Abstract
A furrow closing apparatus is used with a planter that opens a furrow and deposits seeds as the planter moves in a forward direction over the ground. The furrow closing apparatus includes a frame attached to the planter and first and second closing wheels rotatably mounted on respective first and second closing wheel axles. A pivot axle extends from the frame generally transverse to the direction of travel of the planter and an equalizer bracket pivotably connected to the pivot axle. The equalizer bracket receives the first closing wheel axle in a position aft of the pivot axle and receives the second closing wheel axle in a position forward of the pivot axle such that the equalizer bracket pivots as the closing wheels traverse uneven ground to cause the first closing wheel and the second closing wheel to apply a substantially equal force in closing the furrow.
