Here is another implement which you may not of seen in the USA and might find very interesting especially as it is mounted onto a wide front unstyled Green Challenger, it is a rear mounted cultivator which operates from the power lift, it was made in UK by Miller (is this a relative of Steve and Sandy Miller?) I was lucky to purchase this piece of literature recently but do not know of any surviving cultivators, but great to see an original photograph of a wide front Challenger on steel here in the UK.

Millers were well known here for manufacturing aftermarket steel wheels for tractors in the 1930's and 40's,
