why the back wheel in the tractor is bigger than the front
wheel?
Answer Posted / rockyfire
rear wheel is needed for producing maximum traction i.e.
grip on the ground therefore its area should be more.In
addition to this fact,it is also imp to give max torque and
min speed which is possible only when the size of the wheel
is large.On the other hand,front wheel is only used for
steering purpose so it's size should be kept small.
