The purpose of the implement development was to cover more filed in a single pass for reducing the operational time, collect the uprooted residues and to leave it in one end of the ground. Spin groomer designed by using a “solid work 2018 software” and developed in a workshop. Major component of the developed implement is Mainframe, 3-point hitch, circular wheel, pegs and rake.

GoPower tabletop press for around US$1,000. Although the press usually comes with a 240V/50 cycle electric motor, you can buy the press with a 120V/60 cycle motor from the U.S. distributor. The press looks like a powerful juicer. To operate it, pour the oilseed into the funnel and wait for the vegetable oil to pour out of the bottom. The meal oozes out of the side of the press. The Three Ways to Use Vegetable Oil as a Fuel Diesel engines that are found in cars, trucks, generators, boats, buses, trains, planes, pumping stations, tractors, and agricultural equipment can all...
