1. A powered turf conditioning brush comprising:

  • a generally cylindrical brush base configured to be powered by and mounted within a groomer drive accessory of a reel mower cutting unit, where the reel mower cutting unit comprises a front roller, a rear roller, a cutting reel, a bedknife and a groomer drive accessory where the groomer drive accessory resides between the front roller and the cutting reel, said generally cylindrical brush base having a predetermined base radius and a predetermined base width;

    a plurality of bristle tufts mounted radially in a predetermined number of parallel rows along the width of said generally cylindrical brush base, said predetermined number of parallel rows being no less than 8 and no greater than 16;

    whereby when powered by the groomer drive accessory, the bristle tufts of the brush contacts the turf in an orientation that creates a substantially uniform vertical lifting of the turf in order to more effectively facilitate cutting by the cutting reel;

    each bristle tufts comprising a plurality of bristles, each of said bristles having a predetermined bristle length and predetermined bristle diameter, whereby said bristle length and bristle diameter contribute to the relative stiffness of the bristle tufts and each of said plurality of bristle tufts configured to be spaced equally apart from adjacent bristle tufts in its own row by a predetermined tuft spacing value and configured to be offset from bristle tufts in adjacent rows by a predetermined tuft offset value, said tuft offset value being the ratio of said predetermined tuft spacing value divided by an offset factor, the offset factor being an integer no less than 2 and no greater than 4;

    whereby the turf spacing value and turf offset value facilitate bristle penetration into the turf by optimizing the frequency of contact between the bristle tufts and the turf.
