Many contractors ask whether you can put rubber tracks on a steel track excavator without compromising performance, safety, or undercarriage life. The reality is that a direct swap is rarely plug and play, but with the right conversion strategy, rubber track solutions and rubber pads can turn a steel tracked excavator into a surface-friendly, versatile machine for urban, roadwork, and landscaping jobs.
Can You Put Rubber Tracks on a Steel Track Excavator?
From a technical standpoint, you cannot simply remove steel shoes and slip on continuous rubber tracks without checking undercarriage compatibility. The sprockets, track rollers, carrier rollers, idlers, and track frame of a steel track excavator are designed around the geometry and stiffness of steel track chains and steel shoes, not molded rubber track belts. On many medium and large excavators, the drive lugs, pitch, and rail profile of rubber tracks will not properly mesh with steel undercarriage components and can lead to de-tracking, accelerated wear, and safety risks.
However, there are three main ways a steel track excavator can achieve rubber contact with the ground. First, hybrid systems using bolt-on rubber pads or clip-on rubber pads attach directly to steel track shoes to create a rubber running surface while retaining the steel chain and steel undercarriage. Second, removable roadliner pads bolt directly to the steel chain as one-piece rubber pads, replacing the steel shoes for semi-permanent rubber operation. Third, true rubber track conversions are sometimes possible on smaller mini excavators and midi excavators when the undercarriage is designed to accept both iron and rubber, or when a complete undercarriage conversion kit is installed.
In practical terms, for most conventional steel track excavators, the best way to “put rubber tracks on” is to install rubber track pads on the existing steel tracks rather than replacing the entire system with continuous rubber belts.
How Rubber Track Conversions and Rubber Pads Work
To understand if your steel track excavator can be converted, you need to look at the undercarriage layout and the size class of the machine. Mini excavators and some midi excavators in the 1–10 ton range are more likely to have cross-compatible undercarriage designs that allow swapping between rubber tracks and steel tracks with minimal changes. These machines may share sprocket pitch and roller profiles that match both rubber and steel options.
Larger crawler excavators in the 13–30 ton range and above typically use permanent steel chains and steel shoes, making a full rubber track belt swap unrealistic without replacing sprockets, rollers, idlers, and sometimes track frames. For these machines, rubber pad systems are the preferred solution. Bolt-on rubber pads fasten through pre-drilled holes in the steel shoes, clip-on rubber pads clamp over the shoes, and roadliner pads bolt directly to the chains to create a wide, durable rubber contact area.
These rubber pad systems let you retain the strength, tensioning system, and load distribution of steel tracks while upgrading the contact surface to rubber. The result is a steel track excavator that can work on asphalt, concrete, pavers, and other finished surfaces with far less risk of damage, noise, or vibration.
Market Trends for Rubber Tracks and Rubber Pads on Excavators
The market for rubber tracks, rubber track pads, and hybrid steel-and-rubber undercarriage systems has grown rapidly in urban construction, road maintenance, utility installation, and landscaping segments. Contractors, municipal fleets, and rental companies are under increasing pressure to minimize damage to roads, sidewalks, parking lots, and driveways, which pushes demand for surface-friendly excavator undercarriages. Noise regulations and community expectations are also encouraging the switch from pure steel tracks to rubber solutions.
Aftermarket reports and equipment fleet surveys show a steady rise in orders for bolt-on rubber pads, clip-on pads, and roadliner pads for steel track excavators in the 4–26 ton class, particularly in regions with dense urban infrastructure and aggressive road protection requirements. Many rental houses now standardize on rubber track mini excavators and steel track excavators equipped with rubber pads as versatile, jobsite-friendly options that can go from dirt to pavement without downtime.

Benefits of Adding Rubber Tracks or Rubber Pads to Steel Track Excavators
When you convert a steel track excavator to operate on rubber, either through rubber tracks or rubber pads, you gain a long list of operational benefits. First, you dramatically reduce surface damage to asphalt, concrete, pavers, and decorative hardscapes. Steel grouser shoes can chip, scratch, and crush fragile surfaces, while rubber distributes load more evenly and grips without gouging. Second, rubber significantly reduces noise levels and vibration transmitted into the cab. This improves operator comfort, cuts fatigue, and makes it easier to meet local noise ordinances in residential and urban areas.
Third, rubber provides better traction on certain hard or wet surfaces compared with bare steel shoes, helping prevent slippage during slewing, digging, and lifting. Fourth, rubber pads can lower maintenance costs by reducing the need for temporary ground protection mats, plywood, and surface restoration after the job. Finally, the ability to move your steel track excavator across roads, driveways, and parking lots without a lowboy trailer can improve mobility and jobsite efficiency.
These benefits are why many owners of steel track excavators are adding bolt-on rubber pads, clip-on pads, or roadliner pads rather than buying a separate rubber track machine.
Types of Rubber Pad Systems for Steel Track Excavators
When evaluating how to put rubber tracks on a steel track excavator, it helps to understand the main types of rubber pad systems available in the aftermarket.
Bolt-on rubber pads are one of the most popular options. Each pad bolts through the existing holes in the steel shoes. This design keeps the original steel shoe in place, using the rubber pad as the ground-contact layer. Bolt-on rubber pads are ideal for semi-permanent conversions where the excavator will spend a lot of time on paved or improved surfaces. They offer a secure fit and a wide rubber footprint while retaining the support of the steel shoes.
Clip-on rubber pads, sometimes called clamp-on pads, attach over the steel shoes with side brackets and clamps. These are well-suited for contractors who need to convert frequently between pure steel and rubber contact. Clip-on pads can be installed and removed faster than bolt-on pads because they do not require shoe bolt removal. They are a great choice for short-term jobs in cities, residential neighborhoods, and industrial plants where surface protection is critical.
Roadliner pads are one-piece rubber pads that bolt directly to the track chain and replace the steel shoes altogether. They effectively create a rubber running surface with steel chain support. Roadliner pads are often used on excavators in the 4–26 ton range that frequently work on roads, bridges, and concrete hardstands. This style provides a clean rubber footprint and is considered one of the most cost-effective solutions for converting a steel track excavator to rubber for long-term pavement work.
Table: Common Rubber Pad Options for Steel Track Excavators
| Pad Style | Key Advantages | Typical Ratings | Ideal Use Cases |
|---|---|---|---|
| Bolt-on pads | Strong, secure fit; semi-permanent; uses shoe bolt holes | Heavy duty, long life | Roadwork, utility trenching, urban construction |
| Clip-on pads | Fast install and removal; no shoe bolt changes | Medium to heavy duty | Short-term jobs on asphalt and concrete |
| Roadliner pads | One-piece design; bolts to chain; clean rubber footprint | Heavy duty | Frequent highway work, bridge jobs, industrial yards |
| Polyurethane pads | Higher abrasion resistance than rubber in some soils | Heavy duty | Milling machines, pavers, high-wear industrial sites |

Core Technology: How Steel Track and Rubber Systems Interact
Putting rubber tracks on a steel track excavator is about more than simply changing the tread material. The undercarriage system is an engineered assembly where sprocket pitch, bushing diameter, roller profile, shoe width, and track tension all work together. On a steel track excavator, the chain and pins carry high loads, and the steel shoe transfers these loads to the ground with grousers that bite into soil and rock.
Continuous rubber tracks are molded with embedded steel cords and drive lugs shaped to match specific sprocket tooth profiles. If the sprocket and roller geometry do not match the rubber track’s pitch and lug shape, you can see premature wear, jumping, or de-tracking. This is why most heavy steel track excavators cannot accept generic rubber tracks without a dedicated conversion kit that includes compatible sprockets, rollers, and idlers.
Rubber pad systems bypass this mismatch by leaving the steel chain and sprockets intact while adding a rubber wear surface to the steel shoes or track chain. The rubber pads are usually made of high-tensile rubber or polyurethane bonded to steel plates. These pads distribute load across the steel shoes, absorb vibration, and provide a softer interface between the machine and the ground, all while keeping the heavy-duty steel undercarriage working as designed.
When Does a Rubber Track Conversion Make Sense?
Deciding whether to put rubber tracks on a steel track excavator depends on your work mix, jobsite conditions, and fleet strategy. If the machine spends most of its time in demolition rubble, quarry rock, or abrasive, sharp-edged environments, pure steel tracks will still provide the best durability and resistance to chunking and tearing. Rubber tracks and rubber pads can be damaged by rebar, metal scrap, and sharp concrete edges, leading to premature failure and higher replacement costs.
Conversely, if you frequently cross asphalt streets, concrete parking lots, stamped concrete, or interlocking pavers, adding rubber pads can quickly pay for itself. Reduced surface repairs, fewer complaints from property owners, and lower spending on temporary ground protection make hybrid steel-and-rubber systems very attractive. Many contractors keep one or two key excavators outfitted with bolt-on or roadliner pads specifically for municipal work, utility digs, and high-end landscaping projects.
For mini excavators that are primarily used in urban infill, backyard access, and indoor or tight commercial spaces, a full rubber track machine or a steel track mini excavator converted to rubber tracks is often the best choice. These smaller machines benefit from lower ground pressure, quiet operation, and the ability to work close to buildings, foundations, and finished surfaces without causing damage.
Real User Cases: ROI from Rubber Pads on Steel Track Excavators
Consider a contractor running a 15-ton steel track excavator on road reconstruction projects. Initially, the machine required plywood sheets or rubber mats to protect asphalt and concrete when working near completed sections of the road, adding labor and material cost on every job. After installing bolt-on rubber pads across both steel tracks, the contractor reported less surface damage, eliminated the need for temporary protection on many jobs, and reduced cleanup time at the end of each project.
Another user case involves a utility contractor performing water and sewer repairs in residential neighborhoods. Before adding rubber pads, they frequently received complaints from homeowners about scratched driveways and damaged curbs. After converting the steel track excavator to roadliner rubber pads, they saw a drop in complaints, fewer damage claims, and faster approvals for future projects from local municipalities. The direct savings from fewer claims combined with higher customer satisfaction created a measurable return on investment over a single season.
A rental company also saw strong ROI by offering a steel track excavator equipped with clip-on rubber pads as a premium option. Customers working on mixed surfaces appreciated being able to remove the pads for rough ground and reinstall them for driveway or parking lot work. Higher rental rates and better fleet utilization made the investment in rubber pad kits worthwhile.
Installation Considerations: What You Must Check First
Before attempting to put rubber tracks or rubber pads on a steel track excavator, you should perform a detailed undercarriage inspection and compatibility check. Confirm the track shoe width, bolt pattern, and hole spacing to ensure that bolt-on or clip-on pads will fit correctly. Verify the chain pitch, number of shoes per side, and track tension range to make sure roadliner pads can be installed without interference.
You should also inspect rollers and idlers for wear, as excessive wear can affect pad fitment and contact. On mini excavators where a full rubber track conversion is being considered, check the manufacturer’s documentation to see if the model is designed to accept both steel and rubber tracks. Some machines require different sprockets or roller profiles when changing between steel and rubber. Ignoring these recommendations can cause excessive noise, track jumping, or shortened undercarriage life.
Finally, consider ground clearance and machine width when adding rubber pads. Bolt-on and clip-on pads can slightly increase overall track width and change the way the machine interacts with curbs, barriers, and trailer ramps. Plan accordingly and ensure transport equipment, tie-down points, and clearances still comply with regulations and jobsite constraints.
Future Trends in Rubber Track and Pad Technology for Excavators
The future of putting rubber tracks on steel track excavators is moving toward smarter, longer-lasting hybrid systems. Manufacturers are developing rubber compounds with better resistance to chunking, tearing, and heat, making rubber pads more suitable for heavy, continuous-duty cycles. Advanced bonding techniques between rubber and steel plates are improving pad life and reducing the risk of delamination.
There is also a trend toward modular pad designs that simplify installation and replacement, letting contractors swap pads quicker between jobs or rotate worn pads to extend life. Smart undercarriage monitoring with telematics and sensor-based wear tracking is beginning to influence maintenance strategies, helping fleet managers schedule pad replacements and undercarriage service before failures cause downtime.
As regulations tighten around road damage, noise, and vibration in city centers and sensitive environments, demand for rubber pad-equipped steel track excavators is likely to continue rising. More OEMs and aftermarket suppliers are offering factory-approved pad systems and undercarriage packages that make it easier to specify a machine that can confidently work on both rough ground and delicate surfaces.

FAQs: Rubber Tracks and Rubber Pads on Steel Track Excavators
Can you put rubber tracks on any steel track excavator?
You can often add rubber pads to many steel track excavators, but a full continuous rubber track conversion is only practical when the undercarriage is compatible or a complete conversion kit is available.
Is it better to use rubber pads or full rubber tracks?
For most mid-size and large excavators with steel chains, rubber pads on steel tracks are the most practical solution, while mini excavators often work best with full rubber tracks.
Will rubber pads reduce the lifting capacity of a steel track excavator?
Rubber pads do not significantly change the structural lifting capacity, but they can slightly affect traction and stability on certain surfaces, so operators should follow the machine’s load charts and use caution.
How long do rubber pads last on a steel track excavator?
Pad life depends on the material, jobsite conditions, and operator technique; on typical mixed-use jobs, high-quality pads can last through many projects before needing replacement.
Can you still work off-road with rubber pads installed on steel tracks?
Yes, many contractors use rubber pads on dirt and gravel, but extremely sharp rock, scrap metal, or demolition debris can shorten pad life, so some operators remove pads for the harshest conditions.
Conversion-Focused Guidance: Choosing Your Next Step
If you rely on a steel track excavator for a mix of dirt work and pavement or concrete projects, upgrading to rubber pad systems is one of the fastest ways to expand your job opportunities with the same machine. Start by assessing how often you work on finished surfaces and calculate the cost of damage repairs, temporary matting, and customer complaints. For frequent urban or municipal work, a semi-permanent solution like bolt-on or roadliner pads provides strong value and consistent surface protection.
For contractors with more occasional city jobs, clip-on pads offer a flexible way to convert a steel track excavator when needed and revert to bare steel tracks for heavy, abrasive ground conditions. Fleet managers and rental companies can differentiate their offerings by stocking at least one steel track excavator equipped with a complete rubber pad kit ready for road-sensitive projects.
As you plan your undercarriage strategy, consider consulting undercarriage specialists and aftermarket pad suppliers who understand both steel and rubber technology. With the right combination of steel tracks, rubber pads, and compatible undercarriage components, you can confidently put rubber contact on a steel track excavator and unlock cleaner, safer, and more profitable operation across a wider range of jobsites.
