I realize they're made by the same company. The question I'm trying to decide upon is whether it's worth the money to buy the Gravley even though it's a bit more expensive and has a smaller deck and engine over the Ariens.

Gravley ZT 1840 XL

18 HP Koler Courage

40" fabricated deck

$3399

Ariens Zoom 2350

23 HP Koler Courage

50" stamped deck

$3199

My yard is about 3/4 an acre, mostly flat except for about 1/4 of it on a long sloping hill. Will I be happier with the better built Gravely or should I get more mower for the money with the Ariens?
