    Performance evaluation of battery operated tractor
    (CCSHAU, Hisar, 2021-08) Shinde, Vyankatesh Shankarrao; Jain, Mukesh
    Farm mechanization is one of the most important elements of modernization of agriculture. Agricultural tractor is an integral part of agricultural mechanization and has a crucial role in increasing agricultural productivity. The diesel engine agriculture tractor requires fuel to produce energy, due to burning of fuel, it produce GHG which affect adversely on environment. Diesel engine tractor require periodical maintenance, emits high noise, produce more vibration. The increasing cost and limited resources of diesel fuel, increasing pollution, calls to use alternate energy source for agriculture tractor. Therefore, study, on performance evaluation of battery operated tractor was carried out. The present study was undertaken to assess the various performance tests like drawbar test, noise test, vibration test, field test, haulage test etc. and operating cost analysis of ET. The performance evaluation of the ET was conducted at NRFMTTI, Hisar. The maximum drawbar pull and drawbar power of ET with gross weight of 1005 kg were measured as 7.35 kN and 8.26 kW, respectively, with limiting wheel slip of 15 %. ET produces very low noise, and produces low level of vibrations during work, which will assure a nice working environment, without any negative effect on operator. The maximum noise produced at bystander’s position and at operator’s ear level was 73.3 dB (A) and 76.3 dB (A), respectively, which was 13.76 % and 20.52% lower against the maximum permissible limit of 85 dB (A) and 96 dB (A) as per IS 12207:2019. Noise was also measured during field operation with rotavator at bystander’s position and operator’s ear level which was measured as 73.9 dB (A) and 82.3 dB (A), respectively. The amplitude of mechanical vibration on ET was approximately 52 per cent less than the requirement of IS 12207:2019. The actual field capacity with rotavator and M B plough were 0.250 hah−1 and 0.125 hah−1, respectively with 82.38 and 92.05 per cent field efficiency. The battery power consumption during field operation with rotavator and M B plough was observed as 4.52 to 5.3 kWh−1 and 1.4 to 2.05 kWh−1, respectively. Specific battery energy consumption during haulage test was observed as 0.15 to 0.16 kWhkm−1t−1. During the haulage test, battery consumption per km was observed as 0.22 to 0.24 kWhkm−1. The cost of operation of electric tractor with rotavator was Rs 1324 per hectare and Rs 332 per hour.
