I'm back...need help again.

OK, this just didn't work out as I had hoped.... :fing20: Long story short, I've got about 3.5 acres of land. In need of a new mower. I convinced myself to cough up the extra dough to buy a zero turn.

I had what I thought was a great deal on a Toro Z4200 from Home Depot. It was a leftover model, got it for a steal. Turns out it has an electrical problem, so it's going back tomorrow, and I'm at square one.

Can anyone give me advice between these mowers?

Toro Z5000 w/21hp Kohler engine
White 50" ZTR w/22hp Briggs&Straton V twin
Craftsman 50" ZTR w/26hp Briggs&Straton Vtwin

All similar priced

Or....alternatively, any ideas what could be wrong with my Z4200? The battery goes dead after a day or two. And the battery is brand new, we bought a brand new one after the one in it was dead and not taking a charge.
