Plan B on that purchase was a Husqvarna AWD number...looked like a hell of a buy/mower.
With a Honda engine, right?
I've seen the various AWD models on the Husqvarna, Club Cadet, etc. And man, those things have a lot of moving parts in their drive system that just make me nervous. I had a Yard Man years ago & it had this tendency to wear out the drive pulley that was on the crankshaft. It would be worn out w/in a month. That's all I see on those AWD systems, even though they have a pulley for each drive (front & back), what a pain in the butt.
My Snapper has solid axles for the front & back wheels, and the wheels sit on the axle with ball bearings. Very smooth & reliable movement that puts very little strain on the drive system along w/ the back differential. I'm now at the point in life that if I can get 45 mins of low intensity cardio pushing that mower around without the drive system engaged, I can get a solid cardio session out of it with my heart rate between 125-135 bps depending on how fast I go. Nothing like killing two birds with one stone, unless its three birds or more.
