Roos shot for meat or "carcass" as it's known in the industry, MUST still have the skin on the carcass to be eligable for sale.
The carcass is then skinned at the roo works using a machine puller, and then the carcass is boned out.

Roos shot for skins have the skin removed in the field by the shooter or helper and then the carcass is NOT eligable for sale and must be left behind.
For many years most field skin removal was done by hand but as time went on various methods of field machine pulling were devised.
These included pulling the skins by using a vehicle and chains and later true "skinning machines" were developed.
Many were built by the shooters and some were powered by 12 volt starter motors and others were driven by small stationary petrol engines.
These machines were a vast improvement over hand skinning.

I first shot roos for a living in 1979 and made my full time living in the mid 1980's by shooting/trapping roos, foxes,cats and wild pigs.
When things went to plan, it was a damn good lifestyle!
