Case Construction Equipment’s F-Series line of compact wheel loaders — the 21F, 121F, 221F and 321F — are completely redesigned to provide improved maneuverability, versatility and performance. The new F Series compact wheel loaders feature Case’s “maintenance-free” Tier IV Final particulate matter catalyst solution, and offer a more compact design while simultaneously increasing breakout force and lift capacity compared to previous models, according to the manufacturer.

The new 21F is rated at 58 hp, the 121F is rated at 64 hp, while the 221F and 321F are both rated at 74 hp.

Ideal for work in general construction, landscaping and supply yards, compact wheel loaders pick up where skid steers leave off in lift capacity, ground clearance, cab height/visibility and application versatility. The new 21F, 121F, 221F and 321F models feature increased attachment compatibility, new electronic controls and added cab comfort features to improve machine performance and reduce operator fatigue. The two smaller units, the 21F and 121F, are available in two separate loader arm designs — a z-bar model for greater breakout force when using buckets and similar attachments, and a parallel lift arm for improved stability and balance when using forks and other lifting attachments for loading and transportation.

Compact Design Improves Maneuverability, Transport

With a 4- to 6-in. (10 to 15 cm) shorter wheelbase, depending on the model, the new F-Series compact wheel loaders provide a smaller turn-radius for greater job site maneuverability. The new models also feature a lower cab height — up to 13 in. (33 cm) — which, combined with the smaller foot print, makes these new models easier to load and transport.

Maintenance-Free Tier IV Final Solution

Meeting Tier IV Final standards, the new compact wheel loaders employ a particulate matter catalyst solution in conjunction with the machines cooled exhaust gas recirculation (CEGR) engine. This solution is made up of a diesel oxidation catalyst (DOC) and a high-efficiency flow-through filter, and does not require filter replacement. The DOC converts emissions into neutral gasses. The remaining particulate matter then passes through to the high-efficiency flow-through filter where it is stored and burned off.

Improved Controls Provide Simplified Operation

All new F-series compact wheel loaders feature new electronic controls that provide increased precision and reduced operator fatigue compared to mechanical controls, according to the manufacturer. Using simple rocker switches and control dials, operators can increase engine speed and operating parameters without affecting travel speed. This allows for improved performance and productivity with attachments, such as cold planers or brooms, which require low travel speed and high RPM’s. All four machines also feature Case’s automatic ride control feature, a function previously reserved for larger equipment, which engages at elevated speeds to reduce spillage and machine looping.

Attachment Versatility = Application Versatility

Offering either standard auxiliary hydraulics or a high-flow option, the 221F and 321F models provide the option for increased power for auxiliary attachments that require greater flow, such as grinders and planers. Further, a new horizontal pin coupler gives users the ability to use a greater range of attachments, including those made by other manufacturers.
