I sent this through the IPWEA site, but it may not have worked as I added a link.
My CBD cleaners currently use a Greenspeed gum removal machine in conjunction with a ride on scrubber.
They love the gum machine and while it was a massive effort at the start, now its just use for spot cleaning as they work along the street.
I also have had it for approximately 2 years without a single hiccup, touch wood. Being a rechargeable battery powered unit is very beneficial as it easily transportable and can be operated with minimal training.
The link below is from our local supplier, but I have seen Greenspeed gear used all around Australia so I'm sure there would be a fairly local distributor up north should you want to engage them for a demo of some sort.
