Abstract	Farm power and equipment role was established in agriculture beyond doubt for sustainable development but hill farming is still facing shortage of farm power and matching equipment for timely and precisely operations. A study was carried out on performance evaluation of different light weight power tillers/weeders designated as P$_{1}$, P$_{2}$, P$_{3}$ and P$_{4}$ under dry and wet land conditions to meet out the demand of farm power for mechanizing hill agriculture, particularly under small and irregular shaped terraces having high vertical intervals where it is difficult to operate commercially available power tillers. Four power tillers in the horse power range of 3.0–7.0 hp manufactured and marketed by Indian firms were tested in silty-clay-loam soil at the HPKV farm, Palampur, India. The results showed that the depth of operation was less than 80 mm with P$_{1}$, P$_{2}$ as well as P$_{3}$ power tiller after two passes of rotary at soil moisture content of 16.4% whereas, it was 102 mm with P$_{4}$. The average effective field capacity was 0.055, 0.051, 0.042 and 0.060 ha/h under dry land conditions with P$_{1}$, P$_{2}$, P$_{3}$ and P$_{4}$, respectively whereas in wetland condition the capacity was 0.042, 0.038 and 0.05 with P$_{1}$, P$_{2}$, and P$_{4}$, respectively. P$_{3}$ power tiller could not be possible to test under wet land conditions due to less ground clearance of the engine. The cost of repair and maintenance was observed to be very high in case of P$_{1}$, P$_{2}$ and P$_{3}$ power tillers due to the occurrence of frequent breakdowns. It was construed from the study that the power tillers up to 5 hp are not suitable for seed-bed preparation but it could be used as weeder for interculture operations in wide row spaced crops. However, P$_{4}$ power tiller performed better than other models under different conditions. There was saving of 50–66% in time and 66–75% cost of operation observed with different makes of power tillers as compared to bullock ploughing.
