Which of the following parts of a tractor is most essential in operating a mower?
Answer Details
The most essential part of a tractor in operating a mower is the power-take-off (PTO) shaft. This is because the PTO shaft transfers the power from the tractor's engine to the mower's cutting blades, which enables the blades to rotate and cut the grass. Without the PTO shaft, the mower will not receive power and will not be able to function.
