contractor shall be responsible for mowing turf infields and other designated ball diamond turf areas. (see Attachment l). (2) The Contractor shall maintain mowers that provide a smooth, even cut without ridges or depressions and without tearing of the leaf blades (caused by unsharpened mower blades). Mowing shall be performed at the speed the mowers manufacturer specifies to maximize quality of cut. Mowing shall be performed with straight and flowing patterns approved by the Director's Representative. The emphasis will be on quality mowing vs. speed and unprofessional patterns. From time to time the Director will direct the Contractor to change mowing pattern to minimize rutting and compaction.

If chemical detailing is performed, the Contractor shall use the string trimmer to remove the treated turf within one (1) week after symptoms of phytotoxicity become recognizable.

The Director's Representative may require the Contractor to use string lines to edge straight lines if the Contractor's staff fails to achieve this quality without this method. (2) The Contractor shall detail around trees, along walls/fences and other park amenities first using a sharpened shovel cut to establish a concentric round circle around trees, poles, etc. Once the initial detailed circle is established a string trimmer may be used to maintain the circle. Should the circle begin to deform the Director shall direct the Contractor to repeat the detail process. (3) The Contractor shall detail turf not greater than 10" away from walls or fences. Detail lines shall be made straight and shall be maintained straight.
