CASE 521G Wheel Loader Overview
The CASE 521G is part of CASE’s G Series lineup of wheel loaders, built to deliver strong performance and efficient operation across a wide range of job site demands. Positioned as a mid-size wheel loader, the 521G offers a step up from smaller models like the CASE 321F — giving contractors greater power, higher lift capacities, and more versatility while still maintaining fuel efficiency and compact maneuverability.
This loader is designed with flexibility in mind. The 521G is available in three different linkage configurations:
- Z-Bar for general-purpose material handling and digging
- XT (Tool Carrier) for enhanced parallel lift and pallet handling
- XR (Extended Reach) for higher dump heights and loading trucks or hoppers more easily
Under the hood, the 521G is powered by a 4.5L FPT engine, delivering up to 142 horsepower, with intelligent power management that boosts fuel economy without sacrificing performance. It’s also equipped with advanced cooling features and a compact design that allows it to tackle urban, industrial, and heavy-duty rural environments with confidence.
The CASE 521G sits comfortably in the sweet spot for operators who want more than a compact loader can offer, but still want the nimbleness and fuel savings of a machine smaller than full-production loaders. It’s ideal for snow removal, construction prep, municipal work, and material handling — making it a true workhorse in any fleet.
Performance and Power Specs of the CASE 521G
The CASE 521G doesn’t just deliver on paper — its real-world performance speaks volumes. Designed for power, precision, and productivity, this wheel loader offers an impressive balance of strength and fuel efficiency, helping operators get more done with less waste.
Powerful Engine with Tier 4 Final Compliance
At its core, the 521G is powered by an FPT 4.5L engine, producing up to 142 gross horsepower. It uses a Selective Catalytic Reduction (SCR)-only emissions solution, which means it doesn’t require a diesel particulate filter (DPF), reducing maintenance downtime and operating costs. The engine design optimizes combustion for performance while minimizing environmental impact — perfect for companies with sustainability goals or looking to reduce fuel expenses.
Best-in-Class Visibility and Comfort
CASE built the 521G with the operator in mind. The cab offers 360-degree visibility, which is critical for safety and efficiency — particularly in tight urban jobsites or busy yards. The optional rear-view camera and tall, wide windows help operators stay aware of their surroundings with ease.
The control layout is intuitive, allowing for fingertip precision when operating lift arms or switching attachments. With an adjustable seat, climate control, and low noise levels, the cab makes long workdays more productive and less fatiguing.
Variable Hydraulic Settings
The 521G features three customizable power modes and four programmable lift and tilt settings, giving operators full control over how the machine performs depending on the task. Whether you’re doing fine grading, material handling, or heavy-duty loading, the machine adapts to your needs without compromise.
Smooth Ride and Stability
Thanks to its ride control system and heavy-duty axles, the 521G offers excellent stability when transporting heavy loads. It’s capable of tackling uneven terrain while maintaining operator comfort and minimizing material spillage.
CASE 521G Applications and Job Site Versatility
The CASE 521G is more than just a powerful wheel loader — it’s a multi-purpose machine built to thrive across a wide range of job site conditions. Its adaptability makes it a go-to solution for contractors and operators who need reliable performance in ever-changing environments.
Snow Removal
With its precision controls and strong hydraulic flow, the 521G is a top performer during winter months. When paired with snow pushers or blades, it easily pushes as large as a 17HD attachment without snow tires clearing parking lots, roads, and large commercial areas, even in slippery conditions.
Construction and Site Preparation
From loading gravel to leveling ground, the 521G handles daily demands with ease. Its lifting power and breakout force make it ideal for moving heavy materials or prepping construction zones for further work.
Municipal and Utility Work
Thanks to its compact design for its power class, the 521G is well-suited for municipal operations, including road maintenance, debris clearing, and utility support. It’s also favoured by public works departments for its reliability and low maintenance needs.
Attachment Compatibility
Whether you need a general-purpose bucket, pallet forks, or snow-specific attachments, the CASE 521G is built for flexibility. Its quick coupler system makes it easy to swap out attachments on the fly, increasing efficiency on the job site.
