There were, witnesses said, five to seven young men riding the 20-ton John Deere front end loader down 24 Avenue early Sunday morning.
The stereo in the cab of the 20-ton rig was blasting music over the sound of the 232 horsepower engine.
The big tractor was stolen from a locked compound at Stokes Pit near the Langley-Surrey border around 1 a.m.
As it was making its way eastward down the 19900 block of 24 Avenue, the loader flipped over a Ford F350 pickup truck, leaving the smaller vehicle on its side.
Shortly after that the youths abandoned the loader and fled on foot.
According to one unofficial account, the John Deere was brought to a halt by a local resident who jumped into the cab to stop it from hitting a gas station and pub.
The Air 1 police helicopter was called in, but either it nor a police dog could locate the joyriders.
The loader was recovered undamaged and returned to the owner.
Police are asking anyone with information that might assist in identifying the suspects to call the Langley RCMP at 604-532-3200 or if you prefer to remain anonymous, call Crime Stoppers at 1-800-222-TIPS (8477).
