`American
`National
`Standard
`
`Approval of an American National Standard requires review by ANSI that the
`requirements for due process, consensus, and other criteria for approval have
`been met by the standards developer.
`Consensus is established when, in the judgement of the ANSI Board of
`Standards Review, substantial agreement has been reached by directly and
`materially affected interests. Substantial agreement means much more than
`a simple majority, but not necessarily unanimity. Consensus requires that all
`views and objections be considered, and that a concerted effort be made
`towards their resolution.
`The use of American National Standards is completely voluntary; their
`existence does not in any respect preclude anyone, whether he has approved
`the standards or not, from manufacturing, marketing, purchasing, or using
`products, processes, or procedures not conforming to the standards.
`The American National Standards Institute does not develop standards and
`will in no circumstances give an interpretation of any American National
`Standard. Moreover, no person shall have the right or authority to issue an
`interpretation of an American National Standard in the name of the American
`National Standards
`Institute. Requests
`for
`interpretations should be
`addressed to the secretariat or sponsor whose name appears on the title
`page of this standard.
`CAUTION NOTICE: This American National Standard may be revised or
`withdrawn at any time. The procedures of the American National Standards
`Institute require that action be taken periodically to reaffirm, revise, or
`withdraw this standard. Purchasers of American National Standards may
`receive current information on all standards by calling or writing the American
`National Standards Institute.

`F o r e w o r d (This foreword is not part of American National Standard ANSI/OPEI B71.1-2012.)
`
`This standard is a revision of American National Standard for Consumer Turf Care
`Equipment - Walk-Behind Mowers and Ride-On Machines with Mowers - Safety
`Specifications, ANSI B71.1-2003. The first edition of this standard was approved and
`published by the American National Standards Institute in 1960. It has been revised
`thirteen times since initial publication, including this revision.
`The present revision was prepared by the Outdoor Power Equipment Institute's
`(OPEI) Lawn Mower Committee, as part of OPEI's continuing work on standards.
`The effective implementation date of this standard shall be two (2) years after the ap­
`proval date and shall apply to all products built after that date. Manufacturers may
`also certify to this standard anytime after the approval date.
`A summary of the principal changes included in this revision follows:
`- Hot surface requirements revised to use ISO cones;
`- Revised on-product safety messages to the most critical message;
`- Added requirements for large pedestrian-controlled machines;
`- Revised guarding requirements for operator location and rotating engine
`screens;
`- Broadened scope of ROPS requirements for ride-on machines;
`- Added requirements for lever-steer park brake and non-powered foot
`attachment lift;
`- Changed lateral stability test to last uphill tire for lift-off;
`- Added allowance for machine stability with positive upstop;
`- Exempted lever-steer machines from dynamic stability requirement;
`- Revised run-in time for blade stop test;
`- Added insertion force for foot probe test;
`- Eliminated single-color molded-in safety warning on discharge chute;
`- Harmonized figures with ANSI B71.4;
`- Made numerous editorial and text clarifications and updated references.
`Consensus for this standard was achieved by use of the Canvass Method. This stan­
`dard contains annexes that are all informative and are not considered requirements
`of this standard.
`Suggestions for improvement of the standard are welcome. They should be sent to
`the Outdoor Power Equipment Institute, 341 South Patrick Street, Alexandria, VA
`22314, or www.opei.org

`AMERICAN NATIONAL STANDARD
`
`ANSI/OPEI B71.1-2012
`
`American National Standard
`for Consumer Turf Care Equipment -
`Pedestrian-Controlled Mowers
`and Ride-On Mowers -
`Safety Specifications
`Part I:
`General
`
`1
`
`Scope
`
`The safety specifications given in this standard are for powered
`(a) reel and rotary pedestrian-controlled lawn mowers,
`(b) reel and rotary ride-on lawn mowers,
`(c) ride-on lawn tractors with mower attachments,
`(d) ride-on lawn and garden tractors with mower attachments, and
`(e) lever-steer and zero-turn ride-on mowers.
`These specifications are intended to provide safety requirements and to help ensure uniform operator
`environments. They are intended to apply to products specifically intended as consumer products for the
`personal use of a consumer around a house. These specifications are not intended to apply to
`commercial products customarily used by hired operators or to products designed primarily for agricultural
`purposes such as defined in SAE J1116. They are not intended to cover sulky-type units, pedestrian-
`controlled tractors, flail mowers or sickle bar mowers, and are not intended to completely cover electrical
`requirements. This standard applies to all aftermarket parts, attachments and accessories. Any
`manufacturer of aftermarket parts, attachments and accessories is responsible for ensuring compliance to
`this standard. Safety specifications
`in
`this standard apply only
`to a configuration of
`attachments/implements/accessories approved by their respective manufacturers.
`The U.S. Consumer Product Safety Commission (CPSC) has promulgated a mandatory standard relating
`to certain aspects of pedestrian-controlled power lawn mower operations (SAFETY STANDARD FOR
`WALK-BEHIND POWER LAWN MOWERS, CPSC 16 CFR PART1205). A copy of the CPSC mandatory
`standard is contained in Annex C. The CPSC standard contains requirements for products sold in the US
`by manufacturers of consumer pedestrian-controlled lawn mowers that meet any of the following criteria：
`a) Cutting width between 305 mm (12 inches) and 762 mm (30 inches)
`b) Mass less than 90.7 kg (200 pounds)
`c) Engine horsepower less than 6 kW (8 hp).
