DAVID BROWN 1200 TIRES
The David Brown 1200 tractor features standard agricultural tires which can influence traction and stability based on the 2WD or 4WD configuration; 2WD with 7.50-16 front and 13.6-38 rear tires offers higher speed on flat terrain, while the 4WD variant with 10-24 front and 13.6-36 rear tires enhances grip and maneuverability in challenging conditions. Key advantages of the 4WD system include improved performance in wet or uneven fields, although it may incur higher operational costs and maintenance complexity. Scenario: Opt for the 4WD option if frequently operating in diverse, rugged landscapes to maximize efficiency and minimize soil compaction.
