Tracks are an important part of mini excavators. They give stability and mobility. We use them for safety because they lower the machine’s gravity center and can adjust to various conditions. Rubber tracks reduce noise, and steel ones handle heavy-duty workloads. We cannot avoid maintaining mini excavator tracks. Keeping up with mini excavator track maintenance is critical to how well the machine performs.

Daily Inspections and Cleaning

To-Do List

1. Visual Inspection

2. Cleaning the Tracks

3. Checking for Foreign Objects

4. Assessing Track Tension

5. Alignment Verification

6. Inspecting Track Bushings and Pins

7. Examining the Track Pads

8. Checking the Drive Sprocket

9. Looking for Oil Leaks

10. Monitoring Track Grease Levels

Rubber track on a mini excavator

Begin by visually checking the tracks. Look carefully for any damage, like cracks, cuts, or missing segments. Concentrate on the connections between track links and the undercarriage, as these areas are often vulnerable.

Take a stiff brush or high-pressure washer and clean the track, paying special attention to places around track pins and bushings where dirt can gather and make wear more pronounced.

Examine the tracks for any objects that are not part of the track itself, like small rocks or metal parts. These items can lead to holes or cuts in rubber and must be taken out from them at once.

The track tension needs to be checked and adjusted accordingly. Too much tension can cause the tracks to wear out quickly, whereas if they are not tight enough then slipping or coming off from the drive sprocket might happen.

Make certain that the tracks are in correct alignment with the centerline of the machine. If they are not, this could result in irregular wear and influence steering as well as tracking abilities of the mini excavator.

Examine the track bushings and pins. Observe for indications of wear like too much movement or stretched holes. Worn-out bushings and pins can cause track derailments.

Examine rubber pads for any indications of wearing out or harm. The thickness of the pads must be uniform, and they should not exhibit delamination or significant cuts.

Investigate the drive sprocket for signs of use or harm. Check if its teeth are complete and if there is no extreme looseness in the sprocket set.

Inspect for oil leaks in the track tensioning and idler wheel regions. Such leaks may suggest a necessary seal replacement.

Check if there is enough grease in the track system. Insufficient grease can cause more friction and wear out.

The Importance of Regular Maintenance

Prolonged Equipment Lifespan

Mini excavator maintenance can catch and solve problems early, greatly prolonging the life of tracks and undercarriage for your mini excavator. This not only saves money on a replacement but also lessens the environmental effect caused by disposing of parts regularly.

Enhanced Operator Safety

A mini excavator that is well taken care of will naturally be safer to use. If every part of it is in good working condition, there’s less chance for accidents or equipment breakdowns which could cause severe harm and even death.

Improved Work Quality

Tracks that are well-maintained give improved grip and steadiness. This results in more accurate handling during operations, potentially enhancing work quality and lessening the requirement for rework.

Increased Productivity

If your equipment is working well, it can complete tasks with less delay and improve productivity. The time when equipment is not available because of maintenance problems becomes smaller, enabling a steadier line of work.


Although maintenance could appear as an extra expense, it is similar to preventive action which can save money in the future. By not requiring big repairs or replacements, this method lets you manage your budget better.

Environmental Considerations

Another benefit of taking good care of your mini excavator’s tracks is it helps the environment. When you don’t have to change parts often, there will be less waste and also less need for new materials.

Upholding Equipment Resale Value

If you ever plan to sell your mini excavator, well-kept equipment is more appealing to potential buyers. No matter for a Chinese mini excavator or an American one, a comprehensive maintenance record can greatly enhance the selling price of your equipment.

Regulatory Compliance

In some fields of work, you must follow the law that asks for regular maintenance and checking of heavy machines to make sure they are safe and meet environmental rules. By following these needs, you can keep your business safe from legal consequences.

Minimizing Unforeseen Delays

Regular maintenance can assist in forecasting and preparing for equipment requirements, which may result in less unforeseen downtime. This planning is often important for satisfying project time limits and preserving a good standing within the field.

A mini excavator with steel tracks


It’s important to apply good rubber tracks. They increase flexibility and are starting to be more popular because they have advantages over steel tracks – less ground pressure and noise.

Not all surfaces need the same amount of traction. For instances where it is slippery or steep, tracks with deeper grouser designs or a more aggressive tread pattern are needed.

Normally, rubber tracks apply less force on the ground compared to steel. This characteristic makes them appropriate for softer or more delicate surfaces. On the other hand, even though steel tracks are stronger they can be utilized in harder terrains as well.

Picking the correct tracks will certainly show its value over time by making sure your machine is prepared to operate in its most efficient manner.


How long do rubber tracks last on a mini excavator?

The duration of rubber tracks on a mini excavator usually varies from 1,500 to 3,000 working hours. This depends on their application, care given, and quality.

The durability is the result of many factors like the ground condition, how much weight it carries, and how often there are sudden turns in direction. Cleaning them often together with maintaining correct tightness as well as timely greasing may help you make them last longer.

How do I know if my mini excavator tracks are worn out?

You should see if there are deep cuts, cracks, or holes in the rubber. Also, check for uneven wear and whether the track has become loose or not aligned properly. Listen carefully for any strange noises when it is operating. Inspect the thickness of the track.

If it is less than half its original size, it needs replacing. Moreover, when you observe a significant reduction in performance from the track leading to reduced traction and stability for your vehicle on uneven ground or hillsides then this indicates that the tracks are worn out and require replacement.

How do I stop my mini excavator tracks from squeaking?

When the tracks of a mini excavator start squeaking, this is commonly because they are dry or require lubrication. To halt the noise, it is important to have good lubrication on track pins and bushings using fitting grease. Keep checking for any dirt or rubble stuck in your tracks that may cause rubbing. Clean them frequently.

Verify no misalignments or tensions are causing uneven contact points, which can also lead to squeaking. If this does not resolve the issue, you may need to adjust the tracks or replace some worn parts.
