Product Description
Which Width Is Right for Your 279D?
- Factory-installed width on most 279Ds
- Lower tension on rollers → longer undercarriage life
- Best for hard surfaces: concrete, asphalt, packed gravel
- Better maneuverability in tight spaces
- SKU: B400X86X56T-CR279D
- Distributes 279D's 9,893 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: B450X86X56T-CR279D

Turf Tread — Is It Right for Your Work?
The Turf pattern is purpose-built for operators working on finished lawns, golf courses, sports fields, or any surface where ground disturbance must be minimized. The low-profile tread reduces turf tear during turns and leaves a lighter footprint than any lug or bar pattern. Not designed for aggressive digging or muddy conditions.
