Case 420CT Heavy-Duty Rubber Tracks | 320x86x50
Heavy-duty 320x86x50 replacement rubber tracks for the Case 420CT Compact Track Loader, built for dependable traction, stable ground contact, and productive operation across grading, loading, pushing, cleanup, and earthmoving work.
Ground Contact, Flotation & Control
The 320 mm track footprint supports stable operation over uneven ground. CASE emphasizes the tracked platform for lower ground pressure and consistent ground contact; tread pattern then becomes the main choice affecting bite, cleanout, ride quality, surface disturbance, and wear.
Choose the Tread for the Work
- C-Block: Broad block contact provides stable all-around traction and predictable steering across dirt, gravel, hardpack, rock, concrete, and general construction.
- Multi-Bar: A high-contact bar layout supports smooth travel, consistent traction, and reduced vibration across dirt, sand, packed ground, wet conditions, and hard flat surfaces.
- Zig-Zag: Stepped, angled lugs create multiple biting edges and open cleanout channels for mud, wet clay, snow, loose soil, and slopes.
- X-Terrain: Open, aggressive lug geometry prioritizes ground engagement and cleanout in loose, uneven, and severe off-road terrain.
- All-Terrain: A versatile mixed-surface tread balancing traction, stability, ride quality, and wear across changing jobsite conditions.
- Z-Max: High-bite lug geometry is built for demanding pushing and off-road work where strong ground engagement matters most.
- Block: Alternating blocks balance traction, machine stability, and ride quality across mixed dirt, gravel, and hardpack.
Heavy-Duty Track Construction
Advanced abrasion-resistant rubber, a continuous steel-cord core, and drop-forged, heat-treated steel links provide strength under repeated pushing, turning, grading, loading, and travel. Heavy-duty construction uses approximately 30% more rubber than standard-duty replacements through high-wear areas to help resist stretching, cuts, tearing, chunking, and premature abrasion.
Undercarriage & Track Life
Inspect sprockets, rollers, idlers, alignment, and track tension before installation. Worn components, debris packing, or incorrect tension can accelerate wear and reduce service life. Set final track tension to CASE service specifications after installation.
Warranty & Support
Nationwide fulfillment is available, backed by a 24-month warranty against manufacturing defects and application support when needed.

ENGINEERED FOR THE JOBSITE
Built Tough
Heavy-duty replacement rubber tracks engineered for compact track loaders, tracked skid steers, mini excavators, mini track loaders, and demanding construction equipment applications.
-
100% Virgin Rubber
Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.
-
Continuous Steel Cords
Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.
-
Drop-Forged Links
Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.
-
Corrosion Resistant
The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.
-
Reinforced Sidewalls
Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.
-
Low-Vibration Tread
Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.
