I ordered my flex deck last year. I installed it myself over the winter. Besides the extra deck, I have done some other things to the mower. Of all the things, I feel that flex deck is the greatest investement. I'll start from the beggining... Ordering was smooth. Came nicely packaged. Next was the instalation.... This was a chalenging part somewhat (it was onle my 3rd time welding) ....Somewhat time consuming task and perhaps the greatest draw back of the flex deck experience - Regardless, customer service was great along the way with many proactive calls. My first attempt to use it was spring of this year. My concern was that 15hp would not be enough. I was wrong, its pleanty. I keep my blades sharp and ballanced- over all with the deck I'm loosing about 100-150 rpms on the engine- barely noticebale. Besides the mower will clump (wet stuff) faster then when the engine will bog. With the lincage adjustment and bigger tires (18") the mower moves much faster while still giving a good cut. With half the season on the deck quality of cut is good (as good as exmark deck - unless you are cutting 8+ inches, then it suffers (Go slower) Durability - heavy duty. I expect it to last as long as the exmark. Trimability, you WILL be surprised how many places it will reach. Flex deck stays on the mower 100%, I only take it off when I use the mower to spray or spread. To take it off 22 sec. To flip it up (transport position) 5 sec Highly recommended. If only they could put them on at the factory, Every one in my town would have one.
