3 Definitions For the purposes of this standard, the definitions given in EN 292-1:1991 apply together with the following: 3.1 pedestrian controlled tractor: Agricultural self-propelled machine designed to be pedestrian controlled, capable of driving and/or pulling different working tools (see Figure B.1). 3.2 tool: Working element which can be adapted to a pedestrian controlled tractor. 3.3 mounted rotary cultivator: Tool used for working the soil composed of a group of rotating elements which can be adapted to a pedestrian controlled tractor. 3.4 motor hoe: Agricultural self-propelled machine designed to be pedestrian controlled with or without support wheel(s), in such a way that its working elements act as hoeing tools to ensure propulsion (see figure B.2). 3.5 motor hoe with drive wheel(s): Agricultural self-propelled machine designed to be pedestrian controlled and propelled by one or various wheels directly actuated from the engine and equipped with hoeing tools (see figure B.3). 3.6 handlebar: Device equipped with grips enabling the machine to be manually controlled. 4 List of hazards The list of significant hazards dealt with in this standard is given in Annex A. Annex A also indicates the hazards which have not been dealt with.
5 Safety requirements and/or measures 5.1 General Unless otherwise specified in this standard, the machine shall comply with the requirements of tables 1, 3, 4 and 6 of EN 294:1992. The requirements of prEN 1553 apply where relevant.5.2 Starting device In addition to the hold-to-run controls (see 5.5), the machines shall be equipped with a device which prevents the engine starting if the start-up can induce rotation of the wheels or movement of the tool. The type of device which can be considered as fulilling this requirement is one which, for example, by a mechanical linkage only allows the engine to start when the gear lever is in neutral and the tool is declutched. Such a device is not necessary if, when starting the machine according to the instructions, the operator is not required to be in the danger zone. The danger zone is taken as the longitudinal band defined by the width of the machine and tool extending both forward and rearwards from it. If the machine is not provided with reverse gear, the danger zone to the rear of the machine is limited to a distance of 550 mm as measured from the rear extremity of the protective devices for moving parts (see figure 1). In the case of a machine provided with reverse gear, the danger zone to the rear includes the whole longitudinal zone limited by the working width of the equipment. Should the operator have to lean on the machine to start the engine, the appropriate place shall be indicated or an identified support provided with a corresponding indication. With the exception of hand cranks (see ISO/DIS 11102-1 and ISO/DIS 11102-2), starting devices shall be integral with the machine (e.g. recoil pull start). Loose belts, cables, etC. are not accepted. |f starting is achieved by means of a hand crank it shall be equipped with a device that disconnects the hand crank immediately when the engine starts and prevents its connection when the engine is running or kick-back during starting.
