alternator.
