Description
Our heavy-duty replacement Bobcat T66 compact track loader tracks are engineered specifically to handle the structural layout and high-torque weight distribution of this 8,840 lb. R-Series machine. As a heavy-duty vertical-lift model, the T66 is built for extended lift heights, high-capacity attachment work, and aggressive grading. To handle the shifting center of gravity and high stress generated during intensive material-handling cycles, our tracks are built from a premium natural rubber compound, internally reinforced with continuous, high-tensile steel cables and drop-forged iron links. This premium construction effectively converts the loader’s upgraded 74 HP engine output into stable pushing power while preventing rubber stretching and drive-lug tearing at the machine’s full 2,450 lb. rated operating capacity, protecting your undercarriage components on demanding commercial jobsites.

Bobcat T66 Skid Steer Tracks – Tread Options
Selecting the correct tread pattern configuration for your replacement Bobcat T66 rubber tracks depends entirely on your specific jobsite environment. Because this high-performance vertical-lift model exerts a substantial 7,000 lb. static tipping load, the undercarriage experiences highly concentrated directional stress when handling heavy material or running demanding hydraulic attachments. Use the terrain suitability table below to find the pattern that best meets your job’s requirements.
Tread Pattern | Best Jobsite Application | Hard Surface | Mud/Clay | Snow/Ice | Demolition | Forestry | Turf/ Soft Soil |
Block | Asphalt, Concrete, Pavers | ||||||
C Block | All-around use, General Offroad use | ||||||
Zig Zag Bar | Snow, Ice, Mud, Steep Grades | ||||||
Multi-Bar | Forestry, Loose soil, Turf, |
Undercarriage Inspection & Parts
Installing brand-new rubber tracks onto worn sprockets or out-of-spec rollers is the leading cause of premature track failure. Given the increased horsepower and operating weight of this heavy-duty frame, worn drive components will rapidly degrade the internal rubber guides of your fresh tracks. Before you install a new set of tracks on your machine, inspect your wear components to safeguard your investment. Our exact-fit parts for Bobcat T66 loaders include:
- View Drive Sprockets for Bobcat T66 – New sprockets ensure perfect tooth engagement and prevent hooked teeth from chewing up your new rubber drive lugs.
- View Bottom Rollers for Bobcat T66 – Heavy-duty rollers evenly distribute the machine’s 8,840 lb. operating weight across the track frame to prevent rail binding.
- View Front & Rear Idlers for Bobcat T66 – Engineered to maintain straight track alignment and correct pathing, preventing costly derailments during high-climb or heavy loading maneuvers.

Rubber Track Maintenance
- Maintain Correct Tension: Never “eyeball” your track sag. Over-tightening robs horsepower, strains drive bearings, and can snap internal steel cables. Under-tightening causes detracking, which instantly destroys the track’s internal drive lugs. Check your operator’s manual for exact sag tolerances.
- Daily End-of-Shift Cleanouts: Use a spade or pressure washer to clear mud, clay, and gravel from the undercarriage frames daily. Packed debris hardens overnight, acting like heavy-grit sandpaper that grinds down rubberized surfaces and seizes bottom rollers.
- Inspect Sprockets & Rollers: Never install a brand-new rubber track on a worn-out undercarriage. Sharp or “shark-toothed” sprockets will actively gouge and tear out your new track’s drive lugs. Ensure bottom rollers spin freely and check idlers for rough rims or bad bearings.
- Practice Smart Operating Habits: Avoid high-speed, 90-degree pivot turns on concrete or asphalt to prevent severe tread scalloping (especially if not using a block tread). Always approach curbs straight-on (perpendicularly) and travel straight up or down grades—never sideways—to prevent edge slicing and derailment.
