Yesterday I mounted my tiller and was doing some test runs and it seemed the PTO engaged really hard and made the tiller jump when it engaged. I only engage the PTO at idle, but it still really bangs when it engages. I didin't remember this happening last year so I called my dealer as today is the last day of my warranty. They said they've never heard of a problem and said that's just how they are. I dropped it off at the dealer anyway because I don't believe that. Anyone else experience this?
