Features

Solid Performance in a Small Package – Compact and efficient design provides superior power.

Compact Radius

This mini hydraulic excavator provides solid performance in a small package.
Transport
With an operating weight of 3048 kg (6,721 lb) and width of 1550 mm (60 in) the 303E is simple to load and position on a trailer with tie down points – getting you to the job site quicker.
Fuel Economy
Powered by the C1.3 engine, the 303E offers the performance and power required for your job with minimal fuel consumption.

Productivity and Durability – Designed for reliability.

Auxiliary Hydraulics
The 303E is ready to work. Hammer and two way lines with quick disconnect fittings are standard on every machine.
The 303E CR is productive, durable, and ready to work.
The quick disconnects are located close to the tool to reduce hose length and decrease owning and operating costs associated with hose replacement.
Hose routings provide superior protection and cylinder guards decrease opportunity for machine damage.
Thumb Ready Stick
The machine is configured with brackets and relief valves for simple and cost effective mounting of a hydraulic thumb.
Dozer Blade
The durable blade and dozer float function provide the required design and capability to increase overall efficiency. Ground leveling and finishing applications are fast and easy with a single lever controlling all blade operation – up, down and float.

Superior Operating Experience – Safety and comfort all day.

Spacious and Ergonomic Working Environment
Your safety and comfort is incorporated into the design of every Cat® machine.
This working environment is spacious and ergonomic.
The adjustable suspension seat, retractable seat belt and adjustable wrist rests allow you to customize the operating station to meet your needs. Ergonomically designed joystick control and travel levers reduce fatigue and improve productivity.
An easy to use pattern control selector and informative gauge panel ensure optimal operation.
