IS 14980 : Part 1 : 2024/ISO 8759-1: 2018 Agricultural Tractors - Front-Mounted Equipment - Part 1 Power Take-off - Safety Requirements and Clearance Zone Around PTO
NATIONAL FOREWORD
This Indian Standard (Part 1) (First Revision) which is identical to ISO 8759-1 : 2018 'Agricultural tractors - Front-mounted equipment - Part 1: Power take-off - Safety requirements and clearance zone around PTO' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Agricultural Machinery and Equipment Sectional Committee and approval of the Food and Agriculture Division Council.
This Indian Standard (Part 1) was published in 2001 under the title 'Agricultural wheeled tractors - Front-mounted equipment - Part 1: Power take-off and three-point linkage' as an identical adoption of ISO 8759-1 : 1998 under dual numbering. ISO 8959-1 was subsequently revised in 2018 splitting it into three parts Part 1, Part 3, and Part 4 under the general title 'Agricultural tractors - Front-mounted equipment'. The main modifications are as under:
a) The general specifications of the power take-off and the location requirements have been moved to a new part, Part 3;
b) The specifications of the three-point linkage have been moved to a new part, Part 4;
c) Specifications for PTO type 4 have been added;
d) The dimensions for the tractor master shield and clearance zone have been updated; and
e) The dimensions of the protective device/tractor master shield and the clearance zone have been presented in one figure.
The first revision of IS 14980 (Part 1) has been undertaken to align with latest version of ISO 8759-1 published in 2018.
IS 14980 is published in four parts. The other parts in the series are as under:
Part 2 Stationary equipment connections
Part 3 Power take-off - General specifications and location
Part 4 Three-point linkage
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
