ABSTRACT
Study was under taken to find the variations in dimensions related to three point linkage and PTO of available tractors of different horse power range, so as to find out a range for standardization of dimensions of three point hitch system and PTO for available tractors. A total of 45 tractors of different makes were divided into five categories depending on their horse power viz. below or equal to 35 hp, 36-45 hp, 46-55 hp, 56-65 hp and above 65 hp. All tractors of all hp categories had the PTO diameter in the range of 34 to 35 mm. Exposed length of PTO spline for 67 % tractors was in the range of 100-140 mm. Horizontal distance of PTO end from centre line passing through lower links for 62 % tractors was in the range of 450-550 mm. Distance of lower hitch point from centre line of rear tire for 53 % tractors was in the range of 250-400 mm. Horizontal distance between the free ends of lower hitch points for 69 % tractors was in the range of 700-950 mm.
