Rotating brush optimizing method

A method of fabricating an assembly for adjusting the spacing of a cylindrical brush coupled to a surface maintenance vehicle relative to a work surface, comprising the steps of:

• applying a first set of measurement indicia adjacent an edge portion of a frame member wherein the first set of measurement indicia relate to a length parameter of a majority of bristles of a cylindrical brush rotatably supported by the frame member;
• coupling a first side of the frame member to a surface maintenance vehicle;
• coupling a first end of a cable member to the frame member;
• coupling a second end of the cable member to a first end of a pivoting member;
• coupling a second end of the pivoting member to an actuator having a lever arm, where the actuator is coupled to pivot location of the surface maintenance vehicle, wherein said pivot location is spaced from the first end;
• and
• applying a second set of measurement indicia proximate said lever arm, wherein said second set of measurement indicia relate a position of the lever arm for adjusting the elevation of the frame member according to the length parameter of the majority of the bristles of the cylindrical brush.

An apparatus for rapidly and accurately adjusting the spacing of a horizontally disposed, moveable member coupled to a surface maintenance vehicle, wherein the moveable member has a working edge portion that is subject to wear which reduces the effective length of the working edge portion, said apparatus comprising:

• a horizontally disposed member having a working edge portion that is subject to wear, which wear reduces the effective length of the working edge portion;
• a first indicia to facilitate visually observing the effective length of the working edge portion and discerning the effective length;
• an adjusting device for moveably connecting the member to a surface maintenance vehicle so the member can be moved toward and away from a work surface;
• and
• a second indicia, related to the first indicia, near the adjusting device to facilitate adjusting the elevation of the member based on the effective length.
