I need to get some feedback on grasshopper mowers. the 18hp 48" deck in particular. I am looking at selling my exmark because of poor/dishonest (we won't go there) dealer service. it looks like a solid mower, but the hydro setup is a bit different. if a wheel motor goes out, do you have to replace a hydro on this unit too? if any of you grasshopper owners could post a pic of the cut, I'd like to see it. for the people that use this model, is the 18 hp under powered for the size of deck? thanks.
