My yard is 1 acre and rather flat. I have been using a lawn maintenance company in the past, but I would like to start cutting my own grass. Therefore I need to get a riding lawn mower. I've narrowed down my choices to Husqvarna LTH18438 (http://www.husqvarna.com/us/products/garden-tractors/lth18538/) at about $1500 or (http://www.homereviewed.com/best-riding-lawn-mower/) at $1000. Which would you recommend as the best one for 1 acre? Is perhaps the Husqvarna overkill? I'm also concerned with maintenance. How often do riding mowers tend to break and what's their average lifespan in general? I prefer one that will last as long as possible with minimum maintenance.
