1 Scope

This standard specifies the design and structural security of power-driven aggregate systems used in agriculture, horticulture, and site maintenance (such as landscaping).

Full requirements and their inspection methods. This standard applies to suspended, semi-suspended and traction machinery produced after its promulgation and implementation.

This standard provides methods for eliminating or reducing mechanical hazards when using aggregate systems for their intended purpose.

This standard does not address environmental hazards, road safety, electromagnetic compatibility, power output devices (PTO), PTO drive shaft protection and control requirements begging.

This standard does not apply to GB/T XXXX.2 (Safety requirements for lawnmowers powered by internal combustion engines for garden machinery. Part 2. Stepping Lawn mowers) and GB/T XXXX.3 (safety requirements of lawn machinery for garden machinery powered by internal combustion engines-Part 3. Mounted Machinery specified in lawn mowers).
