The Gas FORTY replaced the (gas) THIRTY FIVE in 1934. It had a slight increase in power from 38 D.H.P (Drawbar Horse Power) to 44 D.H.P.
Like most tractors of the period, the FORTY was made in two versions, narrow 56 inch (see below) and wide 74 inch gauge versions.
The track frames were now welded rather than riveted. The FORTY was made in small numbers as diesel tractors were becoming more popular.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
