Having owned a Gravely for 15yrs and being in the market for a new machine I was kinda set on going with Gravely again, like a Pro Turn 100. However, I see alot of love for the Scag QOC. Is it that much better than a Gravely or anything else for that matter? It does seem like most of the complaints on the Gravely are with the 60" + decks. If they are really having problems with the larger decks I thought I might go with a Scag if I go with a 60" but will consider a Gravely if I decide on a 52". I really want a machine that offers a quality cut with durability and longevity. I know from looking at the Gravelys they are built super tough. I have never seen a Scag in person so I don't know about their ruggedness. If Scag, which is the model to go with that would be comparable to a Pro Turn 100?
