I was looking at the Gravely HD, the John Deere 445, the Scag Freedom and also a Snapper. I ended up with....... drum roll.............. a Gravely ProTurn 148. I did spend a few more $ but I figure I would do better with a commercial mower. Got it home, started it up, ran asround the yard a few times to get a good feel before I start cutting grass, pulled the red button, made a 50' pass and smelled burnt rubber and smoke coming out by the left spindle!!!!!!!!! Stopped the machine, jumped off and saw the belt rubbing against the guard over the spindle. Called up my dealer and he said to bring her in so he could see what the heck was going on. Got to the dealer and after looking at the it determined the left pully was the wrong size. All the pullys on a 48" cut should be 5.5". This one was 6" which goes on the 52" model. Now what worries me is this came from the factory like that. Makes you wonder about quaility control at the Gravely factory. I spend extra money for a commercial mower thinking I would be getting a better quality mower but now i aqm second guessing myself. The dealer did change out the pully right away. He had to pull it off another 48" cut unit(the 48"HD home owner unit I thought about buying in the first place) Got home and it was pouring down raining. Might get to use it Sunday and then I could give you a report when I get to cut 2.5 acres.
