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.
