Non-Marking L Lug Tread — Is It Right for Your Work?
| Pattern | Best Used For |
|---|---|
| S Bar | Firm ground · general purpose · smooth surfaces · packed gravel |
| T Lug | Mixed terrain · compact machine applications · on/off road · versatile grip |
| L Lug | Mixed terrain · compact machines · aggressive grip · soft ground |
| C-Lug | Mixed terrain · grading · site work · on/off road · concrete & dirt |
| Turf | Lawns · landscaping · minimal ground disturbance |
Standard black rubber versions also available. See standard patterns →
The Non-Marking L Lug uses white rubber compound that won't leave black marks on finished surfaces, paired with the aggressive L Lug tread geometry for strong grip. You get the bite and self-cleaning action of the standard L Lug in a non-marking compound — ideal for indoor construction, renovations, and any jobsite where surface marking is not acceptable. See all available patterns at the bottom of this page.
Know Your Machine: Bobcat MT85 Undercarriage Facts
The MT85 is Bobcat's mid-size mini track loader — 35% more rated operating capacity than the MT55 at 850 lbs, while still fitting under 36 inches wide with narrow tracks. The optional 230mm wide track drops ground pressure to 3.5 psi, making it a strong turf and landscaping machine. At 3,103 lbs, it's the most capable stand-on mini track loader in the Bobcat lineup. Here's what that means for your track purchase:
What's Inside the Track
| Component | Specification | Why It Matters |
|---|---|---|
| Iron Cores | Drop-forged steel embeds · pitch-spaced | Maintain track shape · resist deformation under load · engage sprocket cleanly |
| Steel Cords | Acid-washed · continuous cord layer | Carry tensile load · prevent stretching · hold pitch dimension over time |
| Rubber Compound | Non-marking white rubber · premium compound | Won't leave black marks on finished surfaces · same durability as standard |
| Non-Marking L Lug Tread | White rubber compound leaves no black marks | Same L Lug geometry as standard. Premium compound for sensitive surfaces. |
| Lug Height | ~1" nominal new depth | Replace when worn below ⅓ remaining — traction loss accelerates past that point |
Is It Time to Replace Your MT85's Tracks?
| What You're Seeing | What It Means | Action |
|---|---|---|
| Exposed steel cords | Carcass worn through — moisture will corrode cords | Replace immediately |
| Flat or missing lugs | Tread depth below ⅓ of original 1" — traction loss | Plan replacement soon |
| Track won't hold tension | Carcass has stretched beyond adjuster range | Replace track · inspect adjuster |
| Cracks around guide bars | Aging rubber · UV damage · abrasive turning | Monitor closely, plan replacement |
| Track jumping off | Tension too loose OR guide bar/idler damage | Check tension first · inspect guide bars |
At 3,103 lbs operating weight the MT85 accelerates track wear faster than lighter machines. On abrasive surfaces (concrete, asphalt), expect 1,200–1,500 hours from quality replacement tracks. Soft-ground or dirt-only work can extend this considerably.
Track Dimensions
| Size | Width | Pitch | Links | SKU |
