1 Scope

This part of GB/T 38364 specifies the rotary blade lawn mower and hob lawn mower powered by an internal combustion engine (the following simplified

(Referred to as "turf machine") terms and general test methods for safety requirements, including stepping (with or without passenger accessories) and riding type, and

And is equipped with.

--- metal cutting devices, and/or;

--- Non-metal cutting device, one or more cutting parts are hingedly mounted on a nearly circular driving device.

Cutting is achieved by centrifugal force, and the cutting energy (kinetic energy) of each cutting part is not less than 10J.

This section does not apply to.

--- Robot and remote-control lawn mower, flutter (flail) lawn mower, lawn mower, blade reciprocating lawn mower, trailing/half

Mounted lawn mowers and de-irrigators;

--- Cutting device components used with agricultural tractors;

--- Electric lawn mowers and lawn mowers powered by batteries.

Note. GB 4706.1-2005 and GB/T 4706.78-2005 give requirements for electric lawn mowers with walk control.

This section does not apply to lawn mowers produced before the release of this section.
