I've poked around a bit and tried not to be a pest (i.e. no posting but searching and finding almost everything I've needed), but I did somethign dumb and would like some input. Today I bought a new Honda HRX217HXA (homeowner with approx 1/2 acre that I mow). Like an idiot I didn't get the mower strapped down well enough in the back of the truck. All was fine until I pulled up the driveway and put on the brakes. I heard the mower roll forward and hit the storage box. The box is elevated, so the front part of the mower rolled under it, but part of the motor hit the box and did a bit of damage to the plate on the front of the motor. I'm embarassed to say that I don't exactly know what part this is, but it's unpainted aluminum with the "OHC" stamped into it. It didn't hit REAL hard, but hard enough that it has two vertical dents in it that correspond to the ridges of the corugated side of the storage box in the truck. So, what exactly is that part and how big of a problem is this? Give it to me straight! I did mow the yard and it ran fine as far as I could tell. The only thing I found odd is that even on the fast speed it would nearly die when I engaged the blades, but I don't know if that's the way they all are or not. Any help would be greatly appreciated!
