Why is it easy to pull a lawn roller than to push it?

While pulling a lawn roller, the vertical component of the force applied acts in upward direction which decreases the apparent weight of the lawn roller. i.e.

Wapparent = mg-Fv

While pushing the lawn roller, the vertical component of the force applied acts in downward direction eventually increasing the apparent weight of the lawn roller. i.e.

Wapparent = mg-Fv

Hence, it is easier to pull a lawn roller than to push.
