Handtools,
I just can't imagine anybody buying a mower with APE in the name, let along when they put a X behind it. That usually means: "Don't do it". lol. Kidding of course.
My Raptor has 12" wide rear tires along with 6.5" wide fronts which did make a huge difference in my purchase decision. Along with the deck build, parking brake lock in the sticks, engine cover, high end chair and a few other details.
The Ariens is a great machine and to be honest, I've never seen or touched an Apex, however, I'm certainly glad you're getting great service from your cutting deck. Nobody wants a clogging deck.
Please post some photos of your Apex, I'd love to see them so that I am enlightened. I've heard them mentioned here a few times, however, never seen any.
Thank you in advance,
Max
