(More Info)
More Info: The unit is a Coldwell steam estate lawn mower and roller. These units were built in Newburgh, New York. The following two patent dates are on the mower - March 5, 1901 and August 19, 1902. The mower is unrestored at this time (2001). The unit consists of a liquid fuel fired vertical firetube boiler jacketed in copper with a copper smoke cone and stack, which provides steam to a small vertical double simple steam engine, approximately 2" X 4", with two bar guides, link reverse and crosshead driven boiler feed pumps. The engine and boiler are mounted between steel arched frames which also carry a copper twin tank for water and fuel, with the driver's seat atop the tanks. Roller chains drive a jackshaft and separate drives go to the mowing reel and the large under-roll; a small outrigger roll is provided at the engine end of the frame. Steering is by tiller. The steam engine is also copper-jacketed, and provided with ball-bearing big-ends; it is of steam automobile style. The mowing reel cuts a 40" swath. At one time Coldwell steam mowers were in use on the White House lawns. The mower belongs to Rough and Tumble and is not for sale. We would like to someday restore the mower.
