Hello ODK History Lovers

The Scott Bonnar Model 33 is the ultimate chameleon ...
It changed its name [from Bonmow to Model 33]; its colour, and its transmission
[all-chain - belt/chain]; its engine, from 2-stroke to various 4-strokes. It re-invented
itself in the early 1970s to target specific mass merchandisers as the Lawn King.
The first Lawn Kings were a hybrid ... being a Model 33, but with some Model 45 bits.

The Model 33 was Scott Bonnars first viable attempt at a domestic 16" reel mower.
The small-sized Model 17 Supercuts of a decade before were clearly way-too-
expensive for the aspiring domestic lawnmower consumers of the 1960s.

The Model 33 corrected the main defect in the smaller 14" Model 19 introduced
in 1953: the lack of a primary clutch. The Model 33 re-introduced separate
clutches for reel and land roll, enabling the engine to be started free of reel
loading. It had the brilliant hair-trigger landroll clutch, now moved outboard to
be within a sealed transmission case.

The Model 33 would inspire the larger 20" Model 43. Both models would form
the basis for the later, renowned Model 45, in its three sizes. In other words,
the Model 45 consolidated what had been learnt through the successful and
un-successful features of the Models 19, 40, and 43. The Model 45 should be
considered more a refinement of the brilliant Model 33.
