PART I


ITEM 1. BUSINESS

GENERAL

Donaldson Company, Inc. ("Donaldson" or the "Company") was founded in 1915
and organized in its present corporate form under the laws of the State of
Delaware in 1936.

The Company is a leading worldwide manufacturer of filtration systems and
replacement parts. The Company's product mix includes air and liquid filters and
exhaust and emission control products for mobile equipment; in-plant air
cleaning systems; compressed air purification systems; air intake systems for
industrial gas turbines; and specialized filters for such diverse applications
as computer disk drives, aircraft passenger cabins and semiconductor processing.
Products are manufactured at more than three dozen plants around the world and
through four joint ventures. The Company has two reporting segments engaged in
the design, manufacture and sale of systems to filter air and liquid and other
complementary products. The two segments are Engine Products and Industrial
Products. Products in the Engine Products segment consist of air intake systems,
exhaust systems, liquid filtration systems and replacement parts. The Engine
Products segment sells to original equipment manufacturers (OEMs) in the
construction, industrial, mining, agriculture and transportation markets and to
independent distributors, OEM dealer networks, private label accounts and large
private fleets. Products in the Industrial Products segment consist of dust,
fume and mist collectors, compressed air purification systems, static and
pulse-clean air filter systems for industrial gas turbines, computer disk drive
filter products and other specialized air filtration systems. The Industrial
Products segment sells to various industrial end-users, OEMs of gas-fired
turbines, OEMs and end users requiring highly purified air.

The table below shows the percentage of total net sales contributed by the
principal classes of similar products for each of the last three fiscal years:

YEAR ENDED JULY 31

2002 2001 2000

Engine Products Segment
Off-Road Equipment Products
(including Defense Products) 16% 16% 18%
Truck Products 8% 7% 14%
Aftermarket Products 30% 31% 30%

Industrial Products Segment
Industrial Air Filtration Products 16% 19% 17%

Special Applications Products 10% 10% 10%

The segment detail information in Note H in the Notes to Consolidated
Financial Statements on page 36 of the 2002 Annual Report to Shareholders is
incorporated herein by reference.


COMPETITION

The Company's business is not considered to be seasonal. Principal methods
of competition in both the Engine Products and Industrial Products segments are
price, geographic coverage, service and product performance. The Company
competes in a number of filtration markets in both the Engine Products and
Industrial segments and both segments operate in a highly competitive
environment. The Company estimates that it is a market leader in its primary
product lines within the Industrial Products segment. Its principal competitors
vary from country to country and include several large regional or global
competitors and a significant number of small competitors who compete in a
limited geographical region or in a limited number of product applications. The
Company estimates that within the Engine


2



Products segment it is a market leader in its off-road equipment and truck
product lines and is a significant participant in the aftermarket for
replacement filters and hard parts in its engine-related businesses. The Engine
Products segment principal competitors vary from country to country and include
several large regional or global competitors, and small local and regional
competitors, especially in the engine aftermarket businesses.


RAW MATERIALS

The Company experienced no significant or unusual problems in the purchase
of raw materials or commodities. Donaldson has more than one source of raw
materials essential to its business. The Company is not required to carry
significant amounts of inventory to meet rapid delivery demands or secure
supplier allotments.


PATENTS AND TRADEMARKS

The Company owns various patents and trademarks which it considers in the
aggregate to constitute a valuable asset. However, it does not regard the
validity of any one patent or trademark as being of material importance.


MAJOR CUSTOMERS

Sales to General Electric Company and subsidiaries ("GE") accounted for 13
and 12 percent of net sales in 2002 and 2001, respectively. There were no sales
over 10 percent of net sales to one customer in 2000. GE has been a customer of
the Company for many years and it purchases several models and types of products
from the Industrial Products segment for a variety of applications, the majority
of which are for use on their gas turbine systems. Sales to the U.S. Government
do not constitute a material portion of the Company's business.


BACKLOG

At September 30, 2002, the backlog of orders expected to be delivered
within 90 days was $172,668,000. The 90 day backlog at September 30, 2001 was
$182,591,000.

all commercial research and development is Company-sponsored.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
FINANCIAL DISCLOSURE

On April 18, 2002, the board of directors (the "Board") of Donaldson
Company, Inc. (the "Company"), at the recommendation of its audit committee,
dismissed Arthur Andersen LLP ("Andersen") as the Company's independent public
accountants and engaged PricewaterhouseCoopers LLP ("PWC") to serve as the
Company's independent public accountants for fiscal year 2002.

Andersen's reports on the Company's consolidated financial statements for
each of the years ended July 31, 2001 and 2000 did not contain an adverse
opinion or disclaimer of opinion, nor were they qualified or modified as to
uncertainty, audit scope or accounting principles.

During the years ended July 31, 2001 and 2000 and through April 18, 2002,
there were no disagreements with Andersen on any matter of accounting principles
or practices, financial statement disclosure, or auditing scope or procedure,
which, if not resolved to Andersen's satisfaction, would have caused them to
make reference to the subject matter of the disagreements in connection with
their report on the Company's consolidated financial statements for such years;
and there were no "reportable events," as such term is defined in Item
304(a)(1)(v) of Regulation S-K.

The Company reported the change in accountants on Form 8-K filed on April
24, 2002. The Form 8-K contained a letter from Arthur Andersen, addressed to the
Securities and Exchange Commission, stating that it agreed with the disclosures
set forth in the preceding three paragraphs.

During the years ended July 31, 2001 and 2000 and through the date of the
Board's decision to engage PWC, the Company did not consult PWC with respect to
the application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Company's consolidated financial statements, or any other matters or
reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.

REPORT OF INDEPENDENT ACCOUNTANTS




To the Shareholders and Board
of Directors of Donaldson Company, Inc.

In our opinion, the consolidated financial statements listed in the index
appearing under Item 15(a)(1) on page 7 present fairly, in all material
respects, the consolidated financial position of Donaldson Company Inc. as of
July 31, 2002, and the consolidated results of its operations and its cash flows
for the period ended July 31, 2002, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of Donaldson Company Inc.'s management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these statements in accordance with
auditing standards generally accepted in the United States of America, which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion. The financial statements of Donaldson Company
Inc. as of July 31, 2001, and for the two years in the period then ended, were
audited by other independent accountants who have ceased operations. Those
independent accountants expressed an unqualified opinion on those financial
statements in their report dated August 27, 2001.

shareholders' equity and cash flows for the years then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on

We conducted our audits in accordance with auditing standards generally
