Rubber Track 16″ 400 x 74 x 72 (New Holland / Kobelco)
Brand: National 1 Track & Parts
Size and fit: 400 x 74 x 72, compatible with New Holland E50B, E50B variants, and Kobelco SK-series models listed in the product name. The track is designed to match the common 400×72/400×74 class by providing a near-matching cross-section for stable ride and even wear. This option is best for operators seeking a straightforward replacement with predictable performance.
Why chosen: It aligns with the 400×74 target, offering a balance of stiffness and flexibility for typical construction terrain. Best for users prioritizing fit with New Holland and Kobelco models in the 50-series family.
Limitations: Specific fit checks are still recommended for non-listed SK-series iterations to avoid misfit in edge conditions.
What to watch for: Ensure the mounting geometry and wheel alignment match your machine’s spec to maximize track life and avoid tension issues.
NRP Rubber Track V Tread 400×72.5×74
Brand: NRP
Size and fit: 400×72.5×74, designed for Bobcat, Hitachi, John Deere, Kubota CT50N/E-series, and other brand models listed. The V tread adds grip suitable for varied terrains including muddy and loose surfaces.
Why chosen: This track emphasizes traction and longevity with a tread pattern engineered for a mix of surfaces, making it a strong all-terrain option for compact machines.
Limitations: Verify compatibility with exact model numbers since some variants may require slight dimensional confirmation.
What to watch for: The tread design favors gripping when traction is critical; on smooth surfaces, tread wear may be more apparent than on aggressive patterns.
Rubber Track 16″ 400 x 72.5 x 74 ME (Kubota U55-4)
Brand: National 1 Track & Parts
Size and fit: 400 x 72.5 x 74, listed as compatible with Kubota U55-4 and similar compact excavators in the 1–2 ton range. The ME designation indicates a specific cross-section within the 400 mm width family.
Why chosen: The ME variant is aimed at stability and even wear, making it a reliable substitute for replacement tracks on small Kubota models.
Limitations: Some Kubota variations outside the listed line may require additional tensioning adjustments.
What to watch for: Track tension and wheel alignment remain critical for longevity on small excavators with tight swing radii.
2 Pcs Excavator Rubber Track 180x72x37 (Mini Excavators)
Brand: BeiJiOuZhiZao
Size and fit: 180x72x37, widely used on 0.8–2T mini excavators. The two-track set is convenient for front or rear wheel replacement on small machines.
Why chosen: This option caters to the smaller end of the market, where 400 mm-wide tracks are not typical, but compatibility considerations and durability for the smallest machines make it relevant for comparison. It helps illustrate the breadth of track options available for smaller builds.
Limitations: Not a direct match for 400 mm width; verify wheel and undercarriage clearance before purchasing.
What to watch for: Ensure mounting hardware and carrier frame are compatible with the 180 mm width to avoid misfit on larger machines.
2pc Rubber Track 180x72x45 (Bobcat MT85 / MT100, Narrow)
Brand: Rio Rubber Track Inc
Size and fit: 180x72x45, narrow track format designed for Bobcat MT85/MT100 and similar compact models. The spec emphasizes steel-reinforced cores and modern tread patterns.
Why chosen: This set demonstrates the importance of core reinforcement and tread design for smaller machines that require robust, flexible tracks with reliable stability.
Caution: This option is not a direct match for 400 mm width; check wheel engagement and undercarriage clearance for non-typical Bobcat configurations.
What to watch for: Tight turning radii can influence wear; ensure compatible sprockets and idlers are used with this width.
Buying Guide
What size do I need?
Measure your machine’s track width, pitch, and overall cross-section. For 400×72 or 400×74 sizes, look for tracks described as 400x72x74 or 400x74x72. Cross-reference your model with the manufacturer’s recommendations to avoid misfits.
What tread design matters?
Solid tread patterns provide different traction on mud, gravel, and asphalt. For mixed environments, consider a tread that balances grip with tire-like wear resistance. V-tread or block patterns typically deliver strong traction in challenging terrain.
Material and durability considerations
High-quality rubber compounds and reinforced cores (steel cords or other reinforcements) extend life and absorb vibration. Direct steel-reinforced cores enhance durability for heavier loads, while premium rubber compounds resist wear on abrasive surfaces.
Compatibility and installation
Check compatibility with your machine’s model, year, and undercarriage configuration. Confirm mounting dimensions, sprocket compatibility, and tensioning requirements. Some tracks include user-friendly tensioning methods; others require professional installation.
Maintenance tips
- Regularly inspect undercarriage components for wear or damage.
- Ensure proper tension to prevent derailing or uneven wear.
- Clean tracks after use in dirt or mud to minimize abrasive wear.
- Store spares in a cool, dry place to preserve rubber integrity.
FAQ
- Q: Are 400×72 and 400×74 tracks interchangeable? A: They share similar cross-sections, but model-specific compatibility should be confirmed with the OEM or retailer.
- Q: What is the best track for rough terrain? A: Tracks with robust tread patterns and reinforced cores perform better on uneven surfaces and in mixed terrain.
- Q: How do I know if a 180x72x37 track fits my machine? A: This size is common for very small mini-excavators; verify the width, pitch, and wheel clearance against your equipment’s specifications.
- Q: Do tracks affect machine stability? A: Yes, track width and tread design influence stability, weight distribution, and traction on slopes and loose ground.
- Q: Can I replace only one side’s track? A: It’s generally recommended to replace tracks in matched pairs to maintain balance and traction.
- Q: Do tracks require special tools for installation? A: Some tracks need professional equipment; verify installation requirements with the track manufacturer or seller.
