Series 9M1-9M46, 1939
The D5 9M was the very first tractor to bear the designation D5 and is extremely rare.
The D5 9M is basically a J series D4 with the D4600 Diesel engine fitted and rated at 45 D.H.P.
It was not until 1967 that the designation D5 was used again on a track type tractor, this time the 81H (Direct Drive) and 83H (Power Shift) machines which were rated at 75 Drawbar Horsepower (DHP).
The picture below is of a genuine D5 9M (There are some which have been made from components salvaged from other machines) in preservation in the UK.
