IS 12224 : 2025 Hydraulic Power and Lifting Capacity of Agricultural Tractors - Methods of Test
1 SCOPE
This standard specifies test procedures for determining following hydraulic performance characteristics of agricultural tractors:
a) The maximum static vertical force which can be exerted by the hydraulic lift at the lower hitch points and at a point 610 mm rear to lower hitch points throughout its power range;
b) The maximum static vertical force which can be exerted by the hydraulic lift, at a point 610 mm to the rear of the hitch points on a frame attached to the three-point linkage, throughout its full range of movement;
c) The hydraulic pump and relief valve performance; and
d) The ability of the lifting system to maintain the load in the lifted position without hydraulic power.
