How many hours, or minutes would you EXPECT a dealer to let you use their Demo machine? Personally I'd love to try several brands of Z mowers (Dixie, Grasshopper, Hustler-no xr7) But the dealers here and/or the factory reps want me to "try it on a lawn or two" and that's it. After one Exmark demo I did a few years ago when I was point blank told to put no more than 2 hours on the machine, then last summer a JD 717 demo where I was allowed to cut ONE lawn while the salesman stood there waiting... Iv'e learned to ASK if I can try one for a day. Frankly I'd like the ability to have one on the trailer for a few days, to test it on challenging lawns where I know my current machine suffers. Also need to find out where I can fit a slightly wider mower and where I can't and if it's capable of mowing everything I need it to without having to switch machines half way through a particular lawn where I never had to before. I have a G-hopper front deck 52" with the bag type collection system coming to try out in the next week or so. I already asked about keeping it for a whole day once and was shot down. I'm not about to even think of buying something new again without having it on most of my current lawns. Opinions? Am I too unreasonable?
