Tough, Reliable, Versatile, Accurate, and Fast. This is the reality of today's planter. The YP-4025 and 4025A fit this description to a "T"! 3-section flex, trapezoidal 3-bar frame gives this planter the weight and strength to excel in tough double crop. Couple this with (10) 15x16.5 skid steer tires or optional (10)15x19.5 skid steer tires and you have a planter that is equally at home in a soggy spring corn field.
