Abstract: A template for properly determining the positions for the yardline numbers of an American-style football field includes a generally rectangular frame having an external perimeter and an internal opening defined by an internal perimeter. The shape of the internal opening, and the corresponding shape of the internal perimeter, is such that for each of the yardline numbers, i.e. 5, 4, 3, 2, 1, and 0, the internal perimeter defines a plurality of locations for abutting a corresponding plurality of outer edge portions of the yardline number. With the external perimeter appropriately aligned along one or more lines of the field, the frame can be used to properly locate any one of the six yardline numbers that are needed to properly locate all of the yardline numbers on an American-style football field. This frame reduces the number of templates needed to locate the yardline numbers of a football field, and also simplifies the process of properly locating the yardline numbers.

Abstract: An apparatus for extracting and collecting particulate infill from an infilled artificial turf field. A vehicle has a first forward end and a second rearward end. An infill extractor is located at the first end of the vehicle and adapted to extract infill from a strip of infilled athletic turf. Extracted infill falls into a bottom section of the infill extractor. An infill mover is secured to the vehicle and adapted to move the extracted infill from the bottom section of the infill extractor toward the second end of the vehicle. An infill collector is connected to the second end of the vehicle and operable to cooperate with the infill mover to collect the moved infill. The infill collector includes a frame that is laterally movable relative to the vehicle from an operative “in use” position to a stowed position.

Abstract: A subsurface warming system for an athletic field supplies positive pressurization to a particulate subsurface via a piping network with pipes that have openings. The system enables control of the temperature of the supplied air by varying the flow resistance at an output end of a constant air supply source, such as a positive displacement blower. By increasing the flow resistance at the output end of the blower, with a variably controllable valve equipped with a modulating actuator, the operating temperature of the blower increases and thereby causes a corresponding increase in the temperature of the air supplied therefrom. By varying the flow resistance, as needed, a user can vary the temperature of the air supplied to the piping network and eventually to the subsurface, to allow the problem associated with freezing of the subsurface during the winter season, for an athletic field that may be an artificial turf.
