Bucket teeth, cutting edges, adapters and ripper shanks are the first point of contact with the ground. When these components wear down, machines must work harder to penetrate material — increasing engine load, hydraulic strain and ultimately fuel burn.

In this article, we explain how worn Ground Engaging Tools (GET) impacts fuel efficiency, productivity and overall machine health.

Why Ground Engaging Tools matter

Ground Engaging Tools are the working edge of your machine. From excavators and dozers to loaders and graders, GET determines how efficiently material is cut, penetrated, and moved.

At Jaytrac, we supply a full range of replacement Ground Engaging Tools (GET) for heavy-duty Caterpillar, Komatsu and Volvo machinery.

Using the correct tools — and replacing them before they are excessively worn — plays a direct role in maintaining fuel efficiency and reducing operating costs.

1. Reduced penetration increases engine load

Sharp, correctly profiled bucket teeth and cutting edges allow machines to penetrate material cleanly with minimal resistance.

When teeth become rounded or edges lose their profile:

• More force is required to enter the material
• Operators increase throttle to compensate
• Hydraulic systems work harder
• Cycle times increase

This results in higher fuel consumption per tonne moved.

Choosing the right configuration for your application is equally important. If you’re unsure which profile suits your job conditions, see our guide on how to choose the right bucket teeth for your job.
 

2. Longer cycle times burn more fuel

Worn GET reduces cutting efficiency. For example, buckets take longer to fill, and dozers require more passes to achieve the same result. Even a small increase in cycle time multiplied across hundreds of cycles per day significantly impacts fuel usage.

Fuel efficiency in earthmoving is measured as material moved per litre. When wear slows productivity but fuel burn remains constant (or increases), your cost per tonne rises quickly.

3. Increased rolling resistance on dozers and graders

On dozers and graders, worn cutting edges and end bits create uneven contact with the ground. This increases rolling resistance and forces the machine to push material rather than cut it cleanly.

Excessive drag:

• Raises engine RPM
• Increases transmission strain
• Accelerates tyre or undercarriage wear
• Drives higher fuel burn

Replacing worn edges before they compromise blade performance helps maintain optimal efficiency.

4. Hydraulic system strain and heat

When penetration becomes difficult, operators instinctively apply more hydraulic force. This increases pressure within the system and generates additional heat.

Higher hydraulic demand leads to:

• Increased fuel consumption
• Faster wear on pumps and hoses
• Elevated operating temperatures
• Greater long-term maintenance costs

Using high-quality aftermarket GET reduces stress across the entire machine.

5. Poor wear patterns lead to imbalance

Unevenly worn teeth or cutting edges can cause bucket imbalance, increased vibration, uneven load distribution and operator fatigue.

Imbalance forces the machine to compensate during digging and loading, increasing energy demand.

Routine inspections and understanding when to rotate or replace components is critical.

6. Fuel cost multiplies across the fleet

A single machine burning 5–10% more fuel due to worn GET may not seem significant. Across an entire fleet operating 8–12 hours per day, however, the additional cost becomes substantial.

Fuel accounts for a large proportion of total operating cost in quarrying and mining operations. Improving cutting efficiency directly improves fuel efficiency.

The importance of planned GET replacement

Replacing worn GET as part of scheduled maintenance delivers:

• Lower fuel consumption
• Faster cycle times
• Reduced machine strain
• Improved operator control
• Extended component life

Jaytrac has been supplying replacement GET and undercarriage parts for over 25 years, supporting heavy-duty fleets across the UK. We supply quality aftermarket components for leading brands including Caterpillar and Komatsu.

What are the signs your GET are increasing fuel consumption?

Look out for:

• Rounded or blunt bucket teeth
• Thinning cutting edges
• Uneven wear across blade surfaces
• Increased throttle usage during digging
• Longer cycle times
• Visible increase in fuel usage
