DIMENSIONS & TIRES
The Zetor 25A has a compact wheelbase of 74.8 inches, providing excellent maneuverability in tight spaces, making it ideal for small farming operations or landscaping tasks. With a weight of 4026 lbs, its stability on uneven terrain is an advantage; however, operators should be cautious of potential limited load capacity. The tire configuration—5.50-16 front and 11.25-24 rear—offers a balanced performance in traction but may pose challenges in muddy conditions where wider tires could provide better flotation.
