Thanks for that Joe, I have just done some research and that is correct mate, Rover owns Scott Bonnar.
However, Rover Mowers Ltd itself is an operating division of MTD Products Australia Pty Ltd. They state that Rover Mowers Ltd. designs, manufactures and distributes lawn and garden care equipment for both domestic and commercial users.
According to company history, (text courtesy of Wikipedia);
"Rover Mowers shut down its Australian manufacturing plant in Eagle Farm Queensland on 1 April 2007. Lawnmower production has commenced from their manufacturing plant in China.
Rover continues to have an Australian branch for spare parts, mower distribution and customer care."
