                                    Part I

Item 1.  Business

     The Company was incorporated under the laws of Texas on March 4, 1902 and
since that date, has maintained its principal office and manufacturing
facilities in Lufkin, Texas.  The Company designs, manufactures, sells, and
services various types of oil field pumping units, power transmission products,
foundry castings and highway trailers. Lufkin manufactures four basic types of
pumping units:  an air-balanced unit; a beam-balanced unit; a crank-balanced
unit; and a Mark II Unitorque unit.  The basic differences between the four
types relate to the counterbalancing system.  The depth of a well and the
desired fluid production determine the type of counterbalancing configuration
that is required.  There are numerous sizes and combinations of Lufkin oil field
pumping units within the four basic types.  The Company's power transmission
products (speed increasers and reducers) are designed, manufactured and sold
primarily for use in industrial applications such as petrochemical, refining,
rubber, plastics and steel and for use in marine propulsion applications.  The
Company produces numerous sizes and combinations of gears.  The Company's
foundry castings are primarily customer designed components manufactured by
Lufkin for use in customer products.  Lufkin also produces various sizes and
styles of highway trailers, including vans, platforms, and dumps.

     The Company manufactures most of the component parts used in its Oil Field,
Foundry Castings and Power Transmission products and purchases the raw materials
and outside manufactured parts from a variety of suppliers on an order basis.
The Trailer Division generally assembles various component parts manufactured by
others. Inventories consist primarily of raw materials and component parts which
are generally assembled into finished products to fill specific customer orders.
These finished products are sold primarily by the Company's own employees.

     Oil field pumping units are the Company's primary products sold for export.
These sales, other than to Canada, are made principally through foreign sales
representatives, licensees and distributors.  During 1999, foreign sales
accounted for approximately 17 percent of the Company's total sales.

     The Company's domestic and international markets are highly competitive
with price, quality and speed of delivery being important factors.  While the
Company believes that it is one of the larger manufacturers of sucker rod
pumping units in the United States, manufacturers of other types of units
(submersibles and hydraulics)  have a significant share of the total pumping
unit market.  The Company does not believe it has a large market share in the
power transmission, foundry castings or trailer markets.

     The Company employed approximately 1,900 people at December 31, 1999,
including approximately 1,300 that were paid on an hourly basis.  The Company
has an open shop contract, which runs to October 7, 2002, with three AFL-CIO
labor unions.  The Company considers its employee relations to be satisfactory.

     Additional information required by Item 1 is included in the sections
entitled "Management's Discussion and Analysis", "Letter to the Shareholders",
and "Lufkin at a Glance" of the Company's Annual Report to Shareholders,
portions of which sections are incorporated herein by reference and included as
part of Exhibit 13.

Item 2.  Properties

     The Company's major manufacturing facilities are located in and near
Lufkin, are owned in fee and include approximately 150 acres, a foundry, machine
shop, structural shops, assembly shops and warehouses.  The Company also has a
plant in Nisku, Canada that produces structural parts for pumping units.  These
parts are then assembled with parts shipped from Lufkin and are delivered to the
Company's Canadian customers.  The Company also has a plant in Fougerolles,
France that manufactures, assembles and sells industrial gears and power
transmission products throughout Europe.

Item 3.  Legal Proceedings

    The information required by Item 3 is included in the section entitled
"Management's Discussion and Analysis" of the Company's Annual Report to
