Is your excavator not working and you aren’t sure why? Common excavator problems, such as a disconnected battery or clogged fuel lines, prevent the machine from working properly. But don’t worry; we’re here to help. Let’s take a closer look at what excavators are used for, common excavator problems, and how to address them to restore operation.

Top Uses of Excavators
Earthmoving
Excavators have attachments with teeth-like edges that allow them to dig up dirt and other materials from the ground. Two common earthmoving applications include digging trenches and grading landscapes.
- Trench digging: Excavators dig trenches to lay foundations, install wires and pipe systems, and plant seeds for agricultural purposes. Digging trenches with an excavator is much quicker than doing so manually.
- Landscape grading: Excavators grade, or level, landscapes to prepare them for various construction projects.
Material Handling
Operators can attach a clamp to the end of an excavator to dig up and transport materials that otherwise would not fit in the bucket. Excavators can also be equipped with taller cabs and heavier counterweights to maximize visibility and stability for material handling.
Demolition
Excavators with a breaker attachment can be used for demolition purposes. This attachment is durable enough to break through concrete, stone, and other hard materials without sacrificing stability or safety.
Underground Excavation
Underground excavation, also called tunneling, is the process of digging underground to form passageways. Operators can use a bucket and hydraulic auger attachments to dig deeper and faster than they could with just a bucket.
Underwater Operations
Some excavators are created specifically for underwater applications, such as digging holes for bridge posts and tunnels for pipe systems. These excavators are equipped with attachment arms and roller chains that make navigating underwater environments easier.
Forestry
Excavators equipped with shears, mulchers, and other attachments are used to clear paths, trim trees, and remove other obstacles in the forestry industry.
Debris Removal
Excavators aren’t just used to remove dirt and other materials. They’re also used to remove debris. Buckets, clamps, and other tools can be attached to the excavator to remove materials such as concrete and wood.
How Hard Is It to Operate an Excavator?
Operating an excavator is no more difficult than operating another piece of heavy equipment. Plus, it gets easier over time with proper training and practice. The more you operate an excavator, the more confident you will be doing it.

Common Reasons Why an Excavator Won’t Start
Excavator Won’t Crank (Nothing Happens or Just Clicks)
- Dead or weak battery, or corroded or loose terminals
- Hydraulic lockout lever not in the locked position. Many excavators won’t start unless the safety lever is up or locked. This is one of the most common “won’t start” causes and is completely missing from the page. Confirm with an instructor.
- Blown fuse or failed relay
- Faulty key switch or anti-theft immobilizer
- Bad starter or starter solenoid
Excavator Cranks but Won’t Start
- Out of fuel, or air in the fuel system after running dry. The fuel system needs to be bled.
- Clogged fuel filter, or water in the fuel
- Gelled diesel in cold weather
- Failed glow plugs or intake heater
- Faulty fuel shutoff solenoid
What to Do When an Excavator Frequently Fails to Start
Consult the Operator’s Manual
Every excavator comes with an operator’s manual. This document contains valuable information such as how to operate it, take care of it, and troubleshoot common excavator problems. If you notice the starter isn’t working, the battery is dead, the wiring is faulty, or something else, consult the operator’s manual.
Contact a Service Technician
If the owner’s manual doesn’t have the answers you need, contact a service technician who can identify the problem and provide a solution. Whether your excavator simply needs routine maintenance or more in-depth repairs, they can help you. Be sure to contact a technician as soon as you notice a problem to minimize damage to your equipment.
