The rescue chopper was called to a private property, in the Western Downs region, after 3:15pm.
It’s believed the man, aged in his eighties, had been walking across a cattle grid, when his foot became stuck.
The patient told rescuers he grabbed a nearby quad bike, to steady himself, but accidentally activated the accelerator.
The vehicle reportedly shifted, dragging him, while his foot was still trapped in the grid.
Queensland Ambulance Service (QAS) paramedics were already on the scene, when the aeromedical team arrived.
The man was stabilised, before being flown to Toowoomba Hospital in a stable condition, with lower limb injuries.
