I am looking to replace my current 50" Toro Timecutter zero turn with something a little bit more beefier. The Toro is fine but it not able to take the hammering of my yard(3 acres). I've heard good things about pretty much all commercial mowers and my neighbors have a Bobcat and a Scag and both of them swear by it. I've been looking at the Bobcat and Scag models and pretty much confused by what the differences are(if any). I wanted a 54" deck but none of the models have that. They have 52" and then next step up is 60/61". My current mowing time with the Toro is 2 hrs and with my neighbor's 61" Scag its usually down to around 1 hr. My question is whether the 52" deck is sufficient or should I just splurge for the 60". ?
