Product Description
Which Width Is Right for Your T300?
- Factory-installed width on most T300s
- Lower tension on rollers → longer undercarriage life
- Best for hard surfaces: concrete, asphalt, packed gravel
- Better maneuverability in tight spaces
- SKU: B400X86X55Q-BTT300
- Distributes T300's 9,702 lbs weight over a larger footprint
- Reduces psi → less lawn & turf damage
- Ideal for soft/wet ground, mud, landscaping work
- Larger footprint absorbs more impact — softer ride on rough terrain
- SKU: B450X86X55Q-BTT300
Not sure which to choose? Most T300s leave the factory with 400mm tracks, but all widths install on the same undercarriage without modification. Or just call us at 800-966-6640 and tell us your machine — we'll match you in 30 seconds.
Q-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 |
| Z-Lug | Steep grades · snow · ice · maximum traction applications |
Non-marking white rubber also available. See non-marking options →
The Q-Tread pattern uses a diamond/quad-lug layout that provides traction in multiple directions simultaneously. This makes it a strong all-around performer on mixed surfaces — whether you're pushing material in tight quarters, grading uneven ground, or transitioning between soft and hard surfaces frequently during the workday. See all available patterns at the bottom of this page.
Know Your Machine: Bobcat T300 Undercarriage Facts
The T300 is a large-frame Bobcat CTL with a 3,000 lb rated operating capacity — one of the highest in the Bobcat lineup. Available in 400mm (15.7") or 450mm (17.7") track widths, the T300 starts at 4.2 psi ground pressure on the 450mm standard track. At 9,702 lbs, it's a serious production machine for earthmoving, loading, and demolition work. 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 |
| Q-Tread Pattern | Diamond/quad-lug layout for multi-directional grip | Traction in all directions. Better than bar or block in loose material. |
| Lug Height | ~1" nominal new depth | Replace when worn below ⅓ remaining — traction loss accelerates past that point |
Is It Time to Replace Your T300'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 9,702 lbs operating weight the T300 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 |
|---|---|---|---|---|
| 400mm Width (400×86×55) | 400mm (15.7") | 86mm | 55 | B400X86X55Q-BTT300 |
| 450mm Width (450×86×55) | 450mm (17.7") | 86mm | 55 | B450X86X55Q-BTT300 |
