Good to see someone is looking after some of our military history Dave. Years ago, I think it was about 1969, I was driving big dozers scrub pulling in western Qld and came across a couple of blokes using WW2 tanks pulling light scrub. The gun turrets had been taken off and a big heavy flat canopy welded on the top. They didn't even have blades, just pulled a chain. They did it ok as long as the trees weren't very big.
