Compact Radius

Work with greater confidence in tight quarters

Less Tail

The demand for excavators capable of working in tight quarters continues to grow, and Caterpillar is meeting the need – from the mini 301.7D CR all the way up to the new 335F L. The market’s largest compact radius machine will help you take on some of the heaviest up-close work with confidence knowing you won’t hit a wall or an oncoming vehicle when you swing because it has only six inches of overhang.

More Stability

The 335F L utilizes the long, heavy-duty undercarriage from the large 336F excavator. Measuring 5020 mm (16'6"), this platform provides much greater stability when lifting heavy objects, which leads to greater overall productivity.

Better Lift

The 335F L is designed to deliver greater lift capability out front and over the side than the model it’s replacing. Two major contributors are increased hydraulic pressure and flow.

Integrated Technologies

Monitor, manage, and enhance your job site operations

Cat Connect

The smart use of technology and services will improve your job site efficiency. In fact, using data from technology-equipped machines gives you more information and insight into your equipment and operations than ever before.

LINK Technologies

LINK technologies like Product Link™ wirelessly connect you to your equipment, giving you valuable insight into how your machine or fleet is performing. The system tracks location, hours, fuel usage, productivity, idle time, and diagnostic codes through the online VisionLink® interface so you can make timely, fact-based decisions to maximize efficiency, improve productivity, and lower operating costs.


Power to move your material with speed and precision

Ground-Breaking Design

When it comes to moving heavy material quickly and efficiently, you need hydraulic horsepower – the type of ground-breaking power the 335F L can deliver. Major hydraulic components like the main pump and main control valve are located close together so shorter tubes and lines can be used. This design leads to less friction loss, reduced pressure drops, greater fuel efficiency, and more power to the ground for the work you need to get done.

Control Like No Other

Controllability is one of the key attributes of Cat excavators, and one of the main contributors to this is the main control valve. The valve opens slowly when your joystick lever movement is small and opens rapidly when movement is high. It directs flow where you need it when you need it, which leads to smoother operation, greater efficiency, and lower fuel consumption.

Tool Control Above The Others

Caterpillar’s standard tool control system gives you just the right amount of pressure you need to work with a variety of tools, including rotating grapples, shears, and multiprocessors. Unique to Cat machines is the ability for you to pre-program up to 10 different tools through the machine’s monitor to make switching for the job at hand simple and easy to do, which will save you time and money compared to other brands’ manual systems.

Auxiliary Hydraulics For Added Versatility

Auxiliary hydraulic circuits give you added versatility, and there are several factory-installed options from which you can choose. You can have a single function circuit to run a hammer and compactor or a double function circuit to run a thumb or tilt bucket. A quick coupler circuit allows you to switch from one tool to another in a matter of minutes – all from the comfort and convenience of the cab.

Boom and Stick Oil Re-Circulation For Added Efficiency

The 335F L regenerates the flow of oil from the head end of the boom and stick cylinders to the rod end of the boom and stick cylinders during the work cycle to save energy and improve fuel efficiency. It’s optimized for any dial speed setting you select, which results in less pressure loss for higher controllability, more productivity, and lower operating costs for you.


Powerful and fuel efficient to meet your expectations

Proven Technology

Every Tier 4 Final ACERT engine is equipped with a combination of proven electronic, fuel, air, and aftertreatment components. Applying these time-tested technologies lets us meet your high expectations for productivity, fuel efficiency, reliability, and service life. Following are the results you can expect:

  • Better fuel economy with minimized maintenance costs.
  • Same great power and response.

Fuel Savers That Add Up

The 335F L consumes up to 16% less fuel than the D Series model it’s replacing, and lowering engine speed without impacting production is one of the key contributors. Automatic engine speed control also contributes by lowering rpm when the machine doesn’t need it for work. Automatic engine idle shutdown turns the engine off when it’s been idling for more than a specified amount of time that you can set through the monitor. Plus you have a choice of three power modes – high power, standard power, and eco mode. Simply change between modes through the console switch panel to meet the work needs in front of you. Collectively, all of these benefits add up to lower fuel consumption, less exhaust and sound emissions, reduced repair and maintenance costs, and increased engine life for you.

A Cool Design For Any Temperature

The machine’s cooling system is built to work in extreme conditions. The system is completely separated from the engine compartment to reduce noise and heat. Plus it features easy-to-clean cores and a variable-speed fan that runs only when needed to ensure maximum efficiency.

Biodiesel Not A Problem

The C7.1 ACERT engine can run on up to B20 biodiesel that meets ASTM 6751 standards – all to give you more potential fuel-saving flexibility.

More Powerful, Reliable Engine Electronics

Cat Tier 4 Final engine electronics are more powerful and robust than ever, enhancing your experience and increasing quality and reliability through the most demanding applications.

Next Generation Fuel Systems

Injection timing precisely controls the fuel injection process, which provides more control of combustion for the cleanest, most efficient fuel burn. To maximize your value, Caterpillar engineers specified fuel systems based on the power and performance demands for each engine. The high-pressure common rail fuel system with full electronic injection improves precision and control, reducing soot and boosting the engine’s performance.

Innovative Air Management

Cat Tier 4 Final engines feature innovative air management systems that optimize airflow and enhance power, efficiency, and reliability. A range of simple, reliable turbo charging solutions based on engine size and application allows us to match turbo performance to rated output for high productivity, excellent fuel efficiency, long life, and low operating costs for you.

Cat NOx Reduction System

The Cat NOx Reduction System captures and cools a small quantity of exhaust gas and then routes it back into the combustion chamber to drive down temperatures and reduce NOx emissions. The result of more than a decade of Caterpillar engineering research into this technology is the most reliable system of its type.

Aftertreatment Technologies

The aftertreatment solution utilized for Tier 4 Final products is the next evolutionary step for Cat engines with ACERT Technology. To meet the additional 80% reduction in NOx emissions required by Tier 4 Final emission standards, Caterpillar engineers only needed to add one new system to the already proven aftertreatment solution in use, Selective Catalytic Reduction (SCR).

Diesel Exhaust Fluid (DEF)

Cat engines equipped with an SCR system inject DEF into the exhaust to reduce NOx emissions. DEF is a precisely mixed solution of 32.5% high purity chemical grade urea and 67.5% de-ionized water. DEF used in Cat SCR systems must meet the requirements outlined in the International Organization for Standardization (ISO) standard 22241‑1. ISO 22241-1 requirements are met by many brands of DEF, including those that carry the AdBlue or API certifications.

An Emissions Solution That Works

The Cat C7.1 ACERT engine meets Tier 4 Final emission standards, and it does so without interrupting your job process. Simply turn the engine on and go to work.
