An improved furrow closing mechanism for a seed planting apparatus including an apparatus for adjusting the distance between furrow closing wheels to correspond to adjustments in the size of the furrow being formed. The wheels are mounted on an axle assembly and this axle assembly includes an axle shaft having reduced first and second portions on each end thereof. A bearing is disposed on the outermost reduced section of each end of the axle shaft and a seal is disposed on an inner adjacent reduced section of each of the ends of such axle shaft. Adjustments to the distance between the soil contacting portions of the closing wheels are made by utilizing spacers corresponding to the distance for which it is desired to space the wheels outwardly from the position they would be in if no spacers were used.
