Hmmm... how long should that take I wonder? We have had two 2500's and now two 3100's going on our fourth season... all have been much more difficult to keep straight than the previous two Grasshoppers I had for about 10 years and a Gravely that I had for a short while (granted neither near as comfortable). It took me about one cut to get use to the GH... now fifty-eleven cuts later and the Ferris mowers are still hard to keep in a straight line. 3 different guys have been driving them and we all agree. I guess maybe I have 4 really unlucky mowers or someone's putting something in our coffee.
