Hi Max,
My old man bought an Ariens when they moved into their new place in Narre Warren. It was so steep my son asked them if they had bought the block by mail order. Can't remember how big it was but about a couple of acres. Up the front was reasonably flat but past the back of the house it dropped down to the creek and it was pretty steep, I found it difficult to walk up and down and that was 30 years ago but the old man was able to keep it cut with the Ariens. After he died my son used it for a few years at his place and now my grandson has been using it in his mowing business. It has the fixed front wheels and the one I have here has the swivel front. I feel bad for my old man because when he bought it (it was pretty expensive ) I just said "that's nice dad " and never went into the garage to look at it. They are a fantastic mower and well worth tracking one down if you want a robust self propelled mower. They are well worth fitting a brand new engine to if you find one with a worn out one
