Jack, 15, invents 'tractor safe lock' after grandad's farm accident

Jack Nagle told his grandfather he was going to invent a device that would prevent accidents like it from happening in the first place. The now 15-year-old’s tractor safe lock, a device that automatically engages the handbrake when the driver leaves the seat, is patent pending.
Mr O’Sullivan had been working on his suckler farm in Beaufort, Co Kerry when he got off his tractor to attend to something.
