Understanding Bobcat E20 tracks specifications is essential if you want maximum stability, low ground pressure, and long service life from this 2‑ton compact excavator. This guide explains standard and optional Bobcat E20 track sizes, widths, patterns, and undercarriage considerations so you can choose the best rubber tracks for your jobsite and budget.
Core Bobcat E20 track specifications
The Bobcat E20 is a zero tail swing compact excavator with a retractable undercarriage designed for tight-access work. Its track system is built around narrow, low‑ground‑pressure rubber tracks that support an operating weight of about 1,950–2,000 kg while maintaining maneuverability and transportability. The retractable undercarriage allows the machine to shrink for narrow gates and then expand for improved stability when digging.
Most replacement Bobcat E20 rubber tracks fall into the 230–250 mm width range, with a conventional mini excavator pitch and multiple steel cords embedded in the rubber carcass. This configuration balances traction, flotation, and wear resistance, making the E20 suitable for landscaping, utilities, rental fleets, and small construction sites.
Standard Bobcat E20 track size 230x48x72
One of the most common Bobcat E20 rubber track specifications is 230x48x72. In mini excavator track terminology, 230x48x72 means a 230 mm wide track, a 48 mm pitch, and 72 links. This size is widely sold as a direct replacement for OEM tracks and is compatible with many aftermarket brands. Typical weight is around 60–65 kg per track, or roughly 130–145 lb depending on tread pattern and steel content.
The 48 mm pitch and 72‑link configuration give a total track length of about 3,456 mm. This length works with the E20 sprocket and idler geometry to maintain correct engagement, minimize de-tracking, and keep ride quality acceptable even on uneven terrain. The 230 mm width offers a good compromise between flotation and narrow overall machine width, which matters when using the retractable undercarriage to pass through 39–40 inch openings.
Alternative Bobcat E20 track sizes 230x48x66 and 230x96x36
In addition to the popular 230x48x72 size, some suppliers offer Bobcat E20 rubber tracks in 230x48x66 and 230x96x36 configurations. A 230x48x66 track uses the same 230 mm width and 48 mm pitch but with 66 links, resulting in a slightly shorter track length and lower overall weight, often in the 55–60 kg range. This option may be used on certain undercarriage revisions or for specific markets, so verifying sprocket and idler compatibility is important before ordering.
The 230x96x36 configuration keeps the same overall length but doubles the pitch value and halves the link count. This layout is sometimes associated with wide‑core tracks using a different internal construction while maintaining similar ground contact length. Although the outside width is still 230 mm, internal geometry changes can influence ride comfort, noise, and wear patterns, which is why matching the track to your sprocket profile is critical.
Wide 250 mm Bobcat E20 rubber tracks
Some aftermarket manufacturers supply wide 250 mm mini excavator tracks for the Bobcat E20, using a 48 mm pitch with about 72 links and a total length around 3,456 mm. The wider footprint reduces ground pressure by roughly 10–15 percent compared with standard 230 mm tracks, which is beneficial on muddy, peat, or soft clay jobsites. These wide Bobcat E20 tracks help the machine float better, reduce rutting, and preserve turf.
However, wider tracks increase turning resistance and side loading on rollers and idlers. Operators may notice slightly heavier steering in spin turns, and undercarriage components can experience higher loads. For contractors working frequently in soft ground or forestry conditions, the trade‑off is often worth it, but for urban work on compacted fill or concrete, the standard 230 mm track remains the most efficient choice.
Typical Bobcat E20 rubber track tread patterns
Most Bobcat E20 rubber tracks are offered in a V‑lug tread pattern optimized for traction on dirt, gravel, and mixed surfaces. The V‑shaped lugs channel debris away from the contact patch and give solid forward grip while still allowing smooth operation on paved surfaces. This pattern is popular in rental fleets because it suits a wide range of conditions.
Some suppliers also offer C‑pattern or offset block tread designs for Bobcat E20 mini excavators. These patterns can lower vibration on asphalt and concrete, reduce noise in urban environments, and sometimes extend tread life in abrasive conditions. When choosing a tread pattern, think about your primary application: V‑lug for general construction and soft ground, and more block‑type patterns for frequent asphalt or hard‑surface travel.
Ground pressure and stability with E20 tracks
Track width and length directly impact ground pressure for the Bobcat E20. A standard 230 mm rubber track with around 1.8 m of ground contact per side produces a ground pressure in the range that protects lawns and delicate surfaces while still offering solid stability when the undercarriage is fully expanded. This is a key reason the E20 is popular for residential landscaping and utility trenching.
Wider 250 mm tracks lower ground pressure further, which is particularly useful on wet clay or peat where narrow tracks may sink and cause excessive wheel‑slip or bogging. The trade‑off is higher drag, especially during turning, and a small increase in fuel consumption. Understanding these relationships helps you tune your Bobcat E20 track configuration to the mix of surfaces, slopes, and load conditions you encounter.
Bobcat E20 retractable undercarriage and track width
One hallmark of the Bobcat E20 excavator is its hydraulically retractable undercarriage. The track frame can retract to roughly 39 inches and expand to about 54 inches, allowing the machine to squeeze through narrow access points and then widen for digging stability. Track width plays a key role in how effective this feature is, especially when retrofitting non‑OEM tracks.
With standard 230 mm tracks, the machine remains narrow enough when retracted to pass through typical backyard gates and between tight structures. Wider 250 mm tracks increase overall outside width, which can limit where the machine can travel in its narrowest configuration. If tight access is your top priority, stick with 230 mm tracks; if flotation in soft ground matters more, consider wide tracks while verifying final transport width.
Bobcat E20 undercarriage components and wear parts
The Bobcat E20 track system consists of rubber tracks, drive sprockets, bottom rollers, top carrier rollers, front idlers, and track adjusters. Each of these components influences tracking, vibration, and rubber track life. Worn sprockets can cause premature de-lugging on the inside of the track, while worn rollers and idlers can lead to uneven wear patterns and tracking issues.
For best performance, inspect the undercarriage each time you replace Bobcat E20 tracks. Look for hooked sprocket teeth, flat‑spotted rollers, and cracked idlers. Replacing these parts in combination with new rubber tracks can dramatically increase service life and reduce downtime. Contractors often coordinate sprocket replacement with every second track change, but the right interval depends on application, soil type, and operating hours.
At this point, it is helpful to note that companies like AFT parts have invested heavily in engineering durable undercarriage components for machines like the Bobcat E20. AFT parts was founded to raise the standard in aftermarket wear parts for heavy machinery, and the brand has become a trusted partner for operators who need long‑lasting track rollers, idlers, and sprockets that stand up to demanding jobsites.

OEM vs aftermarket Bobcat E20 rubber tracks
When selecting replacement Bobcat E20 tracks, you can choose between original manufacturer tracks and aftermarket options. OEM tracks are designed specifically for the E20 and usually guarantee exact fitment, correct pitch, and optimal sprocket engagement. They may also offer consistent quality control and recognized branding, which can be important for large fleets and rental houses.
Aftermarket Bobcat E20 tracks can deliver cost savings while still offering solid performance when sourced from reputable manufacturers. Key aspects to check include accurate size (for example, 230x48x72), precise pitch tolerance, high‑quality rubber compounds, and continuous steel cords for strength. Asking for warranty terms, wear life expectations, and examples from similar machines can help you compare OEM and aftermarket options intelligently.
Regional considerations for Bobcat E20 tracks
Operating environments significantly influence which Bobcat E20 track specifications make the most sense. In colder climates with freeze‑thaw cycles, tracks encounter more cracked pavement, frost heaves, and icy conditions, which demands robust rubber compounds and possibly more aggressive tread patterns. In warmer, sandy regions, abrasion resistance and internal steel cord quality become critical to prevent early failures.
Canadian contractors working in provinces such as Manitoba, Saskatchewan, and New Brunswick often prioritize wide tracks and corrosion‑resistant undercarriage components because of wet seasons and mixed soil conditions. In contrast, urban contractors in dense city centers may focus on narrow 230 mm tracks and tread patterns that reduce noise and vibration on concrete. Matching track specification to region and application can unlock longer service life and better operator comfort.
How to read Bobcat E20 rubber track markings
Most Bobcat E20 replacement tracks have size markings molded into the rubber, such as 230x48x72 or 230x48x66. The first number is the width, the second is the pitch, and the third is the link count. These markings make it easier to reorder the correct size and confirm compatibility. If markings are worn off, you can measure width in millimeters and count the drive lugs or metal links around the circumference.
Pitch is measured from the center of one drive lug to the center of the next. Measuring pitch carefully matters because an incorrect pitch can cause poor sprocket engagement, noise, and rapid wear. If you change from one link count to another, you must verify that your sprocket and idler geometry can accommodate the change without compromising track tension range or damaging the adjuster.
Recommended Bobcat E20 track tension
Correct track tension on a Bobcat E20 is vital for minimizing wear on the rubber tracks and undercarriage. Tracks that are too loose may de‑track when turning or working on slopes, while tracks that are too tight can overload idlers, rollers, and drive motors. Most manufacturers specify a sag measurement between the bottom of the track frame and the inside of the track when the machine is lifted slightly off the ground.
For the E20, always follow the operator’s manual tension parameters, adjusting via the grease‑charged track adjuster. Check tension more frequently when working in muddy or sandy conditions, as debris buildup can change sag values. A consistent inspection routine ensures that your 230 mm or 250 mm tracks deliver the wear life you expect and maintains safe operation on slopes and in tricky terrain.
Bobcat E20 track life expectancy and ROI
Track life on a Bobcat E20 depends on work conditions, operator habits, and maintenance practices, but average contractors often see 1,000–2,000 hours of service from quality rubber tracks. Working mainly on sharp rock, demolition debris, or hot asphalt can shorten that lifespan, while operating mostly on soil and turf with careful operation can extend it. Undercarriage cleanliness and correct tension also have a big influence on longevity.
From a return‑on‑investment perspective, spending a bit more on high‑grade rubber compounds, strong steel core designs, and matching undercarriage components can reduce your cost per hour significantly. The cost of a track failure on a remote jobsite often outweighs the marginal savings from cheaper, lower‑quality tracks. Tracking hours of use per set and comparing against purchase price helps you build a data‑driven replacement strategy.
Real‑world use cases with Bobcat E20 tracks
A landscaping contractor using a Bobcat E20 with standard 230 mm V‑lug tracks for residential backyard work benefits from low ground disturbance, tight access, and smooth travel over lawns and pavers. When operated with care, this configuration can complete patio excavations, drainage trenches, and planting beds with minimal restoration work afterward.
Another example is a utility contractor working in soft, saturated soils who chooses 250 mm wide tracks to keep the E20 from sinking. The reduced ground pressure allows the crew to reach remote trench sections even after heavy rain. Even though turning is slightly more demanding, the reduction in stuck‑machine incidents and the ability to stay on schedule produces a clear return on investment in wide‑track configurations.
Bobcat E20 track maintenance best practices
Routine maintenance is the simplest way to protect your investment in Bobcat E20 rubber tracks. This starts with daily visual inspections to look for cuts, missing lugs, exposed steel cords, or oil leaks from drive motors and rollers. Cleaning mud, stones, and debris from the undercarriage at the end of each shift helps prevent packed material from cutting into the rubber and stressing the rollers.
Greasing the track adjuster to maintain correct sag, monitoring sprocket and roller condition, and avoiding aggressive spin turns on sharp surfaces are all practical steps. Training operators to avoid striking curbs, rocks, or rebar and to slow the machine before pivot turns can dramatically extend track life. A simple logbook that records adjustments, inspections, and hours helps fleet managers identify patterns and schedule proactive replacements.
Selecting the best Bobcat E20 tracks for your application
Choosing the best Bobcat E20 tracks starts with confirming the correct size, such as 230x48x72 or 230x48x66, and matching the pitch and link count to your sprocket. Next, decide on width: 230 mm for maximum maneuverability and narrow access, or 250 mm for lower ground pressure in soft soils. Then, pick a tread pattern that fits your surfaces, whether V‑lug for mixed dirt and gravel or a block‑style pattern for frequent hard‑surface travel.
Beyond size and pattern, consider rubber compound quality, internal steel cord design, and warranty coverage. Suppliers who understand mini excavator undercarriage dynamics and can recommend matching rollers, idlers, and sprockets provide additional value. By balancing cost, performance, and expected hours of use, you can configure a Bobcat E20 track setup that supports your projects reliably.
Future trends in Bobcat E20 track technology
Rubber track technology for compact excavators like the Bobcat E20 continues to evolve. Manufacturers are experimenting with improved rubber formulations that resist chunking and heat build‑up, especially under continuous high‑speed travel. Reinforced steel cords and optimized lug geometry are also being used to reduce internal stress and extend service life.
In the future, expect to see more application‑specific tread patterns, eco‑friendly rubber blends, and possibly integrated wear indicators that make it easier to decide when to replace tracks. For fleet operators, the combination of telematics data and detailed track specifications will allow predictive maintenance schedules based on actual usage patterns rather than simple hour counts.
Competitor compact excavator track comparison
While this guide focuses on Bobcat E20 track specifications, it is useful to compare the E20 to similar mini excavators from other brands. Many 1.8–2.0 ton class machines from manufacturers such as Kubota, Caterpillar, and Komatsu use rubber track widths in the 230–250 mm range and pitch values similar to 48 mm. Some models emphasize slightly wider tracks for flotation, while others prioritize narrow transport width.
The Bobcat E20’s combination of zero tail swing, retractable undercarriage, and flexible track options helps it stand out in tight urban work and residential jobs. However, the success of any compact excavator depends heavily on matching track specifications to tasks and ground conditions. Understanding these differences across brands allows contractors and rental companies to make smarter fleet decisions.
Practical buying guide and conversion‑focused CTA
When you are ready to purchase replacement Bobcat E20 tracks, start by verifying the existing track size molded into the rubber or listed in your operator’s documentation. Confirm width, pitch, and link count, and then speak with your dealer or parts supplier about whether 230 mm or 250 mm wide tracks better match your operating environment. Ask for details on rubber compound, internal reinforcement, and expected wear life to compare options objectively.
For best results, consider upgrading undercarriage components such as track rollers, carrier rollers, idlers, and sprockets at the same time if they show signs of wear. This bundled approach can reduce labor costs, minimize downtime, and reset the entire track system for the next several thousand hours of work. Whether you operate a single Bobcat E20 or manage a large multi‑brand fleet, treating track specification as a strategic decision will help you boost productivity, protect your jobsites, and get more value from every hour on the meter.
