Detailed Solution

Suppose the roller is pushed as in figure (b). The force F is resolved into two components, horizontal component $F_{H}$ which helps the roller to move forward, and the vertical component acting downwards adds to the weight. Thus weight is increased. But in the case of pull [fig (a)] the vertical component is opposite to its weight. Thus weight is reduced. So pulling is easier than pushing the lawn roller.
