8125 State Street, South Gate, California
James H. Lawlor of 8125 State St., South Gate, California, has
re-activated his four cylinder uniflow engine that he introduced in
1948. He has constantly strived to build a better engine, with a
few new innovations added. This engine can be used in many
applications too numerous to mention.
There is a real world need for a steam farm tractor, and his
present endeavor has been applying his unit to a No. 20 Cockshutt

work on in the near future, but for the present he intends to
supply the necessary parts to the best of his ability to any one
that wishes to build his own steam plant.
He operates a small shop, doing most of the work himself. He
hopes to contact some manufacturer that can really produce these
units in mass production.
He has built several types of steam controlled units, automatic,
semi-automatic and manual. He finds the manual type to be best for
This steam tractor is a manual operated type with a water level
