Description In India sugarcane is an important commercial crop occupying about 4.4 million hectares of
land with an annual sugarcane produce of 283 million tonnes. One of the biggest problems faced by the
sugarcane growers is the disposal of trash. To overcome this problem the farmers usually burn
sugarcane trash which causes harmful impact on the environment and leads to loss of nutrients. On the
other hand, trash mulching has been found to be advantageous in increasing the soil fertility and
conservation of soil moisture. However, the trash size in the field is of large size so it needs to be
reduced in size to increasing the composting process. Keeping in view the above problems, a prototype
of sugarcane trash chopper cum spreader was developed to chop the trash and spread it to the field
uniformly. The dimensions of the prototype were 4100 mm x 1840 mm x 1910 mm. The machine was
tested at five levels of moisture content viz. M1, M2, M3, M4, M5 having values 18.75%, 16.54%,
15.15%, 13.19% and 13.13% (db) respectively and four different velocities V1, V2, V3, V4 having
corresponding values of 2.76, 2.8, 2.9 and 3.2 km h

. The maximum shredding capacity of the machine
was found to be 4.31 t h
-1
at moisture content of 13.13 % and forward speed of 2.9 km h
-1
with
maximum shredding efficiency of 90.4 per cent. The prototype chopped up sugarcane trash of about 4
to 12 cm length. The average field capacity of the machine was found out to be 0.40 ha/h with
efficiency of 78.2 per cent. The uniformity of trash spreading varied from 0.90-0.95. The cost of
operation of the machine was found to be Rs. 786/h. the B:C ration was 1.5 and payback period of the
machine was 1.3 year if operated for 250 hours per year. The break-even point of machine was 17.7 ha.
