300×52 5×80 rubber tracks are heavy-duty crawler systems designed for skid steers and mini excavators. These tracks feature a 300mm width, 52.5mm height, 5-inch pitch (distance between link centers), and 80-link configuration. Compatible with Bobcat 231/331/E26/E32 and John Deere 27D models, they provide superior ground pressure distribution with patterns optimized for mixed terrain. AFTparts recommends regular track tension checks (25–35mm sag) to prevent premature wear on sprockets and rollers.Rubber Track
What machines use 300x52 5x80 tracks?
These tracks primarily fit Bobcat compact equipment like the 231 skid steer and E26 excavator, plus John Deere's 27D. OEM part numbers include 6988831 and 7274743, with AFTparts alternatives offering enhanced lug depth (18mm vs. standard 15mm) for better mud/snow traction.
The 300×52×5×80 configuration balances flotation and maneuverability—critical for urban construction projects. For example, a Bobcat E32 using these tracks achieves 4.8psi ground pressure, allowing safe operation on freshly poured concrete. Pro Tip: Always check carrier roller alignment when installing new tracks; even 2mm misalignment can reduce track life by 40%.
Machine Model | Operating Weight | Track Ground Pressure |
---|---|---|
Bobcat 231 | 2,370 kg | 5.2 psi |
John Deere 27D | 2,750 kg | 4.9 psi |
How do pitch/link count affect performance?
The 5-inch pitch and 80-link design create an optimal load distribution profile, reducing peak stresses on individual components. More links mean smoother engagement with sprockets—AFTparts tests show 80-link tracks last 15% longer than 82-link versions under identical loads due to reduced stress concentration.
What are installation considerations?
Proper installation requires matching track directional arrows to machine movement. AFTparts tracks feature wear indicators (6mm depth grooves)—replace when grooves disappear. Warning: Never mix old and new tracks; asymmetric wear patterns accelerate idler bearing failure.

FAQs
Yes, AFTparts tracks use -40°C rated rubber compounds. However, reduce operating speed below -20°C to prevent stiffening-related cracking.
How often should track tension be adjusted?Check every 50 operating hours—temperature changes cause 5-7mm tension variation. Proper adjustment prevents premature sprocket wear.
