You need to take the Dealer with a grain of rock-salt. Ironically I have the same dealer on my Honda and my Ariens that thus far I've had two very much legitimate warranty claims - one on each. The dealer simply refuses to do anything and comes up with his own rules that stated I did that voided the warranty.
Example on HONDA deck got rust holes through it after two-years of three-year warranty -- they said You mowed the grass after you fertilized it....
My Ariens with less than five hours broke the PTO belt when I engaged it... No Warranty a stick must have gotten into it.
