Rice (Oryza sativa) is one of the most important food crops in India. India is the second largest producer and consumer of rice in the world. Rice production in India crossed the mark of 100 MT in 2011-12 accounting for 22.81% of global production in that year. The productivity of rice has increased from 1984 kg per hectare in 2004-05 to 2372 kg per hectare in 2011-12. In paddy cultivation, harvesting and threshing are the most important operations, which are laborious involving human drudgery and requires about 150-200 man-hr/ha for harvesting of paddy. Timely harvesting is one of the important aspects, as delayed harvesting leads to loss of grain and straw owing to over maturity results in loss of grains by shattering. The efficiency of skid lifter guard was about 9.67% more than half moon lifter and 15.11% more than without crop lifters. The grain losses per acres were 25 kg this is less when compared with half moon lifter and without lifter. The time of operation of combining with skid lifter was found as 1hr where as by using a half moon lifter and without lifters were 1hr 15 min and 1hr 30 min respectively. It is observed that about 30 min time was saved with skid lifter attached to combine when compared with without crop lifter and about 15 min was saved with half moon lifter attached to combine when compared with without crop lifter. The cost of operation for the combine attached with skid lifter was found as Rs. 2500 where as in the case of combine attached half moon lifter it is found as Rs. 3125 and it is found as Rs. 3750 in case of without using any crop lifters.
