Exclusive CASE G Series Productivity, Efficiency & Performance 

At the core of every CASE G Series wheel loader is power, fuel efficiency, and the comfortable and intuitive way the operator and the machine work together. The 621G is powered by an FPT engine with patented selective catalytic reduction (SCR) emissions technology — there’s no diesel particulate filter (DPF) and no regeneration. This creates greater fuel efficiency, keeps operating temperatures down and puts all working effort of the engine to the work. And standard Ride Control provides an extremely smooth ride with optimum material retention.

The CASE 621G offers standard four-speed operation and limited slip differentials for excellent performance in changing conditions; optional auto-locking front and conventional/open rear differentials are ideal for operation on improved surfaces and consistent loading applications with a tight cycle.

An optional five-speed PowerShift transmission with lock-up torque converter provides faster acceleration and roading speeds up to 25 mph. And Powerinch provides incredible accuracy and control in tight loading areas, regardless of engine speed or grade.

Operation Made Even Easier 

Enhancements to CASE G Series wheel loaders include adjustable electro-hydraulic controls that allow the operator to independently set boom and bucket responsiveness to smooth, moderate or aggressive — the aggressive setting with the bucket function is ideal for topping off trucks and hoppers by finely feathering/metering in material. A touchscreen display puts all core machine operating information and control within reach. Two simplified power modes — Smart and Max — let you work in the way that makes the most sense for your operation. And three color-coded, configurable buttons on the armrest make three pre-set tasks, functions or settings as easy as the push of a button - all with minimal movement or distraction for the operator.

Ensure Greater Uptime 

Anything can be connected. It’s the ability to take action based on the information that connectivity provides that improves everything from fuel efficiency to productivity and uptime. Each CASE G Series wheel loader comes connected with the SiteConnect Module to improve telematics reporting (including additional parameters) and allow for critical functionality such as remote diagnostics and software updates. This provides a greater flow of information to business owners, fleet management personnel — and fleet management partners such as your local CASE dealer and CASE technical experts at the CASE Uptime Center.*

The connectivity of the SiteConnect Module also allows for reporting and ticketing with the optional integrated payload system, and reporting and features for the optional Tire Pressure Monitoring System (TPMS).

Improve Load Accuracy and Reporting 

An optional, fully integrated payload system improves load accuracy and provides detailed real-time reporting (integrated in CASE SiteWatch telematics) for billing, tracking and operational performance. It helps prevent under- and over-loading of trucks, and ultimately results in faster cycle times with less hassle and wear and tear over time. And as it is integrated from the factory, the payload system is purpose-built for CASE G Series wheel loaders, is incorporated with the purchase/financing of the machine, and requires no installation time/aftermarket solutions. Please see more detail below.

Work in Comfort 

A spacious cab with standard heating and air conditioning and an adjustable workstation gives the operator the perfect vantage point and comfort to get more done. A sweeping single-pane windshield with extensive floor to ceiling glass, combined with an optional LED light package and optional rearview camera on the touchscreen display (operable in all directions for greater awareness), gives the operator optimal visibility and confidence.

Keep it Cool. Keep it Clean. 

The CASE-exclusive Mid-Mount Cooling Module allows all coolers to have access to cool, clean, ambient air for keeping mechanical and hydraulic systems cool. Its location also reduces the amount of dust and debris that gathers around the coolers over time. The 621G also features a standard programmable hydraulically driven reversing fan that helps prevent buildup and makes it easy to clean out debris.

Peak Groundline Serviceability 

CASE G Series wheel loaders provide easy access to the engine compartment for excellent groundline serviceability. All major regular service points, including HVAC system filters and components, can be accessed from ground level — and remote drain ports are standard.
