I've had personal experience with the ransomes bobcat. But all the other's mentioned are quality products. I think I forgot to mention LESCO.

The cut quality is typically much better than a budget rider mower. The top of the line $$$$$ Deere's and simplicity etc. would give them a run for their money. The only difference compared with a 21" push mower is it has smaller wheel marks.

My experience is with temperate area grasses (North East) Fescues & Kentucky Blue. Tycpical cutting height 2.5-3.5". I don't know jack about bermuda.

The dealers of the commericial mowers typically have demo's available. You can try before you buy (on YOUR lawn).
