The Hart-Parr"30" is very similar to the New
Hart-Parr in respect to the honey comb radiator, the open bull gears,
and the open valve cage and rocker arms. The
most noticeable cosmetic difference is the front casting just below the radiator.
The wording New Hart-Parr was removed and Hart-Parr
Co. Founders of the Tractor Industry, Charles City, Iowa, USA. was added
in its place. See front casting here. This
was the first tractor to be tested at the Nebraska Tests for the Hart-Parr
Company in 1920. The Hart-Parr"30" performed very well in
the tests and was on top of the list for for all other brands of tractors in its
horse power range. From this test on the Hart-Parr tractors sold well and
the reputation from this test carried on throughout the later models.
The engine and all other specifications remained the same as the late model New Hart-Parr tractors.
