The tractor drawn ginger harvester cum elevator was developed with an objective to have mechanical means for harvesting of ginger crop. The components were designed and developed keeping in view the relevant crop, soil and machine parameters. The machine consisted of a main frame, digging blade, depth gauge wheel, vibration unit, power transmission system, and conveying mechanism. The performance evaluation of developed machine was evaluated at Chitta village of Bidar district of Karnataka State. The experiment was undertaken in red clay soil; the observed moisture content was 13.50 per cent moisture content (db) at the time of harvesting. The size of the experiment plot was 0.2 ha was taken for observations. During field testing of machines, draft, digging efficiency, per cent damage of ginger rhizome and fuel consumption, separation index and conveying efficiency were calculated. The theoretical field capacity, actual field capacity and field efficiency were also measured. The ginger harvester cum elevator was tested at a forward speed of 2.5 km h-1. The draft and power requirement for harvesting ginger crop using harvester cum elevator was found to be 2625.82 N and 1.82 kW respectively. Fuel consumption for particular operation was observed to be 5.03 l h-1. Theoretical field capacity, effective field capacity and field efficiency of ginger harvester cum elevator was calculated 0.22 ha hr-1, 0.18 ha hr-1 and 81.80 ha hr-1 respectively. The digging efficiency, damage of rhizome, separation index and conveying efficiency of ginger harvester cum elevator was recorded to be 99.18 ha hr-1, 1.06 per cent, 85.38 per cent and 99.72 per cent respectively.
