PART THREE - VARIANTS
The Adaptomatic sold for about four mowing seasons from 1956. In that time, it would appear that
there was little technical change to the machine. The main difference I have identified was to the
height adjustment arrangements on the lawnmower.

VERSION 1
Here is what I believe to be the very earliest model. It is serial number 230 and it appeared on
an auction site a few years' ago. Note the unpainted base with no ribbing between the front wheels.
Of particular interest is the total absence of the height adjuster knobs seen on later models.
I am unsure how height of cut was affected on this particular version:-

[NOTE: Version 1 appears NOT to have had the PTO feature.]

VERSION 2
The second version offered two height adjustment knobs: one controlling the rear wheels; the other
controlling the front. Not quite a 'one point' system yet ... Note the strengthening ribs in the base.

VERSION 3
The final version was really a consolidation of the designs into the one point system that became
the lawnmower design expectation by the end of the 1950s. This was achieved by conventional means -
a bellcrank and lever connecting rod.
