GB 26508-2011 is a current mandatory Chinese national standard for Garden machinery - Ride-on machines with lawn mowers - Safety requirements and testing. It appears in the Food compliance cluster with a product safety focus and has an implementation date of Apr 1, 2012.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard is mandatory and applies to ride-on rotary lawnmowers powered by gasoline or diesel engines, where the operator controls the direction of travel via a steering wheel or control levers. It is primarily designed for machines used in lawn maintenance and gardening. It does not apply to walk-behind mowers or pedestrian-controlled machines, which are covered by separate standards. Other internal combustion engine-driven ride-on mowers may refer to this standard for relevant sections.
Technical requirements
The standard specifies comprehensive safety and design requirements to mitigate risks during operation, maintenance, and transportation. A key focus is on structural integrity and operator protection. It mandates specific designs for the cutting means enclosure (deck) to prevent foot access and object projection. Manufacturers must ensure that the discharge opening and other deck openings do not allow debris to reach the operator's zone.\n\nThe standard details requirements for control mechanisms, including engine switches, speed control, and braking systems. It mandates the presence of operator presence controls (OPC) and interlock systems to prevent accidental movement or blade engagement when the operator leaves the seat. Specific requirements for service and parking brake performance are established to ensure safe stopping and parking on inclines.\n\nFurthermore, the standard addresses stability and Roll-Over Protective Structures (ROPS). It sets static and dynamic stability test parameters to prevent tip-overs on slopes. Machines exceeding a specific mass threshold must be equipped with ROPS that comply with referenced national standards.\n\nAdditional requirements cover electrical safety, vibration, and noise limits. It specifies maximum A-weighted sound power levels based on the cutting width. Thermal protection requirements are also included to prevent burns from hot engine surfaces, and guards must be in place for power transmission components.
Testing methods
The standard outlines several critical testing procedures to verify compliance. Stability tests include both static tilt tests (longitudinal and lateral) and dynamic tests (steering and unexpected drive engagement) to measure wheel lift angles. Brake performance tests measure stopping distances from maximum speed and verify the holding capability of parking brakes on a 16.7° slope. Structural integrity tests evaluate the cutting deck, guards, and grass catchers against projectile impacts. Object projection tests use a target board arrangement to ensure debris is not thrown into the operator or bystander zones. Additionally, the standard references specific appendices for measuring hand-arm and whole-body vibration, as well as noise emission using engineering methods (Grade 2 accuracy).
FAQs
What products are regulated under GB 26508-2011?
GB 26508-2011 regulates ride-on rotary lawnmowers powered by gasoline or diesel engines, where the operator sits on the machine and controls the direction of travel using a steering wheel or control levers.
Is GB 26508-2011 a mandatory standard?
Yes, all technical content in GB 26508-2011 is mandatory. Manufacturers must comply with these safety requirements and testing methods to sell ride-on lawnmowers in the Chinese market.
Does GB 26508-2011 require a Roll-Over Protective Structure (ROPS)?
ROPS is required if the total mass of the machine, complete mowing attachment, full fuel tank, and manufacturer-recommended ballast exceeds 565 kg. If the mass is below this threshold, a ROPS is not required.
