Can I cut lower branches off Lilly Pilly?

[Chintah]

Hi, this Lilly Pilly is about 3 years old. Its planted in the lawn and we would like it to have a clean trunk so it can be mowed under. Will the trunk get taller as the tree grows or should we be cutting off the lower branches. Also if the lower branches were cut off would that give the tree more energy towards growing taller. The lower branches are up to approximately 2 to 3 cm diameter. 

Thanks.

We probably won’t risk it in that case. Thanks heaps for your advice.
