Probaly the BX would do all this.I have one that the wife drives. She mows about 5 acres a week. She all ready has almost 500 hours on a 2 year old tractor.On any tractor I would get a MMM.Don't have to take it off to use the 3pt hitch.I would be concern about that 60 inch rear blade.Seems kinda big,but I guess you have to use some common sense when you use it.But for only having one tractor I think you might be better off with something that is set up more like a tractor instead of a sub-compact.We bought this for the wife,she has a bad left knee.Works great for her,only use the right foot and it's low to the ground.I have a 40HP Ford for the big jobs.I think you might be better off with a JD or NH.I do plan on getting a Frail mower for the BX.We have pasture too and I think this would work better or hold up better with all the rocks and stumps.I want the wife to do it.She loves that BX.
