Walk Behind Lawn Mowers

My lawn mower (HU725AWD, MODEL # 961450028 00, S/N 022316M009435) stopped working after one year of very rare and careful use. Last summer I used it every 3 weeks on my 0.6 acre lawn, and a couple of times this year, then it wouldn't start. I also got a letter about a safety recall of my model last fall. Right now the machine is in the repair shop with the Husqvarna local service center in CT, Benedict's Home & Garden in Monroe, CT. The dealer refuses to repair the equipment under the 3-year warranty, or the recall letter. Please contact the dealer and resolve the warranty/recall case. I would like to receive back my machine in working condition. I own other Husqvarna equipment, and I'd like to rely on the quality of your products.
