Tractors for agriculture and forestry - Roll-over protective structures on narrow tractors - Part 1: Front-mounted ROPS

Specifies procedures for both the static and dynamic strength testing of roll-over protective structures (ROPS) front-mounted on narrow tractors. It defines the clearance zone and acceptance conditions for rigid or tiltable, front, two-post ROPS, including any associated rear fixtures, and is applicable to tractors so equipped having the following characteristics: 1) a ground clearance of not more than 600 mm beneath the lowest points of the front- and rear-axle housings (not considering lower points on the axle differential); 2) a fixed or adjustable minimum track width of one of the two axles of less than 1 150 mm; 3) a mass greater than 400 kg but less than 3 500 kg, unballasted, including the ROPS and tyres of the largest size recommended by the manufacturer; 4) fitted with roll-over protective structures of the dual-pillar type mounted only in front of the seat index point (SIP) and characterised by a reduced clearance zone attributable to the tractor silhouette. This document also specifies optional testing procedures for both seat anchorage points and folding efforts of front-mounted ROPS designed to fold.
