Figure 1 — Volume of “hand reach zone” and “foot reach zone” 5.4 Marking of controls Controls, whose purpose is not obvious, shall have the function, direction and/or method of operation clearly identified by a durable label or mark. Detailed instructions on the operation of all controls shall be provided in the instruction handbook. If symbols are used for marking controls, they shall correspond to those in ISO 3767-1:1991 and ISO 3767-3:1995. 5.5 Controls of the movement of the machine and of the blade(s) On motor mowers which are self-propelled it shall be possible to engage or disengage the traction drive when the cutting blade is operating. The movement of the machine and the movement of the blade(s) shall be possible only by actuating hold-to-run controls. The hold-to-run controls shall be located on at least one of the handlebar grips. Motor mowers shall be fitted with a device on the control handle which will automatically stop blade movement when the operator's hands are removed from the handle. For restarting blade movement the hold-to-run control shall require two separate actions. SIST EN 12733:2001+A1:2009

Except for an arc at the front of the machine concentric with the cutting blade tip circle and extending up to 90° on either side of the line of working, and up to 30° more on the side from which the grass is ejected (see Figure 5), the casing shall extend vertically at least 3 mm below the plane of the cutting blade tip circle. This requirement shall not apply to the fastening elements of the cutting blade(s) extending downwards if they lie within a concentric circle whose diameter is half that of the outer cutting blade tip circle. For every section of the perimeter of the cutting blade tip circle with less than 3 mm overlap, the casing, a deflector or barrier shall prevent access to the cutting blade. This requirement is considered to be satisfied if either:  this zone (see Figure 5) is provided with a barrier located at a minimum horizontal distance of 200 mm from the cutting blade tip circle and at a maximum vertical distance of 400 mm above the ground; or  this zone shall satisfy the foot probe test in annex D.
