Abstract
A method of using a grass trimming apparatus includes the steps of: providing a grass trimming apparatus, including a trimmer head assembly having a spinning support guide at a bottom portion thereof, and a cutting mechanism positioned above the spinning support guide; holding the grass trimming apparatus in an operable position; placing the spinning support guide on a trimmable surface, whereby the spinning support guide provides a point of contact between the grass trimming apparatus and the trimmable surface; activating the cutting mechanism; trimming the cutting surface to a desired height; and moving the grass trimming apparatus along the trimmable surface while maintaining the point of contact.

A method of using a grass trimming apparatus, the method comprising:
- (a) providing a grass trimming apparatus, the grass trimming apparatus including
- (i) a trimmer head assembly comprising a housing,
- (ii) a trimming line partially disposed within the housing, at least part of the trimming line extending external to the housing for effecting grass trimming when spun,
- (iii) a spinning support guide removably attached to an underside of the housing, the spinning support guide including
- (A) a base mount disc removably secured to the underside of the housing,
- (B) a thread receptacle disposed above the base mount disc,
- (C) one or more original spacer discs, and
- (D) a semispherical base,
- (E) wherein the base mount disc, the one or more original spacer discs, and the semispherical base are coupled together by a fast fastener passing through an opening in each of the base mount disc, the one or more original spacer discs, and the semispherical base, a portion of the faster proximate one of its ends being threadably received within a threaded receptacle;
- (b) holding the grass trimming apparatus in an operable position;
- (c) placing the spinning support guide on a trimmable surface, whereby the spinning support guide provides a point of contact between the grass trimming apparatus and the first trimmable surface;
- (d) effecting spinning of the trimming line;
- (e) trimming a portion of the first trimmable surface to the first height;
- (f) moving the grass trimming apparatus along the trimmable surface while maintaining the point of contact to effort trimming of an additional portion of the first trimmable surface to the first height;
- (g) removing the first fastener so as to decouple the semispherical base from the base mount disc and allow insertion or removal of spacer discs;
- (h) adding one or more additional spacer discs to the spinning support guide;
- and
- (i) inserting a second fastener so as to couple together the base mount disc, the one or more original spacer discs, the added one or more additional spacer discs, and the semispherical base;
- (j) holding the grass trimming apparatus in an operable position;
- (k) placing the spinning support guide on a second trimmable surface, whereby the spinning support guide provides a point of contact between the grass trimming apparatus and the second trimmable surface;
- (l) effecting spinning of the trimming line;
- (m) trimming a portion of the second trimmable surface to a second height;
- and
- (n) moving the grass trimming apparatus along the second trimmable surface while maintaining the point of contact to effect trimming of an additional portion of the second trimmable surface to the second height;
- (o) wherein the second height differs from the first height based on a height of the added one or more additional spacer discs.
