The safety specifications given in this standard are for powered (a) pedestrian-controlled machines, (b) ride-on machines and (c) implements for use with pedestrian and ride-on machines intended for marketing as commercial turf care equipment and that are customarily used by hired operators. Equipment covered may consist of two or more components that are functionally connected and may be produced by different manufacturers. Specific requirements are established in the standard for reel, rotary, and flail mowers as well as power rakes because of their prevalence, but this standard is intended to apply to all types of commercial turf care equipment. Each functional component shall conform to each section of this standard as it logically applies. Additionally, this standard applies to all aftermarket parts, attachments and accessories. Any manufacturer of aftermarket parts, attachments, implements, and accessories is responsible for ensuring compliance to this standard. Safety specifications in this standard apply only to a configuration of attachments, implements, and accessories approved by their respective manufacturers.
These specifications are not intended to apply to:
– turf care equipment that is designed primarily for personal use by a consumer in or around a permanent or temporary household or residence;
– equipment that is designed primarily for agricultural purposes; and
– equipment that is designed primarily for cutting grass and other growth on highways and is designed for operation with agricultural/industrial tractors.
The effective implementation date of this standard shall be two (2) years after the publication date and shall apply to all products built after that date. Manufacturers may also comply with the requirements of this standard anytime after the publication date.
