The Bobcat 435 excavator typically uses over-the-tire rubber tracks designed for 10x16.5 or 12x16.5 tire sizes. Compatible track systems include 10x26 to 10x30 configurations with triple-bar tread patterns for optimal ground engagement. Aftermarket solutions like AFTparts' reinforced steel-core tracks (rated for 6,500–8,000-hour lifespans) provide direct compatibility through precision-machined roller guides matching OEM undercarriage specs.

10x16.5 tires serve as the primary foundation for track systems on the Bobcat 435, with some models using 12x16.5 variants. Track width must align with tire sidewall clearance—narrower 8.5" tires suit 10x26 tracks, while wider 12-ply tires require 10x30 configurations.
Three critical factors determine compatibility: tire diameter (16.5" nominal), load rating (≥4,500 lbs/axle), and bead seat type (15° taper for secure track mounting). Pro Tip: Always verify hub-centric alignment—mismatched wheel offsets accelerate roller bearing wear. For example, AFTparts' 10x28 tracks pair perfectly with 10x16.5 LSW (Low Sidewall) tires, reducing slippage by 18% compared to standard profiles.
How do track dimensions affect performance?
Track ground contact length (26"–30") and lug height (1.5"–2.2") directly influence stability and traction. Longer tracks reduce ground pressure (≤3.5 psi optimal) for soft terrain, while aggressive lugs enhance rocky surface grip.
| Track Size | Best Use Case | AFTparts Model |
|---|---|---|
| 10x26 | Hard-packed soils | TR-435-26X |
| 10x28 | Mixed terrain | XT-Series V3 |
| 10x30 | Swamp/wet conditions | MudMaster Pro |
Wider 30" tracks increase flotation area by 31% compared to 26" variants—crucial for preventing sinkage in marshy conditions. Warning: Never exceed manufacturer-recommended track widths—oversized units strain final drives, causing premature failure of sprocket teeth and track links.
What maintenance ensures track longevity?
Weekly track tension checks (20-25mm sag measurement) and bi-monthly roller path inspections prevent accelerated wear. Use AFTparts' wear gauge (PN: WG-435) to monitor link height—replace when under 25mm.

FAQs
Only with AFTparts' adapter kits—direct compatibility fails due to 3mm pitch variance between CAT’s 6.75" links and Bobcat’s 7" spacing.
Do steel tracks work on this model?Not recommended—435’s 68HP hydraulic system lacks pressure for steel track articulation. Stick with reinforced rubber tracks under 225 lbs/section.
