Was there ever a civilian version as an agricultural tractor or was one considered?
Seems to my memory that most of the extant hulls with drive-trains were former farming / logging vehicles that had their armor lopped off.
Certainly was. An Australia Company Stricklands put out a tractor version using surplus Australian LP Carriers, post WW2.
The Conversion was to cut down all the armour, put on a Rolling hitch and move the driver controls to the rear right. They were only a stop gap as they turned out to be not that suited to farm work.
I did a bit of research on these to put together a build of one in 1/35 using the Tamiya Bren carrier as a basis. which is a story in itself.
Short version is I went to the Warracknabeal Machinery Museum and asked if they had any photos of Stricklands Carriers, the old bloke said. "Sorry no photo's... but we have two of them in the shed !"
This build was done in 2005 and a classic case of "if know then what I know now" sort of thing
