Sort of. It all starts as natural gas like we get from gas wells, or the gas that is associated with oil wells. Mostly pure methane (CH4), but includes some heavier hydrocarbon components such as ethane, propane, butane, etc. These components exist as a gas at normal atmospheric pressures. As you go from methane to the heavier components, you have more energy. Gas producers usually process the gas produced from wells to separate out the heavier components, as they are usually worth more even after the expense of processing. So that is where we get the butane we use in torches and the propane (LP = liquid propane) for our barbeque grills or for home heating. The butanes and propanes have to be kept in pressurized tanks. The ethane is almost all used in the petrochemical industries, such as the base feedstock for many plastics. Since we get more energy as we move from methane to the heavier components, that is why it takes a pretty big tank of CNG (compressed natural gas) to run a car. The propane tanks on LP tractors would have to be several sizes bigger to run the same amount of time if they used CNG. And if you continue down the hydrocarbon chain, you eventually get to acetylene that we use for cutting torches, because it has so much more enrgy than butane or propane.

It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
