Description

CROSS REFERENCE TO RELATED APPLICATIONS This application claims the benefit of the filing date of U.S. Provisional Patent Application 63/396,513 entitled “Brush Attachment System for a Turfgrass Mower” to Harold F. Howard that was filed on Aug. 9, 2022, the disclosure of which is hereby incorporated herein by this reference. TECHNICAL FIELD Aspects of this document relate generally to turfgrass mowers, and more specifically to brush attachments for turfgrass mowers. BACKGROUND In caring for turfgrass, it is desirable to have each blade of grass be as close to the same length as possible, as this increases the aesthetic appeal of the grass and allows the grass to apply a consistent effect to any objects traveling over the grass, such as a golf ball. To this end, turfgrass may be brushed prior to cutting so that each blade will be as close to the same length as possible. SUMMARY Aspects of this document relate to a brush attachment system for a turfgrass mower, comprising a left-side module and a right-side module configured to respectively couple with a left side and a right side of the turfgrass mower, each of the left-side module and the right-side module having a mounting bracket configured to mount onto the turfgrass mower, the mounting bracket having a mounting aperture surrounded by a recessed cavity sized and shaped to receive a portion of the turfgrass mower, an adaptor extending through the mounting aperture of the mounting bracket and having a lip sized and shaped to prevent the adaptor from passing completely through the mounting aperture, the adaptor configured to secure the mounting bracket in a mounted position where the portion of the turfgrass mower is within the cavity, an arm support coupled to the mounting bracket and rotationally fixed with respect to the mounting bracket, the arm support having a main body with an upper stop and a lower stop extending away from the main body, and an arm having a first end pivotally coupled to the arm support and a second end configured to couple with a turfgrass brush, wherein the upper stop and the lower stop are each positioned to limit rotation of the arm with respect to the arm support and wherein the arm is configured to rotate between an active position in which the arm is adjacent the lower stop and an inactive position in which the arm is adjacent the upper stop, and an elongated member configured to extend through the turfgrass mower, attach the adaptor of the left-side module to the adaptor of the right-side module, and exert a first force on the adaptor of the left-side module toward the turfgrass mower and a second force on the adaptor of the right-side module toward the turfgrass mower, wherein the mounting bracket is configured to be rotationally fixed in all directions with respect to the turfgrass mower when the mounting bracket is mounted onto the turfgrass mower, and wherein when the brush attachment system is mounted on the turfgrass mower and the arms of the left-side module and the right-side module are coupled to the turfgrass brush in the active position, the turfgrass brush is positioned in front of the turfgrass mower and when the brush attachment system is mounted on the turfgrass mower and the arms of the left-side module and the right-side module are coupled to the turfgrass brush in the inactive position, the turfgrass brush is positioned above the turfgrass mower. Particular embodiments may comprise one or more of the following features. The arm support may have a retaining bar pivotally coupled to the main body adjacent the upper stop, wherein the retaining bar is configured to rotate into a retaining position in which the retaining bar intersects with a plane of rotation of the arm and wherein, when the arm is in the inactive position and the retaining bar is rotated to the retaining position, the retaining bar locks the arm in the inactive position until the retaining bar is rotated out of the retaining position. The main body of the arm support may have a ledge configured to support the retaining bar in the retaining position. The position of the lower stop on the main body of the arm support may be adjustable. The main body of the arm support may have a plurality of holes, wherein each hole of the plurality of holes is configured to couple with the lower stop.
