You have 2 seperate issues to confront. First is choice of type and second is quality.
As has been asked how much area are you mowing ?
Is it flat, sloped, hilly, stoney ? Is the grass thick ? is it dotted with trees and if so how low do the branches hang ? Do you want to do other things with your mower ? What's your budget ?
For smaller blocks like mine (1 acre) the cox stockman were the ducks guts (not anymore rubbish since the takeover) with greenfield a reasonable second. I've got a rover ranger xc which you can't kill with a brick. It'll happily plough through whatever my block throws at it BUT it's a 5 speed not heel and tow so a pain to manouver, 30" cut isn't the quickest.
I am hoping for a time in the future, after I've moved to a larger property, when my father in law is willing to move his kubota B1750 on. They are worth about $10k in good order with loader and mid mount finish deck, which I THINK is 48" but could be wrong. He's got an air cooled same which I'd have in an instant. Obviously overkill for a small block.
Remember a lot of name brand stuff nowdays have moved production to india, china and other places and quality might no longer be what built the companies reputation. I believe deutz/same are now built in india for example.
