• In case of pulling, the pulling force is applied in the upward direction which reduces normal reaction force and hence reduces frictional force. So force opposing the motion is reduced, hence pulling is easier.

Answer 2

Answer:

In pushing frictional force is greater than that of in case of pulling. When you push you to add some normal of mg, so friction also increases but in case of pulling at the time you are pulling you decrease the normal so friction reduced therefore, pulling the lawn roller is preferred than pushing the lawn roller.
