Item 4. Changes in Registrant's Certifying Accountant. On June 19, 2002, Kadant Inc. (the "Company") dismissed Arthur Andersen LLP ("Andersen") as its independent public accountants, and engaged Ernst & Young LLP ("Ernst & Young") to serve as its independent public accountants for the fiscal year ending December 28, 2002, effective immediately. The decision to change accountants was approved by the Company's Audit Committee of the Board of Directors and ratified by the Company's Board of Directors. The reports of Andersen on the Company's consolidated financial statements for each of the fiscal years ended December 29, 2001 and December 30, 2000 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the Company's fiscal years ended December 29, 2001 and December 30, 2000 and the subsequent interim period preceding the date of the dismissal of Andersen, there were no disagreements between the Company and Andersen on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of Andersen, would have caused Andersen to make reference to the subject matter of the disagreement in connection with its reports on the Company's consolidated financial statements; and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934. The Company has provided Andersen with a copy of the foregoing disclosures. Attached as Exhibit 16.1 is a copy of Andersen's letter to the Securities and Exchange Commission, dated June 20, 2002, stating that it has found no basis for disagreement with such statements. During the Company's fiscal years ended December 29, 2001 and December 30, 2000 and the subsequent interim period prior to engaging Ernst & Young, the Company did not consult with Ernst & Young regarding either 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 listed in Items 304(a)(2)(i) and (ii) of Regulation S-K.

Dear Sir/Madam:

The representations made in this letter are based solely on discussions with and
representations from the engagement partner and manager on the audits of the
financial statements of this registrant for the two most recent fiscal years.
Those individuals are no longer with Arthur Andersen LLP. We have read the first
three paragraphs of Item 4 included in the Form 8-K dated June 20, 2002 of
Kadant Inc. to be filed with the Securities and Exchange Commission and have
found no basis for disagreement with the statements contained therein.

Very truly yours,



/s/ Arthur Andersen LLP
Arthur Andersen LLP
