Product Description
Which Width Is Right for Your T650?
- Factory-installed width on most T650s
- Lower tension on rollers → longer undercarriage life
- Best for hard surfaces: concrete, asphalt, packed gravel
- Better maneuverability in tight spaces
- SKU: B320X86X52Z-BTT650
- Distributes T650's 9,113 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: B400X86X52Z-BTT650
- Width option: 450mm
- Fits Bobcat T650
- SKU: B450X86X52Z-BTT650
Not sure which to choose? Most T650s 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.
Z-Lug 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 Z-Lug is the maximum-traction pattern — built for operators working steep grades, snow, ice, or any conditions where grip is the top priority. The aggressive zigzag lug pattern digs in harder than C-Lug or Block, making it the right choice for earthmoving, grading on slopes, and winter work. Trades some pavement smoothness for significantly more bite. See all available patterns at the bottom of this page.
Know Your Machine: Bobcat T650 Undercarriage Facts
The T650 is a large-frame Bobcat CTL delivering 74 hp and 2,570 lbs rated operating capacity across three available track widths — 320mm (12.6"), 400mm (15.7"), and 450mm (17.7"). At 9,113 lbs with 5.7 psi on standard 320mm tracks, it's a serious production machine for earthmoving, loading, and site development. Wider tracks dramatically reduce ground pressure for demanding conditions. 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 |
| Z-Lug Tread | Aggressive zigzag pattern for maximum grip | Best traction in soft/loose conditions. Wears faster on pavement. |
| Lug Height | ~1" nominal new depth | Replace when worn below ⅓ remaining — traction loss accelerates past that point |
Is It Time to Replace Your T650'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 9,113 lbs operating weight the T650 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 | B320X86X52Z-BTT650 |
| 400mm Width (400×86×52) | 400mm (15.7") | 86mm | 52 | B400X86X52Z-BTT650 |
| 450mm Width (450×86×52) | 450mm (17.7") | 86mm | 52 | B450X86X52Z-BTT650 |
