I'm considering the purchase of a JD HD75 w/ 54 inch deck. Can anyone comment on my expectations for a reliable machine? Ease of operation and maintenance? Is it safe on slight inclines? Is theaddition of a riding sulky a good manueuver? (pun)The Eaton hydro trans....good? I'm looking at thisnew machine for the long haul...is it worth it?I'd sure appreciate any and all comments...tks much "genie"
