The ever increasing energy demand, unemployment in developing countries like India, Increased awareness of people towards the health are some of the driving forces for the development of powered machines. The experimentation has been carried out on a fodder cutter energized by electrical power. Fodder-cutter machines are used every day by farmers and their families in India for preparation of fodder for the livestock they own. This paper discus about the procedure of the testing of fodder cutter machine.

: A proper placement of seed in field is most important operation in order to obtain optimum yield of crop. Day by day the land fragmentation was increased and which resulted near about 65 pre cent of the land holders are small and marginal land holding capacity in the region. Considering the limitations due to costly seed, traditional method of manual dibbling, labour shortage and small marginal land holding pattern there is need of small manual planter for small and marginal land holders. In view of the above, the manually operated seed planter was tested at Deptt. of Farm Power and Machinery, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. A single row cotton planter was evaluated for performance by conducting laboratory and field tests. In laboratory test calibration of planter for seed rate, uniformity of seed planting and percentage of seed damage was determined at three cell plate, two gear ratio and level of seed in hopper. Based on the laboratory test cell plate, gear ratio and level of seed in hopper were selected for field test. The three trials of planter were taken for planting Bt-cotton crop. The field tests comprised of determination of effective field capacity, average depth of placement of seeds in the furrows and mean spacing of seeds within each row. The rate of work was observed to be in the range of 0.18 to 0.21 ha/h at forward speed of 2.24 to 2.5 km/h in well prepared seed bed along with the opened furrows. The average depth of planting was observed in the range of 4.5 cm to 5cm. The field efficiency of the planter was observed in the range of 88.88 to 91.1 per cent.

: This paper covers work carried out at Department of Farm Power and Machinery, , Dr. PDKV, Akola. This paper discussed about the performance of the exiting bullock cart on various roads by using the different kind of materials. Drawbar test, track test and haulage test were carried and evaluated the performance of bullock cart. It was found that the pull increased as the laden mass of cart increased on various kinds of roads with the different types of loading materials. The forward speed decreased with continuous work as the laden mass of cart increased on various kinds of roads with the different types of loading materials. The wheel slippage increased as pull increased with laden mass of cart increased for various type of roads. It was observed that the bullock could pull one tonne load at a forward speed of 2 to 3 km/hr with continuous work of 3 hrs. At turning it needs to reduce speed of travel and more attention should give by operator, when cart is fully loaded in order to avoid accident.

The performance of the straw cutting mechanism equipped with plain blade straw cutting disc and a pair of twin press wheels assembly was evaluated in soil bin laboratory on a wide range of straw densities from 3000 to 5000 kg/ha at forward speed of carriage 2.5 km/h and speed ratios of 5.20, 6.94 and 8.67. The relative effect of the variables of speed ratio, pair of press wheels and straw density on the responses of horizontal force (F h), vertical force (F v), power consumption, straw cutting percentage and clogged straw were studied. The F h requirement was observed to be 12.16, 12.50 and 13.59 kgf at 3000, 4000 and 5000 kg/ha straw density, respectively at 5.20 speed ratio and the F v requirement was observed to be 27.58, 29.91 and 32.82 kgf at the same straw density levels and speed ratio. The draft and vertical forces increased with the increase in the rotational speed and straw density. The power consumption of straw cutting mechanism was estimated to be 192.66, 280.23 and 356.33 W and straw clogged was found to be 7.58, 4.51 and 6.22 kg/ha at the same straw density levels and speed ratios. The observations and data indicated that the straw cutting performance of the plain blade disc straw cutting mechanism was 100per cent at all straw density levels and speed ratio.

A 3-row bullock drawn cotton planter was evaluated on field of the Department of Farm Power and Machinery, Dr. PDKV, Akola using NHH-44 variety of cotton. The average moisture content of soil was 33 per cent. The field performance tests conducted over an 0.182 ha area revealed that the average horse power for the planter was 0.467 for an average draft of 48.53 kgf and average speed of 2.6 km/hr. The theoretical field capacity, effective field capacity, field efficiency obtained for continuous operations of planter were 0.47 ha/day, 0.34 ha/day and 72.51 per cent, respectively. In view of the above performance it can be concluded that newly developed bullock drawn cotton planter is suitable for cotton planting.
