Trash burning is a major problem in sugarcane to overcome this, a sugarcane trash chopper cum spreader was tested at farmerâ€™s field for its performance and economic feasibility. The chopper cum spreader was tested at five levels of moisture content of trash (13.2, 14, 15.15, 16.6, and 18.8% db) and five levels of operationalspeed (2.6, 2.8, 2.9, 3.1, and 3.4 km/h). The performance of the sugarcane trash chopper cum spreader heavily depends on moisture content and speed of operation. The maximum field capacity (0.43ha/h) was obtained at a speed of 3.2 km/h, but maximum shredding efficiency (90.40%) was found at a speed of 2.9 km/h. Maximumuniformity coefficient (0.95) and shredding capacity (4.31 t/h) was obtained at a speed of 2.9 km/h and at a moisture content of 13.13%. Maximum trash lifting efficiency (93.95%) was observed at a speed of 2.76 km/h and at a moisture content of 13.13%. The cost of operation was Rs. 2015/ha with B: C ratio of 1.5. The break-even point ofthe chopper cum spreader was 17.7 ha and payback of the machine was 1.3 years if operated for 250 h/year. The energy consumption of machine was calculated to be 1327.7 MJ ha-1. The optimum performance of sugarcane trash chopper cum spreader was obtained at a moisture content of 13.13% (M5) and forward speed of 2.9 km h-1 (V3). The sugarcane trash chopper cum spreader may be recommended for chopping of sugarcane trash for mulching to avoid burning of trash and conserving natural resources.
