I'm in the market for a ZTR mower as I have 1.5 acre lot with a decent amount of tree's. I've pretty much come to the conclusion that I can't afford a commercial mower which is what I'd really like to have. So, I've looked at Toro Z4200 and Gravely ZT 1840 XL. These are both homeowners mowers so I know they're not built as good as commercial mowers. So I'm just looking for any opinions anybody might have on either of these two mowers. There is a slight cost difference - the Toro being a little less expensive then the Gravely. Thanks.
