All of the low end ztr mowers you mentioned offer pretty much the same drive train. Low end residential engines, and Hydrogear ezt hydros. The decks will all be thinner stamped decks, where as higher end mowers mostly have fabricated decks that are much more sturdy. All of the brands you mentioned are designed for smaller lawns like yours. They may have a few different features, but will operate similarly. The reason some other members and I mentioned the Raptor sd is, because it is a much better built mower than the others for about $1000 more. It offers a better engine/ transmission than the other models, and has a heavier fabricated deck. As mentioned it is faster, and has a blade tip speed that matches the bigger commercial mowers (will leave a better cut). The Raptor Sd is a higher quality mower that should last much longer than any of the other brands you are looking at. It is more mower than you have lawn, but would you rather $3000 for a bottom of the line mower that may have to be replaced every 10 to 12 years, or pay $4000 for a mower that should last 20 or more years (if properly maintained)?
