Equipped with an electronically regulated engine that increases economy while maintaining reliability, the Case 621E Loader. The new common-rail fuel-injection system in the 6.7-liter Tier III-certified engine. The engine is electronic and enables air and fuel to mix in almost equal amounts for a cleaner burn. To achieve this, it is built into the engine’s fully electronic, Tier III-certified design.

Performance and Fuel Economy

With three power curves – maximum, standard, and economic power – as well as four work modes – maximum, standard, and economy – operators may tailor power and fuel efficiency to their specific application. Suppose the operator is engaged in high operations such as aggregate procedures that need high breakout force and rapid cycling. In that case, the operator may elect to operate at maximum capacity at all times.

When transporting lighter goods, the economy mode ensure that the job is completed with the least amount of fuel consumption possible. The electronically controlled engine automatically varies between power curves in auto mode to move the most amount of material per gallon of fuel possible. The Case 621E six-cylinder engine has a net horsepower output of 168 horsepower. To decrease fuel consumption, the model has many idle settings. When the machine is idling, it will automatically lower the engine rpm from 900 at maximum to 600 at low idle, depending on the engine speed.

Design, Comfort, and Quality

The 621E Loader comes equipped with limited-slip rear axles. This automatically transfers force from the wheel that is sliding to the holding wheel. This resulted in improved traction and efficiency on the road. Because of the large amount of floor-to-ceiling glass in the front and the sloping rear engine compartment, the operator has a panoramic view and excellent sight both ahead and to the back. The newly designed counterweight is contoured to the back of the machine. Therefore, the loader offers both more mass and better space for the rear of the machine.

When working on operations involving several attachments, the Case hydraulic coupler will be of great assistance to the operator in question. Those engaged in road and bridge construction will discover that transitioning from buckets for material handling to brooms for cleaning is simple and straightforward. On sewage and water projects, switching from forks to haul pipe to a boom to place a manhole and back to a bucket for backfilling would increase production. Attachment adjustments perform quickly and simply from the operator’s seat.

The coupler is suitable with Case rapid-fill buckets, which have a five-degree angle to the floor plate to allow for smoother movement of material from one end of the bucket to the other, resulting in enhanced productivity.

Commodity King Package

The Commodity King option package best serves two severe operating conditions: concrete-paved agricultural and industrial enterprises, such as feedlots, dairies, and batch factories, as well as pasture-based cattle and dairy farms. The Commodity King package contains unique cooler modifications designed to guard against large-particle pollutants that are frequent in these settings. Open differential rear axles help decrease tire wear on paved roads, while bigger and more specialized buckets help increase production.

When used in agricultural and select industrial applications, the Commodity King package helps to keep fluid system coolers operating at peak efficiency. This is achieved by offering more protection from excessive particle matter. This is performed by closing the coolers to ensure that air goes through a screen that filters out contamination. The space between cooler fins has been increased to allow materials that pass past the grill screens to travel through the coolers.
