Performance Evaluation of Tractor Operated Sugarcane Stubble Shaver
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
Sugarcane stubble shaving is an important field operation followed for harvesting of sugarcane crop in ratoon management practice. Sugarcane, apart from being a vital source of sugar provides a fair amount of raw material for sugarcane industries. In ratoon management practice, where sugarcanes are harvested at just above the ground level to allow the sprouting of stems for next season, tractor operated stubble shaver is a suitable machine in harvesting operation. A sugarcane stubble shaver was procured from market and was evaluated for its field performance at the College of Agricultural Engineering, Raichur. During the harvesting operation by stubble shaver for 22.5 h, various field performance parameters were evaluated. The average field capacity, mass of stubble in 10 m strip after the slashing operation, mass of stubble per unit area were recorded as 0.44 to 0.48 ha h-1, 12.35 to 14.10 kg, 1.12 to 1.45 kg m-2 respectively. The average stubble height after the operation was recorded as 32 to 43 mm. The average wheel slippage was observed as 4.1 to 7.3 per cent. The fuel consumption of tractor while operating with stubble shaver was observed as 4.4 to 5.2 L h-1. The results of wear analysis of cutting blades on dimensional basis and mass basis were recorded as 0.02 to 0.18 and 0.12 to 0.25 per cent, respectively. The hardness of cutting blade was observed to be 29.2 to 33.1 HRC. Hence, the performance of sugarcane stubble shaver in field was satisfactory and was duly recommended for use in ratoon management practice, as it reduces the cost of operation and drudgery involved in manual harvesting.
