Benefits

Sustainability

The Cat® C7.1 engine meets U.S. EPA Tier 4 Final, EU Stage V and Korea Tier 5 emission standards.
Engine Idle Management System (EIMS) helps maximize fuel efficiency and reduce greenhouse gas emissions while maintaining machine performance.
Engine Idle Shutdown Timer reduces fuel burn, greenhouse gas emissions and unnecessary idle time by shutting down the machine after a pre-set idling period.
Performance Series Buckets have rounded side boards, a longer floor and open angle to carry more and load quicker so each pass is the most efficient.
Rimpull Control is a quick way to adjust the torque to the tires for less slipping and tire wear.
Cat® Production Measurement provides real-time payload weighing which help you maximize productivity, reduce fuel burn and greenhouse gas emissions, all while improving job site efficiency and lowering costs.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
Power on Demand, transparent to the operator, provides full-time efficiency and power when you need it.
Tire Pressure Monitoring provides real-time tire pressure information to the operator to help increase tire wear and achieve better fuel efficiency and reduced greenhouse gas emissions.
Intelligent Hystat Transmission helps improves control and reduces fuel consumption and greenhouse gas emissions in load and carry applications.
Variable Displacement Pumps match power to load as application requirements change.

Purpose Built: Handlers Arrangements - Waste Handler

Guard Your Investment: Choose from a complete range of optional guarding to protect your machine from the harsh environment of a waste handling application. Machine guarding is purpose built to protect the machine’s major components.
Breathe Clean: Maximize your engine life and extend filter cleaning intervals with a turbine pre-cleaner. Keep cool with a reversing fan to purge the single plane, widely spaced core cooling package and brush-less sealed alternator. Breathe clean with a powered pre-cleaner for the operator environment.
Maximize Tire Life: Fine tune your wheel torque to match the underfoot conditions and maximize performance while extending tire life. Standard auto wheel torque and auto differential lock are ideal for waste handling applications.

Purpose Built: Handlers Arrangements - Aggregate Handler

Increased Payload: Additional counterweight improves stability without reducing ground clearance or departure angle to maximize performance.
Long Life Sand and Gravel Buckets: Performance series buckets deliver higher fill factors and better material retention for significant productivity and fuel efficiency improvements. Buckets feature a long floor, open throat, curved side bars and additional serviceable wear plates including corner guards.
Protect your Power Train: Increase your fording depth with optional elevated breathers. Remote mounted high on the machine for the front and rear axles and hydrostatic gear box. Allows settling pond cleanout without contamination.

Upgrades and Services

Enjoy a full range of upgrades and accessories to configure your small wheel loader for a broader range of applications.
Utilize readily available services and maintenance parts, including a range of self-service options (SSO) and dealer installed kits.

Customize Your Experience

Meet your application requirements and individual preferences with Caterpillar industry first Hystat™ Operator Modes featuring four unique power train settings. Select classic torque converter for smooth rollout, conventional hystat for aggressive engine braking, an ice mode that maximizes your control on slippery underfoot, and an all new single pedal mode for simplified use.
Fine tune machine performance with adjustments at your fingertips through programmable joysticks, soft touch buttons, and a new jog dial that works in combination with a standard touch screen display. Quickly recall attachment profiles that maintain key settings for versatility on the jobsite and optimal efficiency.

Work Made Easy

Move more with the Caterpillar patented quick loading performance series buckets and optimized Z-bar linkage with enhanced forward visibility that combines the digging efficiency of a traditional Z-bar with tool carrier capabilities. The parallel lift and high tilt forces throughout the working range allow you to confidently handle loads with precise control.
Multi-function work has never been easier with dedicated pumps for each system and a flow sharing implement valve governed by an intelligent power management system. Simultaneously lift, steer, and drive without compromise. Upgrade to autolube and tire pressure monitoring to make service easy and get to work quicker. Light the way with auto roading lights that come on at night fall.

Efficiently Powerful

Experience the difference with an intelligent hydrostatic power train and industry leading fuel savings through a lower maximum engine speed working in combination with a new auto engine RPM mode. This provides efficiency as standard with a boost in power when you need it. Optimize traction and minimize wheel slip with a new Auto Wheel Torque system tuned to provide peak performance while maximizing tire life and keeping operating costs low. Track your production and accurately hit your load targets with Cat Payload. 250 hours of Cat Payload demonstration will be included as standard with an optional subscription for extended use.

Enjoy All Day Comfort

Have a seat in the new Cat small wheel loader and enjoy automatic temperature control, class leading sound levels, enhanced all-around visibility and low-effort joystick controls that move with you on a fully adjustable seat suspension. A large spacious operator environment combined with Caterpillar hydraulic cylinder damping and smooth predictable controls make this the most comfortable seat on your jobsite.
An upgrade to multi-view camera and rear object detection gives you an extra eye on the jobsite while the new optional force feedback joystick steering keeps you feeling confident on those long shifts. The operator not present function helps to isolate the machine if you leave the environment; while seat belt notifications give you a gentle reminder to buckle up.
