Yes it is possible to hand start these tractors by hand. Many years ago I see two farmers having a small bet on starting the diesel version. The diesel had a flat handle as I remember, just to the right of the stearing wheel and under the instrument panel, that when pussed down was a valve lifter/decompression lever. and yes one of the farmers did start it by hand. Again if I remember, with the diesel, you had to hold in a button on the left of the gearbox and at the same time use the gear lever to crank the starter motor
