Product Description
Which Width Is Right for Your T630?
- Factory-installed width on most T630s
- Lower tension on rollers → longer undercarriage life
- Best for hard surfaces: concrete, asphalt, packed gravel
- Better maneuverability in tight spaces
- SKU: B320x86x52Q-BTT630
- Distributes T630's 9,015 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: B400x86x52Q-BTT630
Not sure which to choose? Most T630s leave the factory with 320mm 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 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 provides multi-directional traction — gripping equally well during turns, side-slopes, and straight-line travel. For operators working on varied terrain where the machine is constantly changing direction, the Q-Tread delivers consistent grip without aggressive wear.

Know Your Machine: Bobcat T630 Undercarriage Facts
The T630 is a large-frame Bobcat CTL with a 2,230 lb rated operating capacity and three available track widths — 320mm (12.6"), 400mm (15.7"), and 450mm (17.7"). At 9,015 lbs with 5.3 psi ground pressure on standard 320mm tracks, it delivers serious lifting and site-work performance. The wider track options significantly reduce ground pressure for soft-ground and turf applications. 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 Tread | Multi-directional tread design | Consistent grip in turns and side-slopes. Good all-around wear characteristics. |
| Lug Height | ~1" nominal new depth | Replace when worn below ⅓ remaining — traction loss accelerates past that point |
Is It Time to Replace Your T630'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 9,015 lbs operating weight the T630 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 |
|---|---|---|---|---|
| 320mm Width (320×86×52) | 320mm (12.6") | 86mm | 52 | B320x86x52Q-BTT630 |
| 400mm Width (400×86×52) | 400mm (15.7") | 86mm | 52 | B400x86x52Q-BTT630 |
