1 Scope The requirements provided in this standard are for powered walk-behind rotary tillers and hand-supported cultivators. This standard is intended to provide safety and design requirements to help ensure uniform operator environments, exclusive of the power source. This standard shall apply to machines specifically marketed for consumer / personal use. This standard does not apply to commercial or agricultural machines or machines primarily for agricultural purposes such as defined in ANSI/SAE J1116 or SAE J1150. This standard does not apply to tractor mounted or drawn tillers or to cultivator attachments which are adaptations of, or accessories to, handheld string trimmers and brushcutters covered by the applicable ANSI/OPEI B175 standards. This standard is not intended to completely cover electrical requirements. 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. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard. All standards are subject to revision, and parties to agreements based on this American National Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

3 Definitions 3.1 actuating device: A handle, lever, switch, or similar control required to start the motion of tines or wheels. 3.2 clutch: A device used for engaging or disengaging the load from the power source. 3.3 durable label: A label that shall meet the requirements of clause 10. 3.4 emergency stop control: A control which stops power to the traction drive and tines independent of the operator presence control. 3.5 engine (motor) start: The change of engine state from not producing power to producing power. 3.6 guard or shield: A barrier that minimizes inadvertent personal contact with hazards. 3.7 hand-supported cultivator: An operator-controlled (walk-behind) powered rotary cultivator with the following attributes: a dry weight under 16 kg (35.3 lb), no more than two wheels, the operator provides support or attitudinal control of the machine throughout its use, and its rotating tines/tool(s) ensure propulsion away from the operator. 3.8 manual start: Utilization of operator force to cycle the engine for starting purposes. 3.9 normal operation: Use of the machine which is reasonably foreseeable and which is consistent with such activities as starting, stopping, tilling/cultivating, fueling, connecting to (or disconnecting from) a power source. 3.10 operator hand control position: The area within which all hand controls requiring operation from the operator zone shall be located. 3.11 operator presence control (normally off control): A control requiring continuous operation by the operator and designed so that it will automatically stop power to a drive when the operator’s actuating force is removed. 3.12 operator zone: The area occupied by the operator during normal operation of the machine as illustrated in figure 1.
3.13 powered walk-behind rotary tiller: A tilling machine with powered rotary tines, with or without traction drive, that is intended to break up soil and is controlled by the operator walking behind the machine. 3.13.1 front tine: A powered walk-behind rotary tiller designed to be operator controlled, with support wheels whose ground traction is provided by its forward positioned rotating tines. 3.13.2 rear tine: A powered walk-behind rotary tiller whose ground traction is provided by the drive wheels and whose rotating tines are behind the drive wheels. 3.13.3 traction drive: A mechanical drive system with independent control that powers the drive wheels. 3.14 shall: The word “shall” is to be understood as a requirement. 3.15 should: The word “should” is to be understood as a recommendation. 3.16 test operator: An operator with the dimensions and reach as shown in figure 1. 3.17 tine barrier: Structural members, such as transport wheels, portions of the tiller frame, ground stake, or any combination of these members, that restrict entry of the operator into the rotating tines. 3.18 tines: That portion of the rotating member that engages and penetrates the soil. 4 Machine identification The machine shall be provided with identification giving at minimum the following information: a) Name of the manufacturer or supplier, b) Markings that uniquely identify the machine (such as, model and/or serial number), and c) Contact information for a source of replacement parts. The label(s) shall meet the durability requirements of clause 10.
