When tractors were first developed, they used enormous steam engines that were notoriously unreliable and hard to maintain. These were phased out around the turn with the twentieth century and substituted for internal combustion engines which were smaller though powerful and ran on a number of fuels including kerosene, ethanol and gasoline.

Music, as some research has revealed, boosts the production of serotonin, which is accountable for the feel-good sensation in you.

Productivity went up by the huge margin and absenteeism dropped. The inter-collegial relationship improved and overall the atmosphere of such workplaces improved considerably. As a direct result of those changes, staffing turnover also came down and with it the charge in training and orienting personnel of their jobs.
