A Bronx teen was arrested for breaking into a Queens construction yard and taking a massive excavator out for a destructive spin around the block, cops said.

Allan Swafford, 17, was slapped with a slew of charges, including felony criminal mischief, after he allegedly broke into a Far Rockaway construction trailer on March 20, grabbed keys for the machine and rampaged across a nearby playground, causing more than $100,000 in damage.
