The agreement on AGR/CA/T(2005)5 at the 2005 Annual Meeting as quoted in point 7.3 on page ten of AGR/CA/T/M(2005) is the first step toward a more accurate description of the front hard point in case of overturning. The second step is to establish a common rule to choose the front hard point. It is possible to sent to testing stations a questionnaire asking them to answer very simple questions about this subject? Answers could be elaborated and discussed to reach a common method to choose the front hard point. The third, and more difficult, step is to propose a testing procedure to verify if really the front hard point, in case of overturning, is able to bear the part of the mass of the tractor standing on it. From previous experience a solution may be found: the rear hard fixture for 2 post protective structure on track-laying tractors (Code 8). A similar approach could be adopted. An alternative option is to work strictly in relation with tractor and/or protective structure manufacturers performing experimental tests, with a method that simulate the reality of the overturning, on front hard points in order to record the maximum force that they are able to withstand. It could be possible to do that during normal testing activity with the agreement of the manufacturers. Data collected will be useful, first of all, to know better if the problem exists or not. And if it exists to define a method to test the front hard point and include the results on the test report.

Abstract
The agreement on AGR/CA/T(2005)5 at the 2005 Annual Meeting as quoted in point 7.3 on page ten of AGR/CA/T/M(2005) is the first step toward a more accurate description of the front hard point in case of overturning. The second step is to establish a common rule to choose the front hard point. It is possible to sent to testing stations a questionnaire asking them to answer very simple questions about this subject? Answers could be elaborated and discussed to reach a common method to choose the front hard point. The third, and more difficult, step is to propose a testing procedure to verify if really the front hard point, in case of overturning, is able to bear the part of the mass of the tractor standing on it. From previous experience a solution may be found: the rear hard fixture for 2 post protective structure on track-laying tractors (Code 8). A similar approach could be adopted. An alternative option is to work strictly in relation with tractor and/or protective structure manufacturers performing experimental tests, with a method that simulate the reality of the overturning, on front hard points in order to record the maximum force that they are able to withstand. It could be possible to do that during normal testing activity with the agreement of the manufacturers. Data collected will be useful, first of all, to know better if the problem exists or not.
