1. A trench closing system for a row unit of an agricultural planter, the row unit having a row unit frame supporting an opener disk for opening a seed trench in a soil surface as the row unit travels in a forward direction of travel, the trench closing system comprising:
a main frame supported by and extending rearwardly from the row unit frame;
a frame member pivotally supported from the main frame;
a pair of closing wheels each rotatably supported by the frame member with a first one of the pair of closing wheels disposed on a first side of the seed trench and a second one of the pair of closing wheels disposed on a second side of the seed trench, the pair of closing wheels cooperating with one another to close the opened seed trench with soil as the row unit travels in the forward direction of travel;
a first closing wheel soil deflector connected to an axle of the first closing wheel and extending opposite to the forward direction of travel beside the first closing wheel, wherein the soil deflector has a structure to keep soil from spraying as the trench closing system traverses the field;
wherein the first closing wheel soil deflector extends a distance beyond a diameter of the first closing wheel and extends toward the frame member behind the first closing wheel.
