Let me introduce myself first and say I am now in the lawn care business as it seems many people here might be. In fact I am a new home owner (as of last July). The house sits on just under a 1/2 acre with the front yard being completely flat with no trees and the backyard having a slight down hill slope with about 8 trees, deck, and is fenced in. Currently I'm using a small Craftsman push mower with a Honda engine, it's been doing fine but takes some time to mow the yard. So what I'm looking for is something that will provide a good looking cut as well as do it a bit faster. Last year I did use a couple times a 54" Craftsman mower but the deck was so wide that when turning around on some places in the back yard the deck would scalp the grass. So now I'm thinking a 42" or 44" would be better suited for my needs, I'm also looking at zero turn mowers and here's the list I've compiled thus far: Hustler Sport 42" Exmark Quest E 42" Bob Cat RZ 42" Gravely ZT 42" Bad Boy MZ 42" Of the list I've compiled a number of features to compare them all and plan on calling around for prices today. Exmark is huge in this area, in fact it seems like that's all you see on the trailers of the guys that do lawn care services, however the Quest E has a stamped deck and a C channel riveted frame. Hustler and Bob Cat both look very promising in terms of a welded deck and squared welded frame. But the small 15HP kawasaki on the Hustler and the Briggs on the Bob Cat both kind of concern me. Gravely has a stamped deck, and I'm not overly joyed by that. Bad Boy, I've never heard of has a year less warranty and just not sure how they compare quality wise to other brands. To end this long winded post, another feature that pulls a heavy weight on me, which I believe all of these are, is where the mowers are made... I'd prefer USA. With all of that said, does anyone have any feedback they could give me about the mowers or brands above OR do you have a suggestion for another mower which might better suit my needs? Thanks in advance.
