G'day Jack,
I believe Kwikthatch was made by Kwik products, who make line trimmer heads and lines in the USA.
I also heard from mower agents that Briggs & Stratton brought the Kwikthatch into the NZ/AUS markets.
The tines are available from All Mower spares, which is good to know.
Mighty Mac make also make a de-thatcher to the same spec with the nylon tines. This is how I have found a relevant parts manual and operators manual for the machine.
I can't wait to use it in spring on my Kikuyu lawn.
