Turf Tread — Is It Right for Your Work?
| Pattern | Best Used For |
|---|---|
| Bar | Flat terrain · large ground contact · stability on firm surfaces |
| Block | General purpose · hardpack · dirt · long pavement runs |
| C-Lug | Mixed terrain · grading · site work · on/off road · concrete & dirt |
| Q-Tread | Multi-directional traction · good all-around performance |
| Split Bar | Bidirectional traction · shock absorption · smooth ride on varied ground |
| Turf ✔ | Lawns · landscaping · minimal ground disturbance |
Non-marking white rubber also available. See non-marking options →
The Turf pattern is purpose-built for operators working on finished lawns, golf courses, sports fields, or any surface where ground disturbance must be minimized. The low-profile tread reduces turf tear during turns and leaves a lighter footprint than any lug or bar pattern. Not designed for aggressive digging or muddy conditions. See all available patterns at the bottom of this page.
Know Your Machine: Caterpillar 239D Undercarriage Facts
The 239D is a radial-lift Caterpillar compact track loader with a 2,050 lb rated operating capacity and 2 available track widths — 320mm (12.6") and 400mm (15.7"). At approximately 7,289 lbs operating weight, it delivers strong pushing and lifting performance for landscaping, site prep, grading, and utility work. The 320mm track is the factory-standard width; the wider 400mm option reduces ground pressure for operators working on soft or sensitive ground. 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 | Wear-resistant · premium bonding agent | Protects cords from moisture · bonds all layers · absorbs impact on hard surfaces |
| Turf Tread | Low-profile tread for minimal ground disturbance | Reduces turf damage. Lightest footprint of any pattern. |
| Lug Height | ~1" nominal new depth | Replace when worn below ⅓ remaining — traction loss accelerates past that point |
Is It Time to Replace Your 239D'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 7,289 lbs operating weight the 239D 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
