Hi, Folks.
Way back when, 1950s or thereabouts, an Australian company called Theiss Contractors built a small self-propelled scraper that they called the T-Man scraper. I have 'ackshully' both operated and worked beside one in about 1975.

They had a 2-wheeled tractor with a Perkins engine, hydraulic controls, a shaft-driven elevator and about 5 - 6 yard bowl.

Has anybody else heard of these jiggers and does anybody have any photos of them or know of any still existing?

A kew-ree-yuss mind would like to know.

Just my 0.02.

Theiss Contractors still exists, maybe contact them to see if they can point the way.

its not owned by the theiss family anymore they are now owned by a multinational company. they do have a company history project.

Hi, Fat Dan.
A German company, the name of which I can't remember at the moment, bought both Thiess and Leighton Contractors in about 1973.
