CASE Construction Equipment has extended its range of wheel loaders with two models featuring more powerful engines and redesigned cabs.
According to the company, the additions to the E series of wheel loaders, with the model numbers 621E and 521E, have four work modes. The operator can match power and fuel economy to suit their application, by selecting Maximum Power, Standard Power, Economy Mode or Auto Mode.

Auto Mode chooses either maximum power or standard power modes depending on engine load.
The 521E outputs 101 net kW in maximum power mode, a 23% increase over the 521D it replaces, 93 net kW in standard power mode and 76kW in economy mode.

The 621E delivers 121 net kW in maximum power mode, a 20% increase over the 621D, 109kW in standard power mode and 93kW in economy mode.

Both new models have a redesigned cab, with the cab floor area enlarged for maximum legroom and comfort. The front tyres are visible due to floor-to-ceiling glass. A sloping rear hood allows visibility for the rear.
