I've pulled much more than that with my SD60. But then, I didn't contact Hustler, I just hooked up, pushed the sticks forward, off it went. Did the job, put it away. No problems, no worries so far. The SD60 is now 4 years old.
Here is the next to last video I made about a week ago. It will show you the condition it is in. It does pretty much what I ask of it like the old MTD Yardman.
I believe you'll like a Raptor SD48. If you think you can fit a 54" on your property, you'll probably be happier with the larger deck. Further out the deck sticks from the side of the mower frame, better you can wrap the backside of the deck you can back the deck into places you can't drive into. Narrower decks won't allow that.
