Hello ODK History Lovers

This is a story about another grand design in lawnmowers, proven grand by the 'test of time'.
After more than half a century, the Mastiff is still being manufactured (by Ransomes-Jacobsen)
and it still retains all key design features. The Mastiff carries on the tradition of the
heavy duty reel mowers started with the first petrol-powered lawnmowers of 1902.

I cannot attempt to address all the mark versions of this mower; I do address the first, Mark 1 design,
and then the present R-J 91 design for this enduring lawnmower.

The Mastiff was Ransomes' largest pedestrian (walk-behind) reel mower. It was made in two sizes:
30 inch and 36 inch from the early 1960s. It was equipped with a reverse gear because of its size and weight.
With a six knife reel it could deliver 65 cuts per metre, giving a superb finish on the sports grounds and
other large areas it was designed for.

It had a three-piece land-roll (with full differential) and a hand brake, again, because of its size and weight.
Options included a self-emptying grass catcher, trailing seat, and Junior Gang Mowers.

The Mk1 was powered by a huge 412 cc J.A.P. 4-stroke engine. When that engine became unavailable,
later Marks would be powered by the impressive Swedish MAG (Motosacoche) engine. If you would like
