CASE has announced an update of its compact wheel loader line, with the launch of four F-Series Evolution models.
The 21F, 121F, 221F and 321F machines are all said to benefit from increased travel speeds and an upgraded cab incorporating a revised monitor, electro-hydraulic controls with smart features, and a range of connectivity applications previously only seen on larger models.
The two larger models are available with a choice of travel speed ratings, 20kph in standard trim and an optional 40kph for customers looking to move rapidly between sites.
CASE said that when combined with optional Ride Control arm suspension, the higher travel speeds also deliver increased productivity in load and carry operations, where machines are rapidly transferring material to a loading or stocking area.
Powered by a Stage V FPT diesel engine, the 21F boasts 43kW (58hp) and 245Nm of torque. This rises to 48kW (64hp) and 261Nm in the 121F, topping out at 55kW (74hp) and 316Nm in the 221F and the 321F. The larger models have new modular axles, available with limited slip or 100% locking differentials for ‘maximum traction’ in difficult terrain. They feature multi-disc wet brakes with a hydraulically-released parking brake.
Evolution wheel loaders have an Eco drive mode, limiting engine revs to 1,700rpm for reduced fuel consumption and lower exhaust emissions. While operators might expect a drop in productivity in Eco mode, CASE explained that engine speed regulation and variable hydraulic pump displacement results in ‘impressive’ performance. Indeed, CASE recommends operators set the machines to run in Eco in regular daily operation to achieve ‘optimum productivity and efficiency’, unless maximum power is required for attachments or increased breakout force.
There are two cab interiors on offer, both featuring ROPS and FOPS level 2 protection as standard. The Deluxe cab includes additional storage spaces around the seat, with full height adjustment for the steering wheel and an adjustable wrist rest.
The electro-hydraulic joystick controls all bucket and loader arm functions, while the automotive-style display monitor provides access to major machine functions and system controls. A membrane keypad, similar to that found in larger CASE machines, puts controls at the operator’s fingertips without leaving the wrist rest, while smart features allow operators to pre-set hydraulic response to suit individual tasks.
A bucket shake mode assists the emptying of sticky materials. As well as a return-to-dig function, there is now a return-to-travel setting and CASE added that the two automated movements can be combined for easier operation in loading and tipping. A return-to-height function is also offered.
Overall height of the 21F and 121F is just 2.46m, while the 221F is 2.63m high and the 321F sits at 2.68m overall.
The 21F weighs in at 4,570kg with a standard bucket and Z-bar linkage loader arms. This rises to 5,423kg for the 121F, then 5,694kg for the 221F and tops out at 6,195kg for the 321F.
