Product Code:SAE J708
Title:Agricultural Tractor Test Code (Cancelled May 2003)
Issuing Committee:Atsc Test Standards Subcommittee
Scope:The purpose of this SAE Standard is to define test conditions, give a description of the tests to be made, specify data to be obtained, show formulas and calculations, define terms, and establish a uniform method of reporting so that performance data obtained on various makes and models of tractors, tested in accordance with this document, will be comparable regardless of where the test is made. It is obvious, because of the many present day tractor models available in a number of types with numerous items of special or optional equipment, that the scope of this document must be limited to obtaining and reporting only the most significant of widely used performance data.Outline of CodeSection 3 DefinitionsSection 4 Test ConditionsSection 5 Detailed Description of Test Procedure5.1 Preparation of Tractor for Performance Runs5.2 Mechanical Power Outlet Performance5.2.1 Maximum Power Fuel Consumption5.2.2 Varying Power Fuel Consumption5.2.3 Power at Standard Power Take-Off Speed (This run is made only when the engine speed at SAE standard power take-off speed does not correspond to the engine speed at the maximum power run (5.2.1).)5.3 Drawbar Performance5.3.1 Maximum Drawbar Power5.3.2 Varying Drawbar Power Fuel Consumption, Including Sound Level at Operator Station5.3.3 Drawbar Pull Versus Travel Speed5.3.4 Exterior Sound LevelSection 6 Final InspectionSection 7 Calculations and FormulasSection 8 Uniform Method of Publishing Results
