Howdy y'all, Anyone use the flex-deck? What are your opinions on it? I have a 36 exmark metro belt driven. Would the cost of the flex-deck justify with the time I saved from mowing? In other words, is my belt-drive 36" exmark 12.5hp strong enough to pull that sucker? And does it really work as advertised? Independant reviews only please. If you manufacture it and tell me its great, that won't lead to half the credibility of an end user.
