Abstract
With a higher HP tractor it is difficult to take the maximum use of tractor power. Front three-point linkage has been found profitable with these tractors due to higher power requirement and also due to multiple operations in single pass. The importance of this study is to check its feasibility under Indian field conditions. Front three-point linkage are designed and fabricated according to Category II hitch requirements. Hydraulic cylinders are designed to provide hydraulic power to the front linkages. Selection of hydraulic hoses is done according to the requirements and availability. Mechanical front-wheel drive tractor is selected for the test. Laboratory test is carried out to evaluate its lifting performance. Field performance is also done to check its profitability. A field is prepared using cultivator in front and harrow in rear and the performance are calculated.
