About 2,200 Exmark Quest 42 inch ZRT Riding Mowers were made by Exmark Mfg. Co. Inc. of Beatrice, Neb., and sold nationwide from March 2009 through April 2010 for about $4,300.
The bearings supporting the riding mower's deck can fail, causing the deck to interfere with the operator's controls, the commission said in a statement.
The firm has received 18 reports of incidents but no injuries have been reported.
The recall includes 2009-10 Exmark Quest ZRT riding mowers with 42-inch mower decks, model No. "QST20BE422" and serial Nos. 790,000 through 860,652.
The model and serial numbers are on a metal plate behind the seat. "Exmark" is printed on the side and "Quest" is printed on the front of the mowers, which are red and gray.
Consumers were advised to stop using the recalled mowers and contact an Exmark dealer to schedule a free repair. Exmark has contacted registered owners of the recalled mowers.
Consumer can call 800-667-5296 for information.
