Consumers Digest revealed in its April issue that the Cub Cadet RZT S zero-turn riding mower is once again distinguished as a Best Buy in Riding Lawnmowers. Best Buys in zero-turn riding mowers are selected based on performance, ease-of-use, and quality of construction. Other criteria considered are features and warranty. The Best Buy rating extends to all RZT S models, which includes models with 42, 46, 50, and 54 inch decks.
