When I was looking I hadn't even thought about FWD because as you said, they are far and few between. I stumbled onto mine after searching for a 2wd model for several months. Didn't take me long to decide on buying it. FWD would greatly magnify your FEL abilities. Friend of mine has a 4610. The main difference between the 3910 and 4610 is a turbo added to the same engine. My friend says he doesn't need the turbo for the work he does. I really don't either. But I'm used to a turbo engine with my M9540. When I jump on the 3910 I immediately miss the turbo. You have to boost the rpms to get the HP out of a non turbo engine. But for what I do, I'm content. As to your ballast weight, I'd go at least 1000lb. I built a 3pt rack to store my suitcase weights on. So it serves dual purpose. It weighs 1500lbs or so. Makes a huge difference. I also use a Quick Hitch on the rear of my M9540 so it's easy to pick up the weight rack, use it for a few minutes, then set it down and go on about my business. Whatever you design and build for a ballast weight will be more user friendly if you add a Quick Hitch. Here's a pic of my 3910 with it's big brother. <img src="http://www.tractorbynet.com/forums/files/new-holland-buying-pricing/418161-price-check-ford-4610-a-20150306_141338-1280x720-jpg"/> <img src="http://www.tractorbynet.com/forums/files/new-holland-buying-pricing/418162-price-check-ford-4610-a-20150306_141353-1280x720-jpg"/>
