The 621E is powered by a Tier III Case 667TA/EDB diesel engine. This electronically-controlled 6.7 litre engine offers the operator a choice of three power and torque ratings, from 133-172 hp (99-128 kW), each designed to match the requirements of the machine in specific applications. This boosts productivity and reduces fuel consumpt ion and exhaus t emi ss ions. In addition the machine has four Working Modes, which are selected by the operator. Standard mode is for use in normal operation, offering the engine’s standard rated output with maximum hydraulic power and flow.

Max Power provides a 13.5 % power boost and is intended for extreme operating conditions. For lighter duties, there is Economy mode, which drops the engine revs and power output by 15 % , reducing fuel consumption, exhaust and noise emissions further. The final operating mode is Auto mode, which automatically matches the engine’s power curve to the digging application. The electronic engine control also permits three idle settings, 600, 900 and 1,200 rpm, further reducing fuel consumption and exhaust emissions.

Case E Series wheeled loaders benefit from a greatly enlarged operator’s cab, with up to 15 % more floor area. The tapered design is longer and wider than the D Series, offering more internal space for the driver and reduced noise levels that are among the quietest in the industry.

Floor to ceiling glass is present at the front and sides, offering unparalleled visibility to the wheels and the implement, increasing efficiency and productivity on site. Redesigned front wheel arches offer improved protection for the cab, while increasing the operator’s view to the bucket.

At the rear of the 621E, the sloping single-piece engine canopy provides industry-leading levels of visibility. The optional engine air pre-cleaner is positioned in line with the exhaust stack at the rear of the canopy to further improve visibility. A large single rear screen, with pillars level with the operator, ensures an unbroken view to the rear three-quarters of the 621E. This is essential for a wheeled loader operator in a stocking and loading operation, and also for the XT machine in a materials handling situation.

A rear windscreen wiper is standard, ensuring that the view to the rear of the machine stays clear whatever the weather, minimising downtime and maximising productivity.
