M135CDN Deuce with tracks

[Jes Andersen]

"As a boy in the 70's I remember visiting a farm and the fellow used his farm tractor off road in the sugar bush. It had a front idler/tensioner axle mounted under the transmission. I think there was a roadwheel on the ground. The tracks were two heavy woven belts with curved U-channels bolted in between, and the tractor tires rode in the curve. "

These were common in the oil exploration mobile seismic crews in norther Alberta in the '50s. I have pics of them and Bombardier half tracks in bush camps where they were working to 'discover' the oil that was much later 'rediscovered'.

The deuce setup has appeared in a few pictures and would have involved the same principle. Bobcats and skid steers today use tracks that go over the tires without adjustments other than tire inflation. The deuce could have used the same concept. Pictures, please...
