I have an older, side discharge, Landpride 84 inch finish mower. I can't speak for any other brand, this is the only one that I've owned or used. It's a well built mower. I've replaced the tires with solid tires so that I won't get any more flats, and I've replaced all the blades. They are real easy to replace once you get the mower up in the air enough to get under it. Blocks of wood work good for this. I also hit a stump and broke a spindle. It just cracked the cast iron house and I lost the bearings when it came apart.
Parts are easy to get from my local Kubota dealer. They just pull up a diagram of the mower and order what you need. In a few days, they are there. Prices seem reasonable, but again, I don't have anything to compare this too.
I can't image anybody not being happy with a Landpride mower. It sounds like a very good price and if it's in decent shape, it's probably a once in a lifetime oportunity.
