Though I am a bit surprised by the lateness of the model (1990s), I have managed to identify it, via the chute control screw design, on the John Deere online parts catalogue through the sectional view breakdown.
The model is the John Deere 826t.
The T stands for track.
The engine identifies as the Techumseh hmsk 80 (i will find the exact sub model today when I do a comprehensive evaluation of the machine).
In addition, there are no less than a dozen John Deere machines on Kijiji in Quebec with the same design and model identifier on the left side of the auger housing.
Finally, the Cub Cadet 826T from teh same era seems to be very much identical, except that the Cub Cadet had the steering track controls and teh auger was engaged via a lever on the side of the machine instead of on the handles.
