Not sure if it's been mentioned but having liquid filled tires help hold hills, slopes, etc tremendously better. I was part of a commercial mowing business back before everyone was dragging one around (mid 90's ?) and after having to drag one of our Chariot's out of a local lake we took it to the CO OP and had them fill the rear tires with the same liquid we used on our tractor tires on the farm. I have the rears filled on dads Kubota and can scale a steep bank sideways with little to no slip. This is of course with aggressive tread and pretty wide rears.
As to owning a commercial zero turn I am typing this with a 21 year old sitting in the garage. Paid $6k in 2001 and drove it off the showroom floor. Pull start, steel deck, 52", and it's a war horse. Used it commercially and privately and other than your normal w&t parts its still trucking. Huge fan of them here and couldn't see myself on a big box unless I'm mowing a rock pile or winning a tractor pull at the county fair lol.
How about a little vintage mower love (see pic)
