TIRES
The John Deere 8RX 310's turning radius of 9.14 m (30 ft) at a 3048-mm (120-in.) tread setting is beneficial for maneuverability in tight spaces, such as vegetable or specialty crop fields. However, the wide track configuration may limit agility compared to narrower models, especially in constrained environments. Operators should consider this trade-off when planning tasks that require frequent direction changes or navigate narrow paths.
